Power that keeps pace

Morning frost on the tailgate, river spray on your boots, a signal when the map turns blank—the Poseidon XL holds steady so the day can stretch farther.

Out there, still on

Poseidon XL Power Bank

Built for the blank spots

Dead batteries end good plans—cold nights, long drives, and remote trailheads don’t care about a phone’s last bar. Poseidon XL brings 100 W USB‑C input and output, pushing real power to laptops and even a Starlink Mini. It comes with a matching 100 W USB‑C cable, so you’re not hunting for the right lead when the light fades.

Momentum, uninterrupted

When the workbench is a truck bed or a riverbank, dependable energy becomes part of the kit. Poseidon XL means cameras upload, maps stay open, and calls go through when plans change. It’s the difference between turning back early and staying with the moment.

For the ones who keep going

Travelers, field creatives, and off‑grid crews who need laptop‑level power away from an outlet.

In the wild and at home

Stow it in a pack or glove box to fast‑charge a laptop via USB‑C while keeping a phone and satellite gear ready during long days off the grid.
