When choosing a motorcycle USB charger, waterproof rating is one of the most important parameters consumers care about. What do IP67, IP65 and IPX7 actually mean? How do you choose the right waterproof rating for your usage scenario? This article answers these questions one by one.
What Are IP Ratings?
The IP (Ingress Protection) rating system, defined by the IEC, indicates how well electrical equipment is protected against solid objects and water. The two digits after IP represent:
- First digit: dust protection (0-6, with 6 being the highest)
- Second digit: water protection (0-9K, with 9K being the highest)
Motorcycle Usage Scenarios
Motorcycle USB chargers are mounted near the handlebar and are exposed to:
- Rainwater while riding in wet weather
- High-pressure water jets during car washes
- Moisture condensation in humid environments
- High summer temperatures and direct sunlight
