AC/DC 20V 4.25A Desktop Power Supply Adapter
AC/DC 20V 4.25A Desktop Power Supply Adapter Description:
Desktop power
adapter is a kind of external power supply, to provide transformed voltage for
electronic products we usually use, such as laptop, router, electric massager,
table lamp etc. Qualified power adapter requires good quality electronic
components, so that it`s life span and work efficiency could be guaranteed.
Inferior electronic components are used in the power adapter, will reduce the
working times of products, and it`s not safe for other products.
JYH power
adapter always chose qualified material to manufacture power adapters, because
we believe quality is the life source of enterprise.
20V4.25A ,85W rated output, 100Vac-240Vac input, 1.2m DC cord, IEC320-C6C8C14
