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

good products

I purchased this because I have a Raspberry Pi 4 coming and I don’t have power adapter that has a USB type C connection. I notice that this adapter has an output current of 3.5A available vs the 2.5A used by Raspberry Pi 3+. Its output voltage is biased up slightly from 5V to 5.1V, probably to allow for cable and connector losses. I am glad to see that this has the UL mark and the box within a box double insulation mark. I am pleased with this purchase. One thing I wish it had was a switch to turn it on and off. I hate unplugging the connector to do that.

I purchased two Raspberry Pi 4s a while back, along with 18W chargers. I would often get the lighting bolt indicator for low power... Many chargers will negotiate higher power for charging, but will max out at 2A without this negotiation.

voltages are spot on under load. no drop-outs or low power warnings with a small handful of USB devices plugged into a RPi4. One of the better RPi power supplies Ive used.

SSDs connected via USB 3.0 sometimes draw more amps than the stock 5V3A power supply is capable of delivering resulting in the low power “lightning bolt” icon flashing on the screen. This power supply is rated at 5.1V3.5A to handle the extra draw.

Great

Works as expected.

Serves a simple purpose and does it well.

Doesn’t get too hot and works great.

had a problem from my new pi 4 with 4 gig ram running android Os, the system was drawing some power so it would randomly shut off for no apparent reason. Took a min to figure out but all you need is a real power supply not a usb charger it will not work. Your Pi will actually run hotter with a phone charger adapter. Hope this helps someone, power is everything....
