High power charger - Nexus 7 Accessories

Are there any USB chargers out there that can supply more than 2.1amps?
I have the cheap 2.1a ones from eBay for my car but was wondering if there was anything bigger and have been unable to find anything on eBay.
Oh yeah only had my N7 today

Yes there are some rated higher but it's usually adding the total amperage of the ports together. A higher power charger than 2.1A will not charge your N7 any faster though.

Nexus 7 Car Charger

I was just wondering if anyone here has spotted a Nexus 7 car charger? Does it not matter if it's not specifically made for the Nexus 7? I'm trying to find one to buy online and I'm having some troubles. First post here I think I came to the right place though. :laugh:

Clicked thanks on accident lol. Any USB car charger should work, but I would make sure you grap a 1 amp one just so it has enough output to charge the tablet at a decent rate.
probably better with a 2amp one. samsung makes one for the tab2, about $12 on amazon, and just use your own microusb cable to connect to it.

Yup, go with a 2Amp one. Most of the cigarette lighter usb chargers are 2.1A.
Avoid the cheap Chinese 2+Amp car chargers, they can be so badly made they cause enough interference to wipe out your FM radio.
/edit 1Amp will be fine but don't go lower, the N7 would likely burn it out.
FYI I tried a 5v 1a wall charger and my gnex7 said f u wouldn't take the charge. 2a or nothing I say

Do you already have the Nexus 7? If so, can you take a look at the charger and see if rated at 1A output and/or try to charge it with a charger that came with your phone?
I am just curious if it can actually charge with less than 2A. The charger listed in the Play Store outputs 2Amps and I thought most tablets require 2A to charge.

Still waiting, should only be a couple of days now though...
I know this is something most people never do...but if you read the manual for the Nexus 7 it says you can charge it on a standard USB port with the Nexus 7 in sleep mode (no doubt because the power draw is much less). Standard USB ports are typically .5A...sometimes less. I would say that's the actual minimum. For the fastest charging 2A is what you want though.
The ASUS charger that comes with the N7 is rated at 2A (10W). I tested an old BlackBerry 0.85A (~4W) micoUSB charger and it seemed to work fine and the N7 didn't complain though I didn't do any scientific tests against the charging rates.
The 0.5A (2.5W) chargers probably won't even charge the unit if you're actively using it.
Cheers,
Kermee

Yeah...read my previous post...the manual says you can charge on a standard usb port (0.5A sometimes less) but only if the Nexus 7 is in sleep mode...ie you're not actively using it. If you can't charge it while connected to USB and it's in the sleep state...then your usb port is probably a low power USB port (<0.5A).
For those looking for a good backup battery charger for it...I recommend this one: http://www.amazon.com/gp/product/B005NGKR54/ref=oh_details_o05_s00_i00
works perfectly with my Nexus 7 (just make sure to use the correct USB out port on it as only one of them is 2A)
DealExtreme Charger
Saw this one on DealExtreme, even come with cable:
http://www.dealextreme.com/p/car-ci...-port-for-google-nexus-7-tablet-146751?item=8
Will be ordering will update when arrives. Also they're carrying Nexus 7 Cables in Pink, Green and Orange.
Was using a Sprint micro-USB plus charger (model PVX8823) with attached cable and standard USB port for 2nd device that I was using for my phone. Output is 0.65Amp which isn't sufficient and will slowly drain the N7 battery while in use. ~$35 at Sprint retail store. Wouldn't recommend for obvious reason.
Fortunately, had a spare Motorola SPN5400A 1Amp I bought with some screen protectors from Amazon because it was cheap like ~$5. 1Amp is sufficiently to maintain the charge while in use at near worse case running 3D games like Dead Trigger, Shadowngun, etc. So, 1Amp is minimum threshold.
You need a charger that:
1) Is capable of 2A (1.5A may be sufficient, 1A is a little too low)
2) Shorts D+ and D- together - This rules out most iPad chargers.
If it says it is made for iPod/iPad it will not work without modifications or adapters.
Samsung tablet chargers will work.
If you take an iPad charger, open it up, and short D+ and D- together, it will work.

