Customers have mixed experiences with the power supply of this charging adapter.

    5.0 out of 5 stars Works Fixed Low Voltage Warning
    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.

    I am very impressed with this power supply! It provides a consistent and reliable source of power for my Raspberry Pi 4 Model B. The Type-C to Micro USB adapter is a nice touch and ensures compatibility with older Raspberry Pi models. The 5V 3A output is also more than enough for my needs.

    I wanted a power supply that could easily power any of my Raspberry Pi collection, and this does the trick nicely.
    Power switch comes in handy for switching between units without having to unplug the 110 V end each time.

    Reviewed in Canada on February 22, 2023
    Verified Purchase
    I’m using this on a Raspberry Pi 4 (8 GB) and the on/off switch makes it easier to power the system on and off than plugging in and unplugging the cable. It is worth upgrading for this reason alone.

    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

    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.

    The power supply for my Pi 4 stopped providing enough voltage and was giving errors. Swapped it out with this one and has been working great. I do like the power switch on it... not all of pi power supplies come with a nice power switch like this one.

    4.0 out of 5 stars Nice switch & cord, good (but not great) power supply
    Reviewed in the United States on January 11, 2021
    Verified Purchase
    The switch and cord of this power supply are well constructed and fell very heavy duty. I also like that it is a toggle switch (although it's unlabeled) so I can see what position it is in (e.g. before plugging in my pi).

    The power supply itself is good. Although simple (a plain inverse relationship between voltage and current) the voltage is well contained in tight tolerances. This sort of design depends on the factories testing & calibration, but mine is spot-on (minimal load voltage 5.2V, 3A voltage 4.9V, under-volt cutoff at 4.8V).

    The biggest risk is that this sort of design will be temperature sensitive and prone to drift as the components age. There are some adapters in the $10~$12 range with better circuits so I'm unlikely to buy again, but I'll use it.
