The ASP Triad USB adds a micro USB charge port, internal charge circuit and Lithium-Ion power cell while maintaining the premium features found in the Triad design. A foamed vinyl grip complements a matte black Type III hardcoat anodized aerospace aluminum body. The rear switch rotates through an intermittent, locked and 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 LED to Lumens: 550 (high), 15 (low) as measured against the ANSI FL1 Standard. The Triad USB comes with a retractable USB charging cable, wall charger and car charger, and indicator lights show the battery's charge status. Dual Fuel Technology of the Triad USB allows use of the CR123A primary cells. The batteries are unaffected by the Triad USB charge circuit.
