Jackery Explorer 300 Plus vs Anker 757 PowerHouse
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 $700 less. Whether that gap is worth closing depends on what you need to run.
- Anker 757 PowerHouse holds 327% more energy (1229Wh vs 288Wh), so it runs the same load proportionally longer.
- Anker 757 PowerHouse has 1800W more surge headroom (2400W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 300 Plus is 35.6 lb lighter (8.27 lb vs 43.9 lb).
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
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
Anker's older flagship, now a discount play. Solid and durable, but heavy for its capacity and outclassed on charge speed by the newer C-series.
Best for: Buyers who find it discounted below the newer Anker C1000.
Where it falls short:
- 43.9 lb for 1.2kWh is heavy
- 300W solar input is low
- Outclassed by the newer C1000
