Short answer: on current Standard kits, the dish already gets its power over the Starlink cable from Starlink’s own power supply, so there’s nothing to add: the Standard 4 supply has two PoE ports, and on Standard 4 X the Starlink cable runs from the dish to Router 3, and the power supply plugs into the router. Starlink’s current setup and accessory guides don’t list a separate PoE injector, so any standalone injector you find for sale is a third-party part, and the Starlink Mini doesn’t use PoE at all; it runs on 12–48 V DC.

| Kit | How the dish gets power | Starlink’s DC option | Source |
|---|---|---|---|
| Starlink Mini | DC input (12–48 V, 60 W) or 100 W USB-C PD with Starlink’s cable; not PoE | Feeds on DC directly; Mini Car Adapter | Mini spec sheet |
| Standard 4 | Starlink cable from the dish to either port on the power supply, which Starlink’s guide calls “Dual PoE” | Standard DC-DC Power Supply (select markets; check the Starlink shop) or AC/DC Advanced Power Supply, per Starlink Help Center | Standard 4 setup guide; Help Center |
| Standard 4 X | Starlink cable from the dish to Router 3 port 1; the power supply plugs into Router 3 | Standard DC-DC Power Supply (select markets; check the Starlink shop) or AC/DC Advanced Power Supply, per Starlink Help Center | Standard 4 X setup guide; accessories guide; Help Center |
| Older kits (Gen 1, Gen 2, Actuated) | See our older Starlink models guide | None current | Starlink Help Center setup guides |
What PoE means on a Starlink cable
Power over Ethernet means one cable carries both data and power. On Standard 4, the Starlink cable does this between the dish and the power supply. Starlink cables use Starlink’s own connectors, and Starlink doesn’t list any generic PoE switch or injector as compatible.
Why people search for an injector
- Running off 12 V or batteries. Starlink’s own route for Standard 4 and 4 X is a DC-input supply; see our Starlink 12V guide and backup power guide.
- Skipping the Starlink router. Use bypass mode instead; see bypass mode with your own router. The dish still needs Starlink’s supply.
- Adding wired devices. Starlink’s setup guide says to plug your own Ethernet cable into Router 3’s extra port 1 or 2 to connect third-party hardware; see our Ethernet adapter guide.
Risks of non-Starlink injectors
Third-party injectors are sold with switchable outputs; one maker’s manual (Direktronik) lists 48 V PoE output for its “Standard” model and 57 V for its “Actuated” model, each switchable to 24 V, and the maker warns that the powered device must support that voltage “otherwise the device will be damaged.” Starlink doesn’t publish PoE voltages or approve any third-party injector, so the wrong model or setting can damage your dish. Starlink’s Standard 4 guide lists power supply fault lights for PoE output current too high, voltage too low and voltage too high, and turns PoE off after a short circuit. These injectors aren’t Starlink parts, and we don’t recommend them.

| Standard 4 power supply light | Meaning (Starlink guide) |
|---|---|
| Blinking white | PoE port ready |
| Solid white | Both ports delivering power |
| Orange, 1 / 2 / 3 blinks | Output current too high / voltage too low / voltage too high |
| Red blink | PoE off after a high-power event such as a short circuit |

FAQ
Is the Starlink cable PoE?
Yes. On Standard 4 the Starlink cable carries power and data between the dish and Starlink’s “Dual PoE” power supply; on Standard 4 X it runs from the dish to Router 3.
Do I need a PoE injector for Starlink?
No. Current kits ship with everything that powers the dish.
Does Starlink Mini use PoE?
No. It runs on DC or a 100 W USB-C source.
