A:AnswerMy pocket juice turns off automatically if it's not being used and it turns on when it is being used. The reason why there's only 2 of the 4 lights lighting up is because it's showing you how much battery it has, so it's halfway charged. I hope that helps.
A:AnswerAll I do is switch the end around; plug the small end into the Pocketjuice item and then plug the big end into a port on your computer; make sure the computer is on and it will charge it up. Takes quite a while to charge it, several hours.
A:AnswerNo you can't use it as a wall charger at home. The instructions say not to charge a device and have the pocket juice plugged into the wall at the same time.
A:AnswerThis power bank charges my iPhone 7 Plus 5-7 times on a full charge. It takes awhile for the bank to charge fully when you’re charging it from a power source.
A:AnswerIt seems you have the same one I have. If it is powered low, the blue bars will start to go up as it reaches the highest level. On mine, once "filled" all four blue bars are on (not blinking). I have not had an issue if I keep it plugged in (like once I go to bed and it's full by morning).
