The Stamp Thermoelectric Generator

Stamp is a device that keeps your mobile gadgets charged on the go. Everything from smart phones, GPS devices, two-way radios, and any other device with USB charging can be used with Stamp.

It allows you to keep your mission critical gadgets charged off the grid, using only heat. It stores the energy converted from heat into electricy in on-board batteries to be used whenever you need it. It has no moving parts, is rugged, and outputs through a standard USB type-A jack. This lets you plug in your own USB cord, preventing the need for adapters.

How to use it:

Stamp can be charged two ways:

Pre-charge it from a wall outlet before you leave the house so that you start with a full backup battery.
Use heat to recharge Stamp on the go using any heat source you can find, such as camp fires, stoves, hot rocks, idling engines, and more.

How does Stamp work?

Stamp uses advanced thermoelectric materials paired with a unique closed circuit cooling system to charge your devices. This means that it turns heat into electricity with no moving parts or systems to maintain. You don't have to feed it fuel or fiddle with the cooling system.

How big is it?

The current prototype is 3" wide at it's biggest point and about 5" tall. It's lightweight, handheld, waterproof, and shock resistant so you can trust it on your toughest excursions.

Who is Stamp for?

Stamp is great for outdoorsmen, emergency first responders, bug out bags, natural disaster preparedness, or any other situation where you need to keep your mission critical gadgets charged.
