Product Description
The DELTA 3 Ultra Plus shares the standard Ultra's 3,072 Wh capacity and 3,600 W AC output, but doubles solar input to 1,600 W and adds a dedicated 378 W 12V/Anderson port alongside the usual cigarette lighter output. At 74.3 lb it's marginally heavier than the standard Ultra. Pick this one if you're charging mostly off solar or running 12V gear off it directly; if you'll mostly plug into a wall outlet, the standard Ultra covers the same ground.

Specifications from EcoFlow's published product data and user manuals.
What it will actually run
- A full-size fridge — roughly a day and a half to two days on a full charge
- A Starlink Standard kit — well over a day of continuous use at 75–100 W
- 12V accessories drawing up to 378 W through the Anderson port, alongside the usual AC loads
- Laptops, phones and cameras — dozens of charges from one top-up
What's different from the standard Ultra
Same 3,072 Wh battery, same 3,600 W AC output. The differences are in the DC side: solar input doubles from 800 W to 1,600 W, so panels recharge it faster off-grid, and it adds a 378 W 12V/Anderson output that the standard Ultra doesn't have, on top of the usual cigarette lighter port. It's also very slightly heavier and a touch shorter front-to-back.
Who buys this one
Anyone building a solar-first setup — a cabin, an overlanding rig, a boat — where recharge speed off panels matters as much as capacity. If your power almost always comes from a wall outlet, the extra solar input and 12V port won't do much for you, and the standard Ultra makes more sense.
Where people use it
Common questions about this product
Comfortably for most of a day or two. A full-size fridge uses roughly 1–2 kWh over 24 hours; with 3,072 Wh on board, this station covers anywhere from a day and a half to three days depending on how efficient the fridge is.
No. At 3,072 Wh it's more than thirty times the 100 Wh airline limit for carry-on or checked batteries. It ships by ground or freight, not in luggage, so factor that into travel plans if you're flying somewhere and need power on arrival.
This model accepts up to 1,600 W of solar input, double the standard Ultra, through EcoFlow's own connectors. Whether a third-party panel matches depends on its plug type and voltage — call us at (619) 238-0205 and we'll confirm compatibility before you buy anything.
It uses LFP (LiFePO₄) cells, which EcoFlow backs with a 5-year warranty — 3 years standard plus 2 years extended once you register the unit in the app. We don't have an exact cycle-count figure to quote, but that warranty length reflects real confidence in the chemistry.
Yes. A Starlink Standard kit draws roughly 75–100 W, so a full charge here runs it for well over a day of continuous use. A Starlink Mini, at 25–40 W, stretches out to several days on a single charge instead.
Not to use it as a portable station — plug loads directly into its AC outlets or the 12V/Anderson port, no wiring required. If you want to wire it into a breaker panel through a transfer switch for whole-home backup, that installation does need a licensed electrician.
Can I buy a satellite phone?
Yes you can buy satellite phones, we offer the best satellite communication options. Including Iridium, Globalstar, and Inmarsat. Satmodo offers satellite phones that work anywhere in the world.
Do I need to rent or purchase a satellite phone?
