Picked up this 15 ft extension cable to move my Skylight further from the Yeti, and it does exactly what I needed. The 6 mm input and output match the ports on my Light-A-Life 350 and Alta 50 without any adapters, and the 18 gauge cord feels solid enough for regular use around camp. Fifteen feet gives me plenty of slack to hang a light where it is actually useful. Simple, no fuss, and it just works with the Goal Zero gear I already own.
