Origins: A Safety Revolution Born from Necessity
In 2019, as global EV adoption soared by 40% annually, electrical engineer Mr. Lam uncovered a critical flaw: most available chargers prioritized cost over safety. "How can we trust our homes and vehicles to substandard equipment?" he asked.
Determined to change the status quo, Mr. Lam assembled a team of seven veteran electrical engineers and founded InPlugin in Canton. InPlugin combines “Intelligent” and “Plug-in,” representing our commitment to innovation and our mission to protect lives through advanced charging technology.
Our Safety-First Approach: Embedding Safety into Every Charge
At InPlugin, we believe that every flow of electricity carries not just energy but the responsibility of safety. To address the key concerns of EV owners, we have built our products around a Five-Layer Safety Philosophy:

1. Non-Toxic, Fireproof Materials

2. Durable Craftsmanship
- Ultrasonic Welding: InPlugin chargers feature ultrasonic welding, ensuring strong, secure joints that resist corrosion and damage.
- High-Performance Contacts: Our silver-plated(5μm coating, 2x thicker than average) contacts significantly improve electrical conductivity, reducing risks of overheating and ensuring long-term reliability.

3. Intelligent Multi-Layered Circuit Protection
- Accurate Monitoring: Detect even <1% voltage deviations with 10ms response time.
- Integrated Leakage & Surge Prevention: Our chargers offer automatic shutdown for leaks (≥30mA), surges (8,000W+), and short circuits. (3x faster thanIEC 62955).
- Instant Grounding: Safety features automatically ground the circuit to prevent fires and shocks.

4. Real-Time Thermal Monitoring
- Dual Sensors: Continuous monitoring of connector and relay temperatures.
- Over-Standard Wire: Featuring thicker pure copper wiring , this design reduces heat buildup by 30% and delivers enhanced durability for a longer lifespan.

5. Extreme Climate Resilience
- 72-Hour Stress Tests: Every unit undergoes rigorous testing at temperatures from -35°C (–31°F) to 55°C (131°F).
- IP66 Waterproofing: Validated under extreme conditions, including monsoon simulations.

Certified Safety and Quality Standards
InPlugin EV chargers are certified by trusted international standards organizations, including CE, TÜV Rheinland, UKCA, RoHS, FCC and ETL. These rigorous certifications confirm our chargers' safety, reliability, and compliance with global safety norms.
