    I bought this to charge all my devices and it works great but I do have to get either another one or a stronger one.

    Very glitchy, software issue?

    This thing makes me nervous, I think it has a software issue. I'll have the battery pack charged to 70 or 80 or even 90 and all of a sudden I'll look at it and it'll be flashing a one I have no idea what it means but plugging it in sometimes seems to maybe reset it, it's just very glitchy. I thought maybe it would improve by the time return. Was over but that already passed. I have a similar Anker one that's a little smaller capacity but it's very reliable. I would recommend that brand instead.

    I bought this portable charger exactly a year ago (Black Friday 2023). It has discharged & can't be charged up anymore. Although it helped us a few times when we need to do a quick charge, we never let it go less than 70%. Its a heavy brick and not very portable. It adds significant weight to both my workbag or purse. A great thing it can charge multiple devices at the same time and has variety of outlets for different charger wires.

    Great for traveling non the go while you need to charge your phone. Two outlets so that you and a friend can charge at the same time, and has multiple inputs for you to charge. (USB-C, Micro USB, and input)

    Works really great. I purchased a different brand a few years ago and it did not not stay charged very long. However, I would recommend this charger to everyone. It out performed my expectations.
