There are three colors you can choose from: black, blue or pink, and it comes only as 900 mAh, where with a Triton kit you can only get 400 or 650 mAh. (The mAh rating is essentially the size of the battery and more capacity; though they will all operate – or function – at the same voltage for usage).
This option is nice if you want more vape, or to fine tune, as e-juice varies, and you can get it just right. There’s a dial on the bottom that allows you to set the voltage between 3.3 and 4.8 volts. 3.3 seems about the same as the standard 400 and 650 battery for vape, and 4.8 is a substantial difference.
When I went up to 4.8 I almost choked since there was so much vape on the first pull, but it is a great option for refining your vaping, and then the 900 mAh will last quite a while.
