The EcoFlow DELTA 2 is an outstanding energy station with a specification and worth that’s superior to a lot of the competitors. The LiFePO4 battery ought to imply it will final you a few years and not using a vital drop in battery capability. This makes it a perfect alternative for heavy customers similar to folks utilizing these extensively for off-the-grid residing, like canal boats or van-lifers.


  • LiFePO4 battery will final a few years
  • Quick cost speeds
  • Excessive photo voltaic enter capability


  • Decrease capability in your cash than the unique DELTA

I’ve beforehand reviewed the wonderful EcoFlow River Max 600Wh and, extra not too long ago, the Jackery Photo voltaic Generator 1000. I’ve now been reviewing the newest EcoFlow DELTA 2, which was launched at IFA simply a few weeks in the past.

That is the primary comparatively inexpensive energy station from EcoFlow that makes use of Lithium Iron Phosphate batteries, which considerably extends the lifetime of the battery in comparison with Lithium nickel manganese cobalt oxides (Li-NMC) which might be used on a lot of the different energy stations and plenty of competing manufacturers.

LiFePO4 vs Li-NMC Battery

Wanting on the numbers, it’s in all probability not value stressing a few energy station having Li-NMC vs LiFePO4, however I believe you will need to spotlight the significance of utilizing this type of battery. In the event you plan to make use of the ability station each day, then LiFePO4 can have some vital benefits long run.

On a traditional Li-NMC battery, it is going to take 800 full cost and discharge cycles earlier than the capability is lowered to 80%+ of the unique score. That is clearly going to final a very long time, it is 2.2 years of consecutive full expenses and discharges on daily basis. These usually are not like cellphones, I in all probability solely use my energy station a handful of occasions per yr. I might anticipate a number of years of use earlier than you discover any degradation in battery efficiency.

Nevertheless, these units are costly, and also you need them to final so long as doable.

With the LiFePO4 on this energy station, EcoFlow claims it is going to do 3000 cycles earlier than you begin to see the capability drop by as much as 20%. That is 8.2 years of full cycles each day.

In case you are off the grid residing and utilizing one thing like this each day, then it’s nicely value contemplating LiFePO4 over Li-NMC.


It is a huge Lithium Iron battery; there’s not a fantastic deal to debate with the design. However it’s a little completely different to Jackery.

With this, you’ve got a carry deal with on both facet, which makes selecting up the battery and strolling with it simpler in case you are not sturdy sufficient to elevate it with one hand.

Then the ports are on both facet of the unit, and the show is on the USB facet of it. The port placement is not fairly a consumer pleasant as Jackery, and I very often find yourself checking both facet to work out the place one thing is, however it’s hardly the tip of the world.

This then has a lot louder followers than the Jackery, which I assume is because of the 1200W mains charging.

Additionally it is value noting that the photo voltaic inputs for this usually are not the identical as Jackery, so I used to be unable to plug the SolarSaga 100W into this.

Battery Growth

One distinctive characteristic that units this other than the competitors is the power to increase the battery capability. This may be both through the £750 DELTA 2 Further Battery, which is mainly the identical spec because the DELTA 2 however with just one output port used to attach the 2 units collectively. Or, there’s the £1500 DELTA Max which extends the capability an additional 2016Wh.

I can not say how a lot use that’s, however having the choice is all the time good. On the very least, it means that you can prolong the capability to nearly the equal of the 3600Wh DELTA Professional for a complete price of £2600 vs £3500. You’d even have the pliability of 1 semi-portable battery you’ll be able to take travelling with you whereas having the prolonged storage a a lot bigger stay-at-home energy station has.

App and Settings

Having an app and an influence station with WiFi connectively appears a bit pointless, nevertheless it offers you extra settings that you could management simply.

The essential primary web page lets you already know the present size of time earlier than the battery runs out. What the enter and output are, and in addition, what the enter velocity is for both AC or photo voltaic.

Then throughout the settings, you’ll be able to set the AC cost velocity, automobile enter velocity, in addition to allow/disable the X-Enhance operate.

Photo voltaic Charging

My DELTA 2 arrived in September when the climate had began to change into a bit glummer, and I wasn’t in a position to take advantage of the solar as I did with the Jackery.

EcoFlow did not provide a photo voltaic panel, and I could not use the SolarSaga 100W, so I used the Mobisolar 100W foldable moveable photo voltaic panel. As a result of climate, I wasn’t in a position to get the identical constant photo voltaic charging as I did with the Jackery however I nonetheless managed to exceed 60W for shorter durations of time.

Utilizing the EcoFlow photo voltaic panels, you’ll be able to, in concept, cost this with as much as 500W photo voltaic. A single EcoFlow 400W photo voltaic panel will set you again round £1000. That is some huge cash, however my total home attracts about 800W after I work from home, so a 400W panel might simply maintain somebody going in the course of the day in an off-grid set-up.

