The Triad® USB adds a micro USB charge port, internal charge circuit and Lithium-Ion power cell to the ASP signature design. Premium Triad features remain. A foamed vinyl grip complements a matte black Type III hardcoat anodized aerospace aluminum body. The four cut switch rotates to an Intermittent · Locked · Constant position. A replaceable belt clip may be attached lens up or lens down. All connectors and springs on the Triad USB are gold plated. The electronic circuit board drives a Cree XPG2 R5 LED to 300 lumens as measured against the ANSI FL-1 Standard. Loosening the head of the Triad reveals the micro USB charge port. Attach the retractable charging cable to the supplied car charger, wall charger or to a computer USB port. Even a micro USB cell phone charger can be used to recharge the Triad USB. The battery indicator of the Triad blinks red when charging. It turns solid green when fully charged. The wall charger, car charger and retractable charge cord are encased in a zippered ballistic carrier. The car charger and wall charger have a blue LED indicator to confirm that the power source is active.
