The Off-Road is the perfect companion for your outdoor adventures. Its solar panel allows you to re-charge using direct sunlight and the IP65 certification makes it dust-proof and water-resistant. Its rubberized finish, metal carabiner and built-in flashlight also make it an ideal accessory for hiking and camping. Let the power bank soak up the sun outdoors to optimize solar recharge. To recharge the Off-Road a little quicker, use the micro-USB/USB cable and plug into a power source. . SPECTECH-POWER PRODUCTS HAVE A ONE YEAR WARRANTY ON ELECTRONIC PARTS FROM DATE OF PURCHASE.
