“As Raspberry Pi cases do not have space for fans or large heat sinks, it is with piece of mind that a regulated voltage supply specificaly for the Pi be used.”
“Nothing to complain about here - good price, good quality product, and for the Raspberry Pi especially, it is important to have confidence that the power supply is sufficient and will not lead to reboots and potential corruption of the SD card, etc. Happy with this and would buy again if I guy another Pi in future.”
“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.”
