1. Project Overview

Gallium nitride (GaN) fast chargers keep evolving toward miniaturization, high power density and superior reliability. As the critical power transmission component, interface connectors face stringent requirements in structural space utilization, continuous high-current load capacity and long-term plug-unplug durability.

Lenovo launched its original 68W single USB‑C PD GaN fast charger adapter equipped with JSXCONN side-entry Type‑C female connector. The design achieves compact enclosure arrangement and stable delivery of peak 68W power, supporting fast charging for slim laptops, tablets, smartphones and other digital devices.

2. End Product Introduction

Leveraging the advantages of third-generation GaN semiconductors, Lenovo 68W Single USB‑C GaN Fast Charger Adapter realizes a compact and lightweight form factor.

1.Peak power output up to 68W;

2.Natively supports mainstream fast charging protocols including PD3.0 and PPS, compatible with Lenovo slim notebooks, flagship Android smartphones, tablets and more;

3.Comprehensive protection circuits against overvoltage, overcurrent and overheating, complying with strict safety standards for consumer power supplies;

4.Single Type‑C port design suitable for mobile office and daily digital charging scenarios.

3. Selected Connector: JSXCONN Side-Entry Type‑C Female Connector (Red Insulator)

Product Highlights

1.Side-entry horizontal structure optimized for compact GaN charger housings

Adopting side-entry DIP through-hole configuration, it optimizes internal PCB layout of chargers and reduces vertical space occupation, perfectly catering to the miniaturization trend of GaN fast chargers.

2.Distinctive high-temperature-resistant red LCP insulator

Manufactured with high-performance high-temperature LCP plastic to resist deformation during reflow soldering. The distinctive red insulator enables easy visual identification on production lines, lowering risks of wrong component assembly.

3.Stable high-current transmission for 68W high-power fast charging

Terminals are precision-stamped from high-conductivity copper with optimized contact geometry. Low contact resistance and controllable temperature rise under continuous high-current operation ensure steady PD protocol communication without intermittent charging or power switching faults.

4.Outstanding mechanical durability

Subjected to plug-unplug cycle testing in accordance with USB-IF standards. It delivers consistent insertion/extraction feel and maintains stable spring tension after thousands of insertions and removals, resisting loosening for frequent daily use of chargers.

5.Proven manufacturing capacity to guarantee mass delivery

Guangdong JSXCONN Industrial Co., Ltd. implements full in-house production covering mold development, precision stamping, injection molding, electroplating and finished product testing. All products comply with RoHS environmental directives to support stable large-volume supply.
