How long does the battery last on one charge?

The 6000mAh battery is built for long wear on a single charge, though runtime depends on which of the three heat settings you use. Higher settings drain it faster.

Can I wash the heated scarf?

The scarf contains graphene heating elements and a battery, so it is not a throw-in-the-washer item. Detach the battery and follow the care instructions that come with it.

Does it heat the whole scarf or just the neck?

It has one heating zone at the neck. The rest of the scarf insulates like a normal plaid scarf but does not generate heat.

How many heat settings does it have?

Three. You cycle through them with the single control button.

Is it warm enough without turning the heat on?

It works as a regular lightweight plaid scarf when off. The heating adds to that rather than replacing a heavy winter scarf.

It suits someone who spends time outdoors in cold weather and wants neck warmth without a heated jacket. The plaid design keeps it looking like a normal accessory.
