Mobile Power Bank

A mobile power bank is the pocket battery people carry when a phone, earbuds or handheld gadget has to keep going away from a wall socket. By our assessment, it is good at the one job it exists for: giving a dead or fading device another charge in transit, on a commute or during a long day out. The limit is obvious too, because it is only stored energy in a box, so you still have to remember to charge the bank itself and live with the loss that comes from moving power around. In practice the appeal is very ordinary: cables, a button, a few LEDs or a small display, and then the waiting while the battery trickles energy into something else. Mobile Power Bank sits between a charger and an emergency reserve, not a full replacement for either. It is for people who spend time away from outlets and do not want the phone to decide the schedule.
