“A necessary item, and worth getting official one, as older charger for previous pi won't work as it's different voltage. Buy this at same time as pi 3 to save on postage. Also worth getting a case and shorter heat sinks, as pi 3 gets a bit hot. Very speedy delivery, with no problems.”
“There are a few requirements to power the pi, and this plug delivers it well. With a bit of style, the logoed plug delivers it well.
The actual power requires an adapter to plug into an outlet. This plug comes with a few to work in the US, UK, and just about everywhere else. If you're getting a pi, get this power supply.”
“Since I bought this adapter I've been using it for a Raspberry Pi 2 Model B with a Kodi set up. This Pi is never switched off (only for very short periods of time due to updates being installed). Absolutely no problem! Great stuff!!!”
