Jackery Explorer 300 Plus vs Jackery Explorer 500
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 300 Plus costs $200 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 500 holds 80% more energy (518Wh vs 288Wh), so it runs the same load proportionally longer.
- Jackery Explorer 500 has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 300 Plus is 5.0 lb lighter (8.27 lb vs 13.3 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 500. 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 long-running compact that's now firmly dated: one AC outlet, no USB-C, Li-ion cells and a very slow recharge. Only its ubiquity keeps it around.
Best for: Light, occasional device charging when found cheap.
Where it falls short:
- ~500 cycles
- One AC outlet, no USB-C
- 7.5-hour recharge
