are mobile chargers useable on tablets ?
 

I have a Samsung Galaxy S2 , so have a mains charger and a cig lighter car charger , but will they work on my new Galaxy Tab 3 ?

Phone (mains) charger is 5v 0.7amp , and tablet (mains usb adapter) is 5v 2.0amp. The car charger is 5v 0.5amp. Will it work , but just take longer to charge ? Would I HAVE to get a new car charger ?

It will work all be it very slowly. You may well find it says it's not charging but it should do. Helps to turn it off or minimise the processor load to speed up charging.

Even on my phone if im using blutooth (music) and satnav at the same time it just keeps the charge steady , as in it doesn't drain , but it doesn't exactly charge it any more ! I'll see how it goes then maybe buy a new one.

It'll take longer to charger and wear out your phone charger quicker

Yeah , I think I'm asking a bit much from it.
