The INOVA X3R - USB Rechargeable LED Flashlight is built to sustain years of tough recreational or professional use. Its precision-machined, solid aluminum body has a high-grade anodized finish, is impact resistant, shock proof, crush-proof, and water resistant. The Inova X3r USB Rechargeable Flashlight has a patented optical system which is protected by a stainless steel head, features a high-powered, 35,000 hour LED, and a machined aluminum reflector for optimal thermal management and beam projection. A patented 3-position end-cap switch conveniently activates constant and momentary high and low power modes, as well as lock out mode. The Inova X3r USB Rechargeable Flashlight includes a USB charging cable that is compatible with any standard 1A 5v USB output, including AC adaptors, DC adaptors, computers, and solar panels. Its mini USB port and charge indicator are protected under a water-resistant seal - simply twist the head to expose, and twist back once the flashlight is charged to re-seal.
