The Explorer 1000 v2 is the one to carry. It delivers more absolute energy than either 1,024 Wh rival while weighing less than both, which makes it the best carry ratio in its class. Three specification decisions stop it winning outright.
What the measurement says
OutdoorGearLab measured 910 watt-hours delivered from a rated 1,070 Wh — 85%.[1]
That efficiency is the joint-lowest of the four measured 1 kWh units. But because Jackery rates this pack at 1,070 Wh rather than the class-standard 1,024 Wh, it still hands over more actual energy than anything else in the class — 910 Wh against 890 for the Anker and Bluetti, and 870 for the EcoFlow.[2][3][4]
What 910 watt-hours runs
Calculated from measured capacity — assumptions here.
| Load | Draw | Calculated runtime |
|---|---|---|
| 12 V camp fridge | 45 W average | 20 h 13 |
| CPAP, humidifier off | 35 W | 26 h 00 |
| Full-size household fridge | 150 W at 35% duty | 17 h 20 |
| Laptop and phone charging | 90 W | 10 h 07 |
| Microwave | 900 W | 1 h 01 |
Note what is missing from that list. At 1,500 W continuous this is the lowest-output unit in its class, and a 1,500 W kettle sits exactly on the ceiling.[5] The Anker's 2,000 W gives you headroom this does not.
Carry weight — the actual argument
24.4 lb measured, against a claimed 23.8.[1][5] That is the lightest of the four, and combined with the largest usable capacity it produces the best energy density in the class:
| Unit | Usable Wh | Measured weight | Usable Wh per lb |
|---|---|---|---|
| Jackery Explorer 1000 v2 | 910 Wh | 24.4 lb | 37.3 |
| Bluetti Elite 100 V2 | 890 Wh | 25.3 lb | 35.2 |
| Anker SOLIX C1000 Gen 2 | 890 Wh | 25.2 lb | 35.3 |
| EcoFlow Delta 3 | 870 Wh | 28.1 lb | 31.0 |
Four pounds separates the Jackery from the EcoFlow. Over a hundred yards from a car to a campsite, that is the whole review.
Recharge
Measured at 1 hour 35 minutes, against Jackery's own 1.58-hour specification — a claim that measurement essentially confirmed.[1][5] Jackery's separate marketing claim of a one-hour "Emergency Charge" is a different mode and not what was measured.
Solar is the weak point, and it is a real one. 400 W maximum input is the lowest ceiling in the class — against 500 W for the EcoFlow, 600 W for the Anker and 1,000 W for the Bluetti.[5]
The cycle rating deserves a closer look
Jackery advertises 4,000 cycles, the same headline as Anker and EcoFlow. The retention figure differs, and it is not prominent.
Jackery rates its 4,000 cycles to 70% of original capacity.[5] Anker and EcoFlow rate theirs to 80%.[7][8]
Those are the rated retention figures applied to each unit's rating. The same headline number is describing a materially weaker promise — and the gap grows over the life of the pack, exactly when you are least able to do anything about it.
The five-year warranty is also conditional: it is three years as standard, extended to five only if you buy direct from Jackery.[5]
Where it falls short
- 400 W solar ceiling, the lowest here.[5]
- 1,500 W output, also the lowest.[5]
- Cycles rated to 70%, not 80%.[5]
- Not expandable, unlike the EcoFlow Delta 3.[8]
- Noise is a claim. Jackery's US site says 30 dB; a Jackery UK blog post claims under 22 dB. No independent laboratory has measured it. Two figures from the same manufacturer is a reason to trust neither without a third-party test.

FAQ
How long does the Jackery Explorer 1000 v2 run a fridge?
About 20 hours 13 minutes for a 12 V camp fridge averaging 45 W, or about 17 hours 20 minutes for a full-size household fridge at 150 W and a 35% duty cycle. Both calculated from the independently measured 910 Wh usable capacity.
Is the Explorer 1000 v2 better than the Anker SOLIX C1000 Gen 2?
It carries better — more usable watt-hours in a lighter box. The Anker scores higher overall on more output, more solar input, a stronger cycle rating and a lower price per usable watt-hour.[2][7]
What does "4,000 cycles" actually mean here?
That after 4,000 full charge-discharge cycles the pack should still hold 70% of its original capacity. Note the 70%: most competitors rate the same headline cycle count to 80%, which is a stronger promise.[5]
Can it run a 1,500 W kettle?
It is rated for exactly 1,500 W continuous with a 3,000 W surge, so a 1,500 W kettle sits on the limit.[5] It would also empty the unit in about 35 minutes. If you want margin, the Anker's 2,000 W is the better choice.
Do I get the five-year warranty on Amazon?
No. Jackery's five-year cover is three years as standard plus two more only when buying direct from jackery.com.[5]
The one to carry, if you recharge from a wall
The Explorer 1000 v2 wins the argument that matters if you actually move the thing: the most usable watt-hours in the class, in the lightest box, at 37 watt-hours per pound.
It loses on everything that matters if you do not. The lowest solar ceiling here, the lowest output, a cycle rating to 70% rather than 80%, and no expansion path.
So: buy it for car camping, hiking a short distance from a trailhead, or anywhere the carry is the constraint and a wall socket does the refilling. Buy the Anker SOLIX C1000 Gen 2 if it mostly sits still, and the Bluetti Elite 100 V2 if the sun is your grid.
