OP had omitted the seller info at the time I commented.
I have never heard of the brand/seller so I look up the info.
Some people seem to feel it's racism/bigotry to highlight when it's a no name seller as it's from China 90% of the time. others could well be shills as you suggest.
Who knows, glad you found it useful though

I received mine today, and I am just testing the Wh/mAh capacity.
Crack the device open, and the internal battery (SDL-606080) uses 4 x 2,500 mAh = 10,000 mAh at 3.7 volts or 2,500 mAh at 14.8 volts.
Fully 100% charge it = 16.6 volts and 0% = 12.88 volts.
Not sure why they used the battery chemistry with 3.7v nominal w/maximum charge to 4.2 volts x 4 = 16.8 volts
Instead, they should use the battery chemistry with 3.2v nominal w/maximum charge to 3.65 volts x 4 = 14.6 volts
Also, you should only use this jumpstart with a battery remaining power below 90% to ensure it is less than 15 volts (prefer 14.6v), or there is a chance it might cause damage to your car's electronics.
Tested yield = 31 Wh / 37Wh assume = 84% efficiency.
The ads listed for 74Wh are a joke. Flase advertising in Povasee
The most important parts of all these jumpstarters are the high-C state battery and the connector plug-in clamp where the capacitor/diode is hidden. Maybe the magic of jump-starting the car lies in the short bursts (ms) of high amps 300-500.
Not this deal, but commenting about these noname brands like someone did earlier as well as your comment. I just returned two branded CARHEV with a similar issue where once at 100% I tested charging a PS4 controller and it barely charged it and took it down by 5% in about 10 minutes.
The first one I recieved was already at 100% so assumed to have been returned and the second was at 0% and took 9 hours to charge completely. I think I'm gonna eat the usual $20 more that Costco charges for the models they carry just in case they wind up sucking. Also reading about these battery packs turning into spicy pillows if left in the car is terrifying so if one is gonna nuke my car while parked, at least have one with a known company versus offshore brands.

I have an older version of this that I bought after watching a review from ProjectFarm on YouTube. It performed really well in his tests and Ive been happy with mine over the last couple of years.
People on this site are so quick to call anything with a non-recognised brand name junk. A lot of junk is made in China. A lot of decent and even bleeding edge stuff is too.
Do research on products before you buy them from any company. Ive gotten junk from "brand names" before too.
