Ultra-Compact 5 W USB Wall Plug Adapters Meet Level VI Standards

TUALATIN, Ore. — CUI Inc announces a line of ultra-compact 5 W wall plug adapters for the US, Japanese and European markets featuring an integrated USB connector. The SWI5-5-N-I38 and SWI5-5-E-I38 are designed to meet the stringent average efficiency and no load power requirements mandated by the US Department of Energy (DOE) set to go into effect on February 10, 2016. The new Level VI standards aim to significantly lower the amount of power consumed when the end application is not in use or is no longer connected to the system.  Any domestic or global manufacturer seeking to market their end product with an external adapter in the US must meet these new performance standards.

With a footprint as small as 2.56 x 1.42 x 0.89 inches (64.92 x 36 x 22.5 mm) these adapters are among the industry’s smallest ac-dc power supplies to integrate a USB connector. The ultra-compact design makes it ideally suited for a wide range of consumer applications, including media players, e-readers, GPS and other mobile devices.

The 5 W adapters both feature 5 Vdc single regulated outputs with a wide universal input voltage range from 90~264 Vac. The series also features no load power consumption <0.075 W and provides over voltage, over current and short circuit protections.

Designed with input blades for North American and Japanese applications, the SWI5-5-N-I38 offers 60950-1 UL/cUL and PSE safety approvals while the SWI5-5-E-I38 with European input blades offers GS safety approvals. All models meet Class B limits for conducted and radiated emissions.

The new SWI5-5-N-I38 and SWI5-5-E-I38 are available immediately with prices starting at $5.36 per unit at 100 pieces through distribution. Please contact CUI ( for OEM pricing.
