Drones with USB charging

 

— ability to charge the battery from a standard USB port.

This feature provides a very extensive choice of power sources. These can be computers or laptops (the presence of USB for such equipment is almost mandatory), adapters for a 230 V outlet or a car cigarette lighter, Power bank batteries, individual models of portable gadgets (via an adapter), or even more specific devices like tourist flashlights or portable generators . On the other hand, the power of such charging is generally small, so this function is found only in small lightweight copters that do not require particularly high-capacity batteries. However, among these copters there are very advanced models — including industrial / commercial ones (see "Type").
