Can i charge thought USB or only over the Charger?
You can use usb but charge will be slower.

How can you use a USB Port to charge? It is not possible.
When I use both my computers for file transfers the tablet is never ever charging.
Depends on the amount of current your USB port can supply. I have some on my desktop that can go 1A that will charge it painfully slowly. My laptops won't give more than 500mA and never show charging when Tablet is connected

You are totally rigth, it's impossible ... with your computer.
With mine i can charge to 100% in about 12 hours.
It's (very) long but it (really) works.
Many quality USB wall chargers will put out 5V 1A. USB on a compiuter usually puts out around 5V .5A. Closer to the low end if your on a laptop, higher if your using a desktop with good power managment.
The tablet is set to charge either from 5V or 15V. Basically, if you charge from the supplied charger it will charge at 15V. If you charge with 5V it will take aprox 3x as long. If you have fewer amps then thats less current and less overall power getting to the tablet, meaning a longer charge time.
You CAN charge the tablet off USB from your comptuer, tho it can be slow. I have also seen intense games that cause the tablet to use more power than a 5V charger can supply so depending what your doing you may not be able to charge the tablet connected only to USB.

Hey all,
I often charged my g1 through a USB cable from my computer (rather than from the wall). When I do this for the g2x, it doesn't seem to charge. It either retains it's charge, slowly discharges (more slowly than if it wasn't plugged in), or if I am using an intensive app (e.g. pocket legends) it will keep discharging quickly. Is this normal or is this just me/my phone?
I am using the cable that came with the phone that I also use to charge through the wall (so not a cable issue).
Thx
It charges fine through my computer but keep in mind it will be a slower charge on any device. Maybe it's more slow than it should be on yours.

Did you try using other USB ports on your computer?
I've tried multiple ports and multiple computers (not multiple cables cause I only have 1, but the cable does charge through the wall adapter). I've left it plugged in to the computer for the past 2 hours with minimal use (basically just checking battery monitor occasionally) and I am losing ~2% charge an hour (I'll post a screen-cap after a few more hours of "charging").
mine charges.. very slow.
You should never charge your phone from a computer usb cable. There isn't enough amps to charge your phone while it is on and running. If you play games or listen to music while connected and charging from your computer's usb cable you will still run down the battery. The charger that came with the LG G2x is 1Amp or 1000MA! My previous Samsung Galaxy was around 700MA. Best way to charge your phone is to turn it off while it is plugged to the AC adaptor and use a high amp output charger like the stock charger. If you use generic ones with lower amp output like 500Ma, it will take longer.

The chargers for the gs and g2x both have the same amps. And Hz.
Where did you find that info?
Sometimes I still use my gs charger on myg2x. Both charge in the same amount of time.
But if it is true ill stop that right now.

I searched through some of the threads and I didn't see one directly related to my question so here it goes. I have been unable to get my tablet and or dock to charge with any other charger other then the one it came with. I'ver tried a samsun tablet charger, an 8w usb charger, other misc wall blocks etc. Will our tablet only charge with the asus charger? Any thought's or ideas on this would be great.

According to some it is possible to use a USB 5V charger to charge but you need the patience of Job and have it shut down. The simplest answer is that this tablet cannot be charged from ANY USB 5V power source.
The tablet charges at 12V 1.2A. The ASUS Charger is wired in such a way that when using the supplied cable it charges the tablet with 12V @ 1.2 A. When any other USB cable is used the charger will output 5V so that it can be used to charged other devices.
The only other source of chargers is from eBay. Just make sure you buy one that puts out 12Volts with a minimum of 1.2Amps.
There are other answers to this same question just maybe not the way you posed it!

Yes, the tablet (but not the dock) will charge from a 5V USB port, but it will be *very* slow (a few % per hour), and the tablet must be in standby or off.

The original charger outputs 15V.

Yes the original is 15V, it does actually switch to 5V if a non transformer USB device is connected. I'll add that a lot of the cheap eBay chargers output 11V to 12V which is why we have so many issues with the device trying to figure out what it is connected to.... imo.
A regular USB charger is 5V.
The tablet starts detecting a charge at 12V.
The original charger is 15V.
It CAN be charged from 5V, but you have to shut it down and it charges at 3-5% an hour. This isn't "some" mentioning it; it's in the bloody manual.
@sbdags If the cheap chargers indeed charge at between 11V and 12V, that explains the constant beeping people experience whilst using them. It keeps varying between "Charging" and "Not Charging".
So basically it sounds like the best way to charge is from the original charger/cable that came with the unit. This is no biggie. I was just trying to understand why a 8v battery back wasn't charging the tablet, but it wasn't idle, i had it on. So if I wanted to use that I would need to power off the device and it will essentially trickle charge. I don't see to many 15v usb car chargers on the market, though I haven't done extensive research. Thanks for the input.
It does charge (slowly) when on and idle - I regularly charge it overnight hooked up to my PC.
I bought a 1amp wireless charger. Now question is if my kernel supports fast charge and I toggle it on and plug this charger into USB on a computer vs the charger in the wall....will it still pull maximum output in amps the wireless charger could do. So it would be the same effect...through wireless?

Yeah, it'll take as much as the 500mah as it can from the computer and same goes for the 1amp wall charger. You just have to remember that wireless charging isn't 100% efficient, so 1amp input actually comes out to around 700~mah.

I'm not so sure about that. Fast charge detects a usb charge and treats it like a wall charge. But if the phone is charging wirelessly it's not plugged into usb. I don't think fast charge will have any effect on wireless charging. That's my understanding anyway.

Oh, I was talking about wireless charging in general. Not sure if it would work with fast charge or not though.
Guys,did u know how much time it takes for a full charge on Droid Maxx?
i leave it for 7 hours and it s 70%
is this normal?
thank u

It probably depends on the amount of amps the charger can push. The stock charger is about 1200 amp (or 6 watts), which is likely the limit the phone can pull. Are you using the stock charger or something else?
I've never timed how long it takes myself. I just plug in when I go to bed and unplug when I wake up. (Actually, these days I usually use wireless charging overnight.)
Are you using a wall charger or another device's usb port? USB is limited to 500mA for USB 2.0 (900mA for USB 3.0 ports.) Also a cheap 28 gauge USB cable will only put out 500Ma even if you plug it into the stock wall charger.

I use the fonas led on tip 2.1a charger. It charges from 30 to 95 in under 2hrs
Sent from my unlocked consumer edition Motorola Droid Maxx xt1080m.
i tried 3 different usb type-c cable including the one that came with the phone and it barely charges through pc or usb. i would plug it in at around 20% to my pc and 30-40mins later its at 20%.......... is this norm for everyone? its kind of frustrating when i do not have charger with me all the time
is it the cable problem? please help me out here
PC USB outlets do not give you enough current to charge today's smartphones. You need to use a wall charger with the right voltage and amp.

Ur pc will never charge it as fast as the charger does. However, your motherboard may have a software which speeds up charging. I have a gigabyte mobo and its soft named "on/off charger".
Its pretty much as the others have said. If the phone charges fine from a wall socket, Its most likely a PC problem.
Smart phones need a lot of power to charge them, usually 1+ amp
But, most PC USB ports (USB 2.0) will only give out 0.5 amp, so 'if' they charge it, it will be very slowly.
A PC with a USB 3.0 port should charge it fine, but not as quick as a wall charger, especially if it has a 'Quick Charge' feature.
