Power that never weighs you down.
A powerbank is only useful if you actually want to carry it. That’s why we stripped away the bulk and focused on pure density. The Koltrast Powerbank delivers 10,000 mAh in a format that slides into any pocket, whether you’re heading up a mountain or sitting on a train. It’s your insurance policy in a digital world.
Maximum performance. Minimal size.

Weighing just 190g, you’ll barely notice it's there. It is specifically optimized to fit the battery pocket of our heated gear without feeling bulky, while remaining small enough to fit in your jeans pocket during daily commutes.
Power for the Long Haul
10,000 mAh provides enough energy to power our heated vest for up to 8 hours, or provide roughly 2–2.5 full charges for a modern smartphone. Perfect for long days away from a power outlet.
