Power supply for Raspberry Pi 2 Model B ?

Former Member over 10 years ago

Hi everyone !

I'm new, and going to order new Raspberry Pi 2 for my teaching jobs. I'm a teacher and interested in learning dev kit.

Seller delivered a kit without power supply, and I dont know sure that my Nokia adapter (5 V/ 1.2A) is enough for my new Raspberry Pi 2 board ?

Thank you !

ps: sorry about my English

That graph is correct, unless you forget to add any current used by USB devices not powered by external powered hub. Thanks Paul Clem

You did not specify the connector, but if it is micro usb you are good to go. I use a RavPower supply with 4 usb (1 ampere). Only at start up do I see a little artefact in upper right corner briefly.
Hope this helps,
Clem

I've used a Micro-USB nokia charger for a few years. Originally on a Model B and then a B+. No issues.
