Innokin iTaste MVP is variable voltage box style VV mod featuring long lasting 2600 mAh battery, outstanding build-quality and excellent vaping performance. The iTaste MVP lets you adjust voltages from 3.3 volts to 5 volts, comes with one of the most powerful batteries to be featured on a device lithium-ion polymer 2600 mAh and works like a power bank, so it will charge any USB or micro USB device as well as an iphone or ipad. Together with the power, the iTaste MVP uses a pass-through charging system, which means you can charge and vape at the same time. MVP stands for "mobile variable power". In my opinion, the iTaste MVP is also the "most valuable player" in all Innokin products. there is no better box mod below 100 dollars, the iTaste MVP is definitely 'vaping out the competition'.
