CanaKit 3.5A Raspberry Pi 4 Power Supply (USB-C)

I used to have a lot of trouble getting my Pi4 to boot because of low voltage problems. I tried a generic 34w power supply with a Power Delivery (e-marked) cable and it didnt help; apparently the pi4 doesnt comply with the official usb C spec. I finally decided to get a power supply that was designed for the Pi4 and am happy to report that Im no longer getting those warnings and my Pi boots up fine every time now.

I purchased this power supply for my own use on USA 120 Volt, 60 Hz power. This power supply has a cord with a USB-C connector which plugs directly into the power input of a Raspberry Pi 4 or Nvidia Jetson development board. The output current is rated up to 3.5 Amps, which should be more than needed for most situations unless a HAT requiring a lot of current is attached to the board’s expansion header. This power brick is sealed, so short of destructive disassembly the quality of the internal components can’t be examined. What can be said is that the brand name is well known, so there is a stake in assuring quality of construction. The blades that plug into the wall outlet are offset towards one edge, thus in most cases this power supply and another cord can be plugged into a standard duplex wall outlet at the same time.

I was more than a bit surprised most (all so far) of my type C chargers dont supply enough voltage for the Pi 4. This did and so far I havent had any issues with Cana products.

Does what it says it will do

This has been working well so far after a few months. No voltage issues so far.

This Raspberry Pi Class C charger works as described. It is value for money.

Works fine. Been running for weeks without any issue.

Works perfectly for my RPi 4.

Whats there to say, It powers up the Pi...

This power supply is high-quality, well-made and a good value considering you get the full promised power output. The cord is UL Listed, and feels like a good cord thickness and length. I previously was using a cell phone USB power supply and would occasionally receive under power error messages. I havent received any since switching to this supply. The only drawback is that it is a full sized plug as opposed to a slim one, so it might take up more space at your power outlet.
