    Super excited about this purchase. I have not used it yet...but we do lose power frequently, so I'm grateful to now have this on hand to charge my phone/Ipad- and/or make my phone a hotspot. It for sure lessens my anxiety when I know a storm is coming. (or the wind blows, or it sprinkles gently, or the weather looks crossly at our electric wires.) PLUS, it was on sale half off, AND, I had a coupon! I mean... The charger/power bank comes fully charged. So you're good to go straight out of the box.

    When the power goes out this is a lifesaver. Holds a good charge and is good to have on hand. It's also compact and portable.

    Pretty heavy but works great. Charged my phone and it barely used the battery. I would recommend this especially if you are always on the go.

    This battery pack holds a lot of juice but doesn't pack the punch to charge something like a steam deck or nintendo switch. I was a little disappointed with it but still ended up using it more than I thought for my small electronics. Charging the bank itself also takes a few hours which I found long.

    Charges slowly unless you have a really powerful charger but once it is charged it's a powerhouse pun intended.

    Bought for my son who was heading off to boot camp! Best purchase ever! He has dropped it and it has been put through the wringer and it still works. It holds a charge very well. Had it for 2 months before he even had to charge it. Highly recommend!

    They typeC to typeC connector for fast charging does not work for my Galaxy Fold or my wife's iPhone 13 when connecting to the typeC plug. Only USB to phones typeC charges and it is normal not fast charging. Slow charger, but does have a long life.

    Charges a bunch of times before dying. Would recommend for long trips or any type of a vacation. It is on the heavier side though only downfall.
