To charge your WakaWaka Pocket Light from the grid you can use a micro-USB cable and charger. This is the same USB cable and charger as used for an Android device for example, and it is sold at most electronics stores. You can also use an iPhone-charger (only with 5V output model) together with a micro-USB cable (not a lightning cable).
You can also charge the WakaWaka Pocket Light with a WakaWaka Power+, Power 5, Power 10, Solar Panel and Sunlink, Base 5 and Base 10.
The WakaWaka Pocket Light is fully charged after 1,5 hours on the grid.
