Verdict
Bluetti ’s AC240 is almost unequaled in combining go - anywhere power , with use - anytime water and dust protection . It ’s a convincing mobile power post for regular campers , mobile workers or sauceboat owners . It ’s enhanced with a good ambit of feature , and it execute well on our run . That said , it does have a couple of drawbacks . The first is that it ’s very bragging , and so sullen that you ’ll need a trolley to comport it any distance . The 2nd is that it ’s importantly more expensive than an equivalent Cartesian product without the sealing . If you do n’t need to take it anywhere , or you’re able to populate with less power , there are better value choice .
Pros

Key Features
Introduction
We ’ve examine a lot of bombardment office stations , but Bluetti ’s AC240 is the first that ’s designed to withstand a wide compass of outside conditions . It ’s IP65 rated , mean it ’s secure to use around dust and even abject pressure green of water . In possibility , that cover you for anything from a 24-hour interval on a flaxen beach , to a miserable winter deluge . It should also intend it ’s desirable for use in dusty oeuvre areas that would mumble up the fans of lesser product .
The Bluetti AC240 is a fairly wakeless - duty supply , provide up to 2400 James Watt of mains electricity . That ’s enough to power most menage contrivance or appliances , save the most powerful heaters , driers or kettles .
It can store up to 1536 watt - hour ( Wh ) of power , which is substantial , but not quite as much as I ’d usually expect in a twist of this sizing . Bluetti says the batteries will still keep on 80 % of their original capacity for at least 3500 bursting charge cycles , and it back this up with an splendid six - twelvemonth warranty .
This big power post weighs 33 kilogram , which gives the lie to promotional shots that show it in various rugged out-of-door location , as you ’d call for a trolley to carry it any real length . If you take sealing , but do n’t involve as much power , theBluetti AC60is smaller and more portable .
Design and Features
Water and electronics do n’t mix well , specially if there are powerful batteries involved . Accordingly , it ’s not surprising that this is the first power post I have test that claim to be urine resistant . Bluetti has n’t just fitted water - tight bungs to one of its even devices , though : it ’s design the AC240 so that its bombardment and other component are isolate at bottom , and theoretically near - impervious to water supply or dust .
This point of aegis comes at a toll – literally , as the AC240 is more expensive than corresponding non - waterproofed power stations . And while it can hive away 1536Wh of electrical energy it ’s at least as big as regular alternative adequate to of storing 2000Wh , such as theBluetti AC200L.
This power station weighs in at a hernia - inducing 33 kg – more than a 2000Wh machine , despite having only three - quarters of the battery . This forces a bit of a via media . While the AC240 is almost a go - anywhere power station , really getting it anywhere could be an issue . It ’s firmly even for two people to bear it far , so you ’d need a tramcar for any meaning trek .
With this in mind , this mightiness station makes more gumption when look at as a conciliatory and highly protected power supply for damp or moth-eaten environments like wine cellar , unpaid vehicles , or even boats .
In this role , its peak turnout king is enough for a modern washing automobile , dishwashing machine or oestrus - heart drier , although its 1.5 kW - hour ( kWh ) of stash away energy is n’t enough to get through longer or hotter lavation cycles/second . If that ’s a problem , you could expand the AC240 with up to four Bluetti B210 batteries , which also have an IP65 rating . Each consider a further 28 kg , and add 2.15kWh of electrical storehouse .
Bluetti has n’t skimp on this power supply ’s output embrasure , which are all on the front panel . There are four UK plug socket , which together with partake in the maximal 2400W output . Additionally , there are two 100W USB - C port wine , and two USB - A socket rated at 18W each . To the left you ’ll find a 12V/10A cigarette easy - style car port , plus a 12V/30A RV connective .
On this power place ’s right hand panel you ’ll retrieve a thrust - set connector for its AC power atomic number 82 , along with a DC input that support up to 1200W from solar panels . There ’s also a port for connect another AC240 in analogue , potentially providing a system with double the output power and storehouse . Uniquely , this power station has a bleed valve , used to help manage imperativeness within its sealed internal part .
Every port is protect by a safe spile or cover . While I ’ve sound off on previous Bluetti devices that the AC great power bungs can obstruct mightiness chew , here they have an improved , thinner innovation that ’s less of an number .
One important limitation is that inserted hoopla or connectors are n’t protect from the element , so while the AC240 might survive a rainstorm , it seems foolhardy to really use it when it ’s soaked .
One further thing to note about this – and every other Bluetti business leader station I ’ve tested – is that every port is clearly labelled with its maximal capabilities . That ’s great for serviceability , but also for prevent overloading , as you do n’t postulate to repeatedly search the net or manual for the power supply ’s specifications before plug machine in . I wish well every power post had the same .
you’re able to change most of this power station ’s various options through button press , but it ’s far easier to connect via Bluetooth or Wi - Fi and employ the app . This makes it easy to adjust setting such as the charging mode , or fix the consumption levels and clock time below which the power port are flip off in Eco modality .
Charging
The Bluetti AC240 offers the common chain of mountains of charging option . Most merely , you could secure it in and charge it from the mains in Standard , Silent or Turbo fashion . curiously , Standard and Silent are both confine here to the same 800W maximum , which should see a full recharge in around two hour . It ’s deserving noting that the tell 3500 - cycle life apply only if you deposit to Silent mode , which is the most docile on the batteries .
trade to Turbo mode and the AC240 recharges at a breakneck 2200W , which is potential to reduce the bombardment lifespan if you do it in particular often . Bluetti say this mode can get you to 80 % charge in 45 minutes , and in my examination a full recharge adopt only 56 minutes .
you may also charge the AC240 with up to 1,200W of solar baron . Panels are hook up via a add MC4 connector , most commonly found on permanently installed panel , but you may buy XT60 adaptors if you have portable panels that use them . This powerfulness station will charge up from AC and DC sources at the same time , up to a 2,400W maximum . you could use the app to configure selection such as PV Priority , which will only use main power to maintain the minimum charge level you correct . Once it hits that number , any further charging will fall from the solar panels only .
The final charging selection is to use the supplied railway car office adaptor , which is set to just 120W. This makes for dull charging – in this fount , you ’d demand to drive for 13 hours before full charged .
I measure the AC240 ’s functioning in all three of its mains agitate modes . harmonize to my force meter , a full recharge used 1,679Wh ( 1.68kWh ) in understood modality , 1.69kWh in Standard , and 1.73kWh in Turbo . feign each mission took the batteries from fully empty to entirely full , Silent fashion equated to an efficiency of 91.5 % .
Performance
We test every power place across a wide kitchen stove of constant world power loads , checking for stability , and measuring how much magnate is render before the batteries are exhausted . In common with the other Bluetti devices I ’ve tested , the AC240 had no problem with sustain anything up to and include its maximum 2,400W load , and remained quite quiet even at full power .
The AC240 was at its most efficient when supplying a mediocre load . It managed to supply a level best of 1.36kWh of electricity when providing 1000W of never-ending might , equating to a strong 88.5 % efficiency . The output drop a fiddling to 1.3kWh at maximal load , an efficiency of 84.4 % . The miserable AC supply I mensurate was 1.24kWh for a constant 200W payload : an efficiency of just 80.7 % .
Some king station are more efficient when render DC power , but like other Bluetti examples I ’ve tested the AC240 was n’t . I connected a constant 60W load to one of its USB - degree centigrade port , and it supplied 1.14kWh before the battery was sap – that ’s an efficiency of only 73.9 % .
That said , it ’s more informative to compare the ability you put in directly against the might you later take out . Using my low-down consumption figure for charging , and the highest power production I recorded , the AC240 managed a serious round - slip efficiency of 81 % – among the better answer I ’ve seen . Its good DC round - stumble figure was only 67.6 % , though .
The AC240 is very tolerant of short - condition overloading – it can add up to 3000W for up to two minutes . If even that is n’t enough , its Power Lifting mode limits the supplied current and voltage to let you run over - specified twist such as a kettle , but it ’s not suitable for more advanced loads like a lavation auto .
The Bluetti AC240 was n’t quite flawless during my tests . straight off after have its bombardment drained by a tax 2kW load , its fans were still function quite intemperately when I switch it off . Five hour later when I need to charge from the main , the battery overheat indicator add up on and the AC240 would n’t bill . Despite being over - temperature , the devotee did n’t restart to help cool it down , and I had to wait an hour or so for it to cool .
shit to last for 3500 charge cycles until it reach 80 % capability , the Bluetti AC240 could store 4838.55kWh of power over this period , assuming additive degradation . That works out a monetary value of 37p per kWh , which is quite mellow ; the high-pitched capacity UGreen PowerRoam 2200 be just 25p per kWh using the same metric unit .

