Keep the fridge, router and CPAP running when the grid goes down.
For outages, look for a built‑in UPS (switchover of 20 ms or less), at least 1,000 Wh and LiFePO4 cells that tolerate sitting fully charged for months.
A rolling home battery: 4 kWh, 4,000 W at 120/240 V, expandable to 48 kWh. It can run a well pump or central AC and replaces a gas generator.
The all‑rounder: 1 kWh of LiFePO4, six AC outlets and the only model here you can grow to 5 kWh with extra batteries.
The most powerful and fastest‑charging 1 kWh unit here: 2,000 W continuous and a full tank in 49 minutes, in a smaller, lighter body than its predecessor.
3 kWh with wheels at a much lower price per kWh than most rivals. 3,600 W through its RV port, expandable to 24 kWh, and two units can pair for 240 V.
The most output in the 1 kWh class (2,600 W), 80% in 37 minutes and room to grow past 11 kWh, often at a price below rivals.
The strongest 2 kWh option here: 2,600 W, 1,000 W of solar input and a 6,000‑cycle battery rated for 17 years, at under $1,000.
Accepts up to 1,000 W of solar, double most rivals, in the most compact body of the group. The pick if your panels do the charging.
3,000 W, 1,800 W of solar input and 15 ports in a near‑silent 48.5 lb box, expandable to 22.5 kWh.
EcoFlow’s DELTA performance at a budget price: 1 kWh, 1,800 W and a full recharge in under an hour. You give up extra outlets and expansion.
Two kilowatt‑hours in a 39.5 lb body, 41% lighter than typical 2 kWh LiFePO4 units, with Jackery’s simple controls and a built‑in light.
The lightest unit here with the most capacity: 1,070 Wh in 23.8 lb, a fold‑down handle and near‑silent charging. Fewer ports and 1,500 W are the trade‑offs.
A proven, well‑reviewed workhorse: 1,152 Wh, 11 outputs including a wireless charging pad, and adjustable charging speeds for weak circuits.
