External/Emergency Battery - Asus Transformer TF700

I was wondering if anyone uses any of those emergency charger... What do you think is the best one to pair up with the ASUS Transformer Pad Infinity? I was thinking of getting Sanyo's Eneloop Mobile Booster.Any more suggestion?

I've used them on phones before, but not one for my tf700 yet. Hope to soon once some options are out there that have been proven. I like choices.

I purchased the ZaggSparq 2.0 (it was on sale for 50% off a couple weeks ago):
http://www.zagg.com/accessories/zaggsparq.php
It is $100, but I got it for $50. I haven't actually tried it yet, but I'll give it a go tonight and report back.

how did it go?

Check out my review/mod for the Anker battery. On Amazon for $59 and it works wonders, can be used for all sorts of devices.

I use the Anker® Astro2 Dual USB Output 8400mAh External Battery Pack. The original transformer power supply uses a variable charger I believe that uses up to 12v/2.1 A to charge your device (it uses the max when your tablet has low battery life and less when it is near capacity).
My device is limited to 5V on either the 600mAmp or 2 Amp USB port. The tablet does not show itself as charging though when I use the device but my anker device blinks to show that it is charging. I turned my tablet off and left the charger in and the tablet gained a couple of percentage points of battery life after a few minutes.
I didn't know that the larger version could do 9 and 12V, feel like a bonehead for not checking. I got the 8400mAH version because I only wanted my charger to be about the size of my phone at max size otherwise I feel that the portability of the device is compromised (only have so much room in my pockets/bags).
If anyone else understands how charging works, I'd appreciate it if they could explain to me how using only 5v/2Amps would affect my TF700 infinity battery. Thanks.

Unfortunately 5v just isn't enough voltage to trigger charging (9v/2a isn't even enough). How long have you had your battery? Amazon has a good return policy, might be able to send it back.

Thanks for confirming. Sucks I bought the wrong one but at least the alternative is only a few bucks cheaper.

Welp, the Zagg Sparq 2.0 isn't even recognized on the tablet or with the dock. :/ Seems there's not enough output.
It works fine for my Samsung Galaxy S III, though.

another battery tip.

not sure if this is just a coincidence, but I did something by accident that has has improved my battery life. After trying many tips and apps like Battery Dr+ and with modest results. I tried charging with the HP touchpad charger that I recently got. It puts out higher voltage than the standard USB AC adapters. To my surprise , my battery charges super quick and holds a charge even better. Again, it could just be nothing, but my Triumph is experiencing extra battery life as well from the touchpads charger. Just thought I'd throw it out to see if anyone has any thoughts on it.
We should ask the mythbusters lol

USB is 5V, so I'd like to know how it is putting out more than that without damaging anything. Also, as I've stated numerous times (does anyone ever read around here?), the amperage output listed on the charger will have almost no effect on how fast the phone charges. The only time it will affect it is if the output amperage is less than what the phone will accept and the charger will limit output, but I doubt any charger with a power output below what the phone will take would be complex enough to do that.
Your phone will detect if you are getting power from a USB port or the stock charger. It will accept higher current with the stock charger. If you are charging from other charger, it will charge slow. To fix that, buy a new and cut open your USB cable. Short the 2 data cable.

The stock charger is rated at 5.0V/1.0A.
What is the HP Touchpad charger rated at?
I too have an HP touchpad and have noticed quicker charge times. Not sure about battery life though since it varies on my use. I cant use my samsung charger to charge the Touchpad, it says its not powerful enough.

from what i read, the HP charger is 5.3/2.0 Amps.
Not really sure why this would make a difference, since usb voltage is standardized and the kernel controls how much amperage goes to the phone. I once thought my Gtab charger did this, but imnuts pointed all the above facts to me.

