EcoFlow DELTA 3 Portable Power Station
Product Description
The DELTA 3 is the size most people actually need: 1,024 Wh and 1,800 W in a 27-pound case you can carry in one hand. It covers a long weekend of camp power, keeps a satellite terminal and a fridge going through an outage, and is quiet enough to run inside a tent — the thing no generator can claim.

What it will actually run
- Starlink Mini: roughly a day of continuous use, longer if you switch it on only to check in
- 12 V camp fridge: about a day
- Laptop: ten to fifteen full charges
- Satellite phone or messenger: dozens of charges — these are a rounding error in the budget
- CPAP without humidifier: two to three nights
- String lights and phone charging for a camp of four: several days
Who buys this one
Car campers, overlanders and van owners who want one box that covers everything electronic, and households that want a fridge, a router and a couple of lamps carried through a normal outage. It is also the size that makes sense as a first power station: big enough to be genuinely useful, small enough that you will actually bring it.
Pairing it with solar
A 220 W folding panel puts roughly a kilowatt-hour back on a clear day, which is more than most people use — that combination runs indefinitely. A 110 W panel covers a lighter load. Anything inside 11–60 V and 500 W works, including most third-party panels with MC4 connectors.
Where people use it



Common questions
They share the same 1,024 Wh battery, 1,800 W inverter and chassis. The Plus adds faster USB-C charging and a wider set of expansion options. For most buyers the deciding factor is price and which one is in stock — the power you get is the same.
For two people with phones, a satellite messenger or phone, lights, a camera and a laptop, comfortably — that load is well under 200 Wh a day. Add a 12 V fridge and you are at roughly one day per charge, which is why a folding panel is the usual companion.
Small ones, briefly. 1,800 W covers a 1,500 W heater, but it will empty a 1,024 Wh battery in well under an hour. Resistive heat is simply a poor match for battery storage — a station this size is for electronics, tools, a fridge and lights.
Under 30 dB at 600 W, which is quieter than a normal conversation and inaudible from a few feet away in a tent. That is the practical argument against a generator in a campground.
Yes — at up to 800 W with an alternator charger, which fills it in about an hour and twenty minutes of driving. Through a standard 12 V cigarette socket it is much slower, around 100 W.
Yes. Leave it plugged into the wall with the device plugged into it, and the switchover on power loss is under 10 ms — fast enough that a desktop, a router or a Starlink terminal will not reboot.
