I lost my wall charger that came with my HP touchpad. The round plug thingie is what I'm looking for. Searching on Amazon brings up a number of items, for example:
http://www.amazon.com/HP-North-American-Charger-TouchPad/dp/B0055QYJJM/ref=dp_cp_ob_e_title_3
However, is there an alternative that works? I was able to use the Evo cable rather than the original HP sync/charge cable that came with the wall charger, but is there an alternative wall plug that works as well? Paying almost $28 for a charging cable seems a bit ridiculous.
Any help and advice would be most appreciated.
[[FOUND MY ANSWER]]
I found that Walmart was having a sale on the North American charger with the barrel wall connector for $11.99 and Meritline was having a sale for 6' long USB to micro-usb cables (pair for $4.99 no tax/shipping).
The listing on the Meritline page says that the cables are compatible with the Evo.
Given that the cable that comes with the HP barrel charger is pretty much monkey spit and fails within a month, I found a solution that works for less than $20.

Pretty much any USB charger will work, but most give a notification on the Touchpad screen indicating that they may not be charging. This is because the official charger is at the high end of both voltage and current capability. I charge from laptop, desktop and a variety of Blackberry chargers with no issue, but the available current will determine how long it takes to charge and whether it charges much while the screen is on. Go for a USB charger that gives you 2 Amps and you should be fine.

Thank you for the advice. To be more specific, can you recommend any alternative charging cables/wall charger units specifically?
Any brand name USB charger that gives off 2 amps should be fine. I tend to stay away from really cheap generic chargers. Any microUSB cable should be fine even a generic one if it has decent reviews. I worry about generic chargers since a poorly regulated one could send a voltage too high, but generic cables should be fine.
The chargers I am currently using, as well as the one that came with the TP, are the one that came with a Blackberry Playbook and the one from my HTC Desire HD.
The Blackberry charger gives an error on the screen that it may not charge the TP, but as it gives 2 amps, charges in pretty much the same time as the official unit.
The HTC again gives the warning and takes about twice as long to charge.
what about the nook color charger i know it higher amps might work as well

I just tested the TP with a charger for the NC, and unfortunately, it still gives the same "may not charge" warning...
There is NO after market charger that will charge at full rate like the HP barrel charger!
At best they will trickle charge at a much lower rate and take considerably longer to charge.
The TP relies on precise signaling which it will only get from the OEM item or specially modded after market units or cables.
Do a google for further info ie webosnation.com forums.
I think your looking for a 5.1v charger, aka rapid charger. This is used by the iPad, and some android phones like the Motorola droid 3, razr and htc rezound.
I could be wrong though,I haven't gotten my touchpad yet.but I do own all said device above (except the razr) and they all use the faster charging technology.

Don't believe all the hype about using ONLY the HP charger, there are many that do the job perfectly well. Too many people make these authoritarian statements and all they do is cause FUD.
At my office, I use the AC charger from my last Samsung phone (mythic) and it works IDENTICALLY to the OEM one. I have also used a Moto and and LG with NO PROBLEMS. I have no issues getting to fully charged in little time.
At home, my OEM cable is plugged into a high-power USB port (2.1A, I believe) and it has no problem charging from near zero to full as well. Front or top-mounted USB ports tend to be 500mA or less, but the rear ones (coming directly off the motherboard) tend to have a higher supply. I also use a non-HP USB cable occasionally and it works fine.
(I got my TP during the original fire-sale and have been charging it these ways ever since with ZERO ISSUES.)

The small voltage difference is marginal and isn't going to matter, the internal hardware should be able to tolerate a few tenths of a volt difference. In fact, I tested my Motorola charger rated at 5.1v and the Touchpad charger rated at 5.2v on a multimeter. The Motorola charger was outputting 5.20v and the Touchpad charger 5.16v. Granted this is at no load, but switching transformers are regulated so they should supply rated voltage at any current draw equal to or less than rated. Also depending on how well the voltage is regulated there may still be a slight AC ripple that the device has to deal with.
Does anyone know the time difference between using the TP charger and a standard droid/blackberry charger? Also curious if the charges last the same. I know theoretically they should since the battery is full either way, but electricals can be tricksiy..

