Whatâs the problem?
Itâs a 26800mAh capacity charger but they call it a 26800 charger, so people searching for a charger for 26800 batteries may come across it. At least Iâm guessing thatâs what heâs getting at.
Precisely. Maybe itâs just a coincidence, but 26800 isnât divisible by any commonly known 18650 battery ratings is it? I donât know, seems at least as plausible as the Disneyâs Frozen/Frozen Disney conspiracy theory. 
It actually does seem like a common mah rating for powerbanks, there a many with 26800mah, and I think I even have one, for some years now.
Man, thatâs a weird coincidence then. Maybe there is some kind of market research behind it. Perhaps 26800 is an aesthetically superior combo of numbersâŚ
Never really thought about it, but yes itâs strange, since they could easily label them as 26000, 27000 or something.
Are you guys for real? xD
Eight of those for 26800mAh rating. Those powerbanks have been sold for years nowâŚ
Time to touch grass guys.
way to do maths! :+1:
Then why do they call the ones with 6 batterys 20000, and not 20100? They could easily get away with labeling the 26800 ones 27000. Or 26000 if they want to be safe.
Touch grass? How is that going to give me cognizance of oddball 18650mah ratings?
Anyway, I was assuming 12 cells but I guess the unit is a little too short to hold 3 rows of 4.
Lol, guys, itâs because airlines have a limit of 100 Wh for li-ion batteries.
26.8 Ah x 3.7V = 99,160 Wh
So this is the largest battery pack you can bring in your carry-on. Thatâs why itâs such a common capacity.
And they have been around before 26800 batteries were a thing.
In my defense, Iâve never been on a plane. This makes sense though.
99.9% of people shopping for powerbanks doesnât even know what a 26800 lithium ion cell is. So there wonât be confusion among them.
26,800mAh capacity powerbanks uses 8 cells, this rating is popularized by the use of Panasonic NCR18650B and LG F1L 18650 cells which are rated at 3,350mAh. 10,400mAh powerbanks back in the day was the top stuff and that capacity was popularized by the use of 4x Samsung 26J, the market later was flooded with fake capacity products with chinese cells all claiming to be 10,400/20,800mAh
This capacity rating is not exact as most powerbanks will not allow the cell to go lower than 3.0V whereas the manufacturer rates the cell based on a discharge test down to 2.5V in perfect conditions at a low discharge rate.
Some models have 3,500mAh per cell rating based on the planned use of Sanyo GA cells, but they ended up using a âequivalentâ cell which has lower capacity.
