Charging the Tf300 (only charges through original charger?)

I've been playing with my Tf300 for a week now.
This weekend I wasn't home and wanted to charge it. It didn't work.
I tried four different chargers including an iPad one, two Griffins, one belkin with no luck.
I have the original cable and two generic ones I bought from Amazon.
All cables work with the original charger... But NONE (even the original one) works with other chargers.
Any ideas if this is wrong?
I would hate to buy a new charger instead of only taking with me any cable with any of the other chargers I own.
Anyone with the same experience? Why is only the original charger working?

Noticed the same thing.

Noticed that with the car chargers as well

Forgot to mention that I also tried with two car chargers (Kensington and Griffin) with no luck

I'm no electronics expert but I noticed that on my Phone charger (Xperia Mini Pro) it says 850mA, but on the tablet's charger it says 2A. I think that other chargers dont pack enough punch to charge the tablet.

I used an iPad charger with no luck... The car chargers I used all have worked with my iPad.
Anyway, it seems that it's not only mine then.
Now I wonder if there's a work around for this... Besides buying a new original charger

Damn chargers are $30

you can charge your device with a "not compatible" charger if the tablet is turned off. for me it worked with the charger of my galaxy nexus but it charges really slow

I read other articles about charging TF300T. For normal charging the charger must have output at least 11v (12v is usual) and 1.5A (18Watts). Its own charger has 15v 1.2A (18Watts).
iPad charger out only 5v 2.1A. TF300 could be charged with iPad charger but the screen must be off (and it will be very slow, overnight for an 1-2 hr normal charge). So check your charger output voltage and amperage. Thank you.

But doesn't have the charger of the TF300T 5V/2A?
I noticed it on my car charger, but it only has 5V/1A. So the tablet does nothing, even when it is turned off.
It only charges with the original charger.
But I assume other chargers with at least 2A should work without any problems, right?

The tf300 charger is not 5V, its either 12V or 15 V (can't remember which). This is why you see nothing. if the only difference was the current (1A Vs 2A) You would still get a charging notification, it would just take longer. The difference in voltage means It should not be able to charge at all off of a normal usb connection.

Saw that guy on ebay for $13. Think it would work?

the tablet gets charged on a normal usb port it just doesnt tell you its being charged and it take quite a while to fully charge up

I haven't seen it charge any when i've plugged it in to my computer via usb. but it could be that I don't have the patience to wait long enough.

yes, but it will be slower than with the charger it came with. that charger only has a 1.2A output as compared to the 2A of the stock charger.

Everywhere I read, people have said that it does not trickle charge at all via usb. Can someone confirm this?

Okay, I can confirm that the TF300T charges at 15V/1.2A.
Both, the tablet and the dock uses 15V. None uses 5V.
I was confused because it's USB. For this purpose it can transform to 5V/2A. But this is not for the tablet.
So I think it's not possible to charge it on a normal USB port.

Has anyone tried using a USB extension cable? I tried one on my Tf300 and it wouldn't charge, no matter what the table arrangement was. It would only charge off its own charger and with only its own USB cable in the USB charger.

At a guess, i'd expect it's because the ASUS charger outputs 15V so the charger or cable will be wired differently to a normal USB lead in order to prevent blowing normal USB devices if you connected them.

USB 3
I can't remember where, but I read that this needs to use USB3 cable. Sorry if this is not the case.

Can I charge NExus 7 with a 5V 1A charger ?

Bought my Nexus in the US this summer, really enjoy this little beast.
I have a question regarding charging. The provided charger is a 5V- 2A charger but a US one. I have at home a HTC one X charger which delivers 5V - 1A. Can I use this charger ? What is the difference between 1A & 2A ?
Thx, Yves

I don't see how less amps would hurt it. It may not register a charge, or charge very slowly. I would wait for another opinion.

2A will charge faster than the 1A charger. That's the only difference.

OK, thank you

On the flip side, can I use my N7 charger to charge my mobile (SG2)?
My SG2 charger is set for 0.7A, while the N7 charger is set at 2A.

