So if you use this charger with the adapter from that site and set a higer voltage you might fry the usb from your tablet. Sorry to disapoint you but better now than later with a broken tablet.

Thanks Pal. So no any chance for a charger or dock with UBS to not only charge but also for host mouse or keyboard?

I use the short cable with mini and Type-A/female connectors provided with the A700 . This accessory cable will provide you with a standard USB connection.

Check out this link which has some good connector info...

http://www.cablestogo.com/resources/usb.asp

Using a wireless mouse with the wireless transceiver/USB interface, at times referred to as a "dongle", inserted into the type-A female USB connector of the short cable. Plugging the mini connector of the short USB cable into the mini female USB connector located at the bottom of the A700. I switched the mouse on and moved it around. An arrow type cursor appears synched to my hand's motion. It would have been more convenient if the small interface cable had a right-angle mini connector at the end, which I found later to be available from many vendors on the web. Anyway, my mouse works fine.

Then I connected a cheap($15.99) BT(BlueTooth) Logitech wireless keyboard for text editing and writing JAVA programs with so many errors that I'm glad I connected the USB mouse & BT keyboard...

OK, thanks for info.

I think I have to explain - I know I can use the cable provided by Acer but then there will be no charging.

I have Notion Ink Adam and there I can plug a charger (not USB), then I have 3 x USB (1 mini and 2 normal ones) with a Host in one USB. I do not expect so many connections but at least a possibility to use A701 with a wireless mouse/keyboard and be able to charge it in the same time. So therefore I thought to find a divider - a cable with two females and one male connection. Does anybody know if such a thing exist?

I know - when I charge this tab I have many hours of work but would like such ability. Even some small Android stuff like e.g. Rikomagic MK802 has some opportunities (I use it with my TV set).

Best regards/Pozdrowienia

Acer a700 tablet charging adapter, oddly, is a 12v output mini adapter. The mini use is the standard except with 'L' shape. Unfortunately, if that crap on you, you will almost completely totally screw. Fortunately, if you still under 1 year warrantee, ACER may send you replacement within 5 business day depends on where you located. Of all the same type USB chargers out there are 5v standard. My emergency to be able to use the device is look for a Similar Output Voltage (12v)' connect it to mini usb with some cut and tape the wire. This is the only option until Acer adapter arrive. Funny thing is, all the retailers I shop around with Acer a700 tablet on shelve, but none carry the device accessories. It's a bad marketing strategy.

i have the A501 and we have all the same prob, 700 is the clone with HD screen but same flaws...

it seems Acer wants to play Apple with its crappy tuned mini usb connector, but acer is not apple, and quality
and materials are not the same...the A200 is simplier, standard usb, standard charger, standard charge jack connector,
whats the problem with top end tablet as 510 and 700?
uh yeah, if one day my tablet fries or dies, acer will never see me again, and i will go to asus...
perhaps standard connector is intelligence proof , tuned connector is borderline logic....

I have been awaiting shipment of a new charger and have been using the USB 3.0 port, seems to charge about 50% over an 8 hour shift at work using the supplied USB cable.

Question
So has anyone found a suitable car charger for the A700 yet?

I can't seem to find a car charger that puts out the correct 12V 18W 1.5A that the A700 requires to charge.

I currently use the wall charger + a power inverter in my car, but I'd like to stop that if possible.

It's the A510 that is most like the A700 not the A500. Though the A500 does share some similarities it's not the closest match.

When I look for any type of charger, I make sure that the output voltage is correct and the amperage requirements are correct. Looking at the A700's charger, the manufacturer managed to squeeze a lot of info onto it. Amperage is what I always try to find. That is the total amount of current it can handle and deliver to the device connected to it. The A700's charger can handle 1.5 amps. So, the A700 sucks up a quantity of 1.5 amperes of electrons in order for the battery to fill up to it's capacity. That is the load the tablet's battery presents to the charger. Make sure that the charger bought for the A700/A510 can handle at least 1.5 amperes or the wall wart will be OVERLOADED. This is where the charger begins to overheat, smoking warning signals may start coming from the plug and your're asked for a donation for the local voluteer fire department. Besides the voltage which is 12 volts dc, load current requirement is the most important value I make sure is correct for saftey's sake. It is alright to get a charger that has a higher amperage rating but the voltage must be the same, 12vdc for the A700. It just means the charger can handle a larger load.

The only adapter I could find was the original Acer product, mainly because of the unique USB dual purpose connector interface. There is a little diagram of the pinout for the plug on the charger. Using a magnifing glass, I could barely make out the pins the +/-12vdc are attached. Pin P1 is +12vdc and pin P12 is -12vdc. It looks almost beyond a humans capabilities to make or solder together a short plug interface conversion cable in order to use other 12vdc/1.5 A chargers.

I've read in the forums some uncertainty about the proper specs for a replacement charger for the A700, that's why I wrote this post. Maybe , this will help clearup some of the confusion and not add to it. I've also noted a lot of chatter about using a USB cable with the micro USB plug to charge the A700 tablet. Apparently, USB charging can be acheived but it is very slow ( 24 hours or more ) and the amber/white power LED does not indicate the tablet is charging or has finished charging.

If anyone has more info about the A700 charger please reply or post....

Thanks All...

Hi,
The problem I have is that over the last year or so I have gone through two of the acer chargers for the a700, or to be more precise my son has. The first one that came with the tablet was an import with the tablet, so acer weren't keen to help in any way. The second one which I bought my son to take to Afghanistan with him has also packed up, possibly due to heat, dust or general misuse! I wont know for sure until he gets home. At 30 a pop, when available this is going to get expensive. My questions are as follows 1. does the wall charger output have only two cables coming from it, a 12v+ and - or if not do you know how it is wired. 2. I have a 12v 4a adapter from a monitor, would it be possible to cut the cable from the broken acer adapter and solder it to the 12v 4a adapter to use as a charger for the a700. Thanks for any replies in advance.

FWIW, I can charge my A700 by plugging it into the USB 3.0 port on my PC. It doesn't charge as fast as the included AC charger, but it does charge...
