This eliminates the need for individual battery swaps and reduces overall charging time. Use with the 240W Power Adapter to fully charge one battery in 51 minutes or three batteries simultaneously in 90 minutes. By leveraging the batteries' stored power, it transforms into a 100W power bank, providing a convenient way to fast-charge your devices.  It features a power accumulation function, which allows you to transfer the remaining power of multiple low-power batteries into the battery with the highest remaining power.
