Rear window (Cirrus SR20/22, Cessna 172, etc.) - the best placement for most aircraft. People use suction cups, Velcro strips, or custom mounts. The DIY element is unavoidable here.
Glare shield - works if your front windows are not electrically heated. In practice the connection quality is acceptable, but store the device for takeoff, approach, and landing, and make sure forward visibility is not compromised.
Side windows - only reliable if the window faces roughly north. Works on some headings but not a dependable solution in general.

How to power the Starlink Mini

The Starlink Mini ships with a 110V/230V wall adapter only. The device itself accepts 12–48V DC directly, which makes aircraft installation straightforward. Specifications say up to 60W; in practice it draws 30–40W at startup and settles to around 20–30W during normal operation.

A cigarette lighter socket at full aircraft voltage (14V or 28V) is the simplest solution. Check the amp rating of the socket - at 14V you need at least 3A continuous.
If your aircraft has a 12V converter (common in some Cirrus models), verify it can supply sufficient amperage before connecting.
Connect directly to the aircraft supply if possible. Do not add a USB-C adapter in between - these introduce additional losses and increase the load.
Standard USB-A sockets cannot supply enough power. Do not use them.
Power banks can work and give roughly 2 hours of runtime with a suitable high-power unit (see tested recommendation below). Not ideal for permanent installations, but useful for occasional use.

WXStar connects between the aircraft power supply and the Starlink Mini, so with WXStar installed you only need one power connection for both devices.

Tested components (optional reading)

We have no business relationship with any of the products listed below and receive no commission or other benefit from mentioning them. These are simply items we have personally tested and found to work well with WXStar and the Starlink Mini.

Power bank (if aircraft power is not available)

Anker 737 Power Bank, 24000 mAh, 140W
Provides approximately 2 hours of runtime for the Starlink Mini + WXStar combination. The 140W output is enough to run the Starlink Mini at full load. Heavy (approx. 800 g) — not suitable as a permanent fixture but works well for occasional flights where aircraft power is not accessible.

USB-C to Starlink DC power cable

EDUP USB-C to Starlink Mini DC power cable, 2 m, PD 100W, 18AWG, waterproof
Connects a USB-C power source (such as the Anker 737 above) directly to the Starlink Mini DC input. We have tested this cable and confirmed it works. Make sure your USB-C source supports at least 65W PD output to avoid undervoltage dropouts at startup.

Where to buy

Local retailers let you select the correct Starlink plan immediately. Typical price 300-350 EUR.

The producer of the WXStar DIY Kit is WXStar UG (haftungsbeschränkt), Berlin, Germany. Golze Engineering is a dealer for this product.
