just spotted this
http://www.qiwireless.com/toshiba-starting-production-faster-wireless-charging-chip/
Wireless charging at wired speeds. I am avoiding wireless charging due to the slow speed of it but if this thing works I wont need to avoid it anymore.
When available, would this work with an S5? It says it uses Qi as "its base for wireless charging". This is unclear to me, does this mean it is a Qi charger or that it simply uses some Qi stuff and then goes beyond it to provide the extra power, so it isnt actually Qi at all (if Qi is a standard then I assume this new thing doesn't confirm to that standard and so it isnt Qi, in which case it wont work with existing Qi devices?)?
What I would also like to know is does this new chip need to be in the phone itself, or would the chip they talk about be inside the back cover, or in the charging pad? Obviously if the phone itself needs to support this specific chip then its not going to be any good for s5 users, but if it is independent of anything in the phone and work would on an s5 then it may be worth waiting for it, it is apparently already in mass production so should be around soon I guess.
Based on the (albeit limited) numbers they provide in the article, it appears this is still a low-power Qi spec device like the ones we have today, which have a maximum output of 5W.
The wireless charging integrated chip will be following the Qi wireless charging standard as its base for wireless charging, which is great since this is currently the most used wireless charging standard for current devices. Along with this, the chip will be able to have a maximum output of 5 watts, which is comparable to a wired charger.

Unfortunately they say nothing about how this would differ from your run of the mill ebay Qi solution.
Mathematically (which admittedly is not my forte), if we assume "Wired" charging rate is 1800mA, 5W @ 5V requires 9W to hit 1800ma, which is outside the low-power Qi spec.
Then it is even more confusing as the entire article seems to be suggesting that it will charge at the same rates as wired chargers and much faster than current Qi systems.
Standard wired charging rate is 1amp, at 5v that is 5w
So if the new induction/wireless charger can supply 5w that means it will supply 1amp which is the same as wired
These will be roughly the same charging speeds
by the way, if you look at the charger your phone came with it clearly says "5.3V and 2A" so no the wireless charging will not compare to the conventional wired charging using your stock charger

This is correct, sorry should of also made my post more clear
5v 1amp is most common on many devices now and the qi statement relates to many devices so technically what they say is right BUT now some devices including the S5 do use slightly higher voltages and some draw more current now meaning wireless charging on our device will not be as good as wired BUT for most people that simply charge overnight it will make no difference
Those that charge overnight wireless charging will be perfect
Those that excessively use their phone and need as much charge as possible in short periods/quick charges throughout the day etc should use wired charging

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.
Links are below:

Meritline Cables (use this code MLCK222YNL1 for discount (cannot guarantee how long this code is good for, drops the price for a twin pack of the 6' cables from $10.99 to $4.99)

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.
I am going to buy a car charger for my new HOX, but it only has one 2.1A usb output. I know the charging current of the HOX wall charger is 1A, but I think 2.1A should work fine or even charge faster. But my concern is if the larger current would hurt my battery or shorten its lifetime.
Some ppl said the phone itself would take 1A current anyway due to some kind of threshold control inside, but I am not sure about it. So pls let me know if you know the truth. Appreciate it!
ps. I sent an email about this problem to HTC customer care 2 days ago but still no response yet. I will post the official answer when I get their answer.
UPDATE: Here is the official response from HTC about charging current, it seems that HOX does not intelligently control its charging current:
Dear yydnl,
Thanks for getting back to me, yydnl. The One X was designed with the intention of only using 5V 1A chargers. Anything more will cause damage to the phone over time. The phone was not designed to alter the current coming into the phone through the charger. I recommend that you only use the supplied HTC charger with your device.
Yeah I'd like to know. I never opened the oem charger and am currently using my bb playbook charger which shoots out 1.8A. I'm hoping the answer is no damage with a faster charge.
Yep, it'll work fine. Chargers don't "push" the charge, the phone pulls it. If the phone is only designed to charge at 1000ma, then it will only pull that current. So you could use a 10 amp charger and it will be fine, only difference is that with that high a capacity, you'll be able to charge 10 phones at the full charging rate. Changing the voltage, that's a different story.
Sent from my HTC One X using xda premium
There is no problem of the voltage of the car charger because that is 5V as the oem charger, but do you know if HOX is designed to intelligently pull the proper amount of current? or will it take any current fed to it?

All Li-ion batteries have intelligent charging circuits. Otherwise, it will simply explode.
I won't worry about 2.1A at all. The problem is other way around, i.e. whether or not the phone will take more than 500ma from your 2.1A charger. It depends on how your charger is wired. If the phone only detects a generic USB connection, it will only charge max 500ma. It requires special wiring from the USB port to allow phone to switch to AC charging mode to draw more current. Unfortunately, there is no way to tell until you have the charger and try it out. One thing for sure, those chargers designed for iPhone/iPad typically won't be recorgnzied by other phones as AC chargers.

