Parent-child Charger / Charger

Parent-child Charger
Parent-child Charger

Rechargeable batteries can re-use and reduce pollution. But they not only add some cost to user but also can not take at any time anywhere; especially they are not convenient to take in outdoors or in a tour. This design combines the function of charger and battery, so you needn’t buy a battery charger, and gain electric power without battery charger.It’s a rational and practical design.The Parent-child Battery (outside) is a charger itself, it can contain two rechargeable batteries. When using it, two rechargeable batteries provide electric power inside. When using small batteries,you take out the small rechargeable batteries from D battery.
