Raspberry Pi 3 Charger, 5V 3000mA Power Supply 3A Micro USB Charger for Raspberry Pi 3 Model B /3 B/Pi 2 Model B/B Plus, Banana pi

If you have a raspberry pi that uses the Micro USB power socket, then this is a PSU that can supply the required current without the pi warning about power or crashing. Cheap enough and worked fine.

I was getting under voltage icons constantly in RetroPie, on Raspberry Pi 3B in my NESPi case. Turns out the low-quality, thin wire that runs from the NESPi's power input to the power input on the Raspberry Pi causes just enough dilution of power to cause under-voltage errors when powering the PI from a USB cable of under 2 Amps. Apart from the annoying, nagging warning, I was also experiencing some slow down and jitter in intensive games. Got this 3A adapter to replace my original and nest presto! All power problems are gone! This is also handy as I bought a small fan for the case, which it probably would have struggled with, given the existing problems.

Great psu with good thourough-put for voltage and good stability and compatibility, good cable length too

As has been said already, the output voltage at low load exceeds the Raspberry Pi specification, although the chance of damage is low. It runs a Pi3B with no complaint. I have run two supplies for a couple of hours each on a full (3A, resistive) dummy load: there was no problem during that time. I chose this supply partly because it has no switch: switches increase the supply impedance, so can give "brown-out" errors at the Pi.

Works as intended, RPi no longer complaining about low voltage. Nice and small too, fits with other bulky plugs very well.

I've been using this charger for 8-10 months. I have two of them, both for a raspberry pi 3B+, one for an Octoprint setup and another for Retropie. They work pefectly and I haven't had any issues. I'll be getting more of these in the future when I start other pi projects.

My original power solution 5.1v/2.5a fell a bit short providing power to my RPi3B+. This provides enough power, for the Pi and the stuff I've got plugged in to the USB ports. And it seems stable too, I've not yet seen the little yellow lightning icon (low power).

Works as described
