20 V 45 W barrel adapter

This 20 volt 45 watt AC adapter uses a barrel connector to power compatible devices. It is intended for users who need a replacement mains supply for equipment rated at 20 V DC.

Continuous 1.5 A output under load

The unit delivers a steady 1.5 amp current at 20 volts when operated from a 60 hertz mains source. Class 2 construction limits the available power so the adapter runs within its thermal design during extended use.

Barrel plug tip excludes two-prong devices

The round barrel tip fits only equipment with a matching jack; it will not connect to two-prong or other connector types. Buyers who need a different plug format must choose another adapter.

Questions about this item

Does the 45 W adapter run hot or make noise when powering a light continuously?

The unit is a sealed Class 2 supply rated for 45 W at 20 V and 1.5 A; it has no fan and operates silently, with only normal warmth during extended use.

What must I already have for this 20 V barrel adapter to work with my Xing Yuan light?

You need a mains outlet supplying 100-240 V at 60 Hz and the light must accept a barrel connector with centre-positive polarity.

Will this 20 V 1.5 A supply safely replace the original XY-2001500-U brick on an older tank light?

Yes, it matches the original 20 Vdc 1500 mA output and 45 W maximum, so it will power the older light without overloading it.
