What this station is
The Jackery Explorer 240 v2 stores 256 Wh of energy, as announced by the brand. Its outlets can give up to 300 W at the same time: add up the watts of everything you plug in and stay under that number. It is a small station: good for phones, a laptop, a router and lights, not for a fridge over a long time.
Its battery is LFP (lithium iron phosphate). This type usually keeps most of its capacity after thousands of charges, so it suits a station you use often. At 3.6 kg, you can carry it with one hand.
During a power cut
A simple day without power: the internet router on for 24 hours, two LED lamps for 6 hours, a phone charging for 3 hours, and the station itself switched on. That comes to 606 Wh per day. The Jackery Explorer 240 v2 covers about 8.6 h of that.
A fridge needs about 700 W for a second when its motor starts. The Jackery Explorer 240 v2 gives 300 W, so it will likely not start one.
The brand announces a switch-over time of 20 ms: if mains power drops, devices plugged into it keep running. Useful for a router or a computer.
Charging it
It accepts up to 100 W of solar panels. Even in full sun, a full charge takes at least 2.6 h. In practice panels give less than their rated watts, so count on longer, often a few days in winter.
Questions about this station
How many days of power cut does the Jackery Explorer 240 v2 cover?
About 8.6 h for the basics: router, two LED lamps, a phone and the station itself, 606 Wh per day. Each extra device shortens that time. Try your own list in the calculator.
How long can the Jackery Explorer 240 v2 run a fridge?
Probably not: a fridge needs about 700 W for a second when its motor starts, and this station gives 300 W.
Can the Jackery Explorer 240 v2 run a CPAP machine all night?
Yes. A CPAP without heated humidifier uses about 12 W. Over 8 hours, with the station itself switched on, that is 176 Wh per night, so about 1.2 nights. The heated humidifier uses much more: turn it off, or use the 12 V cable sold by the CPAP maker.