Mobile battery packs

I'm checking out solutions for mobile battery packs that are compatible with the Tf700. I've just purchased a veho pebble 13,200mah battery (link below if it let's me)
http://www.amazon.co.uk/gp/product/...m=A3P5ROKL5A1OLE&pf_rd_r=0SZEM38A0PCXEMC434RR
While it didn't come with the right adaptor I figured I could work out the various connections. The problem is I've realised it's 16V whereas the original charger is 16v so the question is EVEN if I manage to figure out the connections, would using 16v potentially damage the tablet?
Thoughts appreciated

If it puts out true 16v then it could damage the Infinity. Measure the output voltage of the power pack with a multimeter.
The battery pack that I bought for the TF700 is the Anker Astro3 10000mAh. It has switchable output 5V / 9V / 12V. The TF700 will charge at 12v (car voltage). There was a brief discussion a couple of months ago about battery packs and what you will need:

I went this route using these USB adapter. Works well. You can use the tablet and phone on it at the same time; I was using my cellphone as a hotspot.
Thanks for the replies, I had already seen that post but I was hoping to be able to answer the 16v question as I had read in other places that 15v should be okay with 16v. I was hoping to get confirmation either way from someone know knew lots about electronics and voltage.
The main reasons for this are 1) I already have the battery 2) it's a brand I know and trust 3) It has a bigger capacity. However I'm a bit reluctant to using my tablet as an experiment so it's looking increasingly likely I'll have to return the veho pebble and pick up the Anker one.
Out of interest how long does it take to charge the Anker? From what I understand the input is only 5v so I'm guessing it's a good 6-8 hours? Also how long does it take to care the tablet itself?
Thanks
The first charge takes the longest, which is probably in that eight hour range. I haven't ran the Anker dead yet. I usually charge it back up after I used it, so it's fully changed whether dead or just a little. But it's a few hours.
The tablet takes about three hours or so from completely dead, assuming it's off. You can charge the tablet back up on the Anker.
I don't know about much on the electricity. I'm sure the tablet has a regulator of some sort, but couldn't say if 16v in would fit with in it or not.
There other larger battery packs like Anker. The problem is most don't have a way to put out the amps needed to register a charge for the tablet. Most just have USB ports, and limit the output to the normal .5mha that work with 90% or other usb devices.

Full power charging dock?

I want a charging dock for my S4 that will feed the phone the full amount of power that it can take, for quickest charging. I believe the stock charger that came with it supplies 2 amps.
I also would like said charger to have a slot for charging a spare battery at the same time.
All the charging docks I've found so far only claim to supply 1 amp to the phone, or less. Except one dock I found that did say it outputs 1.6 amps.
Does anybody know of a charging dock that will supply the full 2 amps? How about one that also has a slot for charging a spare battery?
Thanks.

Would you like it to serve you eggs and ham as well?
Damn.. you are really asking for so much and not nearly searching for it yourself enough if that makes sense.
There are charging docks that have a battery charger slot as well. They have a microusb port for power input. You can use a 2A charger with it and I believe it should be charging the phone at 2A but only when you're not charging the spare battery. I do not have the link as I saw it while randomly browsing through S4 docks on eBay. It's easy enough to find.
No, thanks. If it could cook my eggs and ham, it would be too bulky. LOL!
I looked through roughly 150 listing on eBay. I saw a whole bunch that said 1A output. And a few that were 700 mA, and at least one that was 500 mA. And exactly one model, available from a few different vendors, that said 1.6A output.
I did not see any that said 2A output. Just because the wall wart can supply as much as 2 amps, doesn't mean the charger will actually output that much to the phone.

My advice, is you should risk it.
If you're looking a product with such precise specs, I'm afraid you're not going to find it.
I messaged several different ebay sellers last night to ask if their charger is really only 1A and if they'll be having a 2A model. So far, I've gotten responses from 3 or 4. All of them have said sorry, we only have 1A. Please note, it will charge more slowly.
Update info. This may be old news to many, but here it is.
I had an online chat with a Supervisor at Seidio this morning. Their website has 2 charging docks for the S4 and neither lists charging output.
They told me that the dock will output whatever the wall adapter supplies. The charging dock is a passthrough. So, if I use the stock OEM charger with the Seidio dock, my phone will (allegedly) still receive 2A of charging current.
This may have been intuitively obvious to some, but it wasn't to me.
So, my quest is now much easier. Apparently, the docks I looked at on eBay that say 1A charging output must say so because the supplied wall adapter only provides 1A. And ones that say that but don't include the AC adapter are just making an assumption about that AC adapter you'll use.
BUT, though the phone charging port may be a passthrough, the slot for charging a second battery (on docks that offer that) would have the charging logic/circuitry built into the dock, so that could still be limited to 1A or less. At least, that's what I think. Could be wrong.
Regardless, i ordered a cheap dual charging dock off eBay that should be here by Friday. Using Galaxy Charging Current (a free app in the Play store), my phone shows 1900 mA charging current when plugged into the OEM charger directly. After I get the dock I ordered, I'll test that and report back.
If the dock will charge the phone at full speed, I can live with the spare battery being charged more slowly.

