LED Fuel Gauge - The innovative LED battery fuel gauge/charging indicator is cleverly integrated into the power button of both the Flea and Super Flea lights. Now you no longer have to guess how much battery life is left, just follow the simple color code. Green = 100% - 75%; Orange = 75% - 25%; Red = 25% - 0%
Patented Magnetic Power Adjustment - Found on the Flea and Scorch lights, electrical current is passed through the magnets, allowing for a compact and watertight connection. In the case of the Flea lights, it allows for mounting in both horizontal and vertical USB ports.
