Portable tool-battery power

Use a compatible M18-style battery as a compact DC source for Starlink Mini.

This cable connects an M18-style slide-battery socket to a DC5521 barrel plug. Select the length that gives your camp or field setup enough routing room without excess cable.

Cable construction

Built for a tidier portable route.

Reinforced strain relief and 18 AWG PVC cable on the M18-compatible DC5521 power cable
Reinforced strain relief at the battery-socket cable exit.

The supplied specification lists an 18 AWG PVC-jacketed lead. Route it away from sharp edges, pinch points, heat and moving parts.

  • For Starlink Mini only: do not use as a direct dish-power cable for Standard, Standard Actuated, Gen 2, Gen 3 or Performance systems.
  • Battery fit: intended for the newer M18-style slide-battery format; it does not fit the older V18 / 48-11-2200 style.
  • Before power-on: inspect the connector and cable, then confirm polarity and electrical requirements for the exact setup.

Quick answers

What this cable does—and does not do.

Does it regulate voltage or charge the battery?

No. It is a direct-output cable only; it does not regulate voltage and does not charge a battery.

Is a compatible battery included?

No. The cable is sold separately from the M18-style battery.

Can I use it with another Starlink model?

No. This product is presented for Starlink Mini only. Other Starlink systems use different power hardware and should not be connected directly with this DC5521 cable.

Complete your Starlink Mini setup

Choose the remaining pieces for your own use case.