It's NOT a dock but a charger and it does come with an OEM spare battery. It charges a battery from 0 to 100% in about 4 hours, which is faster than your phone would deplete a battery, even when gaming. Paid $47, no shipping from Amazon
I see the price have changed a bit meanwhile but it's worth it if they still don't charge any shipping. Ships directly from Korea (made in Korea - both, charger and battery)

Hope it works out. The dock i ordered from seidio for my evo 3d did not charge at full power with the supplied adapter. I used a diff cable and power source and the results were better, but still not very good. Most nights I simply removed the cable and plugged the phone directly to it bypassing the dock, kind of defeated the purpose. I hope to find one that keeps the S4 charged.
Well, I received my eBay dock today, 2 days early. It is this one:
http://www.ebay.com/itm/111066155507?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
And when I plug it in and put the phone in it, I get a message that the connected charger is not compatible with this phone. And the phone shows a red X over the battery icon in the notification bar, and doesn't charge at all.
I tried it using the OEM charger and cable, the cable that came with the dock, and I also tried both cables using my OEM charger that came with my Note 10.1 tablet.
Exactly one time, when I put the phone into the dock, it didn't display a message and Galaxy Charging Current (app in Play) showed that it was charging at 1900 mA. But, several times before, and every time after that, it just displayed the message and wouldn't charge at all.

I've seen that and that's a big "no way". My normal deal is, if I run out of battery, it's because I'm out and about. Traveling on a plane. Riding my motorcycle. Whatever. Situations where I don't have the option to plug in. So, I swap batteries on the go and the charge when I get to where I'm going.
This charger on Amazon would require me to carry it, plus my phone charger, plus an additional phone charger to run the separate battery charger. If I were just going to share my phone charger between the phone and the separate charger, I would rather just have the phone on the charger and, when it's fully charged, swap batteries, to charge the next one - not swap the charger cable over to the separate battery charger.
if I were going to go the route of a separate battery charger, I would spend $7 or so on eBay on one of the ones that has a flip-out plug built in and plugs right into the wall. That is the kind I have been using for a while to charge my Rezound batteries when traveling.
The biggest problem with those is that they charge the battery at something like 350mA. Ridiculously slow!

...buddy, that's EXACTLY what this is. It simply gives you the option of charging another OEM battery (in the charger NOT in the phone) BEFORE you go out and about and then swap them as you need.
NO, it's NOT charging as slow as you suggest. They use a technology called direct charge which means that it draws as much (or as little) as your wall plug allows it. In other words if you plug it in the PC USB, then yes, you'll have to wait until you grow a nice thick beard, but if you plug it in your original 2A charger, it'll charge the battery from 0-100% in about 4 hours or less.

Absolutely NOT true:
1. You ONLY need to carry the charger if you plan on recharging the depleted battery BEFORE doing another swap - that's at least 12-15 hours on EXTENSIVELY using BOTH batteries - that's 12-15 hours screen on!!!
2. ONE phone charger can be used on either/or - you'll never have to charge them both in the same time (that's the idea with swapping the batteries, right?)