Its all down to the charge rate that the TP is able to draw.
2A which is theoretically possible from TP AC barrel charger would charge the 6A+ battery of the TP from flat to full in approximately 6.5 hours.
If the BB charger were able to have 500mA drawn by the TP then it would fully charge in approximately 26 hours.
The charges would be no different.
To convert any regular USB charger into a TouchPad charger you need to add 2 resistors as per the diagram attached.
The presence of the resistors will trigger the TouchPad to draw the full 2A from the charger rather than the trickle charge it does when they are not there.
Please do not modify a cheap charger that is only rated for 500mA as you will most likely overheat it and it could present a fire risk.

Just pointing out that you need to start with a charger that is rated at least 2Ah to start with.
You can't turn a low rated one into a high rated one.

oh, for the love of gods. REALLY? I was just asking for a replacement cable. I don't want to reinvent the charging paradigm. I just need a simple recommendation for a cable. If a thread could be highjacked any further I don't know how it could be.
I appreciate all your "advice" but seriously, this is NOT what I was asking.
Anyone know if I can get a similar cable in the UK? Kind of lost my TP cable, and I miss the flexibility the long cable gave me, it was so much easier to use on charge!
well i know that my tbolt cable works. i have to use the tp adapter though. my tbolt adapter makes the touchpad say that the charger is incompatible.

Ordered a universal one with wall attachment and car attachment and when I connect the USB to microUSB cord the phone doesn't charge. Ordered another stand alone car charger and it, also, doesn't charge. If I attach the USB cord that came with the phone to the wall/car charger it charges fine. Both, specifically said for the "Nexus One". Is it an amp issue? Most microUSB charger in the mall cell phone kiosks won't charge it either. Is it a proprietary microUSB cord that I need or a matter of amps or something?
Why not buy from Monoprice.com?!
I ordered 8 USB cords (2/each of 4 different lengths), 2 Car Chargers, and 2 Wall chargers. All work perfectly fine, and I paid under $25. (Wife has a CLIQ, so we got plenty to work for both of us.)
So, I don't know what your issue is... Other than just not going to Monoprice

well I havent ordered from monoprice since customers got slammed with bogus charges... i guess i could give them another try though, but still... kinda weary
Why? I had over $1300 attempted to be spent at Newegg, and my CC company called me and stopped the charges. Got a new CC in the mail the following day. Some random amount at Apple as well. LOL. Fun times.
(Yes, it happened to me. I'm fairly confident it was from the same issue as others..) But, that doesn't stop me from using a company that makes good products, expecially when they just made such a big mistake. Odds are, it won't be happening again for a long while
Either way... Those are risks with online shopping. You just have to make sure that your method of purchase has fail-safes.
I have a CRAP load of mini USB chargers (all HTC stock) and didn't want to buy more. I bought a bunch of Motorola mini to micro adapters off Overstock.com for $2 a piece and couldn't be happier. I also bought the official Google cradle to avoid additional wear and tear on the microUSB port.

I bought a car/home charger from eBay when I had my Motorola Cliq, and my home charger would keep going on/off charging. I later found out that it was the voltage issue, where the charger was giving a maximum of 5 amps and the Motorola Cliq needed 5.1V or something like that.
But most chargers I've bought don't power the Nexus One. What specific voltage or amps should I look for it to have? The two I bought off of eBay specifically said they were for the Nexus One. Neither worked. Sellers are putting any micro SD chargers up for sale assuming they will change the phone. They will not. What technical spec will tell me if it really will charge it?
Could someone post a link to a USB charger that absolutely works? I just bought another one from Best Buy that doesn't charge the Nexus. Made by Rocketfish and is suppose to be universal.
Thats really wierd. Every charger i've tried works fine.
You're charger should be outputting 5V and anywhere from 300mA upwards. There is no max mA limit because the phone will only draw what it needs.
This might sound patronising, and I really dont mean it to, but when you say doesnt charge how do you know?
Do you mean from totally flat it won't turn the phone on and start charging it, or do you mean when the phone is on the battery indicator doesnt show a charging, and the LED doesnt go orange/green?
Or do you mean it never charges to full?
When I plug it in it's as if nothing happens. No light, no thunderbolt symbol on the battery, no screen wake-up, nothing. Nada. Now, the HTC wall charger and usb charger work fine. But if a MicroUSB charger calls itself "universal" it does not mean it will charge the Nexus. The HTC HD2 charger my wife has works fine on the Nexus though.
Hmm strange.
The charge process works like this:
- Charger plugged in causes voltage change on +ve USB line - potential charger detected.
- Phone draws minimal current (50 to 100mA) and tries to negotiate USB power
-- If that suceeds it tries to increase power to 500mA if the USB port supports it. If yes charging starts at 500mA, if not charging starts at 100mA
- If USB negotiation fails, it checks if D+/D- are bridged.
-- If D+/D- are bridged, the phone draws as much current as it can/needs
-- If D+/D- are not bridged, the phone draws a max of 500mA
There's nothing special about the chargers unless they have been wired in some special way for a specific phone. Thats why I'm very surprised these chargers dont work.
I know that if I chop a USB extention cable and cut out D+/D-, my nexus charges at 500mA. I've tried this myself for a totally different purpose. Thats no different to ground and power being wired to a 5v source.
Odd, I have three car USB adaptors and two AC USB adaptors.. All charged the phone, although only the AC charger shipped with the Nexus would do a fast charge, and none of my car chargers would. I found one that was rated 1Ah and soldered the two middle pins, now it works as a fast charger too.
The Motorola P513 car charger (OEM designed for a Droid) gives out 950mA, is super cheap (~$3+shipping), and works great for a fast charge with the Nexus One.

