EF ECOFLOW Delta 3 Classic Portable Power Station Keeps Your Electronics Powered During Emergencies for $399

Power outages can come at the worst times, catching you flat-footed and scrambling for extension cords and gas cans. Luckily, the EF ECOFLOW Delta 3 Classic portable power station comes to the rescue – and at a much more affordable price now that it’s down from $599 to $399. This nifty little device is always there when you need it, whether you’re bracing for a blackout or just headed out on a weekend adventure, and it won’t take up much space in the trunk either.

Capacity is the key to a good power station, and the Ecoflow Delta 3 has 1024 watt-hours of lithium iron phosphate battery. That means you can keep a mini-fridge running for 15 hours straight or charge your laptop a dozen times without a hitch. And this LiFePO4 battery chemistry is a big step up from older types – it’ll last for 4000 charge cycles before you start to see a drop in capacity, holding steady at 80% or better.

The Delta 3 Classic has got you covered for all your modern gear needs with 6 regular AC outlets that can deliver 1800 watts continuous and a surge of 3600 watts if you need a quick jolt – that’s enough to power up a microwave or your power tools without even breaking a sweat. You’ve also got 2 USB-A ports for getting your smaller gadgets charged in a hurry and a 100 watt USB-C port that can handle bigger devices like tablets or small monitors. And of course there’s the DC outputs – a vehicle port and two cigarette lighter plugs for 12-volt needs, so it connects to all sorts of gear you might have lying around.


What really sets the Ecoflow Delta 3 Classic apart in a crowded market is its charging speed. Plug it into the wall and it’ll hit 80% capacity in 45 minutes with a 1500 watt input, and full capacity isn’t long after that. Plus, it’s a breeze to use with solar panels – just set it up and the midday sun will have it fully recharged in under 2 hours, even on partly cloudy days. And if you’re on the go, car charging is easy as well, drawing power from a 12-volt outlet at a steady rate.


Now, the key to a portable power station is balance – make it too heavy and you can’t lug it around, make it too light and it might not be durable enough. The Delta 3 Classic gets that balance just right, weighing in at a manageable 27 pounds and measuring 15 x 8 x 11 inches. The tough plastic shell can handle being tossed into the back of the truck or hauled across the site, and the built-in handles make it easy to carry – it’s light enough for most adults to handle on their own, and robust enough to withstand everyday bumps. Campers take it along without complaint, and homeowners stash it away in the closet between uses.


App integration gives you a whole lot more control – takes it to the next level in fact. Connect to the Ecoflow app on your phone via Bluetooth or WI-Fi and you can check battery levels in an instant , change your output settings, even schedule charges right from your phone. One of the perks is that firmware updates just get beamed straight to your unit, so any little niggling issues can be sorted out before they become a real problem.


Future proofing your investment is what the expansion options are all about. If you want to take things to the next level, you can add on more batteries from the Ecoflow family – the DELTA 2 or their Pro series for instance – and bump up your capacity to a full 5 kilowatt-hours, or cover the whole house during those longer outages. The 10-millisecond switchover means your delicate electronics will be safe from those nasty power surges, and if you do happen to overload the thing it will just automatically switch off to prevent any damage. And the unit’s whisper quiet fan (just 30 dB) is quiet as a mouse even when it’s working flat out.
