5V/2.5A Power Supply Micro USB Charger Adapter with On Off Switch for Raspberry Pi 3/2 Model B

The Raspberry Pi 2 and 3 models require the most current; a 5VDC @ 2.5A power supply is recommended. Such power supplies are ubiquitous online, but the fact that the 5VDC line includes a power switch is invaluable. Most kit vendors have included power supplies with on/off buttons for the past year or so. Without the power button, the power socket on the Raspberry Pi board may start to wear out and provide intermittent power; Raspberry Pi runs and then suddenly powers down if you move the cord or Raspberry Pi a couple of inches.5VDC @ 2.5A power supplies are fairly ubiquitous, but don’t estimate the value of the button!! This particular product is well-made and I’ve yet to have problems with the power adaptors to all sorts of different Raspberry Pi models running with different hardware loads via USB and GPIO.

This power supply is very easy to use, with a convenient on/off switch that allows me to easily control power to my Raspberry Pi. It is also very reliable, with a high-quality design that ensures a stable and consistent power supply. The included micro USB cable is of good quality, with a durable design that has held up well over time.

Exactly what I needed for my raspberry pi 3

I sometimes like to take my blackbox over to some synth gear that isn't at my primary desk, and so started hunting for PSU that could supply at least 5v/2400mA. This properly powers the blackbox, however the 60hz hum from this device is atrocious and makes it unsuitable if you're going to use it to power USB music devices like the Dreadbox Nymphes or the aforementioned 1010 Blackbox. It'll do in a pinch but you won't want to keep any samples from those sessions.This PSU feels quite flimsy and cheap, but I would have no issues using it for Raspberry Pi projects.

The added bonus of a power off switch on the adapter made it better than the original that it replaced. Was the right adapter to replace the Pi 2's adapter when it went bad. I plugged this adapter in and my Pi 2 started up without an issue.

Arrived promptly and works great!!

Unit has a nice displayy showing batter charge. The only thing I would recommend is an instruction sheet. Takes a while to figure out how to insert the different cells.

I used this to power a Raspberry Pi 3 Model B to run OctoPrint for my 3d printer, and while it worked without issue for the first few days, it recently started warning me of under voltage despite me not connecting anything else to the Pi other than a small 40mm fan days before it started warning me, and I ensured the printer was not getting backpowered by the Pi. Design is good with the on/off switch on the cable and reasonable length, but apparently it's not the correct power that's advertised as the only additional power my Pi is using other than powering itself is a small 40mm fan, which shouldn't draw so much power that it gives me a warning. Disappointing since the whole reason I bought this was to avoid undervoltage issues since I didn't have any spare power cables powerful enough to constantly run a Pi.
