You might be tempted to use an old phone charger (or even a new one!) to power your Raspberry Pi 4 but you really shouldn't. These little computers need a steady and clean source of power at 5 volts and 3 amps, which means any old wall plug that has support for fast charging can't provide. The good news is that a dedicated power supply for your Raspberry Pi is nice and easy on the wallet.
CanaKit makes some of the most popular parts for the Raspberry Pi and this power supply is designed specifically for version 4. It's a perfect choice if you just need a way to keep things powered up.
This power supply from IBERLS 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!
It's the reliable power supply from CanaKit with an inline switch for those times you need one. No more climbing under the table or bench to unplug the cord — your knees will thank you one day.
A power supply with an inline switch that doesn't have any glowing LEDs is a beautiful thing if you sleep where you tinker. The tiniest red light can be unbearable sometimes, and this power supply is the fix.
NorthPrada's power supply is filtered to cut out the 60Hz harmonic noise that can happen when you plug anything into your wall socket. If you are building any sort of audio solution with your Raspberry Pi, grab this one.
