Many also appreciate its affordable price, ease of use, and compact size, with several noting the convenient number of outlets. A small number of users mentioned a noticeable humming sound when the unit is running on battery power, and the lack of a USB connection was also cited as a drawback by a few customers.

    reasonable price for a good power backup unit. I like the large plug areas for common large adapters that take up more room than normal plugs. Very handy.

    Gives me enough time when power goes out to complete what I need to do. Usually the power comes back on before the backup feature wears out.
