While the FedEx guy probably hates me now, because these F3800’s weigh A LOT, and I ordered two, these showed up in perfect condition and ready to go. Plugged them in and they were both at about 85% charged when I received them, immediately hooked them up to my new transfer station and began running two refrigerators, sump pump, and mech room items like a network switch, router, modem, etc. and the 3800’s ran great. Fans are quiet and display isn’t obnoxious. If there is anything I might wish could be changed is how the Double Power switch is so big and heavy but doesn’t have any mounting keyholes or other hardware to secure to a wall or such. I plan on getting some 1.5” conduit hangers to resolve this though. All in it’s going to be a continuous party next time the power goes out over here!
