What this station is
The Jackery Explorer 300 Plus stores 288 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 3.8 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 300 Plus covers about 9.7 h of that.
A fridge needs about 700 W for a second when its motor starts. The Jackery Explorer 300 Plus gives 300 W, so it will likely not start one.
Charging it
The brand does not list a solar input for it. Charge it from a wall outlet before you need it, and top it up every few months.
Questions about this station
How many days of power cut does the Jackery Explorer 300 Plus cover?
About 9.7 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 300 Plus 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 300 Plus 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 1.4 nights. The heated humidifier uses much more: turn it off, or use the 12 V cable sold by the CPAP maker.
