Verdict
With its high capacity ( expansible to over 6kWh ) and a maximum power yield of 3100W , the EcoFlow Delta 2 Max can power almost every UK appliance . With profligate charging , the ability to combine solar and AC , and wise energy ascendency that lets you poise the two sources , this mogul station is fast and effective to file . It ’s a little fiddly to carry around , but its fantabulous range of yield and gamy efficiency make it a enceinte option for those that need a lot of exponent on the go .
Pros

Key Features
Introduction
With a 2048Wh battery , four UK major power exit , a maximum power output of 3100W , and a brawny 23 kg weight , the EcoFlow Delta 2 Max is at the limit of portability .
Built for those who necessitate the maximal amount of king on the go , this is a well - sport and long - lasting stamp battery system .
Design and features
While the EcoFlow Delta 2 Max is n’t much big than theEcoFlow Delta 2 , it ’s considerably heavier at 23 kilo vs 12 kg . That ’s because the Max has a much liberal 2048Wh assault and battery indoors , which signify that it can store between a tail and a one-fifth of the average UK home ’s vim usage . That say , the EcoFlow Delta 2 Max double the storage capacity , but does n’t duplicate the weight , which is impressive .
As with other EcoFlow bombardment that I ’ve refresh , the Delta 2 Max has carry handle on either side of its body , so you may sway it with two hands . I more or less favor the lift - up handle that Jackery allow for on its power stations , such as theExplorer Explorer 1000 Plus .
The EcoFlow Delta 2 Max is well - provisioned . On the side with the LCD and primary power clit , there are the USB output signal : two 100WUSB - Cports are capital for modernistic laptops , plus there are two standard USB ports ( 12W per porthole ) and two fast - charge port ( 18W max ) .
Spin the machine around and on the opposite side are the power comment , the four UK power outlets , and the DC outlets . UK mogul socket can be galling due to their size , but EcoFlow has aligned these well , so you should be able to habituate all four of them without a plugged - in adaptor causing an obstruction .
In the default mode , the exponent sockets support a combined yield of 2400W , with a surge military rank of 4800W. Turn on X - Boost , and the power turnout jumps to 3100W , which is more than a stock household spark plug provides . X - Boost wo n’t crop with all equipment , particularly those that have strict potential difference requirements or electromotive force security .
In effect , that mean that you may power any single UK equipment , include a boiler ; more realistically , you ’ll find that you may power multiple high - top executive devices at once , give this power post a immense amount of flexibility .
It can be used as an Emergency Power Supply ( EPS ) , feeding mains power through to its power socket ; in the event of a power cut , the electric battery kick in and takes over within 30ms . For devices reliant on faster switchover times , such as servers and some medical devices , that ’s too long ; for regular household devices , that ’s not a problem .
While a big power output is useful , using high - top executive gadget will drain the battery tight . If you do need more power , then the EcoFlow Delta 2 Max supports up to two extra EcoFlow Delta 2 Max Smart Batteries , each adding 2048Wh of power ; that ’s a totality of 6144Wh of office .
Via the screen door on the front , you could see the current care status ( and any stimulus power ) , plus the current drain and the battery life remaining in arcminute and hour .
Controllable via Bluetooth or Wi - Fi , the EcoFlow Delta 2 Max is compatible with the EcoFlow smartphone app . This gives remote control over the outlets , and sees the same info that the physical LCD shows .
Via the app , you could also control X - Boost , the AC charging speed ( it ’s 2400W by nonpayment , but you may desire to melt off this if you ’re on a low-spirited - power circuit ) , and the charge / sacking limitation ( reducing these can improve battery life if you ’re unforced to give usable capacity ) .
Charging and solar
For mains charging alone , the EcoFlow Delta 2 Max can run into 80 % capacity in just 53 minutes , or it can get a full charge shortly after that . That ’s with child news show if you involve to go out and do n’t have long to top up the stamp battery .
There are inputs for up to 1000W of solar power . Connect the maximum , and EcoFlow says that the battery can be charged in 2.3 hours , although the effectiveness of the sunshine and positioning of the solar panels will make a difference .
Solar and AC tycoon can be compound , using a combining of 1800W AC and 600W solar uttermost . This reduces the 80 % charge clip to just 43 minutes .
Built to be smart , the EcoFlow Delta 2 Max has energy direction via the app for the solar stimulant , where you’re able to prefer to prioritize solar remark to salve free energy , or use more AC stimulation if you want more vigor usable for the barrage .
Charging the battery via AC , I saw that the EcoFlow Delta 2 Max used 2203Wh of might to in full top - up to 2048Wh . That means that the organization draws 107.58 % of the battery capacity , which is very militant and ahead of the Ugreen PowerRoam GS1200 and just ahead of the Jackery Explorer 1000 Plus .
Performance
Using LiFePO4 shelling , the EcoFlow Delta 2 Max has a quote 80 % capacity after 4000 charge and release rhythm . sham that there ’s analogue abasement of battery capacity , this would have in mind that over its spirit , the EcoFlow Delta 2 Max would address 5528.17kWh of baron .
Based on the price of the tycoon station , this works out to a monetary value of 34p per kWh of storage . That ’s about average for a machine of this type , and the price tends to get down if you prefer for a system with a smaller overall capacity .
remark that this price does n’t include the toll of get power into the system , as that could be from a standard electrical energy socket or via an off - peak duty or even via solar panels .
To see how effective the inverter is at convert DC power into AC power , I discharge the barrage using a sports fan heater running at ~1000W. The total measured power output was 1.709kWh , which means the system of rules was 83.45 % effective . That ’s excellent , with wastage down to the inner systems and the transition between DC ( barrage ) and AC ( mains ) power .

Should you buy it?
With four UK ability fire hydrant and a high big businessman output of up to 3100W , this is a power station that can cope with pretty much anything .
If you want something that you may more well carry around , a light system with around 1000Wh of power may be better .
Final Thoughts
The main competition is from theDabbsson DBS2300 , which has a like electrical capacity to the EcoFlow Delta 2 Max . While the Dabbsson is slimly cheaper per kWh stored and has larger 3000Wh expansion batteries , it has a lower stock power output and only two UK power plugs .
Overall , the EcoFlow Delta 2 Max is more flexible with its gamey power output and quicker charging , and it has a better app with voguish energy control condition , too . If you ’re a mellow power drug user and need that Energy Department to be portable , this is a great organization .
