Starlink Runtime Calculator

Daily energy (Wh) ≈ average watts × hours of use per day. Enter your own measured consumption if you have it, or pick a clearly labeled example profile, set how many days you need to run without recharge, and the calculator shows the capacity needed and which catalog products can deliver it.

Off-grid travelers, remote workers, and emergency-preparedness planners who need to size battery capacity for a Starlink kit, with or without solar recharge.

Recommended minimum capacity

1,694 Wh

= (1,200 Wh/day × 1 day) ÷ 85% usable × (1 + 20% reserve)

Solar contributes an estimated 0 Wh/day, leaving a daily deficit of 1,200 Wh that the battery must supply. This is a planning estimate, not a guarantee of actual sun conditions.

Wh per day: 1,200 Wh
Daily deficit after solar: 1,200 Wh
Continuous output needed: 50 W

Why your real result may differ

These figures are planning estimates from the inputs and assumptions above — not a lab measurement. Your real result can vary with:

Temperature — cold reduces usable battery capacity; heat can trigger throttling
Battery age and condition — capacity fades gradually with cycles and time
Inverter efficiency — some energy is always lost converting DC to AC
Variable appliance draw — most appliances don't pull a constant wattage
Startup/surge power — a motor's brief startup spike can exceed its running watts
Appliance settings — e.g. humidifier, fan speed, or temperature setting
Conversion losses beyond the modeled efficiency assumption
Real solar conditions — actual panel output is usually well below its rated watts
The safety reserve is a margin for error, not a guarantee

How this is calculated

Recommended Power Stations

Compare your shortlist →

Every product in the catalog is classified against your requirement using the same engine as the Power Calculator: first compatibility (does it meet every hard requirement), then how proportionate it is to your need. Units that fail a hard requirement are shown as Not Suitable with the reason, rather than hidden — and units far larger than you need are labeled Oversized rather than presented as a top pick.

No product in the current catalog is a proportionate match for this requirement. Larger, oversized alternatives are listed below.

Oversized alternatives — larger than you need (18)

These fully meet your requirement but carry much more capacity or output than your calculation needs. They can still make sense for future growth, but they are not the proportionate pick.

Why these results?

Recommendations are deterministic: your required continuous output, capacity (with reserve) and estimated surge are compared against each unit’s manufacturer-published specs, then your stated hard requirements are applied. Nothing here is sponsored, and no score is invented to rank a product.

Formula

Daily energy (Wh) = average watts × hours/day (24 if continuous). Daily deficit after solar = max(0, daily energy − daily solar Wh). Recommended minimum capacity (Wh) = (daily deficit × days) ÷ usable efficiency × (1 + reserve fraction).

Why Starlink power draw isn't a single number

Average consumption differs by hardware generation and dish size, and rises substantially when the dish actively heats itself to melt snow or ice — commonly reported as roughly doubling average draw during active heating. Ambient temperature, dish angle adjustments, and duty cycle also affect the real average.

The example profiles below are clearly labeled starting points, not a specification for any particular Starlink hardware revision. Entering your own measured average — from a plug-in energy meter on the power supply — gives the most reliable number.

Continuous operation vs. scheduled use

Running Starlink continuously (24 hours/day) uses far more daily energy than powering it on only when needed. If your use case allows scheduled operation — powering on for work hours only, for example — entering realistic hours/day rather than defaulting to continuous can substantially reduce the capacity you actually need.

Common mistakes

Assuming a single average-watts figure applies regardless of weather, when active snow-melt heating can roughly double consumption.
Defaulting to continuous 24-hour operation when the actual use case is scheduled hours per day.
Ignoring router or additional networking equipment power draw layered on top of the dish itself.
Treating an AC/DC efficiency assumption as a guarantee rather than a starting point to adjust for your actual cabling.

FAQ

Does cold weather really double Starlink's power use?

Active snow-melt heating draws substantially more power than normal operation — commonly cited as roughly double the typical average — because the dish is actively warming itself. Use the heating-active profile below (or your own measured figure in cold conditions) for a more realistic estimate in winter conditions.

Can I run Starlink directly on DC instead of through an inverter?

Some setups use a DC-to-DC adapter to bypass a power station's AC inverter, which avoids inverter conversion losses — check compatibility with your specific Starlink hardware and cabling before relying on this, and use the AC/DC toggle here only as a starting assumption for the efficiency slider.

How much does the router add?

It depends on the router — anywhere from a few watts for a low-power travel router to 15-20 W or more for a full-featured unit. Enter your router's own rating label figure in the "Router / additional equipment" field rather than assuming Starlink's own kit already includes it.
