This is a close one — both are our top-tier 1,000Wh picks, both use a long-lived 4,000-cycle LiFePO4 battery, and both weigh about 24 lbs. They differ mainly in output and ecosystem.

The Anker has more muscle. 2,000W output (3,000W surge) versus the Jackery's 1,500W (3,000W surge) gives it more headroom to run high-wattage appliances and stack devices — useful if you'll run a fridge plus other loads (see Surge Watts vs Running Watts). It also recharges faster (49 vs 60 minutes) and takes more solar (600W vs 400W), so it tops up quicker both on the wall and off-grid.

The Jackery wins on simplicity. It's marginally lighter, and Jackery's retail presence (Costco, Target) makes returns and warranty claims easier than online-first brands — a real consideration for a several-hundred-dollar purchase you might need to service.
