Universal 12 V Power Adapter

This BASEUS AC adapter delivers 12 W at 12 V and 1 A for a wide range of low-power devices. It accepts 100–240 V mains input at 50/60 Hz and includes a 150 cm power cord with a US plug. Ten interchangeable DC tips cover common barrel sizes from 2.5 × 0.7 mm up to 6.3 × 3.0 mm plus an LED terminal connector. Centre-positive polarity is standard across all tips.

Replaces Lost or Damaged 12 V 1 A Units

The adapter substitutes any 12 V supply rated at or below 1000 mA such as those for LED strip lights, routers, modems, network switches, IP cameras, TV boxes, small USB hubs, mini fans, portable radios, GPS units, DVRs, humidifiers or portable CD players. It is not suitable for devices that draw more than 1 A or require a different voltage. Buyers needing higher current or adjustable voltage should look elsewhere.

Simple Tip Swap Installation

Select the matching barrel connector from the ten supplied tips, push it firmly onto the 5.5 × 2.1 mm base plug and connect to the device. The main failure point is choosing a tip with the wrong inner or outer diameter; always verify the device jack dimensions against the listed sizes before powering on. No tools or configuration are required beyond the physical connection.
