This Bluetti DC7909 to XT90 Cable is used in combination with the Bluetti EB200 or the AC200P 400W PSU and the Xt90 to aviation plug. With an AC200P 400W PSU adapter it is possible to charge the Bluetti via the wall socket. A 400W PSU is already supplied with the Bluetti AC200P as standard. If you want to halve the charging time of the Bluetti AC200P, this is possible with a second Bluetti AC200P 400W PSU, in combination with the Bluetti DC7909 To XT90 Cable and the Xt90 to aviation plug.
