Charging 2 Mobile Devices from 1 Charger

[Thumper-BillyB]

I would like to charge my śmart phone and a tablet from a single charger. The specs are as follows;

Charger = 5.2 v and 2.0 amps
Smart phone battery = 3.7 volts and 3300 mah
Tablet battery = 3.7 volts and 4000 mah

So using a Y cable, will this recharge both devices with any level of efficiency? Will the 2.0 amp tablet charger be adequate to do both at once?

Thanks in advance

Chances are you will damage the charger (and possibly the devices). Each device could easily want 2.0 amps (depends on the device).

Also, sometimes there is a "charging protocol" between the charger and the device, and connecting in parallel could mess that up. There are a variety of signalling methods (could be proprietary or standards based) used to determine charger capacity.

There is always a chance it will work, but it could just as easily burst into flames.

Your best bet is two chargers sharing a wall socket :)

There are 2 (and more) USB port chargers available.
