Is it safe to use a 2.1a 5v usb charger with the hox?
Will it speed the charging? (Stock charger takes 4 hours to charge!!)

It's safe, but it won't speed it up.
so 4 hours charge is normal? (With the stock charger)
I dunno, never timed it, but charging a LiPoly battery faster than that can shorten its life, and since its not removable, that would be a pain.

As Ben
said should be safe but won't speed up

One additional thing. Learned that the hard way.
Bought a HTC car charger. HTC supplied cable to that HTC car charger. Original HTC car charger on this charger sucked... despite showing AC charging
So look first when you charge if it says USB charging or AC. And then check how long it does to charger. Change the cable to the original one supplied with the phone if it's more as on that original stock charger

Well charging doesn't have 100% efficiency so a 1a charger won't charge at 1a, so a higher charger means you should get to the 1a limit but it's not going to reduce charging times enough to notice.

A charger rated at output of 1A should be capable of outputting at 1A. Of course, it will draw a little more power from the input than it provides to the output.
When charging, during the first phase (constant current) the maximum current draw is typically around 1A, for up to about an hour, then it drops off quite quickly when it moves to the second phase of constant voltage.
mine seems to charge to slow, or maybe cuz im not using the stock cable and im using my usb ports on computer
but if i have stock charger on wall outlet, how long is the charge top up take from 10% to 100%, thanks
yea mine is charging slow through the computer but I dont know if its because of the nexus 4 usb cable im using.

Obviously charging through a 500mAh USB 2.0 port would be slower then through a 1.35A wall charger.
can I use 2A charger?
Yes you can use a 2amp charger I was using my S4's and it charged fast

Interesting, I've only charged mine twice since getting it last sunday, and I've not paid any attention as to how long it's actually taking, one was through a proper charger, and finally today plugged into my computer
The New N7 ships with a 1.3 amp charger, and it's definitely slower to charge than the old N7 (which shipped with a 2.1 amp supply).
But I have yet to determine if putting a higher current supply on the new N7 will result in more current being delivered than the stock charger.

It takes about 3 hours to charge from 0% to 100% with the charger it came with. Using a 2 amp charger doesn't decrease the time, as the device will charge at a maximum of about 1100-1200 mAh.

Curious, do you know this from experience, or is there a technical document you could share?

Android Tuner battery history.
Can anyone tell me what the power draw should be using the stock charger and cable?
Battery monitor is telling me that it is +237ma, it is taking 12 hours to charge. I have sent back to Asus via PC world (what possessed me to buy from there I dont know) and they have told me there is nothing wrong with the device. I have flashed the stock image and still getting notoriously slow charge times.

About 1300 mAh.

With the stock charger and cable, the battery should be charging with close to 1200mA; the charger draws 7.4W from the outlet (at 230V).
There is current limiting based on the voltage the tablet sees, a USB cable with thin wires can drastically limit the charge current.
Hello,
The charger i've received with the phone seems to be cheap and not good enough, someone can recommend a good one?
Thanks
I'm using a blackberry original charger with 5v and 800mAh and this gives me ~3 hours of screen on during in ~ 40hours of usage.
In this time I make phone calls for ~1h ,I keep data on only in needed.screen brightness is set to auto75℅.I don't play games too often.WiFi stays on for about 20h.
I observed that using a lower amperage for charging,battery drains slower.original charger has 1.2Ah and charge the battery in about 2 h.this 800mAh blackberry charger does it in ~3.5-4h.
Try to charge your phone from a USB 2.0 port.it will take longer,but you'll notice some increase in battery lasting.
I use about 4 different chargers and they all do the same job for me. I generally look for USB chargers that can do more than 1Amp and that seems to work fine for my Optimus G.

i tried a cheap 2amp Charger (Russian copy or something of a Samsung Charger) and it worked oki for like 2weeks, but what i noticed was that it didn't charged my phone faster then the original LG charger (I am running CM11/Android 4.4.2)
Can someone suggest a decent car charger?
I have tried several types but they barely keeps the phone from discharging when screen and GPS are active.
Use a charger which has 4.8-5.0V output with 1-1.2A or 1000-1200mA rating. My phone charges up in about 2.5hours and lasts more than a day considering I use little amount of wifi, more of texting and less of phone calls.

I was using amb charger of 1 ah and it was good . Yesterday i bought hama twin port charger with original Nokia cable . Thats also a good combo . What matters most is keep phone temperature to minimum during charge . I ve noticed one battery temprature reaches 35 degree celsius or + , it would not charge and just drain .

im using this samsung note 2 charger.
5V 2A
its so fast
sometimes I plug in and I see slow charging. When I check battery status it's written Charging (USB) there. I unplug then plug in again and : charging (AC). What's the reason for that?
I'm using stock ROM and stock charger.

Does G pro port differ from G? I once charged a g pro with my charger. Can it be the reason?
great post, i want to buy a new one.
I use a anker 4 port charger with 2.4a. Device is fully charged in 1,5h!
1.5h with lg g3 charger and cable also.
~2h with original charger but with g3 cable.
I know this phone is Quick Charge 2 capable, but does that apply only to high voltage charging, or also to standard 5V?
I ask because I bought a 3.1A charger, and though the phone was almost dead, it didn't charge any faster than the 1.8A charger that came with the phone. Is the charger defective, or will this phone just not draw 3.1A at 5V?
QC2.0 is 9V at 1.2-1.3A.
Normal 5V is at around 1.7-1.9A only.
It will not draw anything more than what's above. FWIW, IMO, QC2.0 doesn't make a huge difference

Thanks. So QC is only a protocol for changing voltages, it has nothing to do with negotiating or handling a higher current draw?

QC is a protocol for allowing a maximum possible current draw at a predefined voltage. Just because you have a higher possible current supply from a charger it doesn't mean that the G4 will draw more.
E.g. G4 can only draw 1.8A a 5V. If you use a 1A charger, it can only draw 1A but if you use a 2A charger it will only be able to draw 1.8A and not the full 2A.
This phone is **** at charging 1% every 3mins at best. I'm at 44% 23 degrees Celsius and it says 2hour 4min to 100%. Ampere shows its only drawing 480ma on a 2A charger. Three cables.. Note 4 cable, Stock cable and a high quality third-party cable all the same. The cables work fine as they charge to Note 4 quick and a Tab 3.
I give up. I even put this LG poss on ICE to 18 degrees Celsius but still same crap. Night charging for me then. Even Note 4 quick charger can't help it.
Nice phone for sure but I'm going back to Samsung next upgrade, sorry LG.

What. You're using a **** charger. Get a proper charger. I know because I've tried mine on a **** charger, a Samsung Charger and an ASUS QC2.0 Charger. Nobody has the problems but you.

It does sound defective, unfortunately. Mine charges at up to 1%/minute, and that's without a QC 2.0 charger.
I use LG stock charger and a third party 2.1A charger to charge, Ampere shows that it has around 1000 mah. Apart from the charger, the charging cable quality do affect the result too. Try to swap cable and test again.
IMO﹐stock charger with 5V 1.8A can charge quite fast with 2+ hours to fully charged from 0 to 100%, no need to go for QC2.0.

I have found that my Original Samsung 2.1A charger sucks for the G4. Somehow it knows its a Samsung and doesnt want to provide anything over 1A. That charger charges at 2A my Galaxy S4. It takes like 3-4 hours to full charge from under 15%.
My LG G4 charges fkn fast with the original one and a Tronsmart QC charger. 1% every minute.
The title says all. Mention if you are using other chargers too like qc 4 or wireless charger please.
