The 18W USB Charger with Quick Charge 3.0 efficiently powers iPhones, Samsung Galaxy devices, Xiaomi, and Huawei phones via three ports. Its adaptive voltage (3.6V–20V) reduces charging time by 38% compared to standard chargers. EU/US plug variants and multi-protection systems make it a universal, safe choice for travelers and multi-device households.
How Does the JK Active Balancer Optimize Battery Performance?
How Does Quick Charge 3.0 Improve Charging Speeds?
Quick Charge 3.0 uses Intelligent Negotiation for Optimum Voltage (INOV) to adjust power delivery dynamically. This reduces charging time for a 3300mAh battery from 0% to 80% in 35 minutes. Compatible devices experience 4x faster charging than conventional 5W adapters while minimizing heat generation.
Which Devices Are Compatible with This 3-Port Charger?
The charger supports iPhone 8–15 series (18W PD), Samsung S10–S23 (AFC), Xiaomi Redmi/Note series (QC3.0+), and Huawei P30/Mate 20 (FCP). Non-QC devices like AirPods and tablets receive 5V/2.4A power. Third-party testing confirms simultaneous charging of iPhone 14 (50%), Galaxy S22 (30%), and wireless earbuds (20%) without overload.

- Does It Work with iPhone 15’s USB-C Port?
- Yes, the USB-C port delivers 9V/2A (18W) PD to charge iPhone 15 to 50% in 30 minutes. Legacy Lightning cables work via USB-A ports at 5V/2.4A.
- Can I Leave It Plugged In Overnight?
- Safety certifications allow 24/7 use. Overcharge protection stops current when devices reach 100%, reducing battery wear. Average standby power consumption is 0.05W.
- What’s the Warranty Period?
- 18-month warranty covering manufacturing defects. Stress-test data shows 95% of units function beyond 3 years with daily use.
