Black rectangular power adapter with 6.6 ft cable and barrel connector

YJWJMZZ SPM9551 power adapter 12V 6.6ft

SKU CH-XCQK-DT35G MPN SPM9551

Replacement 12 V AC adapter with 6.6 ft cord and over-voltage, over-current, short-circuit and over-temperature protection for Spektrum DX transmitters

  • Worldwide voltage input 100 – 240V for travel use
  • Steady 12V DC output powers Spektrum transmitters reliably
  • Extra-long 6.6 ft cable gives freedom from wall sockets
  • Over-voltage and over-heat protection guards connected gear
  • Tested replacement matches SPM9551 spec for DX8, DX7S and more

Compatible replacement adapter

This AC adapter replaces the Spektrum SPM9551 charger for DX18, DX18QQ, DX10T, DX9, DX8, DX7S, DX7 Gen2 and DX6 Gen2 transmitters. It accepts 100 to 240 volt input at 50 or 60 hertz and delivers 12 volt DC output. The 6.6 foot cord gives extra reach at the bench or field box.

Sustained-load behaviour

Over-voltage, over-current, short-circuit and over-temperature protections guard the transmitter during long charging sessions. The supply maintains a steady 12 volt output without tripping when the radio draws continuous current. Heat protection prevents shutdown during back-to-back flight days.

Build and connectors

The unit is a compatible replacement tested for safety and certified with CE. A barrel plug matches the Spektrum transmitter jack for a secure fit. The 2 metre cable resists tangling and reaches wall outlets without an extension lead. The compact housing sits flat on a workbench or charges inside a flight case.

Questions about this item

Does the YJWJMZZ SPM9551 power adapter run hot or make noise when powering a transmitter all day?

The unit includes over-temperature and over-heat protection, so it shuts down safely if internal temperatures rise too high during extended use.

What connector does the SPM9551 need on my Spektrum transmitter for it to work?

The adapter is built for Spektrum DX18, DX18QQ, DX10T, DX9, DX8, DX7S, DX7 Gen2 and DX6 Gen2 transmitters, so the matching barrel jack must be present on the radio.

Will the 6.6 ft cord reach my older DX7 charger station without an extension?

The 6.6 ft cable length gives ample reach for most bench setups, letting you plug the adapter directly into the older transmitter without extra cords.
