3,600 W running, 7,200 W surge — sustains the fridge, freezer and the essentials tier and everything below it.
Best forHouseholds that want a few days of essentials backup in one lighter unit and do not need 240V or later expansion.
Jackery's current non-expandable 3kWh unit and, at 59.5 pounds, one of the lighter ways to get a 3,600W inverter. 3,072Wh of LiFePO4 with 3,600W continuous and 7,200W surge covers a fridge, furnace blower, sump pump and a few circuits for a day or more, and a dedicated 120V 30A outlet takes an RV cord or a manual transfer switch's inlet. It is single voltage: no 240V, so a home panel's well pump or dryer is out of reach. The wall recharge takes about 2.2 hours. Against the Explorer 3000 Pro it replaced, the weight and the quieter fan are the gains; the gripe is the same as with the 2000 v2: no expansion, because Jackery's FAQ says to buy a 2000 Plus or 5000 Plus if you want to stack batteries. Jackery publishes no noise figure for it, and lists it at $1,499 while discounting it most weeks.
