K2 Ultra E Cigarette Battery

With 100mAh more power than our standard K1 e cigarette battery, the K2 battery packs a real punch for something in such a small package. The K2 measures in at just 13mm longer than the K1 standard e cig battery & is similar in length to a superking cigarette when attached to our refills. You’ll find increased vapour production, longer usage between charges* and a longer overall lifetime, all for just £2 more than the K1.

You can charge the K2 batteries with our standard OK USB Charger.

Please note: as this e cigarette battery is more powerful, you may find that your refills don’t last quite as long as they do with our standard K1 E Cig Batteries. Our independent testers reported that either they didn’t notice or only noticed a very small difference in how long they lasted which was outweighed by the benefits of the K2.
