CampMate-3 is compact enough to toss in a bag or carry on the go. The built-in 9000mAh battery can also charge your smartphone so that you never run out of power on the go. The super bright LED light is powerful enough to use in the darkest environments or use it as a powerful torch or a flashing SOS alert device. You can switch between warm and daylight modes as well as change brightness levels or use the SOS mode in case of emergencies.
