Nexus 7 Battery recharging method

Hello everyone, I just bought my Nexus 7 from Ebay (from an UK seller) but the wall charger for UK doesn't work here in my country so:
Can I use the PC to recharge it trough micro USB?
If I can recharge it in this way, recharging needs more time?

1. Yes, you can recharge over your PC USB
2. Yes, unless you have high output USB ports (default charger is 2A, most PC USB ports are 500mA to 900mA) so the charge time is longer.

Thanks,
this feature of my motherboard can help me in some ways? http://www.asrock.com/feature/appcharger/index.asp

You can only charge it if the screen is off or better yet if the device is off. Give it 12 hours for a full charge over standard 500mA USB.

Yeah, if you use your nexus 7 while its plugged in to the USB port of your PC you will loose battery, in Particularly if you are gaming lol. Mine when down from of 7% in 30 mins. Use a wall charger.

As I saild in the OP i cannot use that wall charger in my country

Surely you could buy a separate microUSB wall charger from somewhere in your country.

I've been using HTC and galaxy s2 charge. Had no problems and charging is very fast. Went from 30 to full in 2.5 hours

Thanks for the answer I will use the one of my note

You could always use a power adapter as well adapt from us plugs to your countries plugs

Chargers....
A Standard AC USB Charger will do the job in most cases, I'm using a powered Logitech USB Hub that just charges my BT Headset, my Galaxy S2 and now my Nexus 7.
If you want some faster charging times a Standard iPad USB charger plug should work, (they're rated for 2.1A instead of the 1A of the Normal iPhone chargers) just use the MicroUSB cable that you have and plug it in.
In response to your App Charger driver, it's probably that AsRock has built their USB ports and plumbed it in to higher +5V Amp line on your motherboard ie. they can deliver more power than the Standard USB Spec (500mA), I'm guessing at their 40% faster claim the port is delivering 900mA.
Good luck! The Nexus 7 has a 4326 mAh battery (ie 2.6x bigger than the Galaxy S2 Battery) so it'll take much longer to fill than all the Smartphones

Any idea why I can't seem to charge my Nexus 7 with my car charger?
i have both a generic Micro USB charger and I have one of the dual USB ports that you put into the cigarette lighter. It wont even acknowledge that I have plugged anything into it.
i have used the USB port to charge MANY different cell phones my old Dell Streak 7 and even a friends iPad.
Any ideas?

I think the N7 needs 2A to charge. a single USB is 500 mA and the dual 1A, so I don't think there's enough power.
Also check if the output of your microUSB cigarette charger is 2A

well i think that answers my question. thank you

This one will work: http://www.amazon.com/gp/product/B0090SVY3K/ref=oh_details_o02_s00_i00
It charges at the same rate as the stock AC charger.

The N7 is one picky device for charging. I have several chargers for the car that charge the iPad but not one will charge the N7. Same as AC chargers. This set works for me

This is what I use and it works just fine. I use it to charge my N7, GNote, Nook Color or my grandsons IPhone and it works equally well on all of them.
BTW, it prime available if you are a member.

It only charges via usb when the screen is off or when the device is off. Try plugging it in checking the battery % leave it awhile and then recheck the battery % you may find its gone up!

We can only use the LG charger?

Since the battery life of the phone is quite poor it's only natural that i would like to charge it when i'm on class or with an usb cable when im using my laptop, using other usb chargers/cables, but on the manual says (of course) that we should only use it with the lg charger that comes in the box or an official nexus 4 charger .
It kinda sounds like bullsh*t until i remember what happened with my motorola milestone, sometimes when i used another charger the screen started doing crazy things, like swipping the homescreens by itself , oppening apps, until i charged it for at least a few minutes with the official charger, some months later my digitalizer died, so you can imagine how traumatized i am, but then i think what's the point of trying to make a standard out of microusb chargers if we can only use the official charger? what do you guys think?

I find battery life to be very good.
I have been using an old HTC charger on mine without issue though. I suspect the 'only use LG charger' is to cover themselves in case you kill the device with a cheap and badly made knock off.

AW: We can only use the LG charger?
I have literally problems in draining my battery, running Franco's Kernel and Minco v6.
Anyway, using another charger should be no problem. I used the charger of my Asus Transformer and a mobile charger in my car without issues.

Feel free to use any USB wallcharger you'll find.
I tried some i had laying around (HTC, iPhone 5, iPad) and they all charged without trouble.. :good:

Yeah, I've used a 1A HTC charger with no issue. I accidentally left my lg charger at a friends house and had to use what I had.

the battery life is good, better than s2 with its extended battery, i was wondering about this too as i want to use a sony rx100 at 2amps to charge while im traveling.
on page 168 of the service manual it states the max charging current is set at 900mah, over voltage protection upto 28volts

The current should be controlled by the phone, not the charger. Therefore there shouldn't be a problem with more powerful chargers. The voltage has to be correct, though

The phone certainly regulates the power it takes.
If you are really worried about the chargers just flip them over and read the output ratings. Most of them are exactly the same these days.

