I just charged up this product with its expansion battery. Only used it a little to check out some plug-in functions. I wi test ut out next hurricane season. I'll up date my review next year.

I love it . That's a good quality built power station. I charge it with solar panels and used it for small electric appliances. Will try to add more expansion batteries later.

I'm pleased with the capabilities of my F3800 & expansion battery. The phone app is really cool & easy to update both the unit & battery. My major concern is that it's too cloudy most the time with all the planes... I'm not sure if solar panels will keep it charged.

Quiet, always ready and very portable. My neighbors like me again!

I bought this unit to be ready in case of a power failure. My electrician installed the transfer switch and we tested the unit and everything worked great! I hope I don't have to use it but now I know I'm better prepared.
