Can Your Wireless Charger Handle -15°C for 48 Hours?


Low temperature testing evaluates whether a wireless charger can maintain its performance, reliability, and durability in cold environments. It is especially important for products designed for vehicles, outdoor applications, and markets with cold climates.

Why Is Low Temperature Testing Important?

Extreme cold can affect electronic components, materials, charging performance, and overall product reliability.
Low temperature testing helps verify:
  • Stable product performance in cold conditions
  • Material and component durability
  • Normal charging and functional operation
  • Reliability during long-term exposure to low temperatures

How Do We Perform the Test?

Test Condition: -15°C for 48 hours
  1. Check that all product functions work normally before testing.
  1. Set the environmental chamber to -15°C for 48 hours, then place the sample inside.
  1. After testing, remove the sample and leave it at room temperature for 1 hour.
  1. Check the product's functions, materials, and overall performance.

What Makes the Test Qualified?

The test is considered PASS when the product maintains normal functions and shows no abnormality after the test.
Test Result: PASS
The sample maintained normal materials and functions after -15°C / 48-hour low temperature testing.
