## Description

Package Include: 1x Micro USB Power Supply

Review: Does the job for Raspberry Pi 3 Model B+ - I was using a Raspberry Pi Model 3 B+ as a printer server. No Raspberry pi's come with a power supply because apparently everyone has old spare mobile phone chargers. However this fails to take into account most old chargers are 1A or less, and the rpi constantly complains about having low voltage. This power supply fixed the problem immediately and also has a handy on/off switch which saves the power port (although you'd be better shutting down the rpi properly rather than just cutting the power to avoid SD card corruption). I'm happy with this power supply. Decent price, a micro USB connector (becoming more rare now and no-one wants to mess about with Usb‐C to micro USB adaptors) and a UK plug, despite the photo on desertcart and the illustration on the box.
Review: Simple and Works - Bought to replace a Pi 3b PSU's frayed cable. I like the power switch as it made quickly restarting a stuck PI easy. Seems like it'll do the job for a while so no complaints so far as have been using now for a few months

### ⭐⭐⭐⭐ Good third-party power supply

Currently using this with an original Raspberry Pi B+, works fine, no issues. The in-line power switch is appreciated.
