“Very compact, convenient micro USB charging, easy to adjust with the 'Top Twist' ring and easy to read voltage markings. I have owned several of these over the years and they always have worked good, lasted well, and they have just 'Improved' them over time.”
“it's the only vape battery i use now. I bought the 1100mah battery as as a backup and to alternate use with the 650mah battery. The variable voltage definitely comes in handy to customize performance depending on what type and quality of cart i'm using at the time. I highly recommend these Cartisan batteries!”
