We strongly recommend that all heated garments be cleaned at the end of the season to remove dirt and body salts before extended storage.

Prepare the PowerPacks should be prior to storage by:
• Fully chargen the PowerPacks.
• Attach your heated garments, turn them on and run the heat until you reach approximately 80% battery charge.
• Repeat the operation at least every 6th month.

Keep the PowerPacks together with the charger adapter in a warm and dry location, avoiding excessive humidity conditions. The last thing you do after a week of usage or when spring comes, make sure the socks are washed clean and that there is no unnecessary dirt or salt crystals left as they can damage the product over time.
