EcoFlow Delta Battery Is The Antidote To Emergency Generators

The new DELTA backup battery system from EcoFlow features up to 1800 watts of power, silent operation, and rapid recharging capability. Order it now on Kickstarter for delivery in December.

What do you do when the lights go out at your house? Most of us scurry around looking for candles or lanterns and wait for the electricity to come back on. A few have backup generators in the garage, but since the power usually fails at night, getting it started and plugged in correctly is a hassle. And don’t let it run near an open window or door if you don’t want to get asphyxiated. Small gasoline engines are terrific at producing carbon monoxide as they run.

EcoFlow was founded in 2016 with the specific purpose of making gas-powered backup generators obsolete. This week, the company announced its new DELTA battery, which it says is the most powerful backup battery on the market.

In an e-mail to CleanTechnica, co-founder Eli Morgan Harris says, “From home energy storage to electric vehicles to mobile power, the world is moving to batteries. We founded this company to dethrone the gas generator and that is exactly what DELTA does. We’re proud to bring to market the first higher-performing, affordable, and sustainable battery alternative to a gas generator. DELTA can even recharge your Tesla.”

The new DELTA backup battery weighs about 30 pounds — far lighter than any standard gas powered generator you are likely to find. It has a capacity of 1300 Wh and continuous AC output of 1800 watts, which is equivalent to about 16 amps, according to The Verge. It also has a 3300 watt surge capacity to accommodate spikes in power as connected appliances are powered on. It even has enough power to move your Tesla another 5 miles down the road in an emergency.

The DELTA features four regular USB ports, two 60-watt USB-C ports, and six 110 volt wall outlets for US customers. For European customers, it comes with four 220 volt wall outlets. Recharging to 80% SOC takes just one hour from an ordinary wall outlet or two hours to 100% SOC, thanks to the company’s proprietary X-Stream charging technology. If you have solar panels available, the unit can be recharged in about 4 hours, assuming the panels are capable of producing 400 watts and the sun is shining brightly.

Utilizing the company’s patented Battery Management System, the DELTA provides a full suite of protective measures for both software and hardware so the backup battery can always operate at the highest charge and discharge rate while prioritizing safety for the devices it is powering.

Rugged, lightweight, zero maintenance, and with no carbon emissions, the EcoFlow DELTA is priced lower than many gas-powered backup generators. The 1800 watt unit is available now on Kickstarter for $799. A 1000 watt version costs $699. The company expects to begin shipping the DELTA in December.

(Note: many of the components for the EcoFlow DELTA are sourced from China, and you know what that means.)

There’s one more feature of the EcoFlow DELTA that is sure to make you smile. It is silent when in operation, which means the gang of merry pranksters at CleanTechnica can use it to run the lights and sound system for our next poolside disco party without having to listen to the drone of an internal combustion engine all night. Just that feature alone makes the DELTA worth the asking price. Cue the BeeGees!

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
