Care & Usage

Garment Care:

We recommend spot cleaning only for the safety of all ActionHeat items. Many of the ActionHeat items are machine washable if needed. These items include jackets, vests, base layers, hats, and balaclavas. Please read all the product manuals and instructions before washing.

Note: NEVER wash your batteries.

Note: We do not recommend to machine wash any of the heated gloves. 

Note: You can machine wash the ActionHeat socks in the provided mesh wash bag. 

ActionHeat Machine Washing instructions:

  1. Before washing, place all wires in pockets and fasten all zippers
  2. Wash separately from all other pieces of clothing
  3. Use mild detergent only. Do not use fabric softeners
  4. Machine wash with cold water on gentle cycle
  5. DO NOT put in the dryer, iron, or dry clean. Lay flat to dry


1. Be certain to use your power pack with an ActionHeat product with an Amp rating less than the maximum capacity output rating for the power pack. For instance, if each of the power packs has a maximum capacity output rating of (2) two Amps then they should not be used with heated products that draw more than (2) two Amps. Please check your products Amp draw before connecting the batteries to the power packs. Failure to do so can overheat the battery causing damage.

2. The recommended power setting of 50% is sufficient for temperatures between 50-64F. For temperatures below 50F, you will want to use the 75% or 100% settings. It is not recommended to use the 100% power setting for a long time as it may cause overheating and/or bodily discomfort.

Storage & Warnings:

1. It is important to maintain at least 25% of your battery power when not in use. Failure to do so will result in performance problems and reduced battery life.

2. Disconnect the power bank from the garment when not in use because even when it is turned off, the garment will continue to slowly drain power from the power bank.

3. Our power bank is similar to a typical

Good backup batteries
November 14, 2019
I have used the original heated socks batteries once and they performed well. I got these as a backup. I expect them to work just as well. ****Note*** the batteries pictured above were sent to me first in error as they are not the ones that work or come with the ActionHeat 3.7V Rechargeable Battery Heated Socks - Wool. The original batteries are flat, rectangular, black in color and fit in the calf pocket of the sock. The company exchanged the wrong batterries at no cost. Make sure you call and order them from an agent as the wrong batteries were sent even after I specified the type of battery that I needed in the comment section of the online order.
Proswork well, fit well
ConsWould like to have remote way to adjust the temperature as it is a little difficult to adjust the socks' heating level once you get them on under your pants, chaps, etc.