Up to you buddy, but usually you get what you pay for. The one I suggested comes with an OEM battery. I always suggest using this method over any battery pack as an OEM battery will ALWAYS give you just as much "juice" (this translates into running time) as the...yeah, you guessed it, the Original Equipment Manufacturer's battery. Although the battery packs manufacturers, they all claim huge capacities and running times, this mostly never holds true to the advertised specifications. It's called marketing

I don't think you're getting me. The point is, I get to the end of the day and I need to charge my phone AND the battery I used up. In order to charge both at the same time, using this Samsung separate battery case/charger, I would have to have 2 actual chargers. One to attach to my phone, to charge that battery, and one to attach to the separate case/charger.
Get it now?
More detailed:
- I start the day with 2 fully charged batteries. One is in the phone.
- I ride my motorcycle all day, streaming music via Bluetooth to my helmet, and talking on the phone while I'm riding.
- Before I'm done riding for the day, my battery dies, so I swap it.
- I continue riding, etc.
- I get where I'm going and I'm ready to go to bed.
- I now have a dead battery in one hand and phone with a partly depleted battery in the other hand. I want them to both charge while I'm sleeping.
This separate case/charger does not help me.

No offense, but I believe you don't get it. You say: "I need to charge my phone AND the battery". I should ask you then, do you still need to charge your phone and the BATTERIES (this is the plural, meaning two or more) should you go by my suggestion?
Either, or, if you're such a heavy user and you find yourself at the end of the day with 2 or more depleted batteries on a regular basis, then this becomes even more handy - admittedly, yes, using a second wall plug...or, again, if you're such a heavy user, then buy a 3rd OEM battery - case solved. (1 charger, 2 extra batteries, 1 USB cable, 1 wall plug)

You obviously didn't read my whole last post. Otherwise, you would understand that saying "I need to charge my phone AND the battery" is a short way of saying "I need to charge the battery that's in my phone (but not totally dead yet) AND the battery that I depleted earlier in the day."
And if I added a 3rd OEM battery (which you would also see that there is no need for, if you read my whole previous post), it still would not change the fact that, at the end of the day, I have 2 batteries I need to charge and only 1 wall charger to use. So, the separate case/charger still does not help.
If I charge the battery in my phone and then want to use my one and only wall charger to charge the battery that's in the case/charger, I may as well just swap the batteries and charge the second battery in my phone. Thus, I would save running down the battery that's in my phone while the other battery is charging in the case/charger AND I would save spending $50 on the case/charger when I just used my coupon last night and got an OEM battery straight from Samsung for only $20.

OK, now I did get what you were saying (admittedly, I didn't read the whole post initially) but I still believe that carrying a second set (wall charger + USB cable) would render a better overall usage time without compromising on convenience or quality (again, due to using a certified OEM battery). Think about it, the only "compromise" you're making is carrying another set - which is nothing, both in terms of money and used space/volume.
So, your on-the-go package would consist of: 1 Samsung charger, 1 extra battery and 2 sets of wall chargers/USB cables.
Now, we're getting somewhere!
Your alternative would cost me something like $70 for the case/charger (w/battery) plus a second AC adapter.
My alternative will cost me less than $30. $20 that I already spent on a second OEM battery, plus less than $10 for a wall charger like this:
http://www.ebay.com/itm/Charging-Cr...l_Phone_PDA_Chargers&var=&hash=item27d35082af
And I have less "pieces" to carry around.
Of course, the cheap wall charger won't charge the battery as quickly. But, I have been using a charger just like that for my Rezound batteries for a while now and it always seems to manage to get the job done overnight.
However, the PREFERRED solution is what I asked about in my OP in this thread. I want a dock that will supply full power to the phone and a spare battery at the same time. As I posted later in this thread, it now seems that most any charging dock should supply full power to the phone (as long as the AC adapter is providing 2A). Those docks still won't probably give full power to charge the spare battery, but I can live with that. So, with a dock like that, I would carry the same number of "pieces", but I'd have the advantage of having a dock to prop my phone up next to the bed, so I can see it.

Update info. This may be old news to many, but here it is.
I had an online chat with a Supervisor at Seidio this morning. Their website has 2 charging docks for the S4 and neither lists charging output.
They told me that the dock will output whatever the wall adapter supplies. The charging dock is a passthrough. So, if I use the stock OEM charger with the Seidio dock, my phone will (allegedly) still receive 2A of charging current.
This may have been intuitively obvious to some, but it wasn't to me.

