Jackery Explorer 240 v2 is a compact power station with lithium iron phosphate cells, built for one appliance at a time: a computer, a modem, a lamp. There's only one AC outlet, and it isn't made for appliances that draw a lot. The USB-C port does double duty, since it's both the main input for charging it and the most generous output for powering a laptop.

It charges from the home outlet, the car's cigarette lighter socket - only on 12 V systems, not 24 V - or the sun, and for the sun an adapter sold separately is needed, because the panel plugs into the same USB-C port. If it stays on with nothing connected and no charging in progress, it turns itself off after a couple of hours, so it doesn't drain itself idle: the time can be changed from the app.

It's light and built to be moved often: camping, traveling, or as backup for a short outage at home. It's turned on and adjusted from its own buttons, and the app is for checking on it from a distance, not for making it work. It isn't the right choice for anyone who needs to keep several plug-in appliances running together.

The rest of the data comes from one page on the manufacturer's site, cited row by row in the table above.

A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.

03 · Summary

Pros and cons

In favour

The hundred-watt USB-C port charges a laptop without carrying its own charger along.
When power fails, the running computer and the modem don't notice.
At startup it briefly accepts double the power it holds continuously: enough to start a small motor.
It fits in a backpack and gets carried around all day without being felt on your back. source

Worth knowing

It shouldn't be connected to a server or a workstation that can't tolerate even a moment's interruption. source
It has only one AC outlet: the second plug-in appliance waits its turn.
Charging it from the sun needs an adapter sold separately, because the panel plugs into the same USB-C port as the grid. source
