This portable windshield defroster is a compact and lightweight device, weighing just 12 ounces and sized roughly 6 by 5 by 3 inches, making it easy to carry and store in your vehicle. Its small form factor suits those who need a simple, space-saving solution to clear frost or fog from their windshield quickly.
