Selecting a Therm-ic battery boot heater.

First, select a Powerpack heat system!
A Powerpack is simply the batteries that power the heat. You have 3 options.

#1- Powerpack alone- (the left column) If you have a pre-installed heating element in your boots, all you need is a Powerpack.
#2- Powerpack with heating element- (the middle column) If you do not have pre-installed heating elements, this is the least expensive way to heat your boots. Works great for close fitting boots and if you have custom insoles.
#3- Powerpack with Thermicsoles- (the right column)  If you do not have pre-installed heating elements, this is the easiest to install! The Thermicsoles offer extra support for comfort and have the heating elements built into the insoles at the toes. (Do not order this system if you have custom insoles.)

Next, select a Powerpack battery type.
You have 5 battery options.

#1- Basix- Uses AA batteries which allows this Powerpack to be used anywhere in the world.
#2- Max- Uses rechargeable 1600 nickel metal hydride batteries. Includes a charger for use in the North America only.
#3- SuperMax- Uses rechargeable 1900 nickel metal hydride batteries. Includes a global charger for use in the USA or Europe.
#4- Liion- Uses small light weight rechargeable Lithium-ion batteries. Includes a global charger for use in the USA or Europe.
#5- Liion with remote- Uses small light weight rechargeable Lithium-ion batteries that operates by a remote control. Includes a global charger for use in the USA and Europe.
