Boasting a battery capacity of 2600mAh there is no guessing as to why they call it the MVP.

Along with all that the MVP is variable voltage and adjusted from an easy to read LED screen. Battery life ranges from 2-3 days after being fully charged. Includes an iClear with swivel drip tip. Available in colors: black, silver, and blue.
