The 120W Fast Charger with 4 ports combines Quick Charge 3.0, USB-C Power Delivery, and 6A cable support to charge multiple devices like Samsung, iPhone, Xiaomi, and OPPO simultaneously at high speeds. Its EU/US plug compatibility and adaptive voltage distribution make it a versatile solution for travelers and households.

How Does 120W Charging Enhance Device Power-Up Speed?
120W charging divides power dynamically across four ports, delivering up to 30W per port. This enables rapid charging for laptops (via USB-C PD) and phones (via QC3.0). For example, a Xiaomi 12 Pro reaches 50% in 15 minutes. The charger prioritizes power-hungry devices first while maintaining safe temperature levels through built-in surge protection.
The adaptive power distribution algorithm detects device types through handshake protocols. When charging a laptop (45W) and three phones (25W each), the system allocates 45W to the laptop and splits remaining power as 25W+25W+25W. This contrasts with lower-wattage chargers that struggle with multi-device loads. The table below shows common charging scenarios:
| Device Combination | Power Allocation | Total Output |
|---|---|---|
| 1 Laptop + 3 Phones | 45W + 25W + 25W + 25W | 120W |
| 4 Tablets | 30W x 4 | 120W |
| 2 Laptops | 60W + 60W | 120W |
Which Devices Support Quick Charge 3.0 Technology?
Compatible devices include Samsung Galaxy S10-S23 series, Xiaomi Redmi Note 12 Pro, OPPO Reno8, and iPhone 12-15 (using PD). Quick Charge 3.0 increases voltage up to 20V while adjusting output in 200mV increments, reducing heat by 45% compared to QC2.0. Non-compatible devices receive standard 5V/2.4A charging without triggering fast-charge protocols.

Why Is GaN Technology Missing in This Charger?
This model uses traditional silicon transistors instead of GaN (Gallium Nitride) to keep costs 40% lower. While slightly larger, it achieves 85% energy efficiency versus GaN’s 92%. Heat dissipation relies on a graphite-coated aluminum heatsink, maintaining surface temps below 45°C during 4-device charging. Future versions may integrate GaN for reduced size and higher 140W output.
The decision to use silicon reflects a balance between performance and affordability. GaN chargers typically cost $25-$50 more due to complex manufacturing. For users needing occasional high-wattage charging, the savings outweigh minor size differences. The table below compares key parameters:
| Feature | Silicon Charger | GaN Charger |
|---|---|---|
| Efficiency | 85% | 92% |
| Size | 3.1″ x 2.4″ | 2.2″ x 1.8″ |
| Cost | $59.99 | $99.99 |
“The 120W 4-port charger fills a niche for budget-conscious power users. While lacking GaN, its adaptive power distribution rivals premium brands. The inclusion of a 6A cable is strategic – most users overlook cable specs, which bottleneck performance. I’d recommend it for family/office setups where simultaneous charging outweighs portability needs.”

FAQ
- Does it work with iPhone 15 Pro Max?
- Yes, using the USB-C port and a compatible USB-C to USB-C cable. It delivers 27W via USB-PD, charging the iPhone 15 Pro Max to 50% in 30 minutes.
- Can it charge a MacBook Pro?
- Only MacBook Pro 13” (61W) and Air (30W). The 16” MacBook Pro requires 96W+ chargers. This 120W adapter can power the 13” model at 45W when three other ports are idle.
- Is overheating common during 4-device charging?
- Surface temps reach 43°C – warm but safe. The charger auto-throttles output by 15% if internal sensors detect 65°C+ components, prioritizing safety over speed.
