Jackery Explorer 300 Plus vs Jackery Explorer 240
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Jackery Explorer 240 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 300 Plus holds 20% more energy (288Wh vs 240Wh), so it runs the same load proportionally longer.
- Jackery Explorer 300 Plus has 200W more surge headroom (600W vs 400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 240 is 1.7 lb lighter (6.6 lb vs 8.27 lb).
- Jackery Explorer 300 Plus uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Jackery Explorer 300 Plus is rated for 3,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Jackery Explorer 240. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
A device charger, not a power station. At 8.27 lb and 288Wh it's for phones, laptops and a CPAP — nothing with a heating element or compressor.
Best for: CPAP users and travelers who need days of small-device power in a bag.
Where it falls short:
- 300W output rules out almost every appliance
- 288Wh is a single laptop-day of capacity
A very old, very small unit still sold on price alone. The LiFePO4 Explorer 240 v2 beats it on cycles and charging for similar money.
Best for: Only if it’s markedly cheaper than the 240 v2.
Where it falls short:
- ~500 Li-ion cycles
- 200W output, no USB-C PD
