Your phone dies. Your GPS goes dark. Your communication cuts out. Out there, when it matters most, you need power that won't fail you.
Order Now — $99.99It was 3 AM on a mountainside in Colorado. The temperature had dropped to 12 degrees. My hunting partner's phone — his GPS, his lifeline, his only way to call for help if something went wrong — was dead. His charger? It had failed hours earlier. The battery had drained to nothing in the cold, just like every other charger he'd ever owned.
I pulled out my Poseidon Pro.
Thirty minutes later, his phone was at 80% charge. We finished the hunt. We got home safe. And he ordered his own Poseidon Pro that night.
That's the difference between a charger and a tool that saves your life.
Here's what you already know: they fail exactly when you need them most.
You buy a charger. It works great for a few months. Then one day — maybe it's dropped in water, maybe it's been exposed to extreme cold, maybe it just got banged around in your pack — it stops working. Or worse, it slowly loses its ability to hold a charge. By year two, it's practically useless.
The problem isn't that these chargers are cheap. It's that they're built for a comfortable life in a climate-controlled home. They're not built for the real world.
You're not in the 80% of people who use chargers in perfect conditions. You need something different.
The only portable charger engineered for the harshest conditions on Earth.
This isn't a charger that claims to be tough. This is a charger that has been tested beyond military standards. It's been dropped from 75+ feet onto rock. It's survived a shotgun blast. It's withstood 1,500 pounds of crushing force. It's been submerged in water for 45 minutes and came out working perfectly.
And it's been proven in the field by U.S. Special Forces, backcountry hunters, mountaineers, and first responders who literally depend on it to stay alive.
Built with Armor Flex Technology — a steel-like polymer that absorbs impact and shrugs off abuse. Exceeds MIL-STD-810G military standards. Drop it 75+ feet onto rock. It survives.
Fully submersible in 6 feet of water for 45 minutes. Not "splash proof." Not "water resistant." Completely waterproof. The only charger with this capability.
Power Pulse technology delivers charging speeds 2.5x faster than ordinary chargers. Full phone charge in 30 minutes. In an emergency, that's the difference between being connected and cut off.
Holds its charge for 3+ years. Pack it away in your truck, cabin, or emergency kit. When you need it — whether that's 6 months or 3 years from now — it will be ready.
2 USB-C outputs (fast charge) + 1 USB-A output. Charge your phone, GPS, and headlamp simultaneously. Built-in surge protection and voltage regulation for safe charging every time.
We stand behind the Poseidon Pro because we know it's built to last. A full 5-year Dark Energy Warranty covers defects in materials and workmanship. If anything goes wrong — we'll make it right.

"The Poseidon Pro is a mandatory part of my summer and winter kits. On a Search and Rescue team here in the Sierra Nevada Mountains, it's been a critical piece in my pack to help sustain overnight missions, keeping my phone and GPS apps charged. Incredible product that I've tested in cold, wet temps multiple times — never fails."
"I am in Search and Rescue at the edge of the Cascades and the High Desert. I carry the Poseidon in my 24-hour pack on every training and every mission. Do not have to worry about winter temps or water. Don't go out without it."
"I use this while stand hunting whetail in New Jersey. Hours of down time, I plug my cell phone in and watch movies all day. Without it my phone would be dead within a few hours, especially during the frigid NJ winters. This is a must have for any hunter. You won't regret the investment."
"As a former Navy SEAL, I believe this is a very dependable and reliable device that can be trusted. I've been all over the world and there are numerous circumstances — many unforeseen — that require a recharging apparatus that will work when it needs to work. I approve of this device."
When you order the Poseidon Pro, you're not just buying a charger. You're buying:
The knowledge that your power source won't fail you when it matters most — in the backcountry, on the fireline, or in any emergency.
A tool that's been proven by U.S. Special Forces, backcountry hunters, and first responders who literally depend on it to stay alive.
A charger that will outlast every other piece of gear you own — built to exceed MIL-STD-810G military standards.
Reinforced USB-C cable included — everything you need, nothing you don't. No hidden costs.
A full five-year Dark Energy Warranty. We stand behind the Poseidon Pro completely because we know it's built to last.
A charger that holds its charge for 3+ years and will work reliably for a decade or more — the last power bank you'll ever need to buy.
The Poseidon Pro provides 2–3 full phone charges depending on your device. Most modern smartphones will get 2–3 complete charges from a single Poseidon Pro charge.
Using a USB-C charger (5V/3A, 9V/2A, or 12V/1.5A), it takes approximately 4–6 hours to fully charge. We recommend charging it the night before your trip.
Yes. The Poseidon Pro has an IP68 rating, which means it can be fully submerged in 6 feet of water for 45 minutes and emerge completely functional. This is the highest waterproofing rating available for portable chargers.
Cheaper chargers are generally not waterproof, shockproof, or built for extreme use. The Poseidon Pro is engineered to survive in the harshest conditions on Earth — it's the difference between a charger designed for your desk and a charger designed for real life.
The Poseidon Pro holds its charge for 3+ years. You can pack it away and forget about it, and when you need it years later, it will be ready to go.
Yes. The Poseidon Pro operates reliably in temperatures from -15°F to 100°F+. It's engineered for extreme conditions — heat, cold, moisture, and elevation.
The Poseidon Pro and a 3-foot reinforced USB-C cable. Everything you need — nothing you don't.
The Poseidon Pro comes with a full 5-year Dark Energy Warranty covering defects in materials and workmanship. If anything goes wrong, we'll make it right — no questions asked.
Yes. The Poseidon Pro has 2 USB-C ports and 1 USB-A port, allowing you to charge up to 3 devices simultaneously. It also features a Low Power Mode for safely charging sensitive electronics like Bluetooth earbuds or smartwatches.
The Poseidon Pro is available in Hi-Vis Orange, Desert, Green, and Black — all in stock and ready to ship with free shipping on every order.
The next time you venture into the wild — whether it's a week-long hunt, a multi-day backpacking trip, or just an unpredictable day in the field — you want to know your charger won't fail you. The Poseidon Pro is ready. The question is: are you?
