Questions

How long will the Jackery Explorer 240 v2 run a refrigerator?

It may not: a typical fridge compressor needs about 1,200 W for a moment to start, above this model's 600 W surge rating. Newer, smaller fridges may start fine.

Can the Jackery Explorer 240 v2 run a microwave?

Not a full-size one. A typical 1,000 W microwave pulls about 1,500 W from the outlet, more than its 300 W continuous output.

How long does the Jackery Explorer 240 v2 take to charge?

Jackery's published charging claim: “0–100% in ~1.9 hr (AC); ~1 hr with Emergency Charging in the app”. With solar, it accepts up to 100 W. With 100 W of panels that's roughly 3.4 hours of good sun from empty.

Is the Jackery Explorer 240 v2 expandable?

No. Its capacity is fixed at 256 Wh.

Does the Jackery Explorer 240 v2 work as a UPS?

Jackery lists a 20 ms switchover time, so it can keep devices like routers and computers running when the power drops. Check that your specific device tolerates the switch before relying on it for anything critical.
