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
Hi guys,
currently having a problem with my xbox 360 charging my Nexus 4...
basically i put my nexus on charge (usb cable from xbox 360) over night and it clearly said its charging, so i woke up the next morning and the battery % was as i left it, but it still clearly says charging? this has happen to me twice this week... has anyone else had a problem like this?
forgot to mention, i have always charged my mobile devices using the xbox 360 and never had any problems before...
Maybe try other cables?
I have had similar issues with phones in the past where certain cables worked and some didn't.
accidently gave u a thx I had this problem with all my phones trying to charge them with my PS3 or PC. With my PS it charged 1-2% and with my PC a bit slower than normally. I think its the bad electricity supply over usb

I had similar issues while charging through my laptop, My phone would say charging, meanwhile it would be discharging
I think it has to do with the phone using more power than the port is giving out. Basically some apps you have one your phone is using so much battery that the charger is not charging because the required power to run the phone is greater than the charge is giving. I'm thinking this is becasue the phone has so much RAM that all the background apps are using more and more power. It's like charging a Laptop through your Xbox USB port, the laptop uses WAY too much power for it to be getting charged through a measly USB port.
Nonetheless, I stopped charging my phone through my laptop and just plugged it in the wall. It charges way faster anyway (my charging usually takes 2 hours when it's really low to full battery)
Even if it does charge, it's not likely to charge well; the Nexus 4's charger is 1.2 amps. The Xbox USB ports likely put out less than half that. Unless you have an S model, in which case the rear "Kinect" port is "high-powered," which likely means 1.0 amps.
I'm charging off my AirPort Extreme without issue...albeit it slow. Since I charge at night, it's a non-issue. OP, have you tried swapping USB cable?
Does the Xbox 360 temporarily disable its USB port if you try to pull to much power from them?
The Nexus 4 requires more than what is supplied...
uberSlackr could be right, normal usb ports are 5volts,500mah, so 5 volts standby, you should be able to charge even at a slow rate, windows 7 has an option to turn off usb ports to save power unless you disable it.maybe xbox has a similar power saving function.
samsung s2 max charging rate is at 650mah, my nexus charger is 1.2amps, so 1 amp draws too much.

yes, i've tried changing the cable and its the same... i believe the comments above have explained it much clearly to me and make me understand why its not charging (xbox usb being 500 mah and the phone needs 1.2 amp... so looks like i will have to use my wall charger from now on)
i appreciate the help guys!! :good:
I must be doing something wrong, but can't figure out what
I wanted to enable fast charge, cause my device drains more battery than it charges, I installed the "fast charge" app from the play store, but it always says my kernel is unsupported.
I've already tried these kernels:
-franco (franco kernel updater)
-fugumod (fugumod updater)
-trinity (trinity kernel toolkit)
-faux (fauxClock)
-timur
and I've searched in each app for a place to switch it on but couldn't find it anywhere.
I'm running cyanogenmod 10.1
the tablet is rooted and unlocked.
anyone any idea what could be the problem?
thanks for your time!
Give NCX Kernel a go, I'm nearly 100% sure (99.9999%) that has fastcharge enabled.

Don't waste your time. If you tread the reviews, your problem is common with that app. Download Trickster Mod and use that asp.
Also, fast charge isn't going to have any effect if you're plugged into an ac outlet.

Does fast charge via USB even exist for the nexus 7, because so far this seems like some sort of vapourware joke that doesn't exist.
My device is shot, the headphone jack has gone bad, and now regardless of what I do I will always get charging from USB. It won't connect to the PC, and won't power devices from an otg cable, I even made a fast charge usb cable that tricks the device into thinking its an ac power source..... It works with everything but this, so its safe to assume that if indeed there is no fast charge I will take great pleasure in smashing this to bits.
Has to be up there with the first generation Xbox 360 as one of the worst build quality devices ever made.

And even then only if the active USB device (e.g. powered hub) is also designed to not current clamp or fault-open at currents above 500 mA. It takes two to tango.
Even when it does work, it's nowhere near as fast as a 2A AC adapter, btw.
USB 3 can output 900mA

I have a 2A usb car charger, but is I use GPS programs (like waze) , battery drain in too high , and charging current is not enough.
Any Fast Charge supporting kernel could be the solution.

A kernel with fast charge is inapplicable to your situation. You simply need ausb cable that had the d+ and d- pins shorted.

It shouldn't harm it, I think that is just something the manufacturer says because they haven't tested it with any other charger.

there are two types of mobile device chargers, one is for phones, 1 mA, and for tablets 2 mA, so for tablets, the only drawback of using the phone charger is that its gonna be slow to charge up, and if its a tablet charger, for most cases, really doesnt matter what brand.

i still have the original charger(that one the you connect to the wall and to it you need to connect a USB Cable, which i lost) and it says 2.0A so i guess it's ok but when you connect the USB cable to PC, how many amperes going through?