Thank you sir. I've been trying to find a car charger that guarantees a fast charge.
Just ordered one from Play.com for £3.99 w/ free shipping.
Maybe now I can use GPS for more than an hour...
I dunno.
My motorola charger for my old bluetooth (H780?) works fine, as well as the original google charger. I also have a car charger for my old bluetooth as well.
My suggestion, is to only buy name brand chargers?

Hi.
I'm looking for an advise about car charger that can charge my TF700.
does anyone confirmed that there any car charger that works?
I mean, I saw some posts that says that ASUS' charger is 15v instead of the more common 5v?
but then I saw the charger, it says " Output : 5v === 2A or 15v === 1.2A"
So I assume I can use other car charger that works with other tablets?
can someone confirm this for me?
THANKS
The tablet will only start to detect a charge at 12V.
Charging at anything lower than that will charge about 1-3% every hour.

oh. okay. any recommendation on what charger should i get?
preferably one with dual USB.
USB is not going to work, in any form or capacity. a USB port can only put out 5V at max.
I use a power inverter that puts out 230V (bought it for my laptop a couple of years ago) through a normal outlet. Plugged the charger into that and it charges normally. You could try looking into that.

YES the ASUS Transformer will only charge from between 12 & 15V. They DO NOT charge from 5V USB.
I have found that the car chargers which have the ASUS 40 pin plug attached to the cable work fine. They have a regulator circuit which outputs 12V at 1.5A minimum.
The ones available on eBay work well and aren't too expensive. They are a little bulky because of the high current circuitry so look at the pictures and make sure that it looks bigger than the average ones and you will do fine.
unfortunately there's no car charger available as of yet.

An Carcharger is avilable, i have one and it is working. 15v 1,2A Carcharger with normal Asus connetor. I'm usin it since 2 Month, never had problems. Carcharger is even cooler as the 230V USB charger while charging. Asus Tabel also switch immediately in charging mode. 14€ at Amazon.de.
By the way, why is everyone saying 5V won't work? On my 230V USB charger there's following note "15V 1,2A or 5V 2A"
Well won't need it, just buy this one ( which i have):
www.Amazon.de/gp/product/B007PQ8AN6/ref=oh_details_o04_s00_i01
Just ignore that tf700t isn't written there and that the charger would have 1,5A. Thats wrong, Carcharger has 15V 1,2A.
If you won't believe me, i can make an picture ( that it will have 15V 1,2A and works) otherwise have fun with it

Why aren't you reading everything? I said 5V charges too slowly for the tablet to detect, but it does charge. About 1-3% an hour, which is useless when you're using it. It clearly says, in the manual, that it will only charge over USB (5V) when turned OFF and not connected to the dock. RTFM.

