Tips 1. Please use 5V charger (Smart Phone, External Battery, Cigar jack etc) 2. When you connect Starroll to charger, it automatically heats up and then after 2~3 minutes, it turns off automatically (LED Lamp out) 3. When you use lower than 1.8v charger, it will take longer to ramp up 4. If you try to use it continuously, please wait around 3 minutes. For safety issues, the sensor works on when it goes down to certain temperature.
