A satellite internet terminal is an unusual load for a portable battery. It is not large — most sit somewhere in the region of a laptop's draw — but it is continuous in a way that almost nothing else in this category is. A fridge cycles. A laptop gets closed. A terminal runs every minute you want internet, which if you are working remotely is every minute of the day.
That changes the sizing conversation entirely. Output rating is irrelevant — any unit here supplies the wattage. The question is purely how many hours of continuous draw your capacity buys, and whether your recharge covers the daily total.
The arithmetic
Run that for a couple of draw figures and the shape of the problem becomes obvious.
| Capacity | At 45W | At 60W | At 90W |
|---|---|---|---|
| 286Wh | About 5 hours | About 4 hours | About 2.5 hours |
| 1,024Wh | About 18 hours | About 13.5 hours | About 9 hours |
| 1,152Wh | About 20 hours | About 15 hours | About 10 hours |
| 2,048Wh | About 36 hours | About 27 hours | About 18 hours |
Why solar input matters more than capacity here
Look at that table and the conclusion is uncomfortable: even a 2kWh unit is barely over a day of continuous terminal operation, and that is before the laptop you are presumably using the internet on. Buying capacity does not solve a continuous load; it only postpones it.
What solves it is daily harvest exceeding daily draw. A terminal at 60W consumes about 1,440Wh over 24 hours. A 400W panel array on a good day returns 1,400-1,800Wh. That is the actual answer: enough solar to cover the day, with battery as the overnight buffer. How much solar input you need works through the sizing.
Two practical savings
Turn it off when you are not using it. Obvious, routinely ignored, and worth more than any hardware choice. A terminal running 10 hours instead of 24 cuts consumption by nearly 60%.
Run it on DC if your hardware supports it. As with a CPAP, passing through the inverter costs 10-15%. If there is a DC option for your terminal, use it and keep the inverter switched off — which also removes the inverter's own idle draw.
The picks in full
1. Best for keeping a terminal online off-grid
EcoFlow DELTA 3 Plus
- 1,024Wh
- LFP (LiFePO4)
- 1,800W continuous / 3,600W surge
- 27.6 lb
- 1000W
- 4,000 cycles to 80%+ capacity
- Full in 56 min (1,500W AC input)
- 5 years
Up to 1,000W of solar input across two MPPT channels is the specification that turns this from a one-day battery into an indefinite supply. A terminal at 60W needs about 1,440Wh a day; a properly sized array into a unit that will accept it covers that with margin on any decent day.
1,024Wh of battery is roughly 13-15 hours at a 60W draw, which is an overnight buffer rather than a supply — and that is the correct way to think about it. Expansion to 5kWh means you can buy more buffer for a bad-weather week without changing the head unit.
1,800W of output is far more than a terminal needs, which is the point: you get the internet and the laptop and the kettle from the same box.
Reasons to buy
- Up to 1,000W solar across two MPPT inputs
- Expandable to 5kWh for bad-weather buffer
- 1,024Wh — about 13-15 hours at 60W draw
- IP65 rated, which matters for an outdoor setup
- 56-minute AC recharge; 4,000 cycles to 80%+
Reasons to avoid
- The 1,000W figure requires two panel arrays
- 27.6 lb and a large footprint
- Base capacity alone is under a full day of continuous use
- Expansion batteries are a large extra cost
Buy it if: you are working remotely off-grid and the terminal runs most of the day.
Skip it if: you use the terminal a few hours in the evening. A smaller unit covers that.
2. Most hours per charge in the 1kWh class
BLUETTI AC180
- 1,152Wh
- LiFePO4
- 1,800W continuous / 2,700W surge
- 35.27 lb
- 500W
- 3,500+ cycles to 80% original capacity
- 1.3-1.8 hr full (1,440W max AC input)
- 5 years
1,152Wh is the largest battery in the class, which at a 60W terminal draw is roughly 15 hours — the most continuous operation you will get from a single 1kWh-class unit.
Four AC outlets means the terminal, a laptop, a phone charger and a light all run without a strip, which for a remote-work setup is exactly the connector layout you want. The 20 ms UPS switchover also means you can leave it inline at home and never drop a call during a brownout.
500W of solar input is the limitation. For a day-in-day-out continuous load, that is enough to slow the drain rather than reverse it, so this is the better choice if you have regular access to an outlet and the worse one if you do not.
Reasons to buy
- 1,152Wh — the most hours per charge in its class
- Four AC outlets for a full remote-work setup
- 20 ms UPS switchover
- 3,500+ cycles to 80%; 5-year warranty
- 1,440W AC input, full in 1.3-1.8 hours
Reasons to avoid
- 500W solar input is thin for a continuous daily load
- 35.27 lb
- Not expandable
- Still only about 15 hours at 60W — not a two-day unit
Buy it if: you have regular mains access and want the longest single-charge runtime.
Skip it if: you are genuinely off-grid for days. Solar input matters more than capacity.
3. Best for multi-day remote work
EcoFlow DELTA 2 Max
- 2,048Wh
- LFP (LiFePO4)
- 2,400W continuous
- 1000W
- 3,000+ cycles
- 2.3 hr
- 5 years
2,048Wh is roughly 27 hours at a 60W terminal draw — the first unit here that covers more than one full day of continuous operation with something left for a laptop.
It also takes up to 1,000W of solar at 99% MPPT efficiency and expands from 2kWh to 6kWh, so it is the unit that scales into a genuinely self-sufficient remote-work setup rather than a long weekend.
EcoFlow does not publish a weight or a surge figure for it, and we have not filled those in from elsewhere. For this use case neither is likely to decide anything — the unit is going to sit next to a desk, wherever the desk happens to be.
Reasons to buy
- 2,048Wh — about 27 hours at a 60W draw
- Expandable from 2kWh to 6kWh
- Up to 1,000W solar input, 99% MPPT efficiency
- 2,400W continuous, 3,400W with X-Boost
- 3,000+ cycles; 5-year warranty
Reasons to avoid
- EcoFlow publishes no weight or surge figure
- Substantially more expensive than the 1kWh units
- Large and heavy enough to be a fixture, not a carry
- Overkill if the terminal runs a few hours a day
Buy it if: remote work where losing internet costs you money and you want real margin.
Skip it if: the terminal is for evenings and weekends.
4. Best for a few hours a day
EcoFlow RIVER 3 Plus
- 286Wh
- LiFePO4
- 600W continuous / 1,200W surge
- 10.4 lb
- 220W
- 3,000 cycles to 80% capacity
- 0-100% in 60 min
- Not published on the US product page
Plenty of people run a terminal for a few hours in the evening rather than all day, and for that a 10.4 lb unit is entirely sufficient. 286Wh at a 60W draw is about four hours — an evening of streaming, calls or browsing.
It is also the only unit here you would carry to where the sky is clear, which for a satellite terminal is occasionally the whole problem. A dish needs a view, and the view is not always next to the vehicle.
220W of solar input recharges it fully in a good day, so a light panel plus this unit is a workable evening-internet setup that weighs almost nothing.
Reasons to buy
- 10.4 lb — carry it to where the sky is clear
- About 4 hours at a 60W terminal draw
- 220W solar input refills it in a day
- Expands to 858Wh for longer sessions
- 60-minute AC recharge
Reasons to avoid
- 286Wh is an evening, not a day
- No published warranty term on EcoFlow's US page
- Adding the expansion battery costs nearly as much as a bigger unit
- Not suitable if the terminal runs continuously
Buy it if: evening internet, and you want the dish somewhere the vehicle is not.
Skip it if: you are working online all day. This is four hours.
