The Muti 4 Ports 120W Charger is a high-speed wall adapter featuring USB-C Quick Charge 3.0 and Power Delivery (PD) for simultaneous fast charging of up to four devices. Compatible with iPhone 15, Samsung Galaxy phones, and other USB-C gadgets, it prioritizes safety with overcurrent protection and adaptive power distribution. Ideal for multi-device households.
How Does the JK Active Balancer Optimize Battery Performance?
How Does the 120W Power Output Enhance Charging Speed?
The 120W total power enables rapid charging across all four ports. Using Dynamic Power Distribution, the charger allocates up to 30W per USB-C port for PD-compatible devices like iPhone 15, reducing charging time by 50% compared to standard adapters. For Quick Charge 3.0 devices like Samsung Galaxy, it delivers 18W optimized bursts while preventing overheating.
This intelligent power management system automatically detects connected devices through voltage handshakes. When charging two iPhones simultaneously, each receives 27W through USB-C ports while two additional devices get 15W via USB-A. The charger’s 95% conversion efficiency minimizes energy waste – only 6W is lost as heat during full-load operation. Independent lab tests show it can charge an iPhone 15 Pro Max to 80% in 35 minutes while simultaneously powering a MacBook Air at 45W.

What Safety Features Prevent Overheating Damage?
Six-layer protection includes temperature control chips, fused ceramic heat sinks, and auto-resetting fuses. The charger monitors port temperatures every 0.4 seconds, throttling power if any port exceeds 113°F (45°C). Reinforced casing withstands 248°F (120°C) without deformation, meeting UL 60950-1 safety standards.
The thermal management system uses three distributed sensors that create a real-time heat map of the internal components. During stress tests, the charger maintained safe operating temperatures even when pushing 120W continuously for 72 hours. The ceramic cooling plates dissipate heat 3x faster than traditional aluminum heatsinks, while the fire-retardant PC+ABS shell material meets V-0 flammability ratings. A dedicated surge protection module can absorb up to 6kV voltage spikes from unstable power sources.
“This charger’s use of GaN II technology and adaptive thermal management sets a new benchmark. Most competitors can’t dynamically reallocate wattage without manual port selection. The inclusion of foreign plug adapters at this price point is disruptive – it effectively replaces four separate chargers in a traveler’s kit.”
