The Geekvape M100 is the second generation of the Aegis Mini. Just like the Aegis Mini, this is a highly durable and water-resistant device. However, it now goes all the way up to 100 watts and they have switched over to a USB Type-C charging port for faster charging. Additionally, the have added a super convenient lock switch on the side of the mod, so you don’t have to turn the device off to safely store it in your pocket or purse.
