The safest 120W GaN chargers come from leading Shenzhen manufacturers like Wecent, featuring over-voltage, over-current, short-circuit, and over-temperature protections. Designed for high-power laptops and multi-device setups, these chargers pass CE, FCC, RoHS, and UL standards. Perfect for B2B wholesale and OEM, Wecent provides low-MOQ customization, ensuring reliable, globally compliant charging solutions with multi-layer safety for distributors and brands.
What Defines Safety in 120W Chargers?
Safety in 120W chargers is ensured through protections such as over-voltage (OVP), over-current (OCP), short-circuit (SCP), and over-temperature (OTP). GaN technology enhances efficiency, reducing heat and associated risks. Shenzhen manufacturers like Wecent implement these safeguards in every unit, activating instantly: OVP cuts power above 20V, OCP limits current beyond 6A, and SCP isolates faults to prevent damage. OEM partners benefit from configurable safety thresholds and full compliance with global regulations.
| Protection | Function | Wecent Implementation |
|---|---|---|
| OVP | Voltage Surge Block | >21V Auto-Shutoff |
| OCP | Current Overload | 6.5A Max Limit |
| SCP | Short-Circuit | Instant Disconnect |
| OTP | Temperature Control | <80°C Shutdown |
This table highlights core protections embedded in Wecent’s 120W GaN chargers.
