"I bought the reserve battery pack. I don't come out of the woods for lunch and the extra battery keeps my electric socks going all day."

Extra-Long Wire Option for Trout Fishermen

Thunderbolt offers a extended wire option. This allows the placement of the battery/ controller in a pocket of your chest waders.*

*This is an option added to a sock order only since the sock is specially built with a longer cable.

Battery Packs

Lithium Ion Battery Pack

A second battery pack doubles the time you can spend in the field between recharges and is recommended for all-day use in cold weather. An extra advantage is that one battery pack can be recharging while the other is in use. Battery cells don't exhibit "memory" and don't have to be completely discharged before recharging. The accessory pack is identical to the original and easily slips into the waist-mounted pouch. For convenience in carrying the second pack before it is needed, order the extra pouch below. One pouch can be clipped to each side of the waist.

(Requires #1542 Rapid Charger listed below)

Liner Socks

We recommend a liner socks be worn inside the thunderbolt electric socks. This allows the user to wash the liner socks frequently and hand-wash the electric socks less often.

Any thin sock may be used as a liner, but we offer a high-quality liner sock especially designed to wick away perspiration. Our recommended liner socks feature:

1. X-Static silver coated nylon to help eliminate foot odor naturally.

2. Silver provides natural thermal conductivity to even out foot temperature.

3. Smooth, flat toe seam for maximum comfort.
