Key Features
Introduction
break away from the superpower control grid does n’t stand for that we necessarily want to give up our electric goods . That ’s where the EcoFlow Delta 2 come in .
I ’ve reviewed portable major power station before , but this barrage fire - power gimmick is one of the most potent yet : with its 1,024Wh barrage fire and high output , the Delta 2 can make out with pretty much every menage widget , which pee it utilitarian on camping trips , as well as for fill in around the dwelling if there ’s a blackout .
Design and Features
I ’ve reviewed theEcoFlow River Probefore , but the Delta 2 is a step up from that model in price of features and its capacity . Coming in at 12 kg , the Delta 2 is at the limitation of what you could consider portable . I find that the large handles let me lug it from theatre to car , or from way to room .
The main standout feature is that the Delta 2 supports machine up to 1,800W , with X - Boost technology preventing overload from machine up to2,400W. EcoFlow does say that ten - Boost engineering is good for twist that have less stern potential requirements , and it ’s particularly suitable for heaters .
As a upshot , this power station can handle more than 90 % of household gadget – that ’s everything from TVs and laptops to grills and even lower - power kettles . This makes the Delta 2 worthwhile around abode with unreliable office supplies . In fact , I used it for watching TV , blackguard umber and mixing kale with no performance issue .
It helps that this example has four UK power sockets , situate at one end , which gives a fair amount of flexibility for what I could plug away in . An on / off switch controls these main outlets , although this is inconveniently place in the middle of the sockets , so it ’s fiddly to reach without disconnect gadget . Beneath the sockets are the 12V elevator car power and the dual DC5521 12.6V outputs .
On the other side of the battery pack are the USB ports : two USB - A , two fast - commission USB - A and dual USB - blow 100W ( good enough for a laptop ) . Again , these are controlled via an on / off release , although this one is easier to hit .
There ’s a original power switch below the USB port . At the top , you ’ll find an LCD that exhibit the current power attractor , input king and the shelling sentence remaining in both hour ( calculated by how much energy is going out ) and as a percentage .
Internally , there ’s a 1,024Wh battery , which is just over 1kWh of power . On average , UK home use between 8kWh and 12kWh of power per day , so the battery here is a chunk of normal use . If you do want to add more power , you could bring in an additional battery ring .
Adding an special 1,024Wh monetary value £ 749 for the EcoFlow Delta 2 Extra Battery , whereas the Delta Max Extra Battery is £ 1,499 more .
Using LFP battery technical school ( as used in Tesla cars ) , both the Delta 2 and its additional shelling last for 3,000 + charging cycles . That ’s a clod more than the competition , and it means that if the battery was charged and discharged day by day , it would last for more than 10 years .
Charging inputs are on the side of the battery opposite the screen , just above the regular power sockets . As with the River Pro , the inputs are hide under a little dither , which feels a bit more thin liken with the robust soma timbre of the relaxation of the unit .
The standard kettle contribute input sop up power from the briny . With 1,200W of appoint , this battery can be topped up in 80mins , while an 80 % charge takes just 50mins . This was handy when I needed maximum power in the shortest amount of time .
If you ’re on a smart beat with a cheaper off - peak duty , it ’s deserving charging the Delta 2 at night , so you may store the inexpensive force and use it when it ’s convenient .
Alternatively , this power station can be charged via its 12/24V input , so it can be topped up from a elevator car . Likely to be more utile is the solar input , which can take a maximum of 500W ( more on this later ) .
As well as function as a battery , the Delta 2 can be an emergency baron supply ( EPS ) . entrust it plugged into the mains , and if there ’s a king cut , it will switch to battery business leader automatically , keeping primal machine , such as a computer and admonisher , break away .
Just like the River Pro , the Delta 2 can connect to a 2.4GHz internet . Once plume up , the app shows you the current onus ( input and output ) , plus it has switches to toggle the mains sockets , USB ports and 12V elevator car output . Using the app also gives a few extra features , such as control over the quarry cathexis level and the run full stop at which the Delta 2 will stop output power .
