I still had 8% battery charge when I plugged it in to charge. 40 minutes later it was a full charge at 100% That is the fastest charging battery I have ever had!

Flexible Power Station

It's a great, flexible power station. It offers me a very substantial UPS daily (allowing me to continue to work from home, uninterrupted, during intermittent power outages) with the added flexibility to support my family power needs when camping, etc.. When camping, I can run my CPAP for 3 nights without a recharge.

Purchased for piece of mind

The item ordered arrived on time. The set up instructions were easy to follow. Tested out the unit to make sure it was working as expected. While I haven't had an extended power outage yet, I am confident that this unit will handle my needs.