I don't know how many different threads I have to post this in...
http://www.amazon.com/gp/product/B0081BFYY2/ref=wms_ohs_product
Includes a home charger, car charger, and an extra USB cable, that ALL work. I have been using these with my Transformer Prime, and now my Infinity without an issue at all, and they provide the ASUS required specs for charging and work just like the factory provided chargers.
I ran into this issue with my Verizon Samsung Galaxy Nexus. When attached to a charger, if I went into Settings...Battery... it would show the status of the charging process: it would say "USB" when connected to a computer, and charged at a much slower rate, or "AC" when plugged into the supplied charger in a regular outlet, and charged much more quickly.
With most car chargers, it would only show "USB" but there are some car chargers that have the correct wiring so that it was recognized as "AC" and charged as quickly as when plugged into a regular outlet.
I have two of these in my vehicles, and I just checked one of them, the one listed below first, and with the Tablet plugged into it, it shows as charging, as an "AC" source, just as with my Galaxy Nexus.
Here is the one I specifically tested and verified that it works:
Dual USB Car Charger
I do note the 2 negative reviews there, but all I can say is that I've had this one for almost a year, and it has worked perfectly for me with my phone. A brief test with the Asus Tablet confirmed it was seen as an "AC" charger.
This is the other one I have and which works fine with my phone, although I have not specifically tested it with the Tablet (I have no reason to expect it would behave any differently):
HTC T-Mobile myTouch 3G Car Charger
Obviously, I can't be held responsible if somebody else has a different experience with these, or has problems because of it. Just trying to be helpful and report what has worked for me.

It may work, or it may not. Drawing on my experience with the Galaxy Nexus, there were quite a few car chargers that had specs like this but which in fact were seen as "USB" chargers when used with the Nexus, and I suspect would behave the same way with the TF700T.
I am not an eletrical engineer, but it has something to do with how certain pins are shorted or not, and not all chargers that say they deliver the higher amperage will in fact do so with all devices.
It'll just take somebody to buy and try, and report what does or doesn't work. Per my post above, the chargers that work with my Nexus also work with my Tablet, in being seen as "AC" charging.

Don
I have one on order and will pick it up at my daughter's when we go to the US next month. Will post what I learn.
HOWEVER - a true "USB Charger" provides a 5VDC output, not 12- 15 VDC, as does the i-Blason unit I mentioned. Note that i-Blason states very clearly, "Warning: Pls do not use with other MP3 or smartphone... High Voltage could cause burn out."
The difference many smartphones (and other USB ported devices) detect in "USB Chargers" versus "AC Chargers" is max current available (<0.5 A vs >1.0 A) For example, I have a USB battery and a video cam that will both fail to illuminate the charging light if connected to a charging source below about 0.75 A, but still charge, albeit slowly. Both came with 1.5 A USB (5 VDC) wall chargers.
Since the i-Blason is a 12 VDC, not a 5 VDC output, the odds are high it will charge the Transformers at a rate very similar to the wall charger. At least based on electrical "theory". If I had to blind pick a third party car charger, the specs for the i-Blason, to include using the stock cable, were what influenced my choice.

Appreciate the additional info - will be interested to see if it performs as hoped. I suspect it will, especially based on that warning.
This is my first experience with wireless charging so I'm probably missing the obvious here so please, anybody, point that out.
I'm newly using a wireless charger with my N5 & performance just doesn't make any sense to me. It's the Korean/Chinese knock-off of the N4 Orb which others on XDA have used successfully. On basic charging it does work but I can't make any sense of these numbers:
Charging I get roughly 10% per hour -- not great, but okay for bedside/overnight.
Charging with daydream on (Dashclock) on I get a loss of roughly 10% per hour! Yes, the phone keeps indicating it is charging in spite of this heavy drain.
But sometimes daydream just turns off & it returns to charging -- this seems to happen if I start off with the phone (mostly) charged. For the most part though, if I leave the phone on the charger overnight with daydream enabled I'll wake to a nearly empty battery.
As I said, these numbers make no sense to me at all. Part of the problem may be the power source for the orb - it's only 1A but even if it's underpowered I can't see the drop from +10% to -10% /hour.
Second part of my query -- does anyone know if it would be effective (and safe!) to feed 1.2A to the orb & maybe get faster charge. Or maybe that would be enough to keep up with the Daydream drain?
FWIW the the USB charger (1.2A) is very fast, I get better than 1% per minute -- unaffected by Daydream.
im using this and mine gets full charge within 1 and half hours
Sent from my Nexus 5 using xda app-developers app
10% per hour? Something's wrong. A wireless charger shouldn't take much longer than wired.
It's possible your adapter is a dud. Try using the 1.2a adapter, it'll be fine. If it still isn't faster, you might have a bad charger.
Also, if it came with a USB cable, don't use it. The wires are too small to carry a reasonable amount of current.

