    Great battery, difficult for permanent install
    Posted by Mark McMillan

    The battery is great for my IoT project with a solar panel for recharging. It will run my project for a week without sunlight.

    I wish the case we better for mounting in a project box - it has no mounting holes, and all rounded edges. Very hard to mount properly. Plus the USB and charger outlets are not on the same side, so it requires quite a large footprint inside a project box. I am tempted to take it apart and discard the casing.

    Works great for running a Uhoo AQM so I can move it around the house. The Uhoo goes into low power mode constantly, and it hates being unplugged which makes it want to recalibrate all its sensors for TWO DAYS.

    Solid battery pack, a bit large
    Posted by Tom Tumbusch

    I ordered two of these for travel, and they work great. Love that they're optimized for solar and are USB-C compatible, but I miss the slim, lightweight design of the V15.

    I use field equipment on my job and I do not go anywhere without V25's & V50's in my equipment bag. Highly recommend them.
