Upgrade the connectivity of your portable power station with the genuine Bluetti B80 external battery connection cable to DC7909 socket. With an ideal length of 1.50m (59"), this cable is specially designed to convert the Bluetti B80 expansion battery into a standalone power station, allowing for direct DC power supply. It connects the P120D expansion plug of the B80 battery to the female DC7909 socket of compatible Bluetti power stations, such as the EB3A, EB70(S), and AC180 models. It is a passive high-conductivity power cable, made from pure copper conductors and a reinforced PVC/TPU casing for maximum bend resistance. It is the most reliable and safe choice to extend your equipment's energy autonomy during outings, camping, or emergency situations.
