Built for the moments when power matters most.

Most power banks are designed for coffee shops, airports, and office desks.

The Dark Energy Poseidon Pro is built for everything else.

Waterproof, dustproof, drop-resistant, and engineered to perform in harsh environments, the Poseidon Pro is a rugged 10,000mAh power bank designed for travel, outdoor adventures, emergency preparedness, and everyday carry. Whether you’re navigating a storm, spending time off-grid, dealing with a power outage, or simply need dependable backup power, the Poseidon Pro is built to keep your essential devices running when other batteries fail.

Despite its rugged construction, the Poseidon Pro remains remarkably compact—about the size of a smartphone—making it easy to carry in a backpack, travel bag, glove box, emergency kit, or everyday carry setup. The 10,000mAh battery provides approximately 2–3 full charges for most smartphones and can power everything from phones and GPS devices to headlamps, radios, cameras, and other USB-powered gear.

Designed to withstand real-world abuse, the Poseidon Pro features an IP68 waterproof and dustproof rating, allowing it to be fully submerged in up to 6 feet of water for 45 minutes. Its reinforced housing exceeds MIL-STD-810G standards for drop, crush, shock, and environmental resistance, while built-in surge protection and voltage regulation help keep your devices safe while charging.

Dual USB-C fast-charging outputs and a USB-A port provide flexible charging options for modern and legacy devices. Additional features like Low Power Mode for sensitive electronics and a built-in 1-Hour Timer help maximize efficiency and battery life when every charge counts.

Pair it with the Dark Energy Spectre 18W Solar Panel (sold separately) for a dependable off-grid power system capable of keeping your essential gear charged wherever the journey takes you.
