Full copper output wire and sufficient material & high transforming rate. Using a new large-capacity large magnetic ring material, the performance is very stable. Heavy-duty protections, including Over Voltage Protection, Under Voltage Protection, Over Current Protection, Over Power Protection, and Short Circuit Protection. The efficiency is as high as 96%, which can reduce electricity bills. More energy saving! More environmentally friendly! The output does not fluctuate with the input voltage, so you can obtain a highly stable output voltage, really protect the computer.
