What is the UL2089 Report for Car Chargers?

Car chargersrefer to chargers poweRED conventionally by a vehicle’s battery (12V for cars, 24V for trucks). They are widely used for charging lithium batteries in various portable and handheld devices. Car chargers serve as convenient accessories that allow vehicle owners to charge their digital devices anytime and anywhere using the car’s power supply. Some high-end car chargers typically include two USB ports, enabling simULtaneous charging of two digital devices.

Why is the ul report Necessary?

The United States enforces very strict safety requirements. Domestic electronics manufacturers have been required to conduct relevant safety tests for many years. With Amazon’s growing strategic role in e-commerce, an increasing number of foreign electronic devices have entered the US market via Amazon. However, the US does not mandate compulsory safety testing for foreign manufacturers.

Following a series of electronic device fire incidents, on September 24, 2017, US authorities issued a law specifically targeting e-commerce platforms. This law requires Amazon to notify foreign sellers on its platform to provide relevant safety reports. Sellers must submit UL standard test reports before resuming sales; otherwise, Amazon must order a suspension of sales.

About UL2089

UL2089 is a safety testing standard specifically for car charger products. Currently, Amazon mandates that sellers provide safety certification reports, specifically the UL2089 test report, to protect consumers’ rights. This report must be submitted to Amazon’s backend to allow products to be listed and sold normally.

UL2089 is a certification standard introduced by Underwriters Laboratories (UL) in the United States for car USB power adapters. It ensures the safety and reliability of the product during use. UL2089 certification involves rigorous testing and evaluation of electrical safety, electromagnetic compatibility, insulation performance, and more, ensuring the car charger’s safety under normal and abnormal conditions.

1. Maximum Output Voltage Test

2. Power Input Test

3. High and Low Temperature Test

4. Dielectric Voltage-Withstand Test

5. Fault Test

6. Resistance to Crushing Test