P.s- the battery life on this device is outstanding, you just need to find the kernel that works well on your device

Any USB charger will work. Note the output current on the charger though, as that will impact how fast it can charge and whether or not you can have the screen on while you charge. The LG charger that comes with the phone is 5v 1.2a, an iPhone charger (at least as of the 4S when I got mine) is 5v 1a and an Amazon Kindle charger is 5v 0.85a. The USB 2.0 spec calls out a max power output of 5v 0.5a.

I'm confused , the lg nexus 4 charger is 5.0v 1.2A and my galaxy nexus charger which i use sometimes with my nexus 4 is 5.0V 1.0A , what does this mean? what's the difference?

My Nexus 4 is on the way so i cant comment on that but my Sony Xperia S acts differently to different USB leads even on the same charge unit. It might charge at 500mAh or 950mAh (on a charger rated at 850mAh), the screen might be fine or it might act erratic and it all depends on the lead plugged in to the charger

I used Samsung/blackberry chargers and they worked. Not sure if they were as efficient though.

I pretty much use anything but the LG charger and have been doing so over a month. So feel free to use any quality charger you like.
I also charge of my Philips Qi pad and off computer USB ports.
As long as it's providing stable power or anything close to it, it's good.
Just be careful with (fake) cheapo chargers. Those might cause issues with the touchscreen going haywire while charging off them. I've also read that about some car chargers, but so far my cheap 2A 2port USB car charger that came of DX is working fine for me.
YMMV of course. But there is no need to stick to just the LG charger.

Lost my charger. Which one to buy?

Self explanatory really. I realise any micro USB charger will fit, but I've read that of the voltage / amperage doesn't match, it can fry the phone. How true that is I don't know, but I don't want to risk it. I asked LG, and they directed me to their spares and accessories website. Initially it looked promising, but it turned out the website was terrible, was no info about anything.
I've had a look to find other 5V 1.2a (the specs of the charger that comes with the phone) micro USB chargers, but not had much luck. Any chance anyone could send me a link to a charger that matches the nexus charger? That would be very much appreciated.

I read something that said if you use a charger with a higher amp, that won't cause any problems at all. Is that true? So I could use a 5V 2a charger with the nexus 4 (the original charger was 5v 1.2a)?
The reason I'm so concerned is that when I use my HTC Desire charger (5v 1a), the screen stops working properly. I used it all the time when I first got my phone and the battery in the phone died, and I had to get it replaced. I don't want that to happen again, so I don't want to use a charger with different amp output.

Yes, that's true. The phone will only draw the current that it needs. A 2A charger won't "push" the whole 2A to the phone, the phone will just "pull" the 0.8A or so that it needs.

Order the Nexus 4 Wireless Charging Orb - Comes with Wall Charger & USB Cable (probably way Google doesn't just sell the Charger/Cable - to push the Orb)

Exactly. The amperage rating is what the charger can output based on demand of its load.

Is there no way to charge faster than ~250mA using "conventional" charging methods?

Is there no way to charge faster than ~250mA using "conventional" charging methods?
sorry for the newbie question, but i am loving this phone so far EXCEPT i have never been able to charge it to more than 60% so far because i dont have the original charger. and every single other method i've tried charges it around 200mA (measured by ampere) and it only goes up around 10% after 10 hours of charging
previously, i use a LG G3 and i get 1000mA via various methods like:
-plugging it into the computer's USB3 or USB2 port on the charging only mode
-using older "fast" chargers that range between 1.5A to 2.0A
I'm using a standard USB-C cable (bought from amazon) with the above
if i dont get the "newer" chargers, is there any way i can still charge the essential to a "reasonable" speed?

You can use one of the power delivery chargers (Anker, Aukey, etc) on Amazon. They will fast charge the PH-1. The charger for Chromebook Pro and MacBook also works well. Might also be able to get a replacement charger from Essential depending on where the phone was originally purchased. They sent me a free replacement charger and cable after the original charger stopped working.

I'm assuming "if I don't buy one of the newer chargers" means they don't want to purchase the official charger from Essential.

It sounds like you need a new cable or power brick, the cable being the likliest point of failure.

I'm using the following and all work fine:
LG G6 factory charger
Essential Factory Charger
Aukey wall charger with Quick Charge 3.0
https://smile.amazon.com/gp/product/B01FJ5TMC2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
AUKEY Amp USB Charger with USB C Port & 4 USB Ports
https://smile.amazon.com/gp/product/B01DZ4KHYQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
You need to buy a charger that supports Quick Charge if you want to charge rapidly.
Otherwise figure on nothing more than about 500mA.
At 500mA from empty figure 6 hours to charge.
Buy a charger.
