Huge power capacity for all kinds of activities

No gas, no noise, and no maintenance, the EcoFlow DELTA is a highly popular device praised for its awesome features. It has a huge 1260Wh capacity, so you can keep your home devices fully charged during power outages and emergencies. You can also ensure your lots of gear stays powered up while enjoying outdoor recreational activities. Not only that, the DELTA could help you take your professional and DIY work to the next level when away from the grid.

A great addition to a portable generator

If you already own a gas/LPG portable generator the EcoFlow DELTA may be just the addition you need to add to any other items of your independent power delivery equipment. That’s because you could substantially reduce costs and increase convenience by instead using the DELTA to connect lower energy appliances in place of powering up your portable generator. It can last up to several days before needing to recharge and, with the fastest recharge times in the business, you could find yourself using it over and over again.

Power up to 13 devices with the Delta’s multiple ports and outlets

Equipped with 6 AC outlets with a total of 1800W continuous power from a 1260Wh capacity, you can comfortably power up to 13 devices at the same time. And a surge capacity of 3300W allows you to start more demanding devices. All this power means that the Delta weighs in at just 30.9lbs, making it a perfect companion for every serious adventurer and camper who demands reliable and durable power on the go.

Ultra-Fast Recharge

EcoFlow’s Class leading recharge time is the best in class, taking only 1 hour to charge from 0 to 80%, and 1.6 hours to full charge utilising EcoFlow’s patented X-Stream Technology, which is up to 10X faster than the competition.

X-Stream Recharge Technology

Solar Charging

You can charge the unit from the AC wall outlet and with the included 12V adapter, as well as using solar panels for virtually limitless power. Full charge is possible in 3.5-7 hours with connections to three EcoFlow 160W solar panels, and in just 4-8 hours to four EcoFlow 110W solar panels (paid links). 

Power Outlets

With 13 output ports, including 6 x AC outlets, and multiple USB ports, the DELTA can power up just about any of your devices at the same time (within a total combined 1800W).

Features of the EcoFlow DELTA Power Station

Frequently Asked Questions

What can this device power?

X-Boost technology allows powering some, but not all, devices up to 1800W. It’s not suitable for powering items such as A/Cs, larger fridge-freezers and microwaves (a 600W microwave would be okay), which have a high peak power need.

Can I use this as a UPS?

As an Emergency Power Source (EPS) it’s not advisable to use it as a UPS. For example, connected devices will no longer receive power if the unit becomes fully discharged for any reason.

How long will the battery remain charged in storage?

The battery shelf life (storage) is 1-year, meaning the power station can be stored after it has been fully charged and it will last for a year without losing its capacity. However, it is advisable to charge the power station at regular intervals before the year is up to help lengthen the battery life.

Can I take this power station on a plane?

No, the Li-on battery size exceeds by far that permitted by the TSA for safety reasons, so you should never attempt to take it by air.

Can I use the unit while it’s charging?

Yes, it outputs power even when the unit is being charged. Bear in mind that charging the DELTA will take considerably longer.

Does this unit have Wi-Fi?

No, currently this is the only EcoFlow model that is not equipped with Wi-Fi technology.

Is the unit really silent?

For all practical purposes, yes. The unit has an internal fan that operates when needed to provide cooling, and is only really audible when standing very close by. The fan runs when it is being charged.
