Raspberry Pi B, B+ and 2 used 5V 2A power supply, however they now suggest 2.5A 5V for the Raspberry Pi 3, see table below:
Raspberry Pi Model A+ 700mA
Raspberry Pi Model B+ 1.8A
Raspberry Pi 2 Model B 1.8A
Raspberry Pi 3 Model B 2.5A
I suspect you might be able to still use a 5V 2A power supply.
Which power charger does the raspberry pi 3 need?
You're welcome
The first package just arrived and it is awesome, thank you klintay!
Green trust.
