Power up and press ahead. Compatible with the COAST XP14R flashlight, the ZX710 ZITHION-X™ rechargeable lithium-ion battery sets you up to charge your battery inside or outside your light. The battery features a built-in USB-C port, a battery charge indicator—which flashes red during charge-up and shines solid green when fully charged—and overcharge/discharge protection circuits to make powering up as simple and safe as possible. Also outfitted with a USB-C out port, the ZX710 can be a portable power bank to charge your cell phone or any external device. COAST’s one-year warranty backs the battery against defects in materials and workmanship.
