It isn`t possible, I don`t think. The thing you are charging sets the maximum amount of current it will accept, not the charger. And this determines the charge time. A computer supplies a maximum of five amps to its USB connections but should not charge your phone/tablet etc any faster.

I strongly recommend sticking to genuine, branded chargers from a reputable supplier. Cheap, generic Chinese ones can damage your devices and have a habit of catching fire.

Incorrect.

All USB ports supply 5V, with the exception of the quickcharge ports now being seen that can supply 6V, 9V (possibly more).

The minimum specification for current for USB 1.0 is 500mA (0.5A), which in my experience almost all computer ports are, which means devices generally charge really slowly from a PC, unless it has higher rated ports - often labelled as charging / power ports.

You're correct however that more Amps, generally means faster charging, and the ceiling current is indeed set by the device.

Yes, you`re right of course. I`ve never seen charging ports or quickcharge ports and of course computer ports will generally charge more slowly than a normal power supply which is rated at 2amps say.

Yes, well I got one thing right :)

I was looking for something that is potentially going to catch fire, damage equipment and maybe electrocute the user. That's the mother in law's christmas gift sorted.
