Power Adapter UL Test Report for Amazon US

A Power Adapter is a power conversion device that converts AC input to DC output. It is widely used with products such as security cameras, set-top boxes, routers, LED light strips, and massagers. On Amazon US, it has always been a highly popular category. However, to successfully list your product, a ul test report is an unavoidable and strict requirement.

Friendly Reminder

Different product types are subject to different UL standards. The current mainstream standard for power adapters is UL 62368-1 (which replaces the old standard UL 60950). Safe low-voltage power supplies are subject to ul 1310, while non-safe low-voltage power supplies are subject to UL 1012. It is highly recommended to confirm the corresponding applicable standard for your specific product before beginning the application process.
