Product Information "Therm-ic S-Pack 4000B Battery for Bluetooth Heated Socks (2-Pack)"
The Therm-ic S-Pack 4000B is the battery pair for Therm-ic heated socks with S.E.T. or Fusion technology: up to 23 hours of warmth on Level 1, three heat settings, Bluetooth control via the Heat Control app, and USB-C charging. The socks are not included; please order them separately.
Therm-ic S-Pack 4000B: Battery for heated socks with Bluetooth
The two batteries attach to the waistband of the heated sock with snap buttons, securing them firmly above the ski boot. You can select the heat setting on the battery or via the app while on the lift, without having to roll up your pants. The housing is splash- and dust-proof, and the included USB-C charger charges both batteries simultaneously. On level 1, the S-Pack 4000B lasts up to 23 hours; on level 2, up to 10 hours; and on level 3, up to 7 hours.

Intended Use
Skiing, ski touring, winter hiking, hunting, and anyone who, when their feet get cold, would rather have warmth for a whole day than just two hours.
Which socks are compatible with the S-Pack 4000B?
All Therm-ic heated socks with an S.E.T. connection, such as the Ultra Warm Performance S.E.T., Ski Heat Race S.E.T., and the Powersocks Heat Fusion. The snap buttons are the same on all models.
What’s the difference between this and the S-Pack 1400B?
More capacity. The 1400B lasts about 14 hours on level 1, the 3000B 18 hours, and the 4000B 23 hours. At level 3, that makes the difference between half a day and a full day of skiing.
Do I need the app?
No, you can also switch between the three levels directly on the battery. The app is handy because you can change the level on your phone even while wearing gloves.
How long does charging take?
Both batteries will definitely be fully charged overnight. It’s best to plug them into the USB-C charger after every day of skiing—lithium batteries don’t like being deeply discharged.