Most chargers for android phones will work. I use my HTC charger for ,mine and I bought a car charge that has the standard micro USB connector but also has another USB port so I can charge 2 devices at the same time with 1 charging unit. You droid razor charger will work just fine. You just need to locate a charger that is capable of charging 2 devices at the same time such as this one

Check out this oem charger from Sprint. Its a dual port charger with a 2a output and you dont have to worry about buying a knock off charger that may or may not perform as expected. It also can be used as a wall charger. Good price too....

So are any of these confirmed 100% to work? the one a few links back (GTMax) says works with iphone, and I thougth that meant would NOT work with N7. So I am confused on what will work, and I am already on my 2nd Nexus7 being I blew out the USB trying a bunch of differnt chargers for the car.
I would like something that is small and can have multiple USB plugged in, but not a show stopper, just hope to find something on Amazon (Prefer Prime) so I can oder with my case today. Really want to use this in the car more (GPS\GoogleMusic..ect.), but with no power not a great option.
Thanks in Advance,

2A Charger Please

I have read countless threads and looked at many chargers and I just can't seem to find a 2a car and a 2a home charger. I just ordered this charger and this cable and it just doesn't work above 700ma. When I use the stock cable I get to 1300mah for a sec and then about 900 steady. This is on both ports. Someone please help me before I lose it! The only one that works at 1500mah is the cable and charger that came with my phone.

Thanks in advance.
Well, I can say from repeated certainty that this 6' cable charges at the same rate as the stock cable but is actually nice.

Also, my Qmadix car charger with dual 2.1A ports does very near stock AC levels when charging 1 device. My results are in the mega 2A car charger thread, but that's a spendy charger.

I saw a cable at Best Buy which is pretty nice, it has El Wire that flashes quickly(battery at 0-65%), slow (battery at 66-99%) and turns off when the battery is full. Would that cable be okay to use to charge my phone?

I have a cheap gas station 2 port usb car charger rated at 2amp for one port and 1amp for the other. Works great and I think it cost maybe 10 bucks. My phone charges at well over 1300mah in the car using a cheap usb cable I got at walgreens or some ****

I'm also looking for 2A replacement... How's the charging time compare to the stock Note 2 charger?
how do you measure the output while the device is charging? Is there an app to test how much juice is coming in real time?
I use a 2A HP Touchpad charger in my living room and a T-Mobile branded 3A dual USB charger in my bedroom (see links below). The T-Mobile charger charges my Note2 from 9% to 100% in less than 2 hours when I only use 1 of the USB ports. I'm not sure what the rate is when both ports are used. I've had this for a couple years and use it to charge (individually and simultaneously) my phones and tablets without any problem.

I've had better success with aftermarket than OE about 75% of time. Hence why I said it's more opinion based. Just like my Anker 3100 is better than the Samsung battery 3100 that came with the note 2.
99% of reviews anywhere are based upon the customers experience/opinions. Apple chargers always sucked for me. HTC chargers had many issues in the past.

I am not talking about reviews. I am making my suggestion based on science and comparisons to other chargers and knockoffs from china. If you're buying a flagship phone, buy a flagship charger. And a good USB cable. Cables make a hell of a difference in electronics that can accept more than 500mah charging.

I am talking about all chargers in general. OEM chargers are better than the belkins, tankers and whatever. I read a couple very good articles about how good or bad chargers are. The ones that come with our electronics are usually the best. USB cables vary, sometimes even within the same models. The Samsung and apple chargers are really the best value when you consider longevity, heat, reliability and some other factors I am not qualified to explain.

Yes perfectly safe.
Amps (current) are drawn/pulled, not pushed. More amps in a charger just means your phone can draw more without burning out the charger. It does not mean that the charger pumps out more than your phone can handle.
Volts are different. Too much or too liitle volts are harmful but all usb chargers are the same 5v so don't worry about that.
Lastly, unfortunately the different manufacturers have created different special schemes to trigger or allow devices to exceed 0.5 amps (to prevent a high draw device from trying to pull 2.0 amps out of a 0.5 amp usb port and burning out a usb port or possible even all usb ports on your expensive laptop!)
So, merely having a charger that says 2.1A on the side isn't enough by itself. You will still need to try differnt cables and try different models of chargers and even different kernels if you are rooted, or refer to reviews where the reviewer covered this explicitly instead of just saying "It worked great" which is a meaningless waste of everyone's time.
For instance there was another thread about chargers where they found that on a 2 port model that has one port labelled Apple and another labelled Android or just unlabelled, they found that they actually behaved different. The Apple port was 2.1A and the Android port was only 1.0 or 1.5A, yet a GN2 charged faster on the Android port. Because the GN2 didn't recognize the Apple port as being capable of high current, at least not with a standard cable, and so the GN2 was only pulling 500 or 700 ma, while on the Android port it pulled 1.0 or 1.5A.
So you really need reviews and testing that takes all this into account and specifies actual charging times and that make and model of the usb cable used etc. Or just buy the official stuff from Samsung which is all garanteed to match and work as expected without having to know all that unsuspected stuff.

