Usb power adapter comparable with any device?
A lot of device power adapters just have a usb plug on it and you use any microusb cable to charge the device.
Can you damage a device by using an adapter that is under powered for it? Or will it just be slow.
And Can you damage a device by using an adapter that is over powered for it? Will it charge faster? Will it just draw what it needs and charge the same as usual? Or will it fry?
The specific situation I'm wondering about is this. As long as I don't mind only charging one device at a time, can I take only the the most powerful usb power adapter (playbook adapter is 1.8 A output) and use it to charge my phone (came with a 0.7A one) my wife's phone (came with a 0.4A one) and a sansa clip mp3 player that justcame with the usb cable.
All thoughts appreciated.
