The NITECORE UGP5 is a powerful dual slot battery charger designed exclusively for GoPro Hero5 batteries. Utilizing Active Current Distribution (ACD) technology the UGP5 intelligently distributes power to boost recharge speeds up to 750mA per slot. This allows batteries to fully charge in as fast as 1.5 hours, which means more time shooting and less time waiting to record. Built-in battery protection and an easy-to-read LCD display alerts users of any potential issues with batteries and will even automatically terminate charging to ensure your batteries are always protected. Designed to be a lightweight and highly portable the UGP5 begs you take it everywhere you go - no need to worry about coming home to recharge! The UGP5 can recharge batteries using various mobile power sources such as solar panels, power banks, USB adapters, and more. Which gives you the freedom to recharge anywhere your adventure takes you!
