Fine surge protector and outlet, but still waiting for an emergency

  • Nov 17, 2010
  • by
At the moment, this box is serving as an excellent multi-outlet power source and surge protector for my laptop, external monitor and a desk lamp, and soon I'll be adding a set of speakers. We haven't had any power failures since I received this, so I can't comment on other reviewers' notes that the battery life is too short to really allow effective shutdown. I can say the alarm works just fine, however: it went off every time I unplugged the unit to move it to a new outlet. It also shut down just fine when my wife plugged our vacuum cleaner into it. Shortly thereafter, we found the note in the instruction manual, I think it was, saying not to use this with vacuums or other larger machines. I do like that this unit has a couple of holes on the back so it can be mounted to a wall: I'm still considering doing that. Until high winter winds give me the chance to see how this performs in a blackout, I'm pretty satisfied with this as a surge protector with a promise for the future.
