What it can run
Same sourced device assumptions used by our calculators, applied to this model's usable AC energy. Actual runtime varies with load, temperature, and standby draw.
| Device | Estimated runtime | Sourced assumption |
|---|---|---|
| CPAP (humidifier off) | about 3.0 nights | 9 W · |
| CPAP (heated humidifier on) | about 0.5 nights | 56 W · |
| Refrigerator (full-size) | about 3.5 hours | 180 W × 35% duty cycle · |
| Wi-Fi router + modem | about 12 hours | 18 W · |
| Laptop (65W charger) | about 6.7 hours | 65 W × 50% duty cycle · |
| Phone (one full charge) | about 10 full charges | 20 W · |

How this score is computed
The BatteryRank score is computed from sourced data with a published formula — ranked by data, not lab testing. Seven sub-scores blend into a 0–100 composite, grouped into four buyer pillars. Price is deliberately not a scoring input: prices move daily, so value intelligence lives in the price section above, judged against this model's own history.
| Pillar | Built from |
|---|---|
| Power | Capacity & expansion + Output & versatility |
| Trust | Trust & reliability + Durability & longevity |
| Charging | Charging & solar |
| Livability | Portability + Quiet / livability |
Scores are cohort-relative — each model is ranked against others in its size class. Missing inputs renormalize out rather than scoring zero (a model is never penalized for a spec nobody in its class publishes), and any figure resting on a documented estimate is tagged est.

Energy available from the battery before output-conversion losses. AC-delivered capacity is shown separately in Capacity Truth.
How many full charge-and-drain cycles before the battery drops to its rated threshold (shown alongside — brands rate to different thresholds, so never compare bare cycle counts).
The type of battery cell. LiFePO4 (LFP) cells last far more cycles and are more thermally stable than older lithium-ion (NMC) cells.
The battery's nameplate energy capacity — the headline number on the box. Battery-side usable and AC-delivered capacity are shown separately.
The remaining-capacity level the cycle rating is measured to. 3,000 cycles to 80% is a stronger battery than 3,000 cycles to 70% — always read the two numbers together.

What reviewers & owners report
Named outlets and marketplaces, each rating credited where it was published.
Brand reputation: Sub-$250 entry LFP unit (256Wh/300W), 7.7lb. Solar needs DC8020->USB-C adapter (not included). Small enough that reviews are sparse; brand-level Jackery signals apply.

Quick answers
Each answer restates a sourced figure from elsewhere on this page — nothing new, nothing guessed.
- How much does the Jackery Explorer 240 v2 weigh?
- 3.5 kg (7.7 lb), manufacturer-claimed, without accessories.
- How much capacity does the Jackery Explorer 240 v2 deliver through an AC outlet?
- About 218 Wh of the rated 256 Wh reaches an AC outlet from a full charge — an estimate after our published 15% inverter-loss constant (marked est. on this page).
- How long does the Jackery Explorer 240 v2 take to charge?
- 1 h from a wall outlet, 0 to 100%, manufacturer-claimed. Fast-charge modes and solar input differ — see the charging specs on this page.
- How many watts can the Jackery Explorer 240 v2 output?
- 300 W continuous AC output and 500 W surge output, manufacturer-claimed. Appliance startup demand must stay within the relevant limit.
- What is the cycle-life rating of the Jackery Explorer 240 v2?
- 3,000 cycles to 70% remaining capacity, manufacturer-claimed. A cycle rating is not a calendar-life guarantee.
- Can the Jackery Explorer 240 v2 work as a UPS?
- Its manufacturer-claimed transfer time is 20 ms. Confirm that your connected equipment tolerates that transfer time; this is not the same as a zero-transfer online UPS.