I have quite a bit of cells and tablets, who doesn't, but I also have quite a few rc cars and helis. All the battery's we are using are Li-on although I use a ton of lipo (lithium polymer) on my rcs. Ive built packs, soldered connections, I charge 6 batteries in parallel, etc. I have a 530 watt adjustable 18 Volt 30 Amp PSU connected to a 400 watt 18 volt 20 amp balance charger. Granted if your not in the rc world this would be overkill for sure just to charge your cell battery. Point is you can charge any, repeat any Li-on or lipo battery at 1 C. . 1C is the capacity of the battery. All of my lipo rc battery's can be charged at 5C. That means 5 times the capacity of the battery. In our case the note 2 battery is 3100 mah or 3.1A for short hand notation. So if you have a big enough charger like I do, you can safely charge it at 3.1A in an hour. Some of my bigger packs are 6S 30C 10A packs. That is 22.2 volts 30C discharge rate and 10Amp or 10000 mah capacity and 5C charge rate. If your not familiar with the above jargon no matter, the OEM Samsung charger with the OEM usb cable that comes with it puts out 2.1 or 2100mah per hour or 2.1A . Our stock OEM batteries are 3100 mah or 3.1 A. So they will fully charge in about 1 1/2. Ive timed it several times and that is pretty accurate. This is with the phone being off not on while charging. It will take a little longer with the phone on while charging, about 2 hours. Hope this helps.

[Q] Battery drain while connected to car charger

Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.

Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

I think you need a bigger charging maybe the charger is not able to provide the needed ampere.

Thanks guys. I've ordered a 3.6A charger which had reviews saying it worked well for high power usage Android devices. So hopefully that'll sort things out. I'll post back my results.
OK, tried with the new charger and a good USB cable, and all is well. Even with GPS and Spotify running together the phone still charges slowly.

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.

Portable Chargers / External Batteries

I have the VS980 from Verizon.
Does anyone know if there are any portable chargers / external battery packs that will charge this phone without giving an incompatible or "slow charging" notice? If there aren't any that fast charge, are there any that slow charge? Slow charge would still be better than a dead battery.
I find the battery life is mostly great, but some days it seems to run down quite quickly. In any event, I'm going on a trip and may not have access to a charger during day and plan to be taking lots of pictures and videos and listening to music, so I'd like a back-up battery, just in case.
(curse Verizon and their non-removable battery...)
Anyway, there are threads for compatible car chargers, wireless chargers and USB cables, so why not add one for portable chargers / external batteries? Please list them here!
I purchased 9000 mAh portable charger from walmart online shop for about 70 to 80 dollars, and it seems to work fine. Its just bit bigger then other portable chargers, but ull never have to worry about battery with this monster.
I have tmo version btw

Thanks for your reply! Does this device give a "slow charging" notification?
I have both these and both charge at full speed:

http://www.amazon.com/13000mAh-Portable-Dual-Port-Thunderbolt-Incredible/dp/B00BQ5KHJW
theres also the E5 which is 15000mah, any anker that outputs 2a will charge the phone at full speed as the charger the G2 comes with outputs 1.8a
Not just amperage

The problem is, it seems that the phone doesn't just go by amperage, but also by the cable. The OEM USB cable has 20AWG wires, which carries a higher load, and cables which have thinner wires seem to trigger the slow charging. The only way to know if these chargers would charge at full speed would be to plug them in.
Has anyone actually plugged any of these in to verify that they do the full speed charging without a 'slow charging' notification?

Ive used all types of cables on my g2 with the chargers I listed they don't trigger slow charge. For me at least.
