Hahnel UniPal Mini II Charger

Small enough to toss in my camera bag without noticing, but it charges my batteries reliably from a power bank on long hikes. The compact size really does make it easy to keep with me everywhere.

The ability to charge it from a USB power bank is a game-changer for camping trips. I've used it twice now and it tops off my camera battery without any fuss. Perfect size for my bag.

I was surprised how well this compact charger works with my portable power bank when I'm out hiking. It's tiny enough to slip into any bag pocket without adding bulk, and it charged my camera battery from dead to full in a couple hours.
