This shits driven me nuts for years. Rechargeable flashlights rated in milliamp-hours?? What the fuck is that? Like they said, it's marketing bullshit so you get tricked into buying something that sucks.
But GOD FORBID WE REGULATE ANYTHING RIGHT??
I guess they could still lie about watt-hours, but buying anything based off of the reported mAh capacity is a crapshoot.
Ended up with a clearly fake 18650 in my collection. Weighs way less than an older 2200 mAh one but it's label says 9900 mAh. Again, it's an 18650.
The culprit:
Any 18650 with a rated capacity of more than 4Ah is a fake. They will usually be very low capacity. The low weight and the hollow sound when you tap on it is good indicator of that too.
There are a number of reputable sites for buying 18650 cells. Stay away from Amazon and Aliexpress, they are full of fakes.
