Customers are saying

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.

    This hasn't given me any problems so far. It's supposed to only give me about 2 min of time to shut down my PS4 before losing power, but I guess that's enough time. The guy at the store said that I could get more time by only plugging in my PS4 to this and not the TV, which makes sense, but I'm not sure how i can navigate the controls on screen to shut down the system if I can't see the prompts on screen to do so (with the TV having lost power).
