SKE Mini UPS 20000mAh for Router and Modem

At number 7 in this guide, the SKE Mini UPS is the odd one out: it is the only unit here sold without a VA figure at all. Where the others run from 550 to 2200VA, the SKE listing simply gives a Maximum Power of 20 watts, repeated under Output Wattage and Wattage, and sells the box on battery capacity instead — 20000mAh of lithium. It is a 5V/9V/12V DC device built to sit behind a router or modem, not a mains UPS that can carry a desktop PC through an outage.

That narrow job is where the rest of the listing starts disagreeing with itself. SKE claims the 20000mAh battery will power a router and modem drawing 20W for up to 7 hours; one buyer who took it to a part of Africa with limited electricity reports staying connected for more than 10 hours through an outage, and another ran a router, an analogue telephone adapter and the phones across a 5-hour cut without interruption. The same specification then records the form factor as 'Rack' on a unit measuring 20.6 x 12 x 3.5cm that weighs 0.65kg, and the power plug as Type A, 2 pin (North American) on a product whose own name includes UK. Everything on this page comes from the Amazon listing, not from testing by us.
