I plugged my 8800L Mifi into the general charging station that I have set up and received a message that the device would charge slowly unless plugged into the charging cube that came with it (I was already using the charging wire than came with the 8800). I plugged the Mifi into the correct cube using the correct cord, and the darn thing is now charging even more slowly than it was before. In the past hour, it’s gone from 14% to 15%. The only thing that is running off it is my ipad on which I’m typing this and my husband’s on which he’s playing solitaire. We have 3 bars of 4G, but the results of a speed test were lousy. Can anyone tell me why this thing is taking so darn long to charge? Thanks in advance.
