The SKYROVER S1 Battery Charging Hub helps you stay in the air longer by providing a convenient way to recharge and store multiple S1 smart flight batteries. The hub features three charging bays and powers batteries sequentially when connected to a compatible 30W USB PD charger (not included), ensuring the first battery is ready to fly again as quickly as possible. All three batteries can be fully charged in approximately three hours. When charging is complete, the hub also functions as a compact storage solution, making it easier to transport and organize your batteries while traveling.
