I want to get a raspberry pi a+. I am trying to figure out how I can power it. I will use it with a USB Bluetooth WiFi Combo Adapter. The power consumption of the combo adapter is less than 1.5W.
As I understand things, it uses the mini usb socket as a power input. This is the same as the socket on my phone.
I am reluctant to buy a power supply specifically for the pi because so far I have boxes full of power supplies for various things and I'd rather not get another one to add to pile.
Can I use a USB A to micro B cable, and plug that into a computer, a phone charger or other usb power source to power the pi a+? Is there any danger of damaging it if I try to power it using any of those sources
The type of cable I'm talking about is like the one in the following picture:
