cordless electric blanket

Options include USB-powered models that run from a 5V/2A USB supply or power bank, and larger bed comforters that use a wireless LCD controller/remote for heat adjustment.

Care varies by product: some wearable shawls recommend hand washing or line drying; several items offer machine-washable blankets or removable, machine-washable covers; one comforter specifies washing only the removable cover while the inner heated insert should be spot-cleaned.

Some larger comforters are ETL certified and list overheat protection. Several products also mention intelligent NTC/PTC heating wires or sensors that monitor and regulate temperature.

Controls range from simple press switches or dual-switch controls on USB wearable blankets to wireless LCD remotes on larger comforters. Timers (commonly 1–10 hours) and multi-level heat settings are frequently available.

Settings vary by product: some wearable USB shawls offer three heat levels around 40–60°C (104–140°F) or specific steps such as about 113°F, 122°F, and 131°F. Larger bed comforters commonly provide six heat settings with a maximum near 45°C (about 113°F).

Sizes range from wearable shawls (about 59 × 31 in and a medium at 53.15 × 43.31 in) up to bed-sized comforters such as 90 × 90 in and 104 × 90 in (also listed as 90 × 104 in).

They plug into any 5V/2A USB supply or power bank and typically include a pocket for the power bank. Designs (zippers, wearable shapes) allow free arm movement, they fold for easy transport, and listed weights are about 1.54–1.87 pounds.

Wash only the removable ruffle/duvet cover (machine wash; some listings specify cold wash and tumble dry low). The inner heated comforter is intended to remain in place and should be spot-cleaned as needed rather than washed regularly.
