EcoFlow Delta Pro 3 review: Portable Powerhouse

I never really considered how useful it would be to have a portable power station that had enough guts to power any appliance around the home.

There’s a peace of mind element, for certain, that lets you use the station as a backup in a power outage. But for me, testing the Delta Pro 3 has given me much more flexibility around the home.

For a start, it’s got enough output to power an electric grill like the Ninja Woodfire Grill. The DJI Power 500 couldn’t do that, though it was targeting a different market.

The level of capacity, and power output, that the Delta Pro 3 offers makes it extremely versatile. It can power your fridge for days during a blackout, or it can be used as an outdoors power source where you don’t have a power point.

If you have a camper van or caravan, it can be used to power the appliances, and then recharged with solar panels and your car battery.

It’s big, heavy, and expensive. But the Delta Pro 3 is an impressive unit for anybody needing portable power.

What is the Delta Pro 3 offering?

In a word? Power.

The Delta Pro 3 is a beast of a unit. It weighs 51.5 kg, and measures in at 693 × 341 × 410 mm. In that body, you get 4 kWh of battery capacity, and the ability to output 4,000 Watts from the LFP batteries.

Fortunately, its bulk is made slightly easier to manage by the two wheels on the base and the retractable handle that lets you move it around like a suitcase. It’s still heavy, but it is portable.

That high output is key for the Delta Pro 3’s ability to act as a home backup power solution. You can plug it in to high power-draw appliances like your fridge, and it will happily keep it running for a few days.

If you’re really serious about using the station as a home power backup, you can expand that capacity to 12 kWh with additional battery units, though that price is going to jump up significantly if you go down that route.

The Delta Pro 3 is packed with power ports. You get four standard AC ports for plugging in standard appliances, plus two USB-A ports and two USB-C fast charging ports.

It has a clear and bright colour display so you can easily see how much charge is left and what the power output looks like. The EcoFlow app lets you track that information and manage the power station remotely as well.

While the Delta Pro 3 can power just about anything, it also offers a huge number of ways to power up, which is key for versatility.

You can charge by a standard wall plus, obviously. But it also accepts charging via solar panels, electric vehicle chargers, traditional car cigarette lighters and can even be charged by a gas generator. What’s more, you can combine different methods to charge the unit faster.

You can also use the Delta Pro 3 as a UPS with a response time of <10ms, but I feel that is massive overkill for the range of options and power this product offers.

What does the Delta Pro 3 do well?

This thing is as good as it gets when it comes to powering appliances. I typically used it to avoid needing a long outdoor extension cable when cooking using the Ninja Woodfire Grill or the Ninja Woodfire Oven, but it also was useful charging the Ecovacs Winbot W2 Pro Omni during testing.

Powering devices is quick and quiet. EcoFlow says it’s under 30dB when power use is under 2000 W, and I can say I honestly didn’t hear it at all.

The whole system is plug and play. You don’t need a degree to use it, which is nice. Simply plug in the appliance or device you want charged and turn on the Delta Pro 3 and it will charge.

The other great benefit of this unit is that it doesn’t take forever to charge up. You can plug it into a range of charging sources to charge even faster, but EcoFlow says that you can get it from flat to 80% in just 50 minutes using the company’s fast charging technology.

The batteries themselves are Lithium Iron Phosphate, which are the safe kind of lithium battery. EcoFlow says that the battery will still charge to 80% after 4000 cycles, which is enough for about 11 years of usage. Obviously, I couldn’t test that, but it sounds like this has the longevity you want from a portable power station.

I also want to call out the IP65 rating. If you were to take this power station camping, it’s good to know that it can handle a bit of both dust and water. Obviously, you would rather not submerge it at all, but a light sprinkle isn’t going to make your expensive power station an expensive brick.

What could the Delta Pro 3 improve?

Honestly, the greatest challenge here is the sheer weight of the unit. At 51.5 kg, it’s too heavy to easily move, even with the wheels and retractable handle.

For tent camping, you definitely want a more lightweight solution, though if you have a camper trailer or caravan, this would be a great option.

The other catch is the RRP. The Delta Pro 3 launched with an RRP of $6,699, but had a launch offer of $4,099.

That’s a bloody ridiculous price difference. If EcoFlow can afford to sell the unit at just over $4K, it should stick with that price. As I write this, it’s sitting at $4,999 on the EcoFlow web store.

Verdict

The Delta Pro 3 is designed to be a versatile power solution, whether you’re a camper looking for a portable power solution or someone searching for a home battery backup solution.

Well-designed, simple to use and intelligently expandable, this ticks almost all the boxes. Its only real downfall is its bulk – at over 50 kg, it’s probably too heavy for many grey nomads to transport around easily, and becomes quite cumbersome for portability with car campers.

That said, it is reliable and powerful, and a clear choice as one of the best portable power stations in Australia.
