Mini 500mAh 510 Cartridge Battery - ION

A step up from the Slim, the ION Mini trades a marginally thicker body for a meaningful jump in session capacity—enough to get most moderate users through a full day without the mid-afternoon recharge anxiety that the 320 mAh Slim can't quite avoid. The "Mini" branding is strategic: it promises customers that the size increase over the Slim is minimal while the performance increase is substantial, making the upsell conversation effortless at the counter. For customers who tried the Slim and liked everything except the battery life, the Mini is the natural re-purchase that keeps them in the ION ecosystem. The still-compact pen form factor remains genuinely pocket-friendly, and the addition of a preheat function adds genuine utility that the Slim model skips. Retailers who display the Mini next to the Slim with a "more power, same pocket" message move the upgrade consistently.
