AC outlet / drill soft start test
- 1Jackery111.1 V
under the 250 W heat lamp load, watt meter closely matched the reference energy meter; more than enough power for the drill, reaching full RPM in about 1 second
- 2Bluetti120.3 V
under the heat lamp load, notably higher than most other brands' roughly 110 to 112 V; watt meter closely matched the reference meter; reached full drill RPM the fastest of all brands on the first attempt, in about half a second, but the dashboard showed an overload warning on a second attempt; using the drill's adjustable trigger for a soft start worked fine
- 3VTOMAN110.8 V
under the heat lamp load; watt meter was off by about 10 W, the largest discrepancy of any brand tested; drill reached full RPM in about half a second, tied with the Bluetti for fastest
- 4GRECELL110 V
at around 223 W under the heat lamp; drill reached full speed in only 1 second; built-in watt meter accurate within 1 W of the reference tester
- 5EBLabout225 W
and 110.5 V under the heat lamp, about the same as the Bailibatt, with roughly a 6 W discrepancy between meter and tester; best drill result recorded up to that point in the video at 0.7 seconds to reach full RPM
- 6ALLWEI112.1 V
about 1.5 V higher than the Bailibatt; watt meter (mounted upside down) measured 2 W different than the reference tester; the drill test FAILED, the unit powered itself down when the drill was activated ('said no way and it powered itself down')
- 7Anker
skipped entirely; the unit has no AC outlet to test
- 8ZeroKor
FAILED the heat lamp test; rated for 300 W but could not power the 225 W heat lamp; also FAILED the drill test, powering itself down when the drill was activated quickly even using the drill's variable speed trigger for a soft start attempt
- 9Bailibatt
outlet meter close to the multimeter reading at 112.7 V; 225 W and around 110.5 V under the heat lamp; drill test passed with a built-in soft start, about 2.5 seconds to reach full speed
USB-C charging test
- 1Jackeryjust over60 W
at 20 V, right on target for its 60 W rating; 14.62 W at 5 V; a reading described as 25.75 W 'at 12 volts' called right on target, but the transcript then immediately says the Jackery 'is not cooperating with the analyzer for the 12 and 20 volt settings,' a direct contradiction in the same passage; kept both statements verbatim and flagged rather than resolved
- 2Bluettijust over92 W
performing as well as the Anker; 14.48 W at 5 V, 27.1 W at 9 V, 36.61 W at 12 V, 94.56 W at 20 V, described as almost as good as the Anker
- 3VTOMAN56.52 W
charging the power bank; transcript states it 'is not cooperating with the analyzer for the 9, 12, and 20 volt settings,' so those readings are incomplete and omitted rather than guessed
- 4GRECELL
right on target at 60 W at 20 V for its 60 W rating; 13.57 W at 5 V, 26.89 W at 9 V, 33.26 W at 12 V, 60.5 W at 20 V, the best result recorded up to that point in the video
- 5EBLabout29 W
charging the power bank, about half the rate of the Grecell and Allwei; 14.9 W at 5 V, 27.8 W at 9 V, 37.73 W at 12 V, 64.55 W at 20 V, the best result recorded up to that point in the video
- 6ALLWEI
rated 60 W but came up short at 56 W; 13.63 W at 5 V, just over 24 W at 9 V, just over 34 W at 12 V, almost 60 W at 20 V, about the same performance as the Grecell
- 7Anker
by far the best result of all brands at 92 W charging the power bank, consistent across all of its USB-C ports; charging three devices simultaneously delivered 86 W, 95 W, and 32 W for a combined 213 W; single-port voltage sweep: almost 14 W at 5 V, just over 24 W at 9 V, 38.1 W at 12 V, 97.3 W at 20 V, the best result recorded up to that point in the video
- 8ZeroKor
not applicable; this unit has no USB-C port
- 9Bailibatt17.5 W
at 12 V; powered itself down after reaching 14.7 W at 5 V; powered itself down at 27.1 W at 9 V; powered itself down again at 28.1 W at 12 V (a second, different 12V reading than the first); not able to charge at all at 20 V; the weakest USB-C performance of any brand tested

- 2Bluetti
overload protection triggered at 614 W against a 600 W rating

- 4GRECELL276.5 W
against a 330 W rating, described as the extra weight not helping
- 5EBL260 W
against a 330 W rating, described as the least amount of all the brands tested

120V wall charging speed
- 1Jackeryaround91 W
can be charged while powering a device
- 2Bluetti

can be charged while in use
- 9Bailibattaround32 W
allows the unit to be used while charging, but only if the load being drawn is under 32 W
All measurements (4 more)+
Cooling fan noise
- 1Jackery47.4 dB2nd
the quietest of all brands at the time it was measured, and confirmed as second place overall behind the Bluetti (45.7 dB) in the final fan-noise recap
- 2Bluetti
measured around 47 dB during the intro section, but cited as 45.7 dB and first place (quietest of all) in the later fan-noise recap; both figures kept, discrepancy flagged rather than reconciled
- 3VTOMANaround57.8 dB
- 4GRECELL49.1 dB
quieter than the Bailibatt; finished third in the fan-noise recap
- 5EBL58.2 dB
the transcript's description here reads 'is allowed as yet at 58.2 decibels,' an apparent caption garble, most plausibly intending 'is the loudest yet'; kept close to verbatim and flagged rather than rewritten with confidence
