Weight is the spec every roundup in this category lists once, in a table, and then never discusses. It is also, for anyone who moves the unit, the spec most likely to determine whether they keep using it. This page exists to treat it as the primary criterion rather than a footnote.
The numbers, calculated
| Unit | Weight | Capacity | Wh per lb | AC output |
|---|---|---|---|---|
| Jackery Explorer 300 v2 | About 8.2 lb | 288Wh | About 35.1 | 300W |
| EcoFlow RIVER 3 Plus | 10.4 lb | 286Wh | 27.5 | 600W |
| Jackery Explorer 1000 v2 | 23.8 lb | 1,070Wh | 45.0 | 1,500W |
| Anker SOLIX C1000 Gen 2 | 24.9 lb | 1,024Wh | 41.1 | 2,000W |
Two counter-intuitive things fall out of that table, and both change how you should shop.
Small units have worse watt-hours per pound, not better. The casing, the inverter, the display, the ports and the cooling are a roughly fixed overhead. A 288Wh unit spreads that weight over far less stored energy than a 1,070Wh unit does. The Jackery 1000 v2 carries 45Wh per pound against the RIVER 3 Plus's 27.5 — the bigger unit is dramatically more efficient by weight.
Which means 'lightest' and 'most efficient' are different questions. If your requirement is 'as little weight as possible, full stop', buy small. If it is 'the most capacity I can reasonably carry', the 1kWh class is the answer, and the 23.8 lb Jackery is where that class starts.
What each weight band actually feels like
- Under 12 lb — carried without thinking. Walk-in pitches, boats, hotel rooms, a long trail. 250-300Wh and 300-600W of output.
- 20-25 lb — one hand for fifty yards, two for two hundred. This is where 1kWh begins, and where a fridge becomes possible.
- 30-40 lb — a deliberate carry you will do once per trip. Fine from a tailgate, tiring across a campsite.
- Over 50 lb — it lives where you put it. See home backup rather than this page.
The carry-on question
People often arrive at a lightweight roundup because they want to fly with one. That does not work, and it is worth saying plainly before you spend anything: the FAA forbids lithium-ion batteries over 160 watt-hours on passenger aircraft, and the lightest unit on this page is 288Wh — nearly twice the limit. Weight is irrelevant to that rule; only the watt-hour rating counts. The full rules with TSA and FAA citations.
How to choose here
Work out your real load list first — what size do I need — then take the lightest unit that clears it. Doing it the other way round produces one of two failures: a unit too small for the job, or a unit so heavy it stays at home. The weight guide has the full reasoning, and for tent-specific advice, best power station for tent camping is the sharper page.
The picks in full
1. Best lightweight overall
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
10.4 lb with 600W of AC output and a path to 858Wh is the best combination of light-now and bigger-later available. It is not the absolute lightest unit here, but it carries twice the output of the one that is, and it is the only sub-11 lb unit that expands at all.
The compact 9.2 x 9.1 x 5.8 in footprint matters as much as the weight for a carried unit — it packs into a bag rather than displacing one. A 60-minute full recharge means a stop anywhere puts you back to full, and 220W of solar input is generous for a battery this size.
The one thing missing is documentation: EcoFlow's US product page publishes no warranty term for this model. Given 3,000 cycles to 80% is otherwise a strong rating, that omission is odd and worth confirming with a retailer.
Reasons to buy
- 10.4 lb and genuinely compact
- 600W output, 1,200W with X-Boost — double most sub-11 lb units
- Expands to 858Wh
- 60-minute full recharge; 220W solar input
- 3,000 cycles to 80% LiFePO4
Reasons to avoid
- No published warranty term on the US product page
- 27.5Wh per pound is the worst ratio on this page
- 286Wh is about 15 hours of a 12V fridge
- The expansion battery is a substantial extra outlay
Buy it if: you carry it, and you want the option of more capacity without a second unit.
Skip it if: every ounce counts. The Jackery 300 v2 is 2.2 lb lighter.
2. Lightest with real AC outlets
Jackery Explorer 300 v2
- 288Wh
- LiFePO4 (LFP)
- 300W continuous / 600W surge
- 8.2 lb
- 100W
- 4,000+ cycles
- 80% in about 1 hr
- 5 years (with registration)
About 8.2 lb is the lowest weight here, and unlike a lot of ultra-light units it still gives you two genuine AC outlets rather than USB only. 288Wh covers a weekend of phones, lights, a tablet and a laptop evening with margin, or one night of a CPAP with the humidifier off.