So I'm using DashClock also and when it doesn't crash, my phone will charge just fine. Seems like about 3 hours total with daydream on, and about 2 hours with it off just regular charging. Here's my charger: http://www.amazon.com/gp/product/B00DOW1RD0/ref=wms_ohs_product?ie=UTF8&psc=1. Seems like you have a defective charger but it is a really weird situation.
Thanks guys, the jump to 1.2A made a world of difference! It still seems strange, but I guess there's a minimum threshold for the phone to properly charge. (I am really guessing!) Plugging the OEM charger into my qi orb I finally get a positive charge with daydream -- not fast, but good enough to wake with a charged phone! Without daydream I just got about 36% in the past hour.
A quick scan of eBay and the only 1.2A USB supplies I can find are refurbished LG & cost as much as the full qi orb! (from US with crazy shipping costs on these - I'm in Canada) But there are lots of 1.5A blocks, cheap (and free shipping from China). So... do you think it would be safe to try the 1.5A? According to Play the Google qi comes with a 1.8A supply but I have no idea how much the pad modulates the power or if that is all in the phone itself. It would be nice to have fast wireless charging, but with the dramatic jump with just the .2A increase I may be looking at something too powerful.
My concerns are (in order) 1. Don't want to fry the phone!
2. Don't want to burn down my apartment!
3. Would rather not trash the orb. The orb was inexpensive so I'm willing to gamble on point # 3.

I assume you mean USB out from PC since OEM charger is USB and orb power supply is USB as well. Point taken on PC charging though.

Thanks guys, the jump to 1.2A made a world of difference! It still seems strange, but I guess there's a minimum threshold for the phone to properly charge. (I am really guessing!) Plugging the OEM charger into my qi orb I finally get a positive charge with daydream -- not fast, but good enough to wake with a charged phone! Without daydream I just got about 36% in the past hour.
A quick scan of eBay and the only 1.2A USB supplies I can find are refurbished LG & cost as much as the full qi orb! (from US with crazy shipping costs on these - I'm in Canada) But there are lots of 1.5A blocks, cheap (and free shipping from China). So... do you think it would be safe to try the 1.5A? According to Play the Google qi comes with a 1.8A supply but I have no idea how much the pad modulates the power or if that is all in the phone itself. It would be nice to have fast wireless charging, but with the dramatic jump with just the .2A increase I may be looking at something too powerful.
My concerns are (in order) 1. Don't want to fry the phone!
2. Don't want to burn down my apartment!
3. Would rather not trash the orb. The orb was inexpensive so I'm willing to gamble on point # 3.

The official orb charger comes with a 1.8a brick. You should be fine.

I mean if your orb uses a USB cable and came with one, don't use the cable it came with. They're often very cheap and add a lot of resistance which will increase charge time.
It wasn't the step up to 1.2A that made a world of difference, it's using a quality adapter that made the difference. Your 1A adapter must have been faulty or grossly overrated. Sounds like it was putting out less than 500mA.
As for a higher amperage power supply somehow damaging things? Not possible. The circuitry in the wireless charger is only going to use what it needs, you could hook it up to a 50A power supply and it'll still draw around 1A. The N5 is also input current limited to 1.2A, so using a crazy high amperage adapter won't have much benefit anyway.
Still, not a bad idea to get a 1.5A - 2A adapter to compensate for whatever current the wireless charger itself uses. This is probably why the official one includes a 1.8A adapter.

10% per hour? Something's wrong. A wireless charger shouldn't take much longer than wired.
It's possible your adapter is a dud. Try using the 1.2a adapter, it'll be fine. If it still isn't faster, you might have a bad charger.
Also, if it came with a USB cable, don't use it. The wires are too small to carry a reasonable amount of current.

El Daddy & Mr. Sprinkles thanks, that's just the type of reassurance I needed!
just use the 2,1A amazon kindle charger with your orb... its cheap, safe and wont fry your phone

So from what I heard wireless charging, like a pogo plug can charge at a higher rate than the micro USB port in some devices (I've heard pogo plug can go up to 2.5A where the micro USB in that device is limited to 1.8A). So I'm wondering as these qi chargers get better, will this also be true. Mine is a 1A but seems like it charges around .8A so it's maxed out. I guess this also raises the question as to how fast is good for a battery also.

