Is 15v --- 3.5a charger ok to charge Asus tf300? - Transformer TF300T Q&A, Help & Troubleshooting

Hi, recently my Asus charger stopped working & unfortunately can't find any of these being sold here in my country, my data cabel is working fine so I was wondering if I can use a laptop charger that has a female usb slot with output of 15v-----3.5a to charge my tab, the original charger had 15v----1.2a.
Any help provided will be welcome.

The only drawback is that the stock charging brick would provide 2 grounds to the cable and then magically the tablet end would have to provide
4 grounds to the table both [usb grounds] and the ground switch and the body of the charger.... Thus the reason it will not charge from a PC.... I would say if it charges it go for the gold... Maybe just dont leave it on for an extended period of time... Hope that helps... Thx lj

I am worried that it might burn the tab, so would appreciate more details regarding what happens with a higher Ampare.

I hear you... I am not electrical genus but on something as sensitive as the electronics are I would stay away from it... I mean worst cast scenario
The battery could melt or even exploit....Ive seen it happen.... It was a car battery but It took off like a rocket...

Thanks for your replies, although some more specific replies regarding chargers voltage and ampares will be more helpfull, I see some 3.1a dual usb chargers being sold over eBay so, still want to know that what difference will higher ampare make to charging and the device it charges.

Well, the voltage should match, but I think amperes are a max. value, so it should not be smaller than that of the original adaptor. But then - I am a software guy and happy to stand corrected.

I guess that the other pins are for audio and other stuff
Try it!
Any Standard Mini USB works
Thanks for sharing but I think we all knew that one already.
And we should call you Amerigo Vespucci, but I`d be happier if I could name you Google or Search sorry
i hardly ever use the HTC cable with any of my HTC phones... to start with , my HTC USB cable is in the mains charger!
Give the guy a break. I remember when I first tried my charger and USB cable that I had with a previous HTC phone and found out it worked. I plugged it in to my Diamond VERY gingerly and winced, hoping not to fry my phone. Hallalujah! I remembered saying to myself. Now I don't have to buy another charger or cable!
I just had that HALLELUJAH moment myself! Thanks

I'm nominating you for funniest avatar awards! At least we'll all be able to take you seriously.
But in regards to your comment, yeah as long as the voltage is the same you're generally pretty safe. The ampage rating don't tend to mean that much as the device will only draw what it needs (in the case that your charger is rated at 1000mAH but your device draws less than that). In the case your charger can't provide enough ampage then I believe the charging process simply takes longer that it would with the 'correct' charger.
If the voltage is different then you can cause serious damage to your device and who knows you could theoretically start a fire.
Rejoice! I've been *****ing all morning about me forgetting the cable at work, and now for the weekend it's low on power. I've been browsing sites trying to figure out what cable i needed to order and i came up short - except for ordering an original which wasn't in stock.
Consider this a 'thanks' and a bump

basicly any charger that gives out 5v with atleast ~500mA is good for you, there are some cheap ones with a miniusb jack at the end, you can get an adapter for pennys that will transform miniusb into microusb. But a samsung charger is a cheap and durable option, tho you can look for an original LG one or HTC one that has a detachable data cable via a standard USB jack. I whould try to find one at any of your local phone retailers, pc shops.

You are lost buddy. The original LG charger of my O1 has an output of 5.1V and 0.7A. You need a higher voltage for a charge the the one of the battery. Id atach a picture of it but some ppl refuse to fix the camera on ICS

charge flow occurs only if there is potential difference... from higher to lower potential... easy electrostatics

Why does my battery go down while my htc is on charge? =/

Is this normal?
all i have is the wifi turned on and whatsapp open.
And why do i keep gettting this message about it not recieving sufficient power or something like that!?
HTC Sensation XE not rooted or anything
Check the running background process close them.
Or set brightnes as low as possible.
Is Your mobile battery condition is good or it die within hour or two without any use?
Mine did that with a cheap charger and the original battery. I got a good charger, anker battery and auto task killer.

Are you charging using the USB port of a computer? This might not supply the phone with sufficient power. A wall charger should do this job better.
Also, if your phone isn't rooted, this might be caused by the battery getting old. Anker has some awesome (and cheap) battery's available on eBay.
as the above posts says, make sure to use a wall charger.
This has happened to me while using 1566Mhz. If i am doing alot of stuff on my phone while charging, my battery would go down. After bringing the MHz a little bit down. its working fine now.
And what cable are you using ? Original ? I had this problem with different cable different from original .

its probably because of the extension cable, try charging with only one cable see how that works out

or with another cable .. I am sure that is from cables that you are using . If you find original cable will be great . If you want to make sure before buy take one original cable from friends or something and try it

That too but the easiest way to figure out is to just try without the extension first. Sometimes different cables do work, though I wouldn't recommend using them

[Q] No Usb cables give enough power to charge the sensation! :@

what is wrong!?!?
The original broke so i tried others from amazon uk and none of them seem to give enough power! im charging with the wall adapter thing not through a usb port.
Anyone got any recommendation?
only UK sites if you do have any recomendations pls and thank you! desperate here!

Something else is wrong here.
A USB cord is just a cord. Aside from it being cut in half there's like literally nothing that can be wrong. It's just copper wire allowing electrons to move freely through it.
If it wasn't transmitting data, then sure. It can be the cord as low quality cords can disrupt digital data flow. But when then I use $1 cords from Monoprice.com and they work just peachy.
But multiple cords not charging? It's just a wire. All it does it carry electricity from the charger to the phone. There is nothing special about the official HTC cord.
Are you sure the charger works okay? Will it charge another device? Are you sure the phone is okay? It could be the battery as well.
Phone chargers are fairly universal, as most smartphones have a USB charger that outputs 1amp. So see if you can find another one from a friend or co-worker and test to see if your phone charges faster with another charger.

Use the standard HTC thing that connects into the sockets, then I recommend using a Samsung USB cable.
I had the same issue and found out my wire was broken :/.
Thanks!
Hope I Helped
Added some screenshots check it out!

OEM Charger

Does anyone know where i can get an identical charge like the one that came with the phone? The reason why is because the one that came with my G3 makes an almost hissing sound during charging and its making me nervous.
does it need to be identical? any 2.1a wall charger with a usb port will do fine. I use my wife's HTC and Nook plugs all the time
Ok and it doesn't damage the battery?
uhm no. rechargeable batteries need a charging circuit in order to not overcharge and blow up (tried it, it does happen lol) consumer electronics have this built in because they don't want their consumers catching fire. As long as you provide it power, it'll charge. The charging circuit will take care of the rest. 2.1a chargers are widely available and will provide a fast charge
Are you sure it's a 2.1a charger? I swear my D850 was 1.8a.
Yeah mine is 1.8a
Look on Amazon, but search for G2 chargers. I don't remember seeing any in the g3 section
Edit: looks like they have one now

You're obviously set on this oem thing, by all means, have at it. But if you want a good fast charger, get a 2.1a

My charger doesn't make a hissing sound while charging (at least not that I have noticed. I haven't stuck my ear up to the charger however). If this is happening to you, I would contact LG or your service provider to see about getting a replacement.

I'm using ones I have around already, one from an HTC phone and another from a samsung tablet. I have a generic one that I also tested (but has another use currently) which also works, I think I got it off Ebay with some cheap batteries for another phone.

Literally any USB charger with a charging capacity of 2 amps or greater. Amperes are not like volts; a power supply can't have "too many" amps for a circuit.
