Overview

The Explorer 300 Plus (US model JE-300B) is Jackery's grab-and-go compact: a 288 Wh LiFePO4 pack driving one 120 V outlet at 300 W rated (600 W surge), dual USB-C — one at 100 W — and a 12 V car socket, all at 3.75 kg. Wall charging takes a rated 2 hours; solar charging runs through the 100 W USB-C input via an 8020-to-USB-C adapter. Official sources conflict on cycle life (manual spec table: 3,000 cycles to 80%+; page FAQ: 4,000 cycles to ~70%) — the manual table value is used here with the conflict preserved. EPS support is officially confirmed with no stated switchover time. The base unit showed 'Sold Out' at check time with the newer Explorer 300 v2 also listed, so release status is recorded as unclear.

Variant note: US model JE-300B (120 V/60 Hz). 'Solar Generator 300 Plus' bundles and a 2-pack + GaN charger kit excluded; refurbished listing sold separately.

Data note: Release status unclear: the product page is live on the US site but the base variant shows 'Sold Out' / 'Notify Me When Available' with no official discontinuation notice, and the newer Explorer 300 v2 (288 Wh/300 W) is also listed as an apparent successor. CYCLE LIFE CONFLICT between official sources: manual spec table '3000 cycles to 80%+ capacity' vs page FAQ '4000 full charge cycles ... about 70% of your original capacity'; manual table value used, both preserved. acInputW null (official sources state '100V-120V~60Hz, 10A Max' with no wattage). Manual's capacity line generically says 'Lithium-ion'; the page states LiFePO4 explicitly (12.8 V nominal is consistent with LFP) — normalized to lifepo4. Waveform pure sine per page specs.

Strengths and weaknesses

Strengths

3.75 kg — genuinely one-hand portable
LiFePO4 chemistry at a size where NMC is still common
100 W USB-C input/output doubles as a solar input
Fast 2 h wall recharge
5-year warranty (3 standard + 2 via official registration)

Weaknesses

Single AC outlet at only 300 W continuous
Official sources conflict on cycle life (3,000@80% vs 4,000@~70%)
Solar limited to 100 W through the USB-C port, adapter required
Base unit 'Sold Out' at check time with a v2 successor listed — release status unclear
No expansion battery support documented
