Pros and cons

Pros

The stated 3600Wh capacity and 3600W total AC output support a substantial battery-backup setup compared with smaller-capacity portable units.
A broad set of outputs, including USB-C up to 100W per port and five AC outlets, can serve several kinds of devices.
Expansion is described up to 25kWh, which may suit buyers planning a larger backup system rather than a fixed-capacity unit.
Several charging routes are listed, including AC, solar, car, and EV station charging.

Cons

At 99 pounds, the listed weight makes frequent carrying or solo transport a significant practical trade-off.

What to know before buying

The stated 1.8-hour recharge figure depends on a 240V, 3000W outlet, the 2.7-hour wall-outlet claim specifies 1800W, and the solar figure assumes four 400W panels.
The listing describes expansion equipment and solar charging, but does not include expansion batteries, a smart generator, or solar panels in the explicit package list.

Listing details to confirm

Listing details are inconsistent: the title states 3600W AC output, a details field lists 4500 for output wattage, and the specifications distinguish 3600W total AC output from 4500W maximum device power with X-Boost, confirm the applicable output limits for your devices. Recharge times also vary by input: the stated figures are 1.8 hours at 240V, 2.7 hours at 1800W wall input, and 2.8 hours with four 400W solar panels.
