Hey SMOK, stop playing ratings games! https://ift.tt/2HBKkhT

SMOK has released the V-Fin 160W internal battery mod claiming it has an 8000mAh rating. Mike Vapes reviewed it (link below) and was kind enough to send me one for testing and SMOK’s claim is preposterous.

The two cell battery pack inside clearly shows that it uses 12.21Wh cells. Using the marked 3.7V nominal voltage that means each is only 3300mAh. (12.21Wh / 3.7V = 3.3Ah).

My testing confirmed this as the pack delivered 3296mAh at 0.5A down to 3.0V per cell (6.0V for the pack). Two 3300mAh cells in series means it is a 3300mAh 8.4V (7.4V nominal) pack.

Even if we use the concept of “equivalent mAh” this means it only has, roughly, the same running time as a single 6600mAh cell.

Not only did SMOK play an “equivalent mAh” ratings game by not telling us they were doing it but they falsely raised the ratings of their 3300mAh cells to 4000mAh.

SMOK, we have enough problems with exaggerated ratings for the external batteries we use. Why did you exaggerate the capacity rating for these internal cells?

You had a chance to use their true rating and tell us about “equivalent mAh” to help educate the community. You could have easily told us about how a regulated mod using two smaller cells can run just as long as one with a larger single cell. This would have given you a huge “6600mAh” number to use in your marketing.

But instead you just decided to exaggerate the rating. Why?