Solar Charging
It ’s not always possible to discover a power plug , but with a solar panel input , the EcoFlow Delta 2 can be charged almost anywhere . This tycoon place can work with one or two 220W solar panels ( EcoFlow I be £ 549 each ) or the orotund 400W ( £ 999 ) , which I have on revaluation .
The 400W control panel is a animate being of a machine , close down into a very gravid carry grip . At 19 kilogram , the solar panel is heavier than the Delta 2 itself .
This dish also do as a kickstand , keeping the four panels at the right slant to pluck up sunlight .
I needed a mass of blank to get the panel lay out : at 236.5 cm wide-cut , the 400W solar panel is about half the width of my terraced garden .
Connected up on a shining and sunny day , the solar instrument panel peaked at 295W , which would shoot down the stamp battery in less than 4hrs . However , when the sun went behind a cloud , the solar input dropped to just 31W , and a full charge would have taken about 34hrs .
Based on this , the solar panel is far more useful in the long summertime months than in the short winter days , especially when it ’s often clouded . Still , for those who love bivouacking or are looking to go off - grid , the 400W panel is big and quite expensive , but it does give the best chance for fully topping up the battery by from mains power . That in itself could make it a suitable rise .
Performance
I put the EcoFlow Delta 2 through a range of tests to see what it ’s capable of . First , I load it up with my telecasting setup : a 55 - inch OLED TV , aSonos Raysoundbar and a Sky Q Mini box seat . All in all , I could have had about 8hrs of viewing on a single thrill .
I watched mental object for a few time of day , then rib two lots of umber beans using a home roaster and flux three lots of bread in aThermomix TM6(all of this was over a time period of a few days ) . The Delta 2 managed to cope with all of it on a single charge , with some power even leave over .
With less demanding applications , 1kWh will go a long way . harmonise to Ecoflow , it ’s 31hrs of a 10W light , 16 charges of a 60W laptop , 89 charges of a typical headphone , and up to 32hrs of a distinctive car fridge .
Of course , stick something more mightiness - athirst into it , such as a 1,800W grill , and there ’s just enough power to get about 30mins of cookery time ( quite possibly enough to do something unsubdivided at a pinch ) .
Pair the Delta 2 with a more gentle smoke , such as theDe’Longhi Capsule Desk , which draws about 350W , and there ’s enough for about 3hrs of heat energy on full power , which could be sufficient for warming a dusty tent or campervan .
At its 3,000 charging cycles ( to 80 % mental ability ) , the Delta 2 will have put in about 3,072kWh of power . At its current price , this works out at a toll of 35.7p per kWh stored , plus you have to yield for the power that goes into it . On a stock capped tariff of 34p per kWh , 1kWh of electricity would be 69.7p to both generate and store .
That ’s a bit of an oversimplification , as after 3,000 charge wheel , the Delta 2 will still hold 80 % of its rat capacity , but it will correct from there . Overall , assuming you kept using this mightiness station at reduced capacitance , the cost per kWh would fall , but my figures are still a useful comparability .
Take the EcoFlow River Pro , for illustration . This battery will last for 800 hertz until the capacity is 80 % of its initial evaluation . That ’s a full powerfulness of about 576kWh , so the cost of stack away each kWh is £ 1.29 . The longevity of the Delta 2 compensate dividends over its biography , peculiarly for heavy user .
impart in the solar panel , and for the rated 3,000 cycles , the Delta 2 costs an additional 31p per kWh , although this is take over you ’d exchange the instrument panel when it got through its 3,000 cycles . In realness , the solar jury will keep work , but , again , these figures earmark an even equivalence between unlike devices .
Compared with rival product , these figures are pretty good . The similar Jackery Explorer 1000 ( 1kW ) is more expensive , yet it can manage only 800 cycles before it hits 80 % capability . That ’s a lot less than the 3,000 cycles on offer with the Delta 2 . Over its cycle rating , the Jackery Explorer 1000 costs about £ 1.31 to store each kWh .
Overall , this pee-pee the Delta 2 a good - value choice for storing power and using it where there ’s no mains electricity .
