|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1Jackery$1,499 | rated 2200 W, 4400 W peak, 2042 Wh capacity, claims 41% lighter and 34% smaller than a typical 2 kW power station, 30 peak dB charging noise, 0 to 80% in 66 min AC fast charge, full charge in 102 minutes | 39.13 lb | 60 Hz, 119.74 V, about 9 W difference between the two energy meters | 45.4 dB, second quietest of all 9 units behind EcoFlow's 37.8 dB | made easy work of one light and the compressor; with two lights already powered up, threw in the towel early (failed the two-light plus compressor test) | performed better than its 2,200 W rating for several minutes; ramped to 2,600 W demand which was too much and it powered down; finished second place overall in this test at 2,401 W behind DJI's 2,641 W | rated 2,042 Wh (6 Wh less than Dabbsson's rating); lasted close to 75 minutes and produced 1,780 Wh, an efficiency of 87.2% (third place efficiency behind Dabbsson 91.8% and EcoFlow 87.9%; second place in raw watt hours produced behind Dabbsson's 1,880 Wh) | fastest raw charging wattage of all 9 units tested, 1,701 W per the Jackery and 1,738 W per the analyzer; finished charging in 1 hour 20 minutes, requiring 2,220 Wh for a full charge; came out on top of the apples-to-apples charging-efficiency comparison at 22.3 usable watt hours per minute of charge time | performed very well with only a brief light flicker; computer stayed powered on | 89% remaining after 15 hours, the best of all 9 units tested | came out on top with the highest estimated run times overall; example given, approximately 29.2 hours to power a full size refrigerator | not tested | not tested |
| 2EcoFlow$699 | narrator states 'It's rated for 1024 W. It can handle up to 1800 W' at introduction, but later in the max output test says 'The EcoFlow is rated for 1,800 W' and it performed very close to that rating at 1,801 W; these two statements of its rated wattage are inconsistent, kept verbatim rather than resolved. Also claims 7 times faster charging (0 to 80% in 50 min, 0 to 100% in 80 min), solar charging up to 500 W, life cycle over 3000 cycles | 26.5 lb | 60 Hz, about 119.4 V | 37.8 dB, confirmed later in the recap as the quietest of all 9 units tested | AC outlet initially powered itself down when the lights were plugged in, then powered the lights once the AC outlet was re-enabled; with one light it was struggling, around 106.25 V and 1,805 W (right at its max rating); it did kickstart the compressor but voltage dropped below 100 V which the narrator calls way too low; not clearly tested with two lights in the transcript | rated 1,800 W, performed very close to that rating at 1,801 W, voltage dropped quickly as demand increased further | rated 1,024 Wh, barely reached 900 Wh and powered down at just over 38 minutes; finished third place in absolute watt hours produced, second place in efficiency at 87.9% | showed 1,328 to 1,342 W on its own display versus about 1,336 W on the tester; needed about 5 minutes longer than OUPES to reach full charge, finishing at 57 minutes 20 seconds; took 1,180 Wh for a full charge | performed well with just a very brief light flicker; computer did not power down | 82% remaining after 15 hours, described as by far the best yet at that point in the video (before Bluetti, Dabbsson, and Jackery were tested) | not tested | not tested | not tested |

| 6Bluetti$799 | rated 1,800 W or 3,600 W surge; total capacity stated as 1,024 Wh at introduction, but later restated as 1,152 Wh in both the battery capacity test and the charging test sections (internally inconsistent, kept verbatim, the 1,152 Wh figure is corroborated twice); claims smaller/lighter design at 25 lb and 17 L, full charge in 70 minutes, up to 11 devices at once | just under 25 lb, described as the lightest yet at that point | very close to 60 Hz and just over 120 V; about 11 W difference between the two meters, around 119.4 V and 60 Hz under light load | 48.1 dB, confirmed later in the recap as third place, behind EcoFlow (37.8 dB) and Jackery (45.4 dB) | unable to kickstart the compressor with just one light; tried a second time and gave up early again; unable to power the compressor at all even without a light drawing current (total failure on this test) | wasn't able to kickstart the air compressor, but performed well powering a space heater and lights at around 2,103 W | rated 1,152 Wh per the battery test narration (see spec inconsistency note); gave up sooner than EcoFlow at close to 36 minutes, producing 850 Wh | showed around 1,198 W versus about 1,214 W on the energy use meter; finished charging in 1 hour 8 minutes; took 1,130 Wh to charge | performed well, narrator did not even see a light flicker, the best UPS result described in the video | 84% remaining after 15 hours, performing better than EcoFlow's 82% at that point | not tested | not tested | not tested |
| 7DJI Power$799 | claims handling up to 2,600 W, 0 to 80% recharge in 37 minutes, marketed as 'a really quiet generator at only 26 decibels', dual 140 W USB-C charging ports, UPS capability with a 10 ms switch time, 1,024 Wh total capacity | 31.24 lb | right at 60 Hz and close to 119.5 V without a load | measured at 55.7 dB, notably higher than the marketed claim of 26 decibels (kept both figures verbatim, not reconciled) | easy kickstart with one light; also powered up with two lights but powered back down after 8 seconds (partial pass, degraded under sustained two-light load) | produced 2,746 W for a few seconds before an alarm triggered; the alarm cleared around 2,641 W; came out on top of the max continuous output test at around 2,641 W, ahead of Jackery's 2,401 W | rated 1,024 Wh, same as EcoFlow; powered down at 36 minutes 38 seconds, producing 870 Wh | charging at 1,447 W per both the energy use meter and the unit itself, faster than Bluetti; finished in 53 minutes 17 seconds, about 4 minutes behind Anker; took 1,170 Wh to charge | brief light flicker but the computer did not power down | described as having a pretty high idle consumption rate at 69% remaining after 15 hours | not tested | made very easy work of powering up the lights, settling close to 119 V and still 60 Hz; within 1 W of the energy use meter | not tested |

How it was tested
- idle voltage/frequency bench check, no load
- powering three halogen lights (roughly equivalent to over 150 LED lights), wattage/voltage/noise under light load
- noise level test in decibels under light load
- kickstarting/powering a 33 gallon air compressor already at 90 PSI plus up to 3 halogen lights, surge capacity test
- maximum continuous output wattage test, ramped via fan speed controller and space heater until overload
- total battery watt hour capacity and runtime test, drained via halogen lights with a timer
- recharge time and total watt hours to full charge, 3 units charged simultaneously per group
- sine wave cleanliness ('dirty power') test under a drill load
- uninterruptible power supply (UPS) test, computer plus light with wall power disconnected
- 15 hour standby idle power drain test
- USB-C port output wattage spec check
- estimated appliance runtime calculations (e.g., full-size refrigerator)
“in my opinion, the best overall power station is definitely the Jackery. It also earned A's in every category and it has about twice the watt hour capacity. Even though it is a very good power station, it's also very expensive.”
