Bottom Line

Explorer 300 v2 (JE-300C) is a 288 Wh, 300 W unit with two 120 V outlets and a stated 10 ms UPS mode; it weighs 3.7 kg.

Strengths

Practical advantages

  • Two 120 V outletsThe unit provides two 120 V / 60 Hz AC outlets, with 300 W rated output and 600 W maximum instantaneous output.
  • Cycle-life claimJackery states 4,000 cycles to at least 70% capacity for the LiFePO4 battery.
  • Charging times by modePublished times are about 1.5 h on AC, 3 h from a car socket and 3 h with a SolarSaga 200 panel.

Tradeoffs

Supported limitations

  • Solar and car-input limitsSolar is limited to one 16–28 V, 6 A panel; SolarSaga 500X and roof-mounted high-voltage solar are unsupported. Car input is 11–16 V, up to 96 W.
  • No expansion batteriesThe manufacturer states that expansion batteries are not supported.

Evidence gaps

What remains unknown

  • Maximum AC charging inputThe reviewed source gives 100–120 V, 60 Hz and 15 A maximum, plus a separate 400 W minimum input requirement, but no maximum charging wattage.
