The 21700 format is larger than the 18650, and the P42A's 4200mAh typical capacity is higher than many standard 18650 cells. The 30A continuous discharge rating makes it suited to compatible devices that draw a lot of power. Check that your device accepts 21700 flat-top batteries before you buy, as this cell will not fit devices built for other sizes.