Mains Charging

With this plugged into the mains, it could possibly cost as much as 1200W, which is considerably sooner than the Jackery energy stations I’ve reviewed.

My EcoFlow DELTA 2 arrived with 30% cost, and after I plugged it in, it knowledgeable me it could take simply 51 minutes to cost totally. The Jackery will take 7.5 hours, going from 0% to 100%.

The draw back to this extremely quick charging is that the ability station will spin up its cooling followers instantly, and they’re fairly loud. You aren’t going to get away with discretely charging this in a café at full velocity when making an attempt to reside off-grid.

It’s doable to set the cost velocity throughout the app, and I anticipate the followers will scale back at decrease speeds. I lowered the cost to 200W when utilizing it with my PC, and the followers considerably dropped in noise however nonetheless stayed on. The fan noise was louder than my PC, and better pitched.

In case you have a tool plugged in, it appears just like the EcoFlow will pull further energy from the wall to account for the units plugged in. With my PC plugged in and the cost set to 200W, I used to be seeing 340W. With no restrict set in place for charging, it drew 1420W. I assume it is because it was drawing 236W and powering the PC instantly whereas additionally drawing close to the utmost 1200W to cost the battery.

Additionally it is value noting that the included kettle lead for this energy station is specifically rated to deal with very excessive energy. You must subsequently maintain this cable secure and ensure you all the time use it with the EcoFlow.

Peak Output and X-Enhance

One other engaging characteristic of the EcoFlow energy stations is the X-Enhance operate which permits the ability station to attain a peak output of 2400W quite than 1800W.

Whereas the inverter itself can solely do 1800W, the X-Enhance regulates the voltage down for larger energy down, permitting you to run a 2400W machine at 1800W, whereas most different energy stations would run for a number of seconds earlier than the surge safety kicks in. This is able to clearly scale back the efficiency of the machine in query, for instance, a kettle will take longer to boil. Equally, some units will simply not work, however they’ve strict voltage necessities.

100W Energy Supply USB-C Charging

You get six USB ports in whole. Two are regular 12W USB-A then two 18W quick charging USB-A.

Then the 2 USB-C ports under these can do 100W. That is fairly an necessary characteristic for me because it permits me to cost most trendy laptops with out taking a devoted energy supply plug with me.

Testing and UPS Mode

I’ve examined this in quite a lot of circumstances, with it working completely in all situations, which is the minimal you anticipate for the sort of machine.

  • Similar to the Jackery, I ran this for twenty-four hours operating an under-the-counter fridge, with the same results of round 50% utilization throughout that point.
  • I used to be unable to seek out my USB energy tester however the energy station simply charged my Honor MagicBook 15 laptop computer instantly via the 100W PD ports.
  • I additionally took it away with me for a lad’s weekend and used it to energy two PerfectDraft machines and my Alpicool K25 automobile fridge. It was solely used for a number of hours on this situation earlier than the rain made us carry every part inside.
  • I then used it to energy my work PC each fully on the battery and within the UPS mode.
    • For UPS mode, the EcoFlow will mechanically detect that it’s plugged in and supply energy from the grid, not the battery. When energy will get disconnected, it is going to swap to the battery. Nevertheless, the swap time is <=30ms, not 0ms switching, and subsequently is probably not appropriate for some units.
    • To check the UPS switching, I unplugged the EcoFlow whereas my PC remained on, and issues continued to work as anticipated.

Worth and Various Choices

The EcoFlow DELTA 2 retails for €1,199 or £1,099.

For US patrons, there’s a 5% off low cost coupon which is legitimate from sixteenth Sep-2nd Nov:

  • 5% OFF Coupon code: EFDELTA2

The Anker 757 Transportable Energy Station is the biggest energy station Anker does, with a capability of 1229Wh utilizing LiFePo4. It’s fairly costly at £1,399, however you may get 10% on the Amazon web page.

BLUETTI do not do something within the 1KWh vary, however they use LiFePO4 on nearly all of their energy stations. The AC200P has 2000W and is priced at £1700, or the EB70 has 716Wh for round £700.

The PowerOak EB120 has a 1200Wh battery for £1,000 and appears to be a decrease spec model throughout the BLUETTI.

Then there’s the ALLPOWERS 2000W Transportable Energy Station, which really solely has 1500Wh and prices £1500.


The EcoFlow DELTA 2 is an outstanding energy station with a specification and worth that’s superior to a lot of the competitors.

The LiFePO4 battery ought to imply it will final you a few years and not using a vital drop in battery capability. This makes it a perfect alternative for heavy customers similar to folks utilizing these extensively for off-the-grid residing, like canal boats or van-lifers. This comes at a barely premium worth over the unique EcoFlow DELTA. That has 23% extra capability for simply £50 further or 4.5% further. Personally, I would favor the reassurance of LiFePO4 longevity, however, in actuality, contemplating my utilization, I’d in all probability by no means discover the distinction in efficiency.
