Absolutely. These heated socks are specifically designed for cold outdoor environments and are ideal for skiing, mountaineering, hiking, cycling, or everyday winter warmth.

It is not recommended to wear them while sleeping for extended periods. Although the product features temperature control protection, the body's ability to sense temperature decreases during sleep, and prolonged high-temperature heating may cause low-temperature burns.

The battery must be removed before washing. The socks themselves are hand-washable (water temperature recommended not to exceed 30°C / 86°F). Do not vigorously rub the heating element areas. Allow them to air dry naturally after washing; do not use a dryer or spin-dry vigorously.

No. The heated socks must use their matching dedicated rechargeable batteries. Directly connecting a power bank may cause voltage instability, damage the heating elements, or pose a safety hazard.

Yes, but in accordance with aviation regulations, lithium batteries must be placed in carry-on luggage and are strictly prohibited in checked luggage. It is recommended to confirm the airline's specific restrictions on lithium battery capacity in advance (usually required to be under 100Wh).

This product features 4-level temperature control. You can switch between different temperature levels using the power button on the battery, allowing you to adjust at any time based on actual outdoor temperatures and personal comfort.

Usage time depends on the selected temperature level. Generally, lower settings (energy-saving warmth) last longer, while higher settings (rapid heating) consume battery faster. Please refer to the product manual for specific runtime details.

Remove and charge the battery promptly after each use. Avoid scratching the heating elements with sharp objects during washing. If not used for a long time, charge the battery to about 50% and store it in a cool, dry place.

Battery lifespan depends on usage frequency and maintenance. Under normal use, the rechargeable lithium battery can undergo hundreds of charge cycles. If you notice a significant drop in runtime, it is recommended to contact customer service to replace it with an original battery.

The product utilizes safe heating elements and multiple circuit protection designs, making it very safe when used according to the manual. However, do not disassemble the battery or heating components without authorization.

They must be worn on dry feet and used in conjunction with shoes. Do not use if you have wounds on your feet, poor blood circulation, or reduced sensitivity to heat.

1. Strictly prohibited to charge in a damp environment; 2. Strictly prohibited to use non-original batteries; 3. If you notice broken heating elements, bulging, or abnormal battery heating, stop using immediately.

The product typically covers standard men's and women's sizes (e.g., one-size-fits-all or S/M, L/XL). Since heated socks need to fit closely to ensure effective heat transfer, it is recommended to refer to the merchant's size chart before placing an order.

Do not pierce the socks with sharp objects (to avoid damaging the heating elements). Do not immerse the battery in water. If you feel overheated during use, immediately lower the setting or turn off the power.
