The Yocan B-Smart is a slim pen-style 510-thread battery for cartridges, with a 320mAh cell, adjustable voltage and a 10-second pre-heat. It is small enough to sit in a pocket and simple enough for daily use. Against rival pen batteries it trades a bigger battery and digital display for a compact, button-free feel. Owners of small 510 carts tend to like it for on-the-go use; heavy users will notice the modest capacity.
