How long will a portable power station run Starlink?

Short answer: the Mini is easy on a battery and the full-size dishes aren’t. A Starlink Mini on an EcoFlow DELTA 2 works out to about 23.0 hours from the 12V car port, if you have the right DC cable (more on that below). That’s roughly a day of being online. A Starlink Standard 4 X on the same station gets 8.5 hours, which is a long evening and a night, not a weekend. On a small station like the EcoFlow RIVER 3 Plus, the Mini still manages 6.5 hours. The Standard gets 2.5 hours and that’s about it.

Where these numbers come from

Starlink doesn’t publish one power figure for each kit. Each spec sheet gives a range for average consumption, and we use the top of it. If your dish sits nearer the bottom of its range, you’ll get more hours than the tables show. We’d rather you beat our numbers than come up short.

The Mini spec sheets also list a maximum input rating, which is higher than the average. We read that as a ceiling rather than what the dish pulls hour after hour, so we don’t use it for runtime. None of the sheets give a startup or peak figure, so every row is marked “surge unverified”.

As on the rest of the site, these runtimes are calculated, not measured. We take the station’s rated capacity, apply an efficiency factor for the power path (our assumption, printed under each table) and divide by the average draw. We haven’t run any of these dishes on these stations ourselves.

12V car port or AC outlet?

The Mini, Mini X and Performance spec sheets all list a DC input, so those tables have a 12V row for each station. The Standard 4 X sheet only describes an AC power supply, so its table is AC only.

The DC rows come out a little longer because the station isn’t running its inverter all day. They do assume you have a cable that takes the station’s 12V car port to the dish’s DC input, and that’s not always what comes in the box. The Mini’s DC input, for one, needs Starlink’s own DC cable. Sort that out before you plan a trip around the DC numbers.

Every station here has a car port rated at 10 A. The Mini fits under that with lots of room. By our figures the Performance fits too, but with a lot less to spare.

Runtime by kit

We used the same five stations as our 12V fridge page, from small to very large. The runtime calculator covers the rest of the stations in our data.

Starlink Mini and Starlink Mini X

Both spec sheets give the same average range, so the two kits get identical numbers and we’ve shown one table for both. This is the kit that makes sense on a small station. Even the River 3 Plus gets you through an evening, and a kilowatt-hour class station covers about a day.

Starlink Performance

The Performance has the same published average range as the Standard, but its spec sheet also lists a DC input, so you get 12V rows here. A mid-size station covers a working day on these figures. The small one is a couple of hours.

Starlink Standard 4 X

Starlink’s average figure for this kit covers the dish, the router and the power supply together, which is how you’d actually run it. AC only, as above. For full-time use off-grid, this is the kit that pushes you toward the bigger stations or a solar setup.

Which size to get

With a Mini or Mini X, a small station like the EcoFlow RIVER 3 Plus is fine for a few hours of work in the evening. If you want the dish on all day, go for something like the EcoFlow DELTA 2 or Bluetti AC180.

With a Performance or Standard kit, skip the small stations. A mid-size one gets you through a working day, but not much more. To leave the dish on around the clock for days at a time, you’re looking at the Jackery Explorer 2000 v2 or EcoFlow DELTA Pro class, or a way to recharge every day. Our solar recharge calculator estimates how long a refill takes.
