What Makes the Delta 2 Different?
That means the battery is going to last for longer.
If you’re going to use it frequently, that should be a key consideration.
That’s rare for a smartphone app, let alone in the world of backup batteries.
You’ll find a carry handle situated on both the front and back.
These will vary by country, but the UK model has four, situated fairly close together.
Further under those, youll also find a 12V car port, plus two DC5521 ports.
Only the car port is covered with a rubber protector bung.
The AC, DC, and USB port sections all feature their own power switches.
So, what can you power with the Delta 2?
This one breakfast used less than 10% of the power reserve.
The capacity is 1000 Watt-hours, which means it can power a 1000 Watt rig for 1 hour.

However, you could’t daisy-chain additional units, so 2 or 3kWh is the hard limit.
What is Xboost Mode, and How Does It Work?
I mistakenly tried my electric kettle, which is actually rated to 3000W.
With Xboost mode enabled, the kettle overloaded the battery after about thirty seconds.
But initially, I wasn’t sure why.
Both the app and LCD panel reported it was drawing only a little under 2100W.
I reached out to Ecoflow support.
Was it under-reporting the actual power draw?
Xboost mode worksvery cleverly, I thinkby reducing the output voltage, while increasing the available current.
Most high-power appliances such as hair dryers don’t mind this at all.
It just means they’ll run a little slower than normal, or get a bit less hot.
However, the total output power still can’t exceed 1800W.
In my case, the kettle was undervolted in Xboost mode by about a third.
Hence my 3000W-rated kettle was boiling more slowly than usual, and only drawing just over 2000W instead.
Without Xboost mode enabled, the kettle overloaded the battery immediately.
Of course, because at its normal voltage, it was trying to pull the full 3000W.
On the other hand, if you oughta charge quickly, AC charging is the way to go.
Thankfully though there are no external power bricks neededall the electronics are contained within the Delta 2 itself.
At the full 1200W AC charge rate, it’ll take 1 hour 20 minutes to fully charge.
That’s a full charge every day for 8 years.
Ecoflow is pretty much leading the way in this regard.
Even competitors in the large battery space usually only promise 500 to 1000 cycles.
It’s also one of the most reliable battery apps I’ve used yet.
Since I’ve already got the app installed and logged into my account, setup was a breeze.
The app automatically detected a new EcoFlow battery over Bluetooth and prompted me to add it.
From there, you should connect it to Wi-Fi as well for remote access.
So while the app view is simplistic, it is reliable, and quick to refresh.
The only thing missing for me is IFTTT or other automation support.
Is This The Best Mid-Capacity Portable Battery Yet?
The Delta 2 is very much a portable high-capacity battery, rather than a hybrid modular whole house system.
However, I do think EcoFlow could have leaned into the portability features more.
For instance, a camping light would be great.
A rugged, dimmable LED on one of the side panels would mean one less gadget to carry.
The Delta 2 also lacks wireless charging, which means you had better remember your cables.
As the famous saying goes… “make haycharge batteries while the sun shines”.
