UNIFIVE – AC adapters & switching power supplies.

"AC Adapter Day, April 10 ".

We, UNIFIVE, applied on behalf of the switching power supply industry to 

Japan Anniversary Association to enact AC Adapter Day in Japan.

AC adapters are indispensable to each person’s daily life as they connect the electric appliances around you. We supply and deliver safe and reliable

AC adapters from our own manufacturing plant in China to major electronics companies all over the world. We can provide the best power source solution for you.   

The goal of AC Adapter Day is to let more people understand how to use AC adapters properly, how to maintain them, the various types of switching AC adapters, etc. We believe this knowledge will spread further in the future.

From now, UNIFIVE, will continue to provide useful news for everybody through its website, e-mail, etc.
