1024Wh (51.2V⎓20Ah). Capacity is the figure that decides how long it runs a given load, so it is the first number to check against what you intend to power.
Its AC output is rated Pure sine wave, total 1800W, surge 3600W US/CA: 120V ~ CN/KR: 220V ~ EU/UK/AU/CH/ZA: 230V ~ JP: 100V~ (total 1500W, surge 3000W) That rating, not the capacity, is what decides whether an appliance will start at all.
Approx. 12.1 kg (26.6 lbs). Worth knowing before you plan to carry it — weight is the specification most often discovered after delivery.
