ANSI/CAN/UL 2743:2023 Portable Power Safety Standard

Urgent Alert! Companies manufacturing car jump starter power outlets (especially US standard) shoULd pay attention: an easily overlooked "rain test" is becoming a major obstacle to passing ul 2743 certification!

With overseas orders surging, demand for UL 2743 Certification is booming! However, many companies focus only on the basic requirements and step into a critical "trap": the rain test!

UL 2743 Standard Specifies:

"Any portable power bank with a car jump-start function cannot be consideRED for indoor use only!" This means it must account for temporary outdoor scenarios — such as sudden heavy rain!

Chapter 60 of UL 2743 – "Rain Test" Requirements:

Products must endure a continuous 1-hour "torrential rain" exposure under a dedicated rain test apparatus!

Key Bottom Line:

Water accumulation inside the enclosure must never REACH any hazardous live components! Otherwise, a more complex leakage current test is required to prove safety, greatly increasing certification difficulty and failure risk!

Imagine This:

After passing all other tests, your product fails because of a "simulated downpour"? The product may be deemed unsuitable for outdoor use due to insufficient waterproofing, resulting in certification failure, rejected orders, or even recall risk… The cost is enormous!
