The Sierra Madre Secret to Instant Heat!

A heated jacket is just a jacket if you can't feel the heat!

That's why we invested the time, brainpower, and money to create a power pack that was truly capable of the job. Check out the video below to see how we did: 

The source of this instant heat is our proprietary power pack and new heat panel technology.

These aren’t your run-of-the-mill, 5V “trickle-bricks” either. Our PowerPacks are purpose-built, USBC-PD equipped power banks that are capable of pumping out up to 60 cold-killing watts. 

This translates to warmth you can actually feel for up to 12 hours per charge!


  • Hi, I tried to enlarge the pop up box to check my email spelling while trying to get added to the notification list for the big launch & the box disappeared permanently.

    How can I get added to your list to get notified about the launch time?
    Thank you!
