Multiple layers of intelligent protection—overvoltage, overcurrent, short-circuit detection, over-temperature protection, and over-charging prevention—keep your devices safe, whether you’re charging Bluetooth headphones or your daily driver smartphone. Every RA-USB meets CE, FCC, and RoHS certifications for peace of mind.
