DEVOA 2022-23 Autumn Winter Collection.

◆◆About scarves

The scarf is made in "river tailoring" by stitching together two pieces of fabric made of 100% cashmere.
All of this river-stitched fabric is originally stitched once and an electric heating sheet is sewn on one side, then the sheet is sandwiched between the fabric and the edges of the fabric are all hand river-stitched.

◆About Electric Heating Sheets

The internal electric heating sheet is a newly developed sheet of thin aluminium bonded in a three-layer structure by Swiss high-performance materials manufacturer Schoeller and crimped to prevent electric leakage.
The electric heating sheet is included only in the back of the neck (about 8 cm long and 38 cm wide), and when worn, the stitched part of the electric heating sheet is on the inside.
The internal electric heating sheet has a cord with a USB tip that works with the included battery, and the switch changes color depending on the temperature setting.
The cord is long enough to hold a battery in the front pocket of your pants, not to mention in the pockets of your jacket and coat.
The temperature can be adjusted in four levels of maximum power from red to purple, green and white, and the output status during use can be seen in these colors.
The following are guidelines for each color.

Red (very hot)

Purple (hot)
Green (medium)
White (low temperature)

◆About the battery

The battery has a capacity of 6800 mAh and runs for about 6 hours continuously from full charge at maximum power (red) and about 8 hours continuously on medium (green).
The battery is charged via USB, so if you're working on a computer, you can use it directly from the computer without going through the battery.
Also, you don't have to worry about the difference in voltage from country to country, so you can use it all over the world.
This battery operates at USB output port output voltage: 5V output current: 2A or higher.
