Poseidon Pro Power Bank

The power bank you forget about until the day you really need it.

Most power banks are made for a desk drawer. The Poseidon Pro by Dark Energy is made for a truck bed, a tackle box, or the bottom of a go-bag. It's IP68 waterproof and dustproof, wrapped in Dark Energy's Armor Flex shell, and built to exceed MIL-STD-810G military durability standards. And when it has been sitting unused for months, it still has power left.

Dark Energy says it keeps 95% of its charge after 18 months in storage. So the battery you packed last spring is still ready for this year's outage, trailhead, or roadside breakdown.

Why it earns its place

• Survives getting wet: IP68 rated. It can be submerged up to 2 meters (about 6 ft) for 45 minutes, and rain, mud, and dust aren't a problem.
• Handles rough treatment: The Armor Flex polymer shell is designed to take drops, crushing, and rough handling that would crack an ordinary power bank.
• Keeps its charge: Dark Energy claims 3+ years of charge retention, so it's ready for your emergency kit.
• Charges your phone 2–3 times: 10,000 mAh, with three ports so you can charge more than one device.
• Works in the cold: Rated to operate from -20°F to 140°F.
• OK to fly with: At 38 Wh, it's well under the 100 Wh airline carry-on limit.
