How long will the C300X run my devices?

At its 300 W limit it lasts just under an hour. A 50 W laptop or fan gets roughly five hours, and phones charge many times over.

Can it run a fridge or a heater?

No. Its 300 W continuous output and 288 Wh capacity are too small for fridges, heaters, kettles or power tools. It is meant for electronics and lights.

How fast does it recharge?

About 4 hours from a 120 V wall outlet and about 6 hours from the included 60 W solar panel. The 140 W USB-C port can also recharge it.

What comes in the box?

The C300X station, a 60 W solar panel, and the charging cables. Check the listing for the exact cable set.

Is it safe to leave in a hot car or use in winter?

It is rated from -4°F to 104°F. Avoid charging below freezing, and keep it out of direct sun in summer.

How does it compare with the Jackery Explorer 300?

Both are around 300 Wh. The C300X adds LiFePO4 cells with a longer cycle life, faster USB-C and a bundled solar panel, but its output ceiling is similar.
