    Reviewed in Canada on July 30, 2024

    Works great for the Raspberry Pi 3 B+ with 7" Pi Display

    I was getting the Low Voltage Warning and found the Pi 3 B+ actually requires a bit higher than 5 volts to operate and around 5.2V is perfect. Other power supplies drop down below 5V, around 4.9V, and will cause the low voltage warning.

    While the functionality of the product works, I found that it emitted a high pitched screech that I could not make go away, even testing it on different devices and outlets. This is a high enough pitch that I am not able to use this charger comfortably (to my ears.)

    5.0 out of 5 stars Not happy update
    Reviewed in the United States on June 7, 2025
    Verified Purchase
    Bought this to replace the adafruit charger I ended up using for another project. When I plugged this one into my raspberry pi I started getting under voltage warnings. Now the pi’s getting throttled. Plugged the original charger back in and the pi’s back to normal. Not sure what’s up with this brand new out of the box charger not working but either way it was a waste of money.
    Update: the seller reached out immediately and offered a replacement. The replacement works perfectly, great customer service. Would definitely do business with them again.

    My PI 3 was giving me warnings about power supply voltage using a cell phone charger, so I picked this up.
    Problem solved! It also includes a USB C adapter plug on a mini-USB cable, so I can use it for charging other devices as well. Best part: It has a power switch!

    5.0 out of 5 stars Finally a Pi power supply that works!
    Reviewed in the United States on February 10, 2025
    Verified Purchase
    I have a pi 3b+ that runs my pihole. I was constantly getting under volt errors no matter what power block I used. Official or not.

    I bought the same brand ssd adapter and along with this power supply I no longer get any errors!

    The build quality is great. The cord length is good and having a switch built in is perfect. It comes with a USBC to micro USB adapter so compatibility should be universal. And it keeps my pi powered up at all times!

    I'm definitely buying all my accessories from this brand
