Make it a triple.

Double or triple the capacity of your DELTA Pro to 7.2kWh or 10.8kWh. That’ll give you days of power for your essential appliances.

Charge anytime, anywhere.

DELTA Pro’s Smart Extra Battery benefits from all the charging methods DELTA Pro has, including 6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro. Once connected, they’ll charge/discharge in unison, keeping the battery percent level across both units.

Ready for any emergency.

When the going gets tough and you’re out of charge options, get a 1800W DC fast charge with EcoFlow Smart Generator (sold separately). Just plug the generator directly into your extra battery via the port on the back. This works even when disconnected from your DELTA Pro.

Stay informed.

The Smart Extra Battery sports a bright LCD screen on the front of the unit giving you all the info you need. Output, input, remaining charge and time remaining. It’s all there. Need on the go info? The EcoFlow app can tell you all that & a whole lot more.

Terrific battery with a very short cord

Battery works as advertised. Ive got 3. The only complaint is the cable that conects to the Delta Pro is absurdly short and the add on batteries must be located alongside the Generator. You can't put the battery below the generator. I was hoping to put my generators on an upper shelf and the generators below. Cannot be done with the short cables.

Most advanced generator in its class

I own this Delta Pro as well as three other Ecoflow products. I also own other brands including Jackery. In my opinion the Delta Pro wins out in multiple fronts - including the battery chemistry used, cost per watt hour, and the supporting app and features which can be customized within. Among these the charge rate was my favorite aspect to control. I picked this up for power outages in my area and so far its served that purpose well. Its more power than I actually need but its nice to not worry about whether it will work when powering any of my appliances. Build quality is very good and from the various tear down videos Ive seen the consensus seems to support that this is a well built and well engineered product. I also picked up the cover for it which is visible in the picture. It also fits the Pro well and allows operation without removing it and stores the ac adapter. Ill also mention that Ecoflow seems in general to keep pushing the market forward with their products which is a great thing. Solid product and good purchase.
