|Bought 17 July 2012 for use as backup for my desktop computer in the shack and possible "emergency" radio operation. Looks great. Worked great -- for about three days. The unit started developing a problem with the ON / OFF power switch: I couldn't turn-off the unit without using a long house key to reach the switch. The problem degenerated: you could turn the unit on, but you couldn't turn it off. Apparently the ON /OFF switch wasn't working for "OFF". |
I always unplug the UPS for the night. Because the switch to turn off the no AC "ALERT" also wouldn't work, I twice had to disconnect everything from the UPS and remove the battery to get the supply to quit "beeping". And, afterwards, reinstall the supply.
While the manufacturer has made arrangements send me a replacement supply, I simply don't trust this product. It's going back to the retailer for a refund.
