This is an awesome new case from Innokin! Originally sold alongside the SVD 2.0, you can now buy this case as a standalone item. This is a semi-rigid zipper case with multiple mesh pockets and elastic straps for all your vape gear. Built in to the case is a battery tester! Just connect the magnets to either end of any 3.7V battery, and the LED lights will display your remaining battery charge! If all 5 lights are illuminated, then your battery is fully charged.
