EcoFlow Delta Pro battery review: maximum solar power for an uncertain world – The Verge

September 10, 2022 by No Comments

It’s hard to imagine, but there could soon come a time when a 100-pound battery on wheels that costs $3,699 is something you’ll want or even need.

Maybe it’s because you want to take out some insurance in the form of emergency backup power now that the public grid is increasingly under siege by heatwaves, fires, and floods. Or maybe, like me, you just want to take advantage of your employer’s new work-from-home policy to disappear into the forest for weeks at a time with a laptop, Starlink RV, Super73-ZX e-bike, and all the latest gadgets that define modernity.

Either way, you’ll need a very powerful battery, and one that’s flexible enough to be refueled by whatever means is available. In other words, something like the Delta Pro from EcoFlow.

The Delta Pro is a suitcase-sized battery designed to handle the unexpected. It’s relatively portable, loaded with DC and high-wattage AC outputs, and can be charged in half-a-dozen ways including solar panels and from thousands of level 2 EV charging stations.

Not only did a 3.6kWh Delta Pro and 400W EcoFlow solar panel keep all my family of five’s gear charged for three weeks without dropping below 55 percent, but this big-ass solar generator also proved capable of charging an RV and an entire house without even flinching.

Good Stuff

  • Many ways to charge it
  • LFP battery charges fast and should last a very long time
  • Monitoring and controlling live input and output activity from the app is informative and addictive
  • Wheels and telescoping handle make it reasonably portable

Bad Stuff

  • Big and heavy
  • Not cheap
  • Not as reliable as a diesel generator for emergency backup
  • App doesn’t maintain history

I’ve been covering EcoFlow since the company launched its first product in 2017. In that time, it has gone from making standalone batteries to creating an entire ecosystem of products that build upon one another as your needs evolve. Sonos customers will immediately recognize the approach: you start with a single speaker, then a second for real stereo separation, then a Sonos soundbar to create a home theater, and later a subwoofer to round out the 5.1 sound. At this point, you’re so locked in you’re unlikely to buy anything else.

With EcoFlow, you buy one of its flagship 3600Wh Delta Pro batteries, then an EcoFlow expansion battery or two to boost capacity to 10.8kWh, and then some EcoFlow solar panels to keep it all charged in an environmentally friendly way. You find you’re not using your $10,000 setup all the time so you fit an EcoFlow smart home panel into your electricity box so that the entire house can still be powered during a temporary blackout, and then add an EcoFlow dual-fuel generator for serious emergencies to keep everything powered for as long as you feed it diesel or propane. Or maybe take all that gear off-grid to augment the performance of EcoFlow’s turnkey Power Kits installed in a remote cabin or RV. Then kick back with a portable EcoFlow AC unit in comfort and watch the fossil fuel-obsessed world burn.

I reviewed a European model of the Delta Pro, which differs only slightly …….
