[Multiple Protections]: 9 volt dc power supply uses flame retardant materials, which is safer, and has built-in short circuit protection, electrostatic protection, overheating protection, overvoltage protection, overcurrent protection and other multiple protections
[Safe and Reliable]: The actual output voltage fluctuation does not exceed 0.5v, and the stable voltage makes your device more durable. If the charger works at a high load of more than 80% for a long time, it will get hot and shorten the service life. Choose this 9v 3a power supply to charge your 2A 1A 0.5A and other devices under light load, which is safer and has a longer service life