The battery charge controller chips in the N7 control how much current it will attempt to draw.
If the A/C charger is capable of providing a stable output voltage when it delivers that much current to the tablet, then the tablet will get as much as it is demands. If the tablet tries to draw too much current - to the point that the output voltage of the charger droops to much or gets noisy, the charge controller chips in the N7 will cut back on their current demand.
Unless the MicroUSB cable is exceptionally long or exceptionally crappy, or it has connectors that do not make good contact, the cable won't make a bit of difference. The "shorting of the data pins D+/D-" which signals to the N7 that the attached charger is a high capacity charger happens in the AC charger, not the data cable; so, you don't need to worry about that part of things. (This must be the case, otherwise the cable would be useless for data transfers). If - for whatever reason - you have a "charger cable" that does not have D+/D- data pins, then the N7 will charge at least twice as slowly - but it should still be able to charge if the device turned off.
One thing that somebody here on the forum pointed out many months ago is that the micro-USB connector (the part that inserts into the N7) on the Asus OEM cable seems a little bit longer (in the direction of insertion) than many aftermarket microUSB data cables. I suppose that (possibility of not making good contact) could be an area of concern.
But anyway, I don't think you need to be afraid of damage occuring (as long as the connector fits neither too tight or too loose).
good luck
Hi friends,
Being a hardware electronic designer i would bring up below points :-
1. It really does not matter if yoh change your USB cable unless the cable is of too cheap quality to catch up environmental noise & spoil the dc supply
2. Charger (wall mount) does effect the battery if you use improper rated.
3 In general a computer USB can source upto 400mA which is sufficient to charge a mobile phone but a tab would take pretty much amount of time to charge from LC/laptop USB port
4. for a cell phone maximum 800mA should be finee enough for the battery to charge fast. but if u use more rating please ensure its not too much high (assuming cellphone loaded with battery) offers constant R is a myth it can lead to safety issues & wirst cn giv u shock if u end up using it while charging it up with high current source
5.so use any Wall mount charger but dont exceed 800mA for a mobile & 4A for a tab my recommendation 2 b safe
6. USB cable can be anything if it hs shielding m than it is best

To be honest saying 800mah should be the max for a phone is wrong straight away as most phones come with a 1A charger anyway.
Also Li-ions are usually "smart" as in they have control circuits to monitor their charge level. They will NOT draw more power than their circuit is designed for.
Theoretically you could use 50A charger if you want buy as long as the voltage is correct it'll be fine. It will just draw however many amps it needs.
EDIT: your 4th post where you mention battery and food and you can't force it to eat more is incorrect. Amps are not pushed to the phone, only voltage is. The phone will draw however much amps/current it needs.

As an electrician with experience in integrated circuits, I feel compelled to correct points four and five. Whether one uses a 800 mA charger or a 2 amp charger for a phone makes no difference in the rate of charge and will not have any detrimental effect on the battery. Likewise, one could use a 50 amp charger (if such a beast even exists) on this tablet and it would have no different effect than the OEM 2 amp charger.
The rate of charge is controlled by the device itself, within the limits of the power source it is connected to. In other words, if the Nexus 7 is plugged into the stock charger, the maximum current it will draw is 2 amps. If it is plugged into a 10 amp charger, the maximum current that it will draw is also 2 amps. If plugged into a cell phone charger, it will be limited to whatever rate that charger is capable of supporting, generally 750mA to 1 amp.
The most important consideration to avoid damaging the device is output voltage. That being said, one would be hard pressed to find anything that puts out anything other than 5 volts that can physically connect to these devices,

Impact of such thing won't be noticed immediately but it definitely affects reliability of device.
safest would be to ask the manufacturer itself if u cld use for this value of current as u r in a place wer u r nt gttng d chargr & u want to charge ur tab/cell. dey wld guide u bttr.. as dey knw internal circuit.

Again, it seems as though you are disregarding a couple of fundamental electronic principles. The current flowing out of a 2 amp charger and the current flowing out of a 10 amp charger are going to be exactly the same given the same load device. There is no excess current applied to the it. The N7 power adapter isn't on par with something such as a Christie RF80K constant current charger.

The worst could happen is overheating issues & safety issues as most charger dont even have ground connection & if it is high capacity already & if by any chance u gt a call while charging the current flowing could just change in a minute & hamper you & ur battery too so plz hv caution on using charger with proper ratings.

Mine is 2 to 2 and a half hours.
Which battery and/or charger are you using? After coming from the S2 I have noticed a large decrease in charging time with my S4, so this is very surprising to me.

...*facepalm*. You're not using original charger and you're complain that the one you use doens't works so well? Do you know that original charger is pulling 2000mA out, while your usb-port is pulling between 300mA and 500mA (depends if it front or back usb-port and the quality of usb port). Do the math, 2600mAh battery and 300mA / h. Full charge should take: 2600:300 = more than 8.5 hours.
With original charger S4 recharges from 0 to 100 in 1h 49minutes. If you take a solar charger it will charge even slower (like 48 hours for 0-100%).
Next time try to use your brain before complaining.

Your Samsung power brick has the cable physically attached to it? If not, you can just use a longer cable with the Samsung power supply.
The included power supply is 2 Amps, whoever is getting long charging times, make sure you use either the original Samsung power supply, or comparable in amperage supply.
Mine charges in 2 and a half hours.
Mine takes 2 to 2.5 h to charge from 0 to 100 percent. You should only use the new white charger, it's more powerful than the black one from s3, it's output is 2.0A ,old one is only 1.0A. Newer use other chargers as they may mess up your battery or phone.

I have to check the amps but based on google the Nokia Charger is at 1.3 Amps. I need to remind myself to switch the short Samsung to longer Nokia cables.
Is it safe to get a higher Amp charger, the one that the iPad uses to charge my S4? No drawback execpt for a faster charging time right?

the s4 comes with a 2 amp charger. thats 2000ma. it doesnt charge slowly if you use this charger. i personally am going to pop it on this charger when i get home from work and then keep it on my 700ma charger overnight... no reason to waste that powerful output, it will simply waste electricity.
make sure:
1. you use the charger that came with it
2. you use a cable thats as long as (or shorter than) the stock charging cable. longer usb cables tend to charge the phone slower.
also keep in mind usb ports charge any phone slowly. the s4 will charge even slower on them because the battery is oversized compared to most.
