The Keychain EGO battery is a miniture model of our EGO battery but with a keychain twist. Literally.... a cap that attaches to a keychain and twists off. This little device packs a lot of punch with 350 mAH and equipped with a 3 click on/off switch. Compatible with our EGO charger and all of our flavored cartridges, this accessory is a perfect addition to your Premium collection.
