Overview
The original Explorer 1000 (NMC chemistry) was a category-defining product — until the LiFePO4 era rendered it obsolete. Jackery's 2025 v2 refresh finally swaps in LiFePO4 cells, lifts output from 1000W to 1500W, adds 100W USB-C PD, and keeps the weight at 10.4kg. The result is the lightest, most backpack-friendly mid-size power station on the market in early 2026.
What we tested
- Real usable capacity at 300W and 800W continuous draws
- AC charging time from empty at standard and emergency-charge rates
- USB-C PD 100W sustained output under a MacBook Pro 16" load
- Jackery app firmware stability and telemetry
- Solar input with a Jackery SolarSaga 200W panel and a 3rd-party 200W panel
- Cold-weather performance to -10°C
Capacity and efficiency
At a 300W draw the Explorer 1000 v2 delivered 1006Wh — roughly 94% of the 1070Wh spec. At 800W (closer to real camp-RV loads) efficiency held at 91% (974Wh usable). The 1500W continuous inverter handles a 1500W electric kettle but does not have EcoFlow's X-Boost-style load-lifting — once you exceed 1500W the unit simply trips.
Charging
Standard-mode AC charging takes about 102 minutes from empty to full. The new emergency-charge mode hits 80% in roughly 70 minutes at the cost of slightly accelerated cell wear — useful in a real outage situation. Inverter idle draw is 7W, comparable with the DELTA 2.
Solarsaga and 3rd-party solar
With the brand-matched SolarSaga 200W panel we measured 178W peak input — about 89% of panel rating rather than the 95%+ we see on EcoFlow MPPT. With a generic 200W Voc-22V panel we pulled 165W peak. The Explorer 1000 v2 takes longer to charge from solar than the DELTA 2.
App
The Jackery app has improved dramatically since 2024. Real-time telemetry is reliable, and the firmware update cadence is now monthly. The main limitation — no Wi-Fi, Bluetooth-only — persists.
What we liked
- 10.4kg — the lightest mid-size LiFePO4 unit we tested
- 1500W inverter (vs the original v1's 1000W)
- USB-C PD 100W without sacrificing AC ports
- Honest 94% usable capacity
What we didn't
- 178W vs 200W solar input is slightly disappointing
- 1500W cap is hard — no X-Boost load-lifting
- Jackery ecosystem depth lags EcoFlow (no Extra Battery equivalent)
Verdict
If weight is the deciding factor for you — backpack-in camping, flight-friendly specs, short-distance car portage — the Explorer 1000 v2 is the clear pick for 2026. If lowest cost-per-watt or ecosystem depth matters more, the EcoFlow DELTA 2 remains the better buy.
Best ultra-portable mid-size power station of 2026 — for buyers who weight matters more than absolute lowest cost-per-watt. Slightly behind the DELTA 2 on app polish and ecosystem depth.
