What a compact unit can and cannot do
Two units, similar size. EcoFlow's RIVER 3 Plus stores 286 Wh with a 600 W rated output and was $299.001. Jackery's Explorer 300 stores 293 Wh with a 300 W inverter (500 W surge) and was $289.002.
Output decides what plugs in. At 300 W the Explorer 300 cannot run a 500 W appliance at all; the RIVER 3 Plus can, briefly. Neither is sized for a refrigerator through an outage.
Small loads drain faster than the math. EcoFlow says the RIVER 3 Plus can power a 3 W router for up to 35 hours1. That is 105 Wh of its 286 Wh, about 37 percent, because the unit itself uses power while running. Plan on the maker's own runtime examples, not capacity divided by watts.
Switchover. The RIVER 3 Plus states a switchover under 10 ms, so it can sit between the wall and a router or computer as a backup supply1.

Our arithmetic: stated capacity (Wh) x 0.75 / appliance watts. The 0.75 usable share is the highest implied by the makers' own runtime examples we read (Jackery Explorer 300: 55 W blanket for 4 hours from 293 Wh); small loads get much less. A real appliance cycles on and off, so measure it if you can.

Compact unit questions
Will a compact unit run a CPAP overnight?
It depends on the machine's draw and whether the humidifier is on. Check the CPAP's power label or manual, then use our runtime guide. This is not medical advice; ask your equipment supplier about backup power.
Can it run a refrigerator?
Not through an outage: under 300 Wh is sized for electronics. Look at about 1 kWh and up.

We do not earn anything from purchases today. Every product link is a plain link to the merchant's own page, without an affiliate code. We may join merchants' affiliate programs in the future, and this notice will say so before that changes.
Prices and specifications are each maker's own, as listed on the date shown, and change often during sales. The maker's page is the final word on price, availability and terms.
Runtime figures are estimates from stated capacity, not measurements. OutageReady Guide does not sell power stations and has not tested any product.
