MEAN WELL GST25E18-P1J 25 W 18 V DC 1.39 A AC/DC Power Supply with EU Plug and 2.1x5.5mm DC Connector

The GST25E18-P1J stands out among compact AC/DC adapters by pairing a generous 25-watt output with an 18-volt DC rail and a standard 2.1x5.5 mm barrel plug, all in a lightweight plastic housing that runs cool under full load. Unlike many wall-mounted units that sacrifice efficiency for size, this model meets Level VI (DOE) requirements and consumes less than 0.075 W at no load, making it an ideal choice for always-connected devices such as routers, LED strips, or small industrial controllers.

Highlights

• 25 W output power with 18 V DC / 1.39 A rating
• Wide input range: 90–264 V AC, 47–63 Hz
• Level VI energy efficiency, <0.075 W standby consumption
• Class II double insulation, no earth connection required
• Protections: short circuit, overload, over voltage
• EU AC plug, 2.1x5.5 mm centre-positive DC connector
• Safety certifications: UL/cUL, GS, RCM, PSE, KC, CCC, EAC, CE, FCC

In daily use

Thanks to its free-air convection cooling, the GST25E18-P1J operates silently from -30 °C to +70 °C, so it can be installed in enclosed spaces without derating concerns. The output remains stable with line regulation of ±0.5% and load regulation of ±5%, while ripple and noise stay below 150 mVp-p. The 2.1x5.5 mm DC plug fits a wide range of equipment, and the EU AC plug means it is ready for European sockets out of the box.