Should you buy it?
This power post can withstand almost anything the environs hurl at it . It ’s powerful , put in a reasonable amount of electrical energy , and has excellent upgradeability , too .
This is a very heavy power supply for its warehousing capacity . It ’s also comparatively expensive .
Final Thoughts
If you need an all - weather power post with enough laggard to run a dishwashing machine , the Bluetti AC240 is more or less your only alternative . It ’s brilliantly engineered , apparently impervious to water or debris , and well able-bodied to hold up its rate performance . In possibility that create it heavy for powering a drizzly camping expedition , but its sizing and system of weights could well make this airy unless somebody come in an RV .
That leaves gravy boat , drippy cellars and other damp environments . And here it ’s significant not to overlook that , while the AC240 might be well-chosen in a downpour , it almost certainly would n’t be safe to use it . Few gimmick that plug into mains or USB electricity are waterproofed , and even those that are might not be so while actually tie in . The AC240 might operate on batteries , but remember that – like other AC power station – it ’s still adequate to of have a serious or fateful galvanizing shock .

FAQs
In our view , yes . We ’ve tested plenty of battery ability supplying from both brands , and are yet to award any of them less than 7/10 .
Like most modernistic bombardment power stations , Bluetti products practice lithium iron phosphate ( LFP ) batteries . These can usually wield at least 3,000 full charge cycles before their overall capacity miss to 80 % . In the AC240 ’s case it ’s 3,500 bike . Even if you in full turn on and drain it every day for more than nine years , it should still be able to store 80 % of its stated capacity . If that ’s not reassure enough , the AC240 comes with a six - twelvemonth warrant .
