The only ratio that matters
At home, a power station's weight is irrelevant. At a campsite it is the whole experience — the difference between a one-hand carry from the tailgate and a trip you resent.
So the useful figure is not capacity and not weight but the two divided: usable watt-hours per pound. Both halves have been independently measured for every unit here.
| Unit | Measured usable | Measured weight | Usable Wh per lb | Camp fridge |
|---|---|---|---|---|
| Jackery Explorer 2000 v2 Best 2-night | 1,710 Wh | 38.9 lb | 44.0 | 38 h 00 |
| Jackery Explorer 1000 v2 Winner | 910 Wh | 24.4 lb | 37.3 | 20 h 13 |

| EcoFlow River 2 Pro | 620 Wh | 18.4 lb | 33.7 | 13 h 47 |
| EcoFlow Delta 3 | 870 Wh | 28.1 lb | 31.0 | 19 h 20 |

Fridge runtimes assume a 12 V compressor fridge averaging 45 W — assumptions here.
1 · Jackery Explorer 1000 v2 — one night, one hand
1:1
Jackery Explorer 1000 v2
Calculated, not observed: 910 Wh measured usable ÷ 45 W average draw; solar from 150 W effective input (2×100 W derated to 75%). Assumptions.
usable Wh
The Explorer 1000 v2 delivers more usable energy than any other 1 kWh unit — 910 Wh, against 890 for the Anker and Bluetti and 870 for the EcoFlow — while weighing the least of the four at a measured 24.4 lb.[1]
Twenty hours of camp fridge covers a night comfortably with margin for phone charging and lights. It recharges in a measured 1 h 35, which matches Jackery's own claim.[1]
The compromises are real but mostly do not bite while camping: 1,500 W output (fine unless you brought an induction burner), a 400 W solar ceiling (fine on two panels, limiting on four), and cycles rated to 70% rather than 80% (irrelevant at thirty cycles a year).[3]
2 · Jackery Explorer 2000 v2 — two nights, still liftable
1:1
Jackery Explorer 2000 v2
Calculated, not observed: 1710 Wh measured usable ÷ 45 W average draw; solar from 150 W effective input (2×100 W derated to 75%). Assumptions.
usable Wh
At 1,710 Wh measured usable and 38.9 lb measured, this is 44 usable watt-hours per pound — the best ratio of any unit on this site, and better than every 1 kWh box on the list.[2]
That is the counter-intuitive part of carrying batteries: the bigger unit is the more efficient thing to lift. Thirty-eight hours of camp fridge covers a full weekend without solar, which is the trip most 1 kWh units cannot quite manage.
Thirty-nine pounds is still thirty-nine pounds. It is a two-hand lift into a truck bed rather than a one-hand carry to a pitch, and its 400 W solar ceiling on a 2 kWh pack means solar recharging is slow going.[4]
3 · Anker SOLIX C1000 Gen 2 — the better all-rounder
1:1
Anker SOLIX C1000 Gen 2
Calculated, not observed: 890 Wh measured usable ÷ 45 W average draw; solar from 150 W effective input (2×100 W derated to 75%). Assumptions.
usable Wh
Nine tenths of a pound heavier than the Jackery and twenty watt-hours lighter in capacity — a difference you will never notice at a campsite. In exchange you get 2,000 W of output instead of 1,500 W, a 56-minute recharge instead of 1 h 35, a 600 W solar ceiling instead of 400 W, and cycles rated to 80% rather than 70%.[5][6]
If the carry is short — car to pitch — this is the better unit and it costs less. The Jackery wins this list on the ratio; the Anker wins on everything you do once you have put it down.
4 · Bluetti Elite 100 V2 — if you recharge from the sun
1:1
Bluetti Elite 100 V2
Calculated, not observed: 890 Wh measured usable ÷ 45 W average draw; solar from 150 W effective input (2×100 W derated to 75%). Assumptions.
usable Wh
Identical measured capacity to the Anker at 890 Wh, and the same broad weight.[7] The reason to choose it is a 1,000 W solar ceiling — two and a half times the Jackery's — which matters the moment you go beyond a starter pair of panels.[8]
For trips longer than a weekend where the sun does the refilling, that ceiling is worth more than the small differences elsewhere.
The small ones, and an honest warning
The EcoFlow River 2 Pro at 18.4 lb and the Anker SOLIX C300 at 9.1 lb are the genuinely light options.[10][11]
The River 2 Pro manages about fourteen hours of fridge, which covers a night — though it returned only 81% of its rating, the weakest efficiency of anything measured here.[10]
What actually drains it at a campsite
| Load | Draw | Hours on 910 Wh |
|---|---|---|
| 12 V camp fridge | 45 W average | 20 h 13 |
| LED lights and phone charging | 25 W | 36 h 24 |
| Laptop | 60 W | 15 h 10 |
| Electric blanket | 100 W | 9 h 06 |
| Coffee maker | 900 W | 1 h 01 |
| Induction burner | 1,300 W | 0 h 42 |
The pattern is consistent across every unit in this class: refrigeration and electronics are all day, anything that makes heat is minutes. Cook on gas.
FAQ
What size power station do I need for camping?
For one night with a 12 V fridge, lights and phones, roughly 500–600 usable watt-hours. For two nights without solar, about 1,200. Both assume you are not cooking electrically — if you are, double it and then some.
Which power station has the best weight-to-capacity ratio?
The Jackery Explorer 2000 v2 at 44 usable watt-hours per pound, followed by the Jackery Explorer 1000 v2 at 37.3. Both figures use independently measured weight and independently measured usable capacity.[2][1]
Can I run a camp fridge all weekend on one charge?
On a 1 kWh unit, roughly 20 hours — so one night comfortably, two nights only with solar topping up. On a 2 kWh unit, about 38 hours, which covers a full weekend.
Is the Anker SOLIX C300 enough for camping?
Only for devices. Its 230 measured usable watt-hours run a camp fridge for about five hours — not a night.[11] As a nine-pound box for phones, a laptop and lights it is very good.
Take the Jackery, unless the carry is short
On the ratio that decides camping, the Jackery Explorer 1000 v2 wins its class: the most usable watt-hours of any 1 kWh unit, in the lightest box.
But be honest about your carry. If it goes from the tailgate to a pitch twenty feet away, the Anker SOLIX C1000 Gen 2 is the better unit for less money — more output, faster recharge, more solar input, a stronger cycle rating — and the nine-tenths of a pound is meaningless.
For two nights, the Jackery Explorer 2000 v2 carries better than anything else here. For solar-led trips, the Bluetti Elite 100 V2. And do not buy the C300 to keep food cold — it will not.
