The Futaba FUAL0090 adaptor cord is an accessory for RC transmitters that bridges the transmitter battery socket to chargers using a barrel connector. It provides a fixed-length lead so you can reliably place the transmitter on a bench or holder while charging.
The main physical details are the 1500mm cable length and barrel dimensions OD5.5mm/ID2.4mm, which determine compatibility with your transmitter and charger sockets. Check those sizes against your equipment prior to use.
Fitting tips: avoid tight bends at the connector, secure the cable with ties or tape where it runs over edges, and inspect polarity markings before applying power. The cord is passive and does not alter polarity or voltage.
Use cases: extend the reach of chargers that have short cables, set up a repeatable charging point for multiple transmitters, or keep the transmitter conveniently positioned while topping up batteries.