I can 100% attest to this NOT being true. I have my OEM Samsung S4 2A charger hooked up to my Seidio Innodock Jr. at it receives a MAX of 1020mA. Yes, I realize it isn't the exact charger you are looking for since it doesn't have the spare battery compartment, but Seidio is NOT being truthful to you when they say that it is "a passthrough" dock. Just a heads up!

What are you using to determine your max of 1020A? Galaxy Charging Current? Battery Monitor Widget?

Both, they both display the same data - the BMW widget takes longer to update since I paid for the full version of GCC

I have both and they do not display the same data. As far as I can tell, GCC shows the actual full incoming current. OTOH, BMW shows the current being used to charge the battery.
When I plug in my OEM charger, GCC shows 1900. But, if the screen is using 100 and other stuff running is using another 100, the BMW would only show 1700.
So, as far as your post about the Innodock, if GCC shows 1020, then that's what I would believe. But, if it's BMW that's telling you 1020, then that could simply be because there is other stuff using almost 900 mA of current.
For the record, I looked through my BMW Usage log from last night when my phone was on the charger. The log shows every 5 minutes, I think. It only had one log entry where it showed 1992. All the rest were in the 1500 - 1600 range or less. And the phone screen was off that whole time.

Stock charger - charges slow and drops battery

Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?
My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.
The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

If i were you, i'll check with another charger doing normal stuff, if you still get negative charger maybe it could be your battery itself.

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.
First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.
I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.
Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

Get in touch with the retailer you got it from and ask for them to provide you with a proper charger, as a compensation

A bit hard to do since i got it from amazon.com when i was in the US (back in EU now) and there's no point in returning the tablet just for a semi faulty charger.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try
Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.
I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.

battery charger for k1

yes i read all previous post but no clear info. so i dont wanna spend 30euros for charger and i want to clear out what charger would charge my k1 "fast" and will charge even on gaming.
one of "cheap" but trusted brand is anker and i wonder if anyone try on it.
im lookingg this one.
http://www.amazon.de/Anker-20W-Lade...?ie=UTF8&qid=1452552283&sr=8-2&keywords=anker
does anyone using quick charge 2.0 on k1 model and works fine even when gaming while charging?
and also in manual comes with k1 under power rating it says : shield table 5-12 VDC, 2A

I have bought exactly this charger (exactly on this page ) and it works without problems with my K1. First I load my K1 on my PS Vita charger, but that get really hot, too hot, so I bought this anker one.
I think the loading time is ok, but it didn't break any records, for sure.
Oh, and there is a known Android 6.0 bug that drained the battery faster than the charger could load it, when you use the K1 while loading it. So we need to wait for an Update from NVidia. A workaround should be deactivating App optimizing and deactivating WLAN when the display is off, so it didn't drain it too much in standby.
fresh 'n rebel wall charger 4.8 amp & 24Volts total 2 usb ports with 2,4 amp i got it with mine it's only 20€ and i can charge my phone and shield very fast.
at the same time
Physically the 2014 and 2015 Shield Tablets [WiFi/LTE/K1] support Quick Charge.
However, the stock ROMs have not supported it since N 1.2.1 A 4.4.2 (last version it works) on the 2014 Shield Tablets [WiFi/LTE] and never on the 2015 Shield Tablet [K1].
Alternative Kernels and ROMs have enabled support for later Android versions.
Some users have had success with using such kernels/ROMs and some have not.
I've had good luck with several 2.0-2.4A 5v chargers. Make sure you have a good cable too or it may drop to 1.0A. This will cause it to drain during use even when plugged in.
I suppose I would recommend a Anker 2x USB 24W charger. ~$10. If you want to find a good cable they make some. Otherwise any <= 6ft cable with <= 24 gauge power wiring is what to look for.
I used stock K1 lollipop and quick charge working well.
you can buy any cheap brand support quick charge instore (I have one in centrecom when its sale to $15 for multi-charge)
