Best Raspberry Pi Power Supply 2021

The company behind all of your Pi-goodness has released its very-own Power Supply, rated for 5.1V 3.0A of power. You can snag this in either white or black, and there are four different models to pick from, depending on what country you live in.

This power supply from Smraza provides the regulated power your Raspberry Pi 4 needs and the adapter is up to 20% smaller than the competition. If you need to plug things in where space is at a premium, this is the one to buy.

You need two things to get your Raspberry Pi 4 up and running: a power supply and a case. Why not buy everything in a bundle with a fan and heatsinks, too? Save time and save money!

Owners of the Raspberry Pi 3B+ will want to get this power supply from CanaKit, as it's rated for 5V 2.5A. This gives you enough juice to keep your 3B+ up and running for as long as you need. The cable itself measures in at 5 feet long, and has an integrated noise filter near the Micro-USB charging end.

This power supply works with any input voltage from 100 volts to 240, so it's built for traveling. It also works with the Pi Zero and Pi A so you won't have to look elsewhere if you have one of those models. In addition to sporting rating of 5V 2.5A, the OBDOK charging cable measures in at 3.3-feet, which should be more than long enough for what you'll need.

Argon ONE's Pi 4 power supply provides an input voltage ranging from 100V to 240V, and an output of up to 5.25V 3.5A with its USB-C charging port. The cable measures in at 3.3 feet, and was designed to fit perfectly into your Pi 4, regardless of what kind of case you're using.

CanaKit is the primary supplier of many of the best Raspberry Pi kits that you can find in stores. But the company also provides some great accessories including the Pi 4 Power Supply with PiSwitch. The PiSwitch is an add-on that allows you to quickly cut the power to your Raspberry Pi, without just unplugging it from the wall or from the Pi itself.

Nobody likes being limited in where you can place the Raspberry Pi because the power supply cable is too short. That's where a power supply like the one from MakerSpot comes into play thanks to its 5-foot-long AC cable. This Micro-USB power supply is perfect for Raspberry Pi models ranging from the Pi Zero up to the Pi 3B+.

Vilros' Raspberry Pi 4 power supply provides charging speeds up to 5.1V 3A, is designed specifically for the Raspberry Pi 4, and features a 5-foot cable. Plus, Vilros includes a built-in On/Off switch that is located near the charging port end of the cable.
