Where it makes sense
Small charging and lighting loads that stay within the energy and output limits.
The main trade-off
Easy to carry, but its 288 Wh nameplate capacity leaves much less energy headroom than either larger model.
Know the limits
- 288 Wh is rated battery energy, not measured energy delivered to your devices.
- The two AC outlets share 300 W; the rating is not 300 W for each outlet at the same time.
- A 600 W advertised peak does not verify that a particular compressor or motor will start.
- Jackery lists no expansion-battery support for this model.
- This is JE-300C / Explorer 300 v2, not JE-300B / Explorer 300 Plus or the older 293 Wh Explorer 300.
Startup is a separate check. Jackery lists a 600 W surge peak, but the checked sources do not specify its duration or motor-start conditions. We do not use this figure to confirm a starting load.
How long for a steady load?
Estimate one constant AC load from the rated battery energy. This is a mathematical scenario, not a measured runtime or a startup check.
Use a constant load of at least 0.01 W, not a cycling appliance’s maximum watts.
Enter a load to calculate an estimate.
Default illustrative assumptions: 90% usable charge range, 85% conversion efficiency, 3 W output-equivalent idle draw. A saved plan supplies your own assumptions instead.
Formula: rated Wh × charge range × efficiency ÷ (load W + idle W). Excludes recharging, expansion batteries, temperature effects and age. Always check continuous output and relevant startup requirements separately.
Connections and shared limits
- 2 × 120 V AC outlets; 300 W total continuous
- 1 × USB-C input/output, up to 100 W
- 1 × USB-C output, up to 15 W
- 1 × USB-A output, up to 15 W
- 1 × 12 V car-style output, up to 10 A
Match your actual plugs, cable ratings, voltage and device instructions. The finder’s AC estimate does not assess USB-C charging negotiation or DC-path efficiency.

- LiFePO₄ (LFP)
- Dimensions, with axis order
- 23.1 × 15.3 × 16.8 cm (W × D × H; manufacturer dimensions)
Solar charging: the input limits
Up to 100 W · 16–28 V · 6 A maximum
One DC8020 solar input: 16–28 V, 6 A and 100 W maximum. The manual requires panel open-circuit voltage within this range. The separate 11–16 V / 96 W range is for 12 V vehicle charging; 24 V vehicle charging is not supported.
These are manufacturer input ceilings. They do not predict solar harvest, charge time, connector compatibility or panel suitability in your conditions. Solar energy is not credited in the finder.
