BASEUS Universal AC Adapter 3-24V 3A 72W 14 Tips Polarity Converter

Universal 3–24 V adjustable adapter

This BASEUS AC/DC adapter delivers an adjustable output from 3 V to 24 V at up to 3 A and 72 W. Fourteen interchangeable DC tips cover barrel sizes from 2.5 mm to 6.5 mm plus Micro-USB, Type-C, terminal and alligator-clip connectors. A reverse-polarity converter is included for devices with centre-negative sockets. The unit accepts 100–240 V AC at 50/60 Hz for worldwide mains compatibility.

Practical limits of the adjustable output

The maximum continuous power is 72 W, so any device drawing more than 3 A at the selected voltage will trigger over-current protection. Automatic cut-offs also guard against over-voltage, over-temperature and short-circuit conditions. The 6 ft mains cable is rated for indoor use only. No battery-charging circuitry is present; the adapter simply supplies a regulated DC voltage.

Replaces fixed-voltage bricks up to 72 W

One unit substitutes for multiple single-voltage chargers rated between 3 V and 24 V, reducing cable clutter for routers, LED strips, 3D printers, DVR/NVR boxes and similar small electronics. The upgrade is worthwhile when you regularly power several devices with different barrel sizes or polarity requirements. It is not suitable for laptops or appliances that exceed the 72 W ceiling or demand a proprietary communication protocol.
