b) Charge Flight Battery
A suitable USB mains unit or USB cigarette lighter adapter (neither enclosed) may be used for power supply to the
enclosed USB charger; they each must have an output current of at least 500 mA.
Alternatively, the USB port of a computer or USB hub with a dedicated mains unit can be used as well that can supply
a current of 500 mA per port.
Connect the USB charger from the delivery to the USB power supply with its USB plug (1) (as described above, e.g.
a USB mains unit or similar). Then connect the small plug (2) of the USB charger to the corresponding socket of the
quadrocopter (3). Observe proper alignment of the plug (the plug contour must match the socket in the quadrocopter).

signalled by the red LED in the USB charger.
