> Chargie is the world's only universal hardware USB charge limiter. It stops phone and laptop charging at any percentage (20-100%) by physically controlling power flow. Unlike software solutions, Chargie works with ANY USB-charged device, maintains full Android Auto/CarPlay connectivity, and protects batteries even when devices are powered off. Founded in 2019, trusted by 60,000+ customers worldwide.