At roughly 35Wh per pound it is also more efficient by weight than the RIVER 3 Plus, which is a useful reminder that the lightest unit is not automatically the least efficient one. The 100W USB-C output lets a laptop charge without the inverter, which saves both energy and fan noise.
Its ceilings are the lowest here on both axes: 300W of output rules out anything that heats, and 100W of maximum solar input means a panel is a slow trickle rather than a refill. For a devices-only load list, neither matters.
Reasons to buy
- About 8.2 lb — the lightest on this page
- Roughly 35Wh per pound, better than the RIVER 3 Plus
- Two AC outlets plus 100W USB-C
- 4,000+ cycles and a published 5-year warranty
- 80% charge in about an hour
Reasons to avoid
- 300W output — nothing that heats
- 100W maximum solar input, the lowest here
- No expansion path
- Weight figure comes from retailer listings, not Jackery's spec page
Buy it if: minimum weight, devices-only load list, longest carry.
Skip it if: you might add a fridge or a fan later. There is no headroom at all.
3. Most capacity per pound
Jackery Explorer 1000 v2
- 1,070Wh
- LiFePO4 (LFP)
- 1,500W continuous / 3,000W surge
- 23.8 lb
- 400W
- 4,000 cycles to 70% capacity
- 1.7 hr wall; 1 hr emergency charge via app
- 5 years (with registration)
45Wh per pound is the best figure on this page by a clear margin — 64% better than the RIVER 3 Plus and 28% better than the next 1kWh unit. If your question is 'how much capacity can I carry', rather than 'how little can I carry', this is the answer.
23.8 lb is a real carry, but it is the lightest that a kilowatt-hour gets, and a kilowatt-hour is what a 12V fridge over two nights or a three-night CPAP trip actually needs. The foldable handle also packs flatter than rigid-handled rivals, which matters when it is going in a boot alongside everything else.
It is on this page as the upper bound of carryable rather than as a light unit. If your pitch is two hundred yards over sand, this is too much. If it is fifty yards on a path, it is 3.7 times the battery of the units above it for 2.3 times the weight.
Reasons to buy
- 45Wh per pound — the most efficient unit here by weight
- 1,070Wh: two nights of a 12V fridge, or a three-night CPAP trip
- 1,500W continuous, 3,000W surge
- Foldable handle packs flat
- Below 22 dB in silent mode; 5-year warranty
Reasons to avoid
- 23.8 lb is the upper limit of a comfortable carry
- 400W solar input is modest for the capacity
- Two AC outlets
- Cycle rating quoted to 70%, not 80%
Buy it if: you want maximum capacity that one person can still carry a short distance.
Skip it if: the carry is long or repeated. Under 12 lb is a different experience.
4. Most output per pound
Anker SOLIX C1000 Gen 2
- 1,024Wh
- LiFePO4 (InfiniPower LFP)
- 2,000W continuous / 3,000W surge
- 24.9 lb
- 600W
- 80% capacity after 4,000 cycles
- Full in 49 min (UltraFast, 1,600W max input)
- 5 years
2,000W of continuous output at 24.9 lb is 80 watts of capability per pound — nothing else here is close. If what you need to carry is the ability to run a high-draw appliance somewhere there is no outlet, rather than a large battery, this is the most efficient way to do it.
The 49-minute full recharge compounds that: a light-ish unit that refills in under an hour behaves, in practice, like a bigger one, because you can top it up at any stop rather than rationing it across a trip.
It is 1.1 lb heavier than the Jackery for 46Wh less battery, so on pure capacity-per-pound it loses. It wins on what that capacity can do, and which of those matters is entirely down to your appliance list.
Reasons to buy
- 2,000W continuous, 3,000W peak at 24.9 lb
- 49-minute full recharge — fastest here
- 600W solar input with a 60V ceiling
- 10 ms UPS switchover
- 80% after 4,000 cycles; 5-year warranty
Reasons to avoid
- 41.1Wh per pound, behind the Jackery's 45.0
- Not expandable
- Two AC outlets
- The output advantage is irrelevant on a devices-only load list
Buy it if: you need high wattage somewhere remote and want to carry as little as possible to get it.
Skip it if: your loads are small. You are carrying inverter capacity you never use.
