Anker 521 PowerHouse 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 $50 less. Whether that gap is worth closing depends on what you need to run.
- Anker 521 PowerHouse holds 7% more energy (256Wh vs 240Wh), so it runs the same load proportionally longer.
- Jackery Explorer 240 has 100W more surge headroom (400W vs 300W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 240 is 1.6 lb lighter (6.6 lb vs 8.2 lb).
- Anker 521 PowerHouse uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Anker 521 PowerHouse 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 pocket-scale LiFePO4 unit for keeping devices alive. 200W of output means it's a charger, not an appliance station.
Best for: Travelers and campers topping up phones, cameras and a laptop.
Where it falls short:
- 200W output runs devices only
- 256Wh is small
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