Gday All,
I realise that this topic has been mentioned in a few threads, but from what I could find, there is no definiteve fix.
Is there a way to disable this so that a non-genuine charger will work once the screen turns off, or if I was to root the device, is there then a way to do it.
Please dont flame me, I'm a total newb to android, and I dont mind admitting that.
Bit dissapointed that Samsung has sunk to this.
TIA!
Not sure what issues you are having but I have been using a few different chargers without issue. Which exact charging method are you trying to use (cable type, charger type, charger rated output voltage and amperage)?

The problem isn't that the charger is 3rd party.
The problem is that the device requires a 5.1V 2A charger or higher.
Anything lower than that is simply not powerful enough. You can find these specs in small lettering on the charger. Most cheap 3rd party launchers are 5V 1A.

I was one of the ones having problems with it needing to have the screen on to charge. It was a problem with the charger (yes, it was marked as a high amperage charger), changed to a different one (Anker 40W 5 port) and it's working fine.

Huge second on the Anker. I love that charger by the way. With various devices I would get irritated with some refusing to charge on certain chargers (my BlackBerry Bold in particular). I've since switched to the Anker 5 port 40 Watt and no longer worry about which cable I'm reaching for. Every device gets the power it needs with no fuss.

Initially i was using a belkin 2 port, 2.1amp per port charger, which would start charging but stop once the screen was off.

This seems logical, but it does work when i use the genuine charger from my sgs3 which is a 5vdc 1a charger. Takes all night to charge, but charges non the less.

Thanks for the info mate, ill see if i can get hold of one of these in australia, that being said, it appears that these are also 5v rather then the 5.3?

That's because the retention rate of the S3's charger is higher than that of a generic cheap 3rd party one. Where the S3 charger actually delivers 0.8-1A, the cheaper ones usually average around 0.5A.
This is why charging over a usb 2.0 port without any power boosts also (usually, there have been some exceptions) doesn't work.
I usually charge mine with my Note 3 or S5 charger, as the three are all the same charger.
So shortly after receiving my Nexus 6P I began hunting for a car charger that could supply 3 Amps if needed to my device...you know....in case of zombie apocalypse and the power grid goes down..I could still charge my phone :silly:
I found there were very few available. The first I saw was back ordered for weeks. Then I came across the Tronsmart charger. It was available on Amazon with Prime for like $22. The downside was it did not include a USB "C" cable, but now I see they have an updated version that has the USB "C" cable attached for a bit less. That'll teach me to rush out an buy something!
This is not totally a "con" since I am sure we have all been there where the cord attached to our car chargers breaks over time. So you would have the ability here to simply replace your 3 Amp USB C cable if that happened.
Testing: It seems the Nexus 6P is a little finicky and must be reallllly hungry (low on battery) for the charge current to get near 3 Amps. I drained my 6P down to 44% and tested the current on the manufacturer supplied charger in the house. It peaked at 2.85 Amps. I then took my phone out to my truck and threw it on this Tronsmart car charger. It peaked at 2.80 Amps. I am confident that this product works as advertised.
I also tested the type A port and it had no problem supplying 2.4 Amps to the 6P and also to my work phone LG G3.
This is a solid, rugged device. I am impressed enough to order a house charger from them as a back up for the one supplied with the 6P. It is designed for the 6P as well and also contains both A and C ports on it.

I have a ton of Tronsmart products, and I use the car charger daily without having any issues I wouldn't trust Ampere to give you accurate charging stats as far as the current goes, but charging time can be measured. The only true way to measure the current is with a multimeter and there aren't any C-C ones yet that work without a computer.
I have their dual port wall charger (both the A,C and A,A ones) and they're great! You can see my review of the chargers via my signature; if you have any questions about their products let me know. I speak with Tronsmart on occasion and I could answer any questions you might have.

Yeah, I tried Ampere and GSAM Battery monitor and both showed the same. I have a USB inline ammeter for the A port. I am very happy with the car charger and the quick charge capabilities.

I've been trying to find a more accurate way to measure the current being drawn from C-C chargers, but I haven't found one just yet. I was talking to a friend about making a C-C multimeter from a Raspberry Pi, or running a parallel wire from the C-C cable to measure current from. If we find a good way to measure it I will post about it, but so far I'm happy with mine too.
