Nice power pack!

This thing does a great job. I use it on my boat to power lights, fans or the tv in the evenings after shutting down the generator. It works really well. My only complaint is the ear-shattering alarm that sounds when it's about out of juice. It went off at 4am one morning and scared the heck out of us! I wish there was a way to shut it off. Minor annoyance, though, for a really good product.
