Anker 521 PowerHouse costs $750 less. Whether that gap is worth closing depends on what you need to run.

- Anker 521 PowerHouse is 29.3 lb lighter (8.2 lb vs 37.5 lb).
- Jackery Explorer 1500 v2 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Jackery Explorer 1500 v2
2000W output and 4000W surge at $999 makes this one of the better value picks for actual home backup, not just camping.
Best for: First-time home-backup buyers who need real surge on a budget.
Where it falls short:
- 1536Wh means about a day of fridge-plus-devices
- Not expandable
Anker 521 PowerHouse

Best for: Travelers and campers topping up phones, cameras and a laptop.
Where it falls short:
- 200W output runs devices only
- 256Wh is small
