حزمة بطارية Vivitar GP-H4 1000MAH لـ Go Pro Hero 4

I've been using this battery pack for weekend hikes and it easily outlasts my entire day of filming, which is exactly what I needed. The compact size is perfect for slipping into a pocket without adding bulk to my gear.

Charged my Hero 4 three times over a long shoot weekend and it stayed surprisingly compact in my pocket the whole time. The 1000mAh capacity is exactly what I needed to stop swapping batteries every hour, and it fit my Hero 3+ too, which was a nice bonus.

This little battery pack doubled my Hero 4's recording time on a long hike, and it's impressively compact – barely adds any weight to the setup. Great for anyone needing extra runtime without the bulk.
