    it should tell you on the tablet or its instructions

    If it's an Asus it could be as high as 17v. A standard usb only provides 5v.

    Let us know the make/model.

    if its micro USB it should be 5V as normal.

    it may well be your current that is just not enough. look up the specs in the manual. and post make model as suggested above.

    not all tablets are the same, mine doesn't charge via USB as it needs 3A so has a separate power supply (a Toshiba).

    What ?
    It's a tablet . All of my tablets are 5v but with different connectors , some microUSB and some different sized round pins .

    That goes for mobile phones too , different connectors but nearly all are 5v.
    DONT CONNECT A TABLET TO 17v ...............................you wont be able to use it again !

    It won't be voltage it will be ampage. 2amp minimum.

    ^^ This ^^ anything with a USB connector on it only sees 5V??

    However, the bigger the battery the bigger the current needed to charge it normally.

    My iphone has a 5w charger, my ipad a 10w etc

    Does that mean you can stick a 13amp plug onto the end of a microUSB cable and charge up your tablet from the mains ???

    For God sake folks ................dont try try that at home .

    Tablet will only draw what it needs. Most big smart phones and tablets are 2amp chargers plugged into the mains. If you are going to be a drama queen might I suggest a job on stage?

    looks like your tablet charging connector is broken or deeply discharge tablet battery.

    Actually the new USB power delivery spec does allow for other voltages with 12V and 20V being standardised as well as 5V as that was a better option than increasing the current further so particularly recent devices could in theory be 12V/20V while also being USB. I don't think it's very common in practice at the moment but it wouldn't surprise me if we saw 12V USB tablets in the next couple of years.

    I gather that some of Samsung's tablet do nasty proprietary stuff though. Looking at the manual for the Galaxy Tab S 8.4 it says to use a 'Samsung Approved Charger' but I can't seem to find the list of them. No surprise there on the customer service front from Samsung.

    Your best bet is to either grab a charger that explicitly supports Samsung's nasty proprietary stuff or you could try a so-called 'charging cable' that gimmicks the data lines within the cable to make the charger think a USB compliant device is connected.
