    Bought higher capacity power bank with high expectations that the product from a reputable brand with wireless charging technology, but wireless connectivity drops every minute and continues charging not functioning even with cable, battery backup also poor.

    It’s not the best quality. Stopped working after a couple months & the power button snapped. But Energizer customer service is the best, they sent me a new device and apologized for the inconvenience.

    The USB-C plug works well and it isn’t too heavy, which is what I wanted it for. However, I’ve had a hard time getting my phone to charge sitting on it.

    Wasn’t sure whether or not the thing was charging at any given point in time because the indicator light was confusing and the power button combined wasn’t intuitive enough to make sense. I think it charged slow, and I couldn’t recharge the things I ended up having to return it.

    Purchased to charge my S22 while traveling. I already have a wired charger that works very well but liked the wireless charging option. It starts to charge my Android but turns off after a minute. I kept turning it back on and it kept turning off again. The battery level never increased.

    Works very good, a little bit bulky and heavy but it is relatively logic due to the energy storage capacity.
