Verdict
The Bluetti AC70 is a sensibly luggable business leader supply with more than enough zing to deal with camping and other portable use . It ’s a picayune less convincing as a backup equipment for the home , where its limited end product business leader and modest battery storage conspire to make it too weak for more demanding covering . Still , it ’s stable , quiet , and quick to shift from mains to bombardment power , all of which make it a good choice for indorse up a home office or aesculapian machine such as a CPAP auto . It ’s not risky value , either .

Key Features
Introduction
TheBluetti AC70 is a light to intermediate - duty battery power station for the home , or for choke up around on a camping trip . It ’s not especially succinct , but at 10.2 kilogram it ’s potential for an able person to carry it some space – there ’s a vast moulded handle to help with that .
This power station proffer most of the feature you ’re likely to need away from house . There are AC embrasure for main - power train , plus four USB ports to cover a range of estimator , tablets , phone and other devices . you’re able to recharge from mains power when it ’s uncommitted , or top up in the railway car when it ’s not . There ’s also an adaptor for connecting portable solar panels .
At 768 watt hours ( Wh ) , the AC70 stores roughly enough electrical energy to power a electric refrigerator deep freezer for 8 - 16 hours , or a low - energy lamp for four day . It can deliver up to one kW ( kW ) of mains power , which is enough for the superlative demand of games console table , potent computer , televisions , and even some kitchen appliances .
Design and features
This mightiness post is a very similar sizing to theAnker SOLIX C1000 , but it ’s lighter thanks to the fact it ’s pack with fewer batteries . Still , it ’s about as handsome and impenetrable a machine as you ’d want to lug around over any space . While I ’d have no job get it across a quaggy bivouac , I would n’t need to trek up a mountain with it like the miserable models in Bluetti ’s promotional shots .
With a peak mains output power of 1kW , this exponent supply is n’t desirable for demanding gismo like washing machine , and some microwave and coffee makers will be beyond its capabilities , too . The same could be truthful for kettles , but for an cunning ‘ Power Lifting ’ modal value , which lets the AC70 run certain machine that would otherwise be well beyond its limits .
This mode , compatible only with straightforward heat devices that are n’t too fussy about their electrical energy connection , limits the production voltage so that the attached gadget does n’t draw more than the provision ’s maximum . It ’s limited to devices place at 2,000W or below , which still rules out most timpani .
The AC70 is n’t the best packaged mightiness supplying I ’ve test . It ’s well served for USB ports , with two 12W USB - A slot , and two 100W USB - hundred connections , but some user might want more than two briny sockets on a machine in this course . More importantly , its UK plug socket are heap on top of each other , with the top one inverted .
That ’s ok – helpful even – if you ’re connecting a gimmick placed behind it , but if you ’re plug in an oversized adaptor such as some NiMH battery chargers , it could mist the second interface . It ’s also funny that there ’s no twinkle built in , give this gimmick is chiefly focalize on encampment and other amateur use .
rumble aside , there ’s tidy sum to look up to about this power supply . It feels rugged and chunky . Every port is clear label with its maximum rating , which is a helpful way to prevent exploiter unknowingly overcharge it . reasonably , the DC input and every output port are on the front dialog box , with only the briny comment and grounding connection on the right side .
The AC70 also has a utile exhibit , showing the electric battery ’s Department of State of charge in the midsection , with a circular charge indicator to show whether the power supply is charging , discharging , or neither . Arranged around it are four declamatory numeric displays to show the incoming and forthcoming DC and AC power .
Various indicator show which feature are active , while there ’s a countdown timer to show you how long before the assault and battery is charged or depleted , based on your current employment – every powerfulness post should have this . There ’s lots of info on this display and it can await too busy – it ’s a shame the DC and AC power figures default to 0000 when they ’re still , rather than but disappearing .
you’re able to also link up to the AC70 via Bluetti ’s app . I could n’t find instructions for how to do this , so it ’s as well that it ’s trivially well-heeled : tap + in the app , then scan the QR code stuck on the AC70 and its user manual . Once connected over Bluetooth , the app duplicates much of the data seeable on the equipment ’s screen , but you may also hollow into the options to configure the charging and Power Lifting modality .
Helpfully , you may also tweak this power post ’s Eco mode , which switches off the DC or AC outputs if they ’re not being used . That ’s a good way to eke out a battery electric charge if , say , a connected TV goes into standby modal value , but on other power stations it can intend that the plug gets pulled on depressed - power devices . Crucially , this can let in medical equipment like a CPAP political machine . you could handicap the DC and AC Eco modes independently , or configure the closedown time and power doorstep for each .
Charging
The Bluetti AC70 bid a range of charging options . Connected to the briny , it ’ll consume about 450W in its standard charge manner , giving a claimed recharging time of two hours . There ’s also a turbo mode , capable of an 80 % charge in 45 minute of arc , and a full charge in 90 minutes , along with Silent mode , which is assign to take four 60 minutes .
In my testing , the AC70 needed two hours and 13 minutes to amply reload in Standard modality , consuming 892Wh . Assuming that this exact its 768Wh barrage fire from fully fagged to fully charge , that equal to a good efficiency of 86 % . Turbo bear down completed in 86 minutes , wipe out 901Wh , while silent recharging consumed 925Wh over three and a half hours . oddly , the fans ran throughout , although they were very hushed .
you could also charge the AC70 via its DC input , using the supplied in - car and solar panel adaptors . Car charging tops out at 120W , so you ’d only get a full battery after six and a half hours of driving . The AC70 will take up to 500 Isaac Watts of DC input so , in ideal weather condition and with 500W of solar panels , you ’d reload in just over 90 minutes . More realistically , a solar input help you strain the run time of a battery magnate place , keeping you off - gridiron for tenacious .
The AC70 supports appoint from both DC and AC origin at the same metre , but it ’s limited to a 1,000W uttermost across the two . It also has pass - through world power , letting you apply it while it ’s charge . With the maximal 1,000W output connected and AC tear set to Turbo mode , the AC70 drew a maximum of 1,300W from the mains . That means that , as with most power station , the AC70 will charge more slowly if it ’s also power a heavy lode .
Performance
I always test assault and battery tycoon stations at their maximal specified power output , which in this case is 1,000W ( 1kW ) . I connected the fully charged Bluetti AC70 to another power place configured to level at that rate , and let it to to the full complete its shelling . This took 40 minute of arc , over which time it provided 643Wh of electricity . Again assuming that the 768Wh battery kick the bucket from full to completely empty , that would mean an efficiency of 83.7 % .
As I ’ve come to expect from battery power station , this trial seemed well within its capabilities . While the sports fan kick up to a fast speed , they persist astonishingly quiet and very easygoing to live with . Even by the death of the test , the AC70 had warm only slimly at its correct - hand side , and it seemed completely unruffled .
No surprisal , then , that it also had no wobbles when ask to provide a constant 500W , or a constant 200W. In the latter test it discharged a aggregate of 663kWh ( 86.3 % ) , while with a 500W load it delivered 697Wh ( 90.7 % ) . slimly astonishingly , that was the highest image I measured for this gimmick . Battery mogul station usually return their maximum efficiency when supplying DC current , but I measured only 667Wh ( 86.8 % ) over a USB connection with a changeless 60W load .
While the AC70 was more often than not very subdued and easy to live with , my sample distribution did have a more or less odd quirk . On bombardment power , it made a variable , high up - pitched racket when I turned on its AC ports . This normally lasted only for half a second or so , but it reappeared when the AC70 was colligate to the briny and serve loads of below about 100W. I ca n’t say if this was a one - off , unequalled to my instance , but if not it might make the AC70 tricky to live with if you ’re using it to backup very light loads in a noise - sensitive environment like a sleeping room or office .
All of the efficiency figures I ’ve bring home the bacon so far make August 15 about the battery capacity – it ’s much more precise to simply equate the energy you issue with the zip you could later take out . drive the lowest charging and highest yield figure , I measure a best circular - trip efficiency of 78.1 % . That ’s about five percent scummy than the most efficient provision I ’ve measured , but still quite reasonable .
I essay Power Lifting style on my kettle , which is rated at 1.8kW. It churn more slow than common , but make out without incident . My main world power meter report it was using 976 watts , supply at 182 volts – standard UK main voltage is 230V.
Bluetti says the AC70 can flip to its battery within 20 milliseconds of losing mains power , which is in - line with most other portable power station . That ’s not as firm as a dedicated uninterruptible power supply ( UPS ) , but it was fast enough to prevent my situation personal computer or NAS crashing during a simulated power cut . One matter to note is that , in common with other domesticated mightiness supply , there ’s no warning bell to let you know when the AC70 is nearly out of exponent .
This is quite a keenly priced gadget , and it ’s backed up with a five - year warranty . Bluetti say that its batteries will put up 3,000 heraldic bearing cycles before dropping to 80 % of their original capacity . Assuming linear degradation , the AC70 could store around 2730kWh in 3,000 cycles , which equalise to 31p per kWh hive away . That ’s very competitive for a machine with relatively modest storage . I should bespeak out that the AC70 should bear on work even after this point , just with a falling reposition capability .

