In general, a package of batteries is discarded after use.
To solve this, we suggest Charging Pack.
You don’t have to discard this item. It is designed for sustainable use.
It uses sunlight to charge a battery.
Charging pack is a brilliant item to compensate the problem that battery is a waste after use.
Once the battery’s life is ended, it starts to be used as a charger by using sunlight.
This item with a form of thin plastic panel has a solar cell on the front which accumulates sunlight. If the battery socket and the folding part at the bottom are all unfold, it is completely flat. It is a very small volume.
