The rechargeable 2,400mAh battery in this multi-functional item powers the lantern and the flashlight, so you won’t need to buy batteries. It also functions as a power bank to charge your phone. The flashlight and the lantern both have adjustable brightness levels and functions. An additional feature of this model is the solar panel, which can also be used to recharge the battery. The solar charging is quite slow, and simply functions as a back-up option when you don’t have power available to charge the battery, or if you’d like to leave it charging with exposure to sunlight for a period of time.
