Running out of battery is one of the main concerns for drone pilots, especially when this happens in a place where no electrical socket is available. Suppose you need your smartphone to run DJI Fly app to check real time video feed from your Mavic Air 2 or simply you need to configure Betaflight through Speedy Bee app and you are with 5% battery left: that is a bad situation.
Fortunately, devices called power banks exist: these are literally portable energy through which you can recharge your smartphone or other USB devices.
In this article we take a look at the BlitzWolf BW-P11 20000mAh 18W QC3.0 PD Power Bank.
BlitzWolf BW-P11 is a power bank from BlitzWolf which is able to store 20000mAh. This is a good amount of charge capacity: in fact it means that, considering a smartphone equipped with a 4000mAh battery, it can be full charged 5 times.
