Portable Power for Starlink: What to Check Before You Buy a Power Station

Power stations are sold on headline capacity, but what decides whether one suits Starlink is a short list of numbers on the dish and on the station. This guide uses Starlink's own Standard specification sheet, Mini specification sheet and Standard and Mini accessories guides, all checked on October 5, 2026. It does not name or rank specific power stations: we have not tested any, and a recommendation without testing would be a guess. It gives you the checks to run on any unit you are considering.

Step 1: what the dish needs

The sheets give averages, not worst cases, and they do not say how much a heating dish draws in snow or how much the router adds. The Standard sheet lists snow melt of up to 40 mm per hour and the Mini up to 25 mm per hour, so winter use is the case where a plain average is most likely to under-state the draw. If your plan depends on a tight margin, measure your own kit with a plug-in power meter.

Step 2: runtime arithmetic with stated assumptions

Runtime in hours = battery watt-hours x conversion efficiency / draw in watts. The efficiencies below are our assumptions for illustration (85 percent for an AC inverter path, 90 percent for a DC or USB-C path), not measurements of any product; use the maker's own figures for a real unit. The example battery is an assumed 500 Wh.

To size the other way, multiply the draw by the hours you need. Running a Standard for an 8-hour night at 100 W takes 800 Wh at the dish; at 85 percent efficiency that is 800 / 0.85 = about 940 Wh of battery. A Mini at 40 W for the same night takes 320 Wh, or about 360 Wh at 90 percent. A full 24 hours is 1,800 to 2,400 Wh for a Standard (75 to 100 W) and 600 to 960 Wh for a Mini (25 to 40 W) before any losses. Our Power Sizer runs this calculation with your own numbers.

The Mini is the practical choice for battery use: its draw is about a third of the Standard's, so the same battery lasts roughly three times as long on these figures. The trade-off is the dish itself, which the dish comparison covers.

Step 3: five checks on any power station

1. Usable watt-hours, not the headline. Use the maker's rated capacity and ask what the rated AC or DC output efficiency is. Treat our 85 and 90 percent as placeholders until you have that figure.
2. Output type for your dish. A Standard on its stock power supply needs an AC outlet. A Mini needs either a 12-48 V DC output delivering 60 W or a USB-C port that can deliver 100 W at 20 V / 5 A. Many USB-C ports on stations and banks are rated below 100 W, so read the per-port rating. Starlink's sheet gives 100 W (20 V / 5 A) as the minimum, and its 5 m USB-C cable is described as designed for the Mini, not for charging devices.
3. AC continuous rating with headroom. The Standard's power supply label reads 100-240 V ~ 2.5 A. At 120 V that current rating corresponds to 300 VA, which is a ceiling on what the supply can draw, not its normal load. We would look for an AC continuous rating of at least that, and more if the router or other devices share the same outlet. This is our conservative reading of the label, not a Starlink requirement.
4. Runs while charging. If you plan to add solar or charge from a vehicle while the dish is running, check the station's own documentation for whether it supports using outputs while the input is connected (often called pass-through), because designs differ. Charging input limits decide how much of the draw solar can offset; the off-grid guide works through solar sizing.
5. Temperature range.Both Starlink sheets list an operating temperature down to -30 °C for the dish, but a battery has its own limits for discharging and charging in cold or heat. Read the station maker's operating and charging temperature ranges against where you will actually use it.

Station, bank, or vehicle power?

For the car adapter and the 5 m USB-C cable, see the Mini travel gear guide. If your goal is surviving a home power cut rather than travelling, the UPS guide covers that case and the router.

Before you buy

1. Decide Standard or Mini, since it changes the battery you need by about three times.
2. Pick the hours you need and work out watt-hours with the arithmetic above or the Power Sizer.
3. Match the output type: AC outlet, 12-48 V DC at 60 W, or a USB-C port rated 100 W at 20 V / 5 A.
4. Read the maker's rated capacity, AC continuous rating, charging limits and temperature ranges.
5. Measure your own kit once with a plug-in meter if the margin is tight.
