One of these with an Aspire K-1 tank was what I started on some time ago. The 54 gram iStick mini is the lightest mini mod I have come across and most other minis weigh 95 grams or more. The iStick mini with an Aspire K-2 tank only weighs 84 grams. It can drive a 1.6 ohm coil at about 7 watts for several hours on a charge. That is a half day of satisfying puffs. This mod is highly recommended.
