I purchased this one:
I plugged it in just now and it works, but it seems to always be on battery most of the time... Like for a minute it will be running like a normal power strip and then the BATT. icon appears and it starts using battery... I was just curious what I was doing wrong here...? It simply says in the directions to plug it in and it is good to go, but it is still using its battery and I don't know how to make it stop...
