Dark Energy Poseidon XL Power Bank

Built to thrive where others quit, the Poseidon XL delivers uncompromising performance in the world’s harshest environments. With a 100 W USB-C input and output, it powers everything. Whether you’re deep in the backcountry or off the grid entirely, this is the power source you trust.

The Poseidon XL delivers 100 watts of output in a compact, TSA-compliant design—strong enough to power laptops, cameras, drones, and even Starlink Mini. It’s the new standard for field-ready energy.

In the backcountry or the battlefield, power isn’t optional—it’s survival. The Poseidon XL was engineered for extremes: fully submersible, drop-proof, and built to operate from –10°F to 120°F without losing charge. 

Dark Energy builds power for the extremes—for people who don’t turn back when things get hard. The Poseidon XL represents everything we stand for: relentless performance, uncompromising strength, and the freedom to go further than ever before.
