Olight i17 USB-C Rechargeable Rotary Head Keychain Light To celebrate the 17th anniversary of its founding, Olight has created the Olight i17, a keychain flashlight featuring USB-C rechargeability and an ultra-compact form factor perfect for EDC. The light provides up to 180 lumens for maximum visibility when walking to your car or taking the dog out for a walk. A second output at 5 lumens is extremely useful for illuminating close-up tasks like unlocking the door, and this level boasts a 12-hour runtime to get you through any obstacle or task you're facing. The i17 has a built-in lithium-ion battery, saving you the trouble of constantly finding replacements. Thanks to USB-C connection, this power supply charges in just 90 minutes so you can stay on the move throughout your day without waiting for the i17 to charge up. The USB-C connection port is recessed to prevent contamination during daily use.
