This Futaba FUAL0090 adaptor cord is made for RC transmitters to link battery ports with chargers that accept a barrel connector. The fixed 1500mm length lets you position a transmitter on a stand or workbench without strain on the built-in cable.
The defining physical details are the cable length of 1500mm and barrel connector dimensions OD5.5mm/ID2.4mm. Those measurements determine whether the plug will seat correctly in your transmitter or charger.
Practical advice: keep the cord free of sharp kinks, anchor it where it crosses edges, and double-check polarity labels on both ends before powering up. This is a passive cable and does not provide polarity inversion or power conditioning.
Practical applications: use the adaptor to extend charger reach, set up a permanent charging point for workshop transmitters, or create a consistent connection point during regular servicing.
