Gemini 4000mAh 2 Cell Battery
Gemini's new battery packs are loaded with capacity and functionality.
Built with 21700 cells instead of 18650 cells they are slightly larger and heavier but come with a higher power to weight ratio.
On top of that they have some neat tricks up there sleeves.
They have the standard 5.5x2.1mm round connector used to power the light but also have a USB-C plug to power your phone, Garmin, GoPro or any other USB powered device. You can use both at the same time.
There is a fuel gauge on the side of the pack that with the push of a button tells you how much power you have left.
They can be charged using either port using a 5V USB charger or 8.4V wall charger.
