Man this portable battery is the best of the best. It works for a 4 days stay in the woods to charge your essentials and eve and air matress.
I shared the juice of this thing with several friend in the camping ground and that was last week. Today, I have 67% battery left! awesome!

Dependable Savior

Great way to keep me using my CPAP machine during a power shortage. I would strongly recommend purchasing a NEW one with a 5 year warranty. Don't know when there will be another power outage in my apartment complex.

This design feels sturdy and it will work great if you have a few days away from a reliable power source. I made use of it at a music festival and had no problems keeping all of my devices charged.

This has been a fantastic purchase. We are able to use it for hours with no issues or worries of it dying. The digital display is very crisp as well!

I really like my 521, but I’d lose to see more usb-c ports on these as they seem to be the way things are going.
