I've been looking for a couple wall outlets that have the standard two 110V plugs and 2 USB ports and there are quite a few out there. The problem is I haven't found any that can charge the way the default charger that comes with the tablet charges. 5V with a USB 2.0 cable and 12V with a USB 3.0cable. Are there any out there that can do this? This would save me alot of plug space in the bedroom if so, one plug for the tablet and one for my phone.
Thanks

Hi y'all,
I'm looking to buy some new chargers (wall charger, car charger) for my HD2 (not that this should matter, I guess it's something that applies for a lot of devices) but can't figure out which combinations of chargers & cables will really charge at 1A.
The combination of an iPod USB charger with a micro USB cable from my local store resulted in 'USB connected', and hence maxed out at 500mA. Recently also used a 1.2A car charger with a micro USB cable (both from dealextreme, being cheap =) ), and once again I got the dreaded 'USB connected'.
What do I have to buy or do in order to make my phone understand that it's not charging through USB (well, in a way of speaking) but through a wall charger?
Muchos thanks!
Edit: did some more research. Just short circuited the 2 center pins of my car charger, and now it's recognized as AC, whoo! I suppose this applies to all chargers, hence, question solved!
Can the transformer charge through a usb cable connected to a computer? Every time I try it won't do it (I'm plugging it into a usb 2.0). I can only charge by using the AC adapter. Anyone see this?
Only of the screen is off or the power is off, and even then it's very very very very slow.
So for all intents and purposes, no.
Why not charge it through power adapter?
For mobility, I ordered this:
charger cable extension (to make the USB charging cable longer)
USB 3.0 A male - A Female Extension Cable (10 feet)
Not really a asus accessory but for myself I ordered this mini surge protector with dual USB ports... being in south, we get a lot of lightening storms so this is a must (for bed-side and you don't want to buy huge surge protector). Plug into wall next to a PC or something:
Belkin mini surge protector dual USB charger
Hope that helps!

Let us know if that extender cable works for data and/or charging. Thanks!
it charges in 1 of 2 ways
USB [email protected]=10watts
Wall [email protected]=18watts
so, as you can see, the wall is the much more effective choice.

I have one of those Belkin units, they're very nice. But I can't find the specs showing the output on the USB ports. Is 15V @ 1.2amps a standard and this supports it? A bit ignorant about such things...

Charging through USB 3.0 from expansion card?
Has anyone try charging TF (& Dock) through USB 3.0 available from expansion card?
I have and it doesn't work but several people have tried and it does. Seems to be hit and miss as to whether it works or not. Even same usb 3 cables have different results.

There could be many things at fault here. First would be the usb 3 port and whether its on the mobo or card, and then i would put fault on the drivers (or not having installed them)
Why don't people want to use the charger that came with the unit? I can't imaging not using a unit with a least the same output (V & A) as the factory unit. Also, does anyone know if the pinouts track with what is coming out of a USB 2.0. It would not be too good to put power into the wrong pins.

No I mean to say that some people, including me, are trying to extend the charging cable by inserting a usb 3 extension cable between the mains charger and the tf.
It works for some, not for others
As the cable is too short, I attached an extension cable.
However, now it does not charge. If i connect the short cable that came with the Transformer, it charges fine. Any suggestion?
The TF101 "short cable" as you call it, is a USB3 cable, what has +5 pins inside. One of these pins control the 15V charging (the tablet takes 15V from the charger instead of the usual 5V USB), if it can not send the signal through, it won't charge. You need a USB3 extension cable what's pretty expensive though.
Get this one or a similar one. As you can see, 2 reviewers vouch that this cable works.

I can vouch for it, too.
Got on of this USB 3 cable while at HK and work without any problem.
Thank you guys. Will be purchasing one. I am guessing Belkin F7C008QAF Conserve Valet USB Charging Station - Energy Saving wont be working with this :/
That is correct, because the transformer looks for termination of one of the usb 3 pins, if you plug it into a usb 2.0 or lower extension/hub it just wont work. You must have a usb 3 extension/hub, or, there are many DIY chargers that are probably cheaper than a usb 3 extension cable and definately cheaper than a usb 3 hub.
Even a usb 3.0 hub or charging station will not charge it. Usb does not provide the voltage required. Only the outlet adapter will work

Are you saying that my cigarette outlet will be the only thing that charges this?
It won't charge it all with anything unless turned off. Guess I need to make a hybrid cable

hi,
i have just bought the S4, the only problem is the white mains power charger cable is too short for me.
Can anyone recommend an extended mains power charger that is compatible with the S4 i9505?
Thanks
Any micro usb will be fine just keep in mind the longer the cable the slower it will charge the phone. I personally bought a power strip to add more distance ... but I also have a 10ft usb cable that charges my phone very slowly
Don't listen to anyone that says to get a usb extension cable.
to answer you'r question, you can't get a longer cable for the s4, at this time.
the usb cable and charger are "special" you have to use what came in the box to be charging the phone at ~1.5 amps, if you so much as just use a different microUSB cable, the current will go down to ~0.75 amps (effectively doubling the required charging time). same goes for the wall adapter.
When I got my Asus TF700T I got one power plug and 2 USB to tablet/dock plugs. The first thing I was VERY disappointed about is how short the USB cord was. When in my bed I could not plug it in I had to use it off battery only due to the shortness of the USB cable.
I went out and bought a USB male to USB female cord to use as an extension cord and low and behold it would not charge both the dock and the tablet when plugged into the Asus supplied AC adapter. I am assuming the extra length might have knocked down the power from the AC adapter just enough to not charge both devices.
What you need -
1) Original USB to Tablet Asus TF700T cord
2) Any length Male to female extension cable. I bought a 7 foot.
3) A 110-220 to 12 volt 2 amp power jack(car jack) converter. This is the one I bought any should work with the same specs. http://www.ebay.com/itm/130962356608?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
This is a very easy "hardware hack" to do.
1) Pull off the 12 volt car jack at the end of the converter it will leave you with a + and a - cable coming from the power brick.
2) Simply strip off the male side of the USB extension cable disregard the 2 data cables and just use the + and - power cables. Solder/clamp/or connect and cover each connection with electrical tape.
3) Plug the USB cable into the female end of the extension cable that is connected now to the converter.
3) Plug in your dock and tablet and watch both charge at a decent rate. This gave me enough cable length to plug it in behind my bed and be able to have it plugged in and on my lap.
Also doing it this way allows you to not have to hack up your devices USB cable and you can still take it out of the female end for any syncing or traveling purposes.
Hopefully this helps someone else who has issues with how short the charge cable is for this tablet.
A USB extension cable does work, but you specifically need a USB 3.0 cable. 2.0 doesn't allow enough voltage to travel through.
All I did was buy a lamp extension cord for .99, plug the wall wart into it and plug it in the wall. Now it's close enough to the bed or anywhere else I might be.

Or you could do that. :laugh:
Still the best solution, I quite agree.

...because the charger uses some of the USB 3 wires to detect the tablet and enable 15 V - with a USB 2 cable it detects only a generic USB device and charges it with the standard 5 V.
