Tired of struggling with flat cell phones and devices during load shedding? Have a look at our F4 powerbank / charger, especially if you already own multiple 18650 batteries which will bring your cost of purchase way down. For that reason, the powerbank is NOT bundled with batteries but you can purchase our 2500Mah/3000mah 18650 protected flashlight batteries. This high capacity capable powerbank is also a fully capable Li-ion 18650 battery charger for occasional charging application. For regular 18650 battery charging rather have a look at our standard chargers as inserting and removing batteries will be a slight bit easier on our standard models. The F4 was thus not quite intended for everyday charging/removing of batteries. This devices features a LCD screen and is capable of handling 1 to 4 batteries at a time. Two USB output ports are included with a maximum output current of 2Amp. a 2Amp USB wall charger is recommended for optimum charging of the powerbank although most other chargers will also work, just slower.
