Tripp Lite 1500VA 900W UPS Battery Back Up Tower AVR 230V 8 C13 USB LCD (OMNIVSX1500)

Not all that impressed by the build quality of this unit - the plastic is wobbly, in particular the panel with the sockets in it, which doesn't inspire condifence. In any case I carefully plugged it in, it reported 60% charge, so I let it charge up completely. Then plugged in some equipment that it reported as drawing next to no load (basically my broadband router and a couple of network hubs which have very small power utilisation) and tested it. The battery indicator dropped from 95% down to 13% in about a minute. All the while the unit was making the most repugnant smell and has gassed me out of my living room. Definitely not fit for purpose and quite possibly dangerous. It's gone back in its box and I'm awaiting collection and refund.

Completely silent, kicked in when power went down. Could ask for more. Bought a second one for garden office.Doesn't come with power lead