Should you buy it?
The Bluetti AC70 has enough tycoon for weekends off , or for light source to intermediate backup responsibility in the home . It ’s in general subdued , and seems very stable , too .
The Bluetti AC70 is n’t the best packaged power place we ’ve tested , and it ’s a shame it does n’t have a better mains embrasure layout , or a progress in luminance .
Final Thoughts
The Bluetti AC70 offers more than enough depot and end product for trips into the wild , and its power to take solar and car inputs could help you outride off - power system for longer than just a weekend . It ’s a disgrace , then , that it ’s missing a encampment light , and that it could n’t be a picayune more thickset .
In the home , it ’s a small short of puff to make the ideal power backup machine – and its mains socket configuration could be a act limiting . That said , its low racket and moderate capacitance could make it complete as a UPS to help office or aesculapian equipment ride out a clean important magnate cut . However , if you require more ports or might , consider the Anker SOLIX C1000 , or theJackery Explorer 1000 Plus .

FAQs
It largely depend on how often it ’s used , and how much of the barrage ’s capacity you exploit . Bluetti insure the AC70 for five years , and says its battery will still be able-bodied to salt away 80 % of its original capacity after 3,000 cycles – that ’s equivalent to eight years of one full rush / waiver cycle a daylight .
Typically , yes . The AC70 certainly has more than enough laggard to great power even a large boob tube . Always discipline the maximum magnate consumption of your TV ( and anything else you want to connect ) against the maximum AC output of the power station you ’re design to corrupt .
Refrigerators vary , but most modern instance use only a couple of hundred watts . In possibility , then , any magnate post capable of assemble your electric refrigerator ’s power demands will die hard it . The AC70 will certainly power any domesticated fridge freezer we ’ve encountered . Things get more complex when you study how long you might require to execute the fridge for . A modern fridge freezer use one or two kilowatt hour per daylight , so you might only get about eight hour ’ service from an AC70 . If you live somewhere that sometimes has stretch force cuts , you might need a gadget that stores importantly more Energy Department .
