Mango Power E Home Backup and Portable Power Station

Excellent. I am 79 years old and on an oxygen machine 24/7. I needed a machine that I didn’t have to turn on when the power went off. I was surprised by this feature. I have recommended to a friend.

So far, so good

Power station works really good itself, the only downside is it does not offer pass-through charging. The app to control it on your phone is pretty much useless at this point, lots of bugs. Item was on sale so it's worth it, however at full price, there is better options out there