Gotcha, the car charger I am going to buy is for iphone, but it also claims to be able to charge phones of htc, sony etc. So I guess it is possible to have the ac charging detection.

My money is on that it won't be recognized as AC charger. iPhone has special requirement on data PIN wiring that is not compatible with other phone. Yes, you can charge other phones but probably not at anything over 500ma.
Pls see my updates, it seems that 2.1A charger is not safe.
I was wondering if this car charger was safe to use on my Blaze (a Scosche 2 USB port charger). The info on it says:
input: 12-24vdc, 1.5a
output: 5v, 2a RoHS
(made in chine etc).
I have heard conflicting opinions about the use of third party devices for charging. Most notably, the T-mobile chat reps say they
"do not recommend" using them, but the ones on their very own website are mostly third party ones (at least they appear to be to me).
I have also heard that as long is the plug fits on the phone correctly it is safe.
Could someone clear this up for me? Will the scosch work and be safe? Or, could you recommend one that is safe to use on my blaze?
Thank you so much!
That will work perfectly fine. 5v and any amperage will be acceptable. The stock charger is good for 1A, so charging on a lower amperage charger will only increase the charging time.
I believe the Blaze will only pull around 1A max when charging, although a kernel tweak should be able to unlock fast charging in the future, if it already hasn't.

Thank you for your reply. Yes, it was the 2A output that concerned me after doing some reading. Can anyone confirm what the max amperage the Blaze will allow? I just want to be sure that 2A will not be a problem.
NOTE: It charged my old Iphone 3GS fine.
The charger does not "push" 2A to the phone, the phone draws as many amps from the charger as it can provide. The 2A rating just means that it will be able to quickly charge a device that needs that amount of power, like an iPad. Most phones will draw between 500ma (.5A) and 1A.

its kinda like bandwidth... the charger doesnt push 2A, the charger's bottleneck is 2A. If the phone charges at 1A, only 1A will be going through the charger regardless of the charger's 2A limitation.
At least that's how i think it is... its been a long time since my Electrical Engineering portion of Intro to Industrial Maintenance in highschool....
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

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.
Advice / assurances / suggestions? Please.

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.

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.

Hi guys,
My LG G3 has uses a charger that outputs 5v 1.5mAh
I have a USB charger here that outputs 5v 2.1mAh (used for my GoPRO highcap batteries)
I've been using this 2.1mAh charger for my LG G3 and everything works great. But I'm beginning to worry if this is damaging my batteries or phone in anyway?
and to push this question further, is it safe to use even higher mAh? i have a 3mAh usb charger here as well but im afraid to use em.

and to push this question further, is it safe to use even higher mAh? i have a 3mAh usb charger here as well but im afraid to use em.
Thanks

As far as I know, current is drawn from the device, not pushed from the charger.
Almost all modern devices limit the amount of current they can draw from the power supply in order to protect the battery and the inner circuits. The amperage of the charger just tells you how much current it is able to supply, not how much current it will supply to the device it is connected to.
If you plug a 2.1A charger to a phone that limits the amount of current at 1.5A, it will charge at 1.5A.
If your phone has an amperage limit (which is most likely the case), then you're fine.

ONe of the main reasons I wanted to use a 2.1A charger is because LG's wireless charger keeps getting "slow charging" notice.. i theorized that perhaps the "wireless range" could be increased if i used a higher amp charger.. does this make any sense?
Although I have noticed much lesser "Slow Charging" warnings now..

I'm not sure I understand what you're saying here, you threw me off when you talked about wireless charging. Were you talking about plugging the 2.1A charger to the charging pad or plugging it directly into your phone? Either way, it all comes down to the maximum amperage a given device will let through.
If you meant plugging the higher amperage charger to the charging pad, the result will be the same, as it is very likely that the pad also has current limiting mechanism. If the current flowing through the charging pad coils is set at a maximum value, then the magnetic field created by the coil and the current induced by this magnetic field inside the phone will also be set at a maximum value, thus charging the battery at the same rate, regardless of the wire charger output (unless, of course, the charger can handle less amps than the pad [or the phone], in that case it will charge slower).
I don't really know why you're getting the "slow charging" warning, I've never used wireless charging before, but i do know that the position of the phone in relation to the pad is very important, because the strenght of a magnetic field decays strongly with distance.
I see. Wow thanks for the knowledge share.
BTW, sorry for the confusion, I actually meant both. I have a wireless charging dock that gets the "SLOW CHARGING" warning frequently w/ the original cable and charger.
So I replaced that cable w/ the 2.1mAh w/c I use for the wireless charger most of the time, but occasionally plug the usb cable from the wireless charging dock directly into the phone (for an even faster charging = when I'm in a hurry)

Do you notice any difference when charging directly with the 2.1mA cable and the original? There shouldn't be any, unless the original is rated at a lower amperage than what your phone draws, which doesn't make much sense.
