A Starlink Mini needs a USB-C port that can deliver 100W at 20V and 5A. Starlink sets that as the minimum, so a 60W port, which is what a lot of small power stations carry, is below spec. If you plan to run the Mini off a power station’s USB-C, read the port label before you leave town. Checked October 28, 2026.
What Starlink publishes
The Mini spec sheet lists three numbers that matter here:
- Power consumption: average 25 to 40W.
- Input rating: 12 to 48V, 60W.
- USB PD requirement: “100W, 20V/5A Minimum (with Starlink USB-C to Barrel Jack Cable Accessory).”
Starlink’s USB-C cable article says the same thing: the cable “requires a 100W 20V, 5A source.” It also says the cable is built only for the Mini, and that the USB-C end should not be exposed to the outdoors. The barrel jack end is the weatherproof one.
So the dish averages 40W at most, and Starlink still asks for a 100W port. Starlink does not explain the gap on either page, and we are not going to guess at the engineering. The practical reading is simple: Starlink publishes 100W as the floor, so that is the floor.
Reading a port label
A USB-C port’s rating is often printed as a list of voltages and a current, like “5/9/12/15/20V, 3A, 60W Max.” The two numbers that matter for the Mini are the top voltage and the current. You need 20V and 5A. A 3A port tops out at 60W at 20V, whatever else the label says.
Worked example: EcoFlow’s published specs for the RIVER 2 list its USB-C port as “5/9/12/15/20V, 3A, 60W Max,” and the user manual gives the same figure. That is 40W short of Starlink’s minimum. Those are EcoFlow’s UK page and EU manual; the US product page we fetched did not show a port table. Port ratings vary by model, so read yours.
The route that skips USB-C
The Mini’s own input is 12 to 48V at 60W, which means a 12V DC source sits inside its rating without USB-C in the middle. The same RIVER 2 spec lists a 12.6V, 8A, 100W DC output. If your station or your house battery has a 12V outlet, a 12V-to-barrel-jack cable is the cleaner path. One caution: 12V is the bottom of the Mini’s input range, so there is no margin below it, and we have not tested what the Mini does when a battery sags under load. We have not tested any third-party cable, so buy one rated for the load and check the polarity and plug size against your Mini. Our Starlink guide covers why DC beats running the kit’s AC power supply through an inverter.
The runtime math
Divide watt-hours by watts. A 256Wh station (the RIVER 2’s rated capacity) at the Mini’s 25 to 40W average gives about 6 to 10 hours. That is before conversion losses, which we have not measured, so the real figure is lower. A full work day plus a laptop needs a bigger station or solar coming in. Run your numbers through the RV solar calculator, and see internet while boondocking for when cellular is the cheaper answer.
The verdict: check for 20V and 5A on the USB-C port, and if it says 3A, power the Mini from a 12V DC outlet instead.
