FFpower 2000W Portable Power Station

I have this as a power backup for a dorm-sized refrigerator and freezer. Max wattage draw combined about 110 watts when running, but each has a short duty cycle. I need the backup because of the California planned and unplanned blackouts. Based upon the front display, this thing will keep the units powered for an estimated 20-24 hours. It is a bit heavy, but not nearly as much as if it had a lead acid battery. I didn't have any trouble moving it around. The ergonomics are well designed. My only concern is that although the pass through voltage is line level (120VAC), when the unit kicks in it's only 110VAC (verified with a multimeter). That means it increases the current a bit which isn't good for inductive loads, but I imagine most appliances have a 10% voltage tolerance. Overall, if you can afford the expense it's well worth it. Quiet, and you can monitor it continuously on the front panel. Switchover to battery power is essentially instantaneous and seamless. I'd buy another if it weren't so expensive.
