Jackery Explorer 300 Plus vs Jackery Explorer 1500 Ultra
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 $900 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 1500 Ultra holds 433% more energy (1536Wh vs 288Wh), so it runs the same load proportionally longer.
- Jackery Explorer 1500 Ultra has 3000W more surge headroom (3600W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 300 Plus is 18.2 lb lighter (8.27 lb vs 26.5 lb).
- Jackery Explorer 1500 Ultra is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Jackery Explorer 300 Plus
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
Jackery Explorer 1500 Ultra
The portability record-holder: 1536Wh at 26.5 lb, lighter than most 1kWh units. You pay $200 over the 1500 v2 for that weight saving.
Best for: Van lifers and overlanders where every pound is negotiated.
Where it falls short:
- 1800W output is lower than the cheaper 1500 v2's 2000W
- $1199 is a premium for weight alone
