The Poseidon Nano is a compact and powerful portable charger, designed for on-the-go use. It's notably small, about 40% smaller than its counterpart, the Poseidon Pro, making it easily fit in a pocket or purse. Despite its size, it has a high energy density with a 3,000 mAh power capacity, providing 5-8 hours of power for smartphones, and more for other devices. It's versatile with both USB-C and MagSafe compatible charging options. Durability is a key feature; it's water-resistant (IP67), has a super resilient outer shell, and maintains charge for over two years.
