The invention relates to a battery-to-battery charging device, method of charging and use of the charging device. The method comprises steps of discharging a battery to a power connector using a charging engine, wherein a receiver battery is separably connectable to the power connector, sending data on the condition of the battery to a controller, and adjusting the discharge rate of the battery to increase the discharge rate, wherein the discharge rate is increased to a rate of 3C or more. The device can be used for providing fast battery-to-battery charging, in particular from a portable battery to a larger receiver battery (for example an electric vehicle or uninterrupted power supply battery).