Mine charges with the USB cable i use to transfer files, which is about 500mA. Works but slow.

checking around the net, that's what it say.
the USB port have a maximum of 500mA i believe. And i did noticed it tend to charge more slowly. While the provided Asus charger with USB port on it, it have 2000mA (or 2A). So i guess the Nexus 7 is made to be able to support up to 2000mA, while it will charge more slowly when connected to a computer's USB port.
I took out my PSP and its charger recently, and this charger is also 5V, 2000mA, except it's a round tip made to fit the PSP charging port.
I do have another 2000mA charger, it also have a round tip, luckily it fit on my Ainol Elf II tablet. I got this charger/power supply when i bought my HDMI switcher, it work without it, so it was sitting there for all this time, unused.
i'm gonna try charging it with the provided Asus charger now.

Yes. Your phone will not charge at the same rate as the N7, however.

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.

I use my GNex charger with no problems.
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.

Can I use regular 2A charger with N6p?

There are no many adapters on the market and I couldn't find original huawei adapter. Can I use a regular adapter (samsung 2A for example) with my Nexus?
Sent from my Nexus 6P using xda premium

Yes, but you must use a certified cable. Check Benson Leung's reviews on Amazon to find a good one or use the cable provided in the box.
However you can buy original charger from Google Store or a valid alternative from Amazon like this:

If I understand correctly some articles USB A chargers doesn't support type-c power profile, so the phone will charge at a constant rate without lowering amperage to be gentle with the battery. Furthermore the quick charge is a very useful feature, so I suggest you to buy a compatible charger.

Absolutely. Just be aware that charging of the Nexus 6P/5X is limited to 1.5A over a proper USB Type-A to USB Type-C cable. With a USB Type-C to USB Type-C cable and a Type-C charger, it charges at up to 3A (as it does with the official charger).
So if you're worried about speed of charging, you may want to get yourself a new USB Type-C charger, as a Type-A charger will take about twice as long! (a 3A USB Type-C charger takes about 90 minutes) Personally, I just have a USB Type-A charger by my bed, since it will definitely finish charging while I sleep. Then I keep the original charger in my work bag, in case I need to quickly recharge during the day!

I don't know if that's the case, but if it is, I'm not sure it matters. With the USB Type-C charger it's drawing 3A and then lowers as the battery gets full, but I don't know how low it gets. Whereas a USB Type-A charger will be drawing 1.5A maximum, so it may not even need to lower.

Any good USB type A charger that you can recommend?
I Have a good opinion about Samsung adaptive charger that my wife uses with her note edge.
Sent from my Nexus 6P using xda premium

I am partial to Anker brand chargers. I would suggest the PowerPort 2 (as I own a couple), it is capable of charging two devices at up to 2.4A each (while the Nexus 6P can only draw 1.5A, iPads can draw the full 2.4A because of their proprietary tech). But as you can see on the Anker website, they have a ton of different options!

compatible charger

OK.... so i wanna know is it bad if i charge this phone with samsung adaptive charger ? and what about AUKEY USB-C Car Charger with 5V/3A USB C & Quick Charge 3.0?
My another problem is when i use oem charger my phone getting really hot like the back panel 110 degrees till almost 90% and then start cooling down, but i dont have this problem with samsung charger and my phone still charge pretty quick.
is anyone has the same situation?

The phone uses USB-C power delivery for charge spec. QC3 chargers don't work at all on my PH-1, seriously charges at .5amps. You're fine to use the Samsung charger or any other adaptive charger like Ankar power port chargers, they work fine.
Not sure about your phone getting hot using the stock charger though, mine doesn't do that.

So the phone will charge with an old USB Type-A charger and a Type-A to Type-C cable? What if it's not a QC3 charger like my Anker PowerDrive 2? I've read that some peoples phones charge slower than it uses power when using older chargers, but then some people say they charge ok, slower, but not that slow.

Yeah the power port chargers work just fine. Just not QC3 chargers, in my experience.
