    It was on sale so I bought the same brand that died on me after three years of use. I would think, seeing as I rarely used the battery function except to turn off my computer during Island Gales when the power went out, that it would have lasted a bit longer, but as I said, it was on sale. I would recommend it to a friend if they get it on sale.

    Only issue is that it may be too small for all of the electrical items I use. So far all is well.
