Introduction

When traditional chargers were plagued by issues such as bulkiness and excessive heat, L Lab broke new ground with GaN technology, launching three ultra-slim fast-charging models: 30W, 45W, and 67W. Through technological innovation, these products elevate charging efficiency, portability, and thermal control to new heights. Featuring millimeter-thin bodies across the entire lineup, they redefine the charging experience. With intelligent protocol recognition and low-temperature fast charging technology, they deliver seamless charging support for mobile devices.

L Lab Charger Selection Guide

L Lab’s three GaN chargers all support a wide voltage range of 100–240V and are compatible with multiple fast-charging protocols, including PD, QC, and PPS. They offer compact size, high power density, and high conversion efficiency. All models have passed multiple safety certifications such as CE, RoHS, FCC, and CCC, ensuring outstanding quality and reliability.

L Lab 30W Ultra Slim GaN Charger

As the world’s thinnest 30W GaN charger, this device features a self-developed transformer system and an innovative structural design that achieves a slim profile of just 1.4 cm, only one-third the size of Apple’s 20W charger, yet delivering 50% more power. With a power density of 1.13W/cm³, it sets a new benchmark in compact performance. Its precise industrial design also overcomes regulatory constraints for EU plug dimensions, seamlessly integrating the plug with the charger body for a sleek, unified look.

In thermal management, it introduces a 3D cooling system constructed with nano-grade graphene materials. This active heat dissipation structure minimizes energy loss from heat by 20%, while passive convection cooling maintains surface temperatures 10–15°C lower than similar products during fast charging.

Despite its ultra-slim build, it boasts broad compatibility, supporting fast-charging protocols for a wide range of smartphones and delivering up to 30W PD fast charging for laptops in emergency scenarios. Perfect for business travel, it easily replaces bulky traditional adapters, offering the freedom of "one charger for all." Combined with a minimalist and stylish design, it truly merges high performance with a refined user experience.

L Lab 45W EURO Slim GaN Charger

The L Lab 45W EURO Slim GaN Charger features an ultra-slim and sleek design, with a thickness of just 15.5mm. Its lightweight and compact form offers exceptional portability, making it an ideal companion for both daily commutes and business travel. With a low-profile, modern aesthetic, it blends seamlessly into various usage scenarios, balancing functionality with visual appeal.

Equipped with L Lab’s proprietary circuit design, the charger combines active thermal management with a fully encapsulated nano-graphene passive heat dissipation system. This ensures stable, full-power output over extended periods while effectively minimizing heat buildup, delivering enhanced safety, durability, and peace of mind.

Built with a multi-protocol fast-charging chip, it fully supports PD 3.0, QC 4.0, and 45W PPS protocols. It’s especially optimized to meet the fast-charging needs of Samsung’s S series devices, offering noticeably improved charging efficiency. Whether you're charging a smartphone, tablet, or ultra-thin laptop, users can enjoy a seamless, fast-charging experience with comprehensive safety and long-term reliability.

L Lab 67W EURO Slim GaN Charger

The L Lab 67W EURO Slim GaN Charger is currently the thinnest 67W charger on the market. With a thickness of just 1.34 cm—comparable to mainstream smartphones—and a volume only one-third that of Apple’s 70W charger, it delivers outstanding portability. Featuring a minimalist design language and equipped with a Navitas core planar transformer, it maintains cool operation throughout the entire charging process, offering users a “small size, big power” experience.

Built on L Lab’s independently developed architecture, this charger integrates next-generation GaN components from top global manufacturers to achieve sustained, stable 67W output—overcoming long-standing industry limitations. Its energy efficiency is particularly impressive, with peak efficiency reaching 95% and power loss reduced by 50%. Thanks to its dual thermal management system, including active heat dissipation, it cuts heat loss by 20–30%, keeping surface temperatures 10–15°C lower than competing products. It sets a new industry benchmark in power, efficiency, and thermal control—delivering high performance without overheating.

The charger supports major fast-charging protocols including PD, QC, and PPS, with intelligent device recognition to dynamically adjust the optimal charging profile. It offers broad compatibility with smartphones, tablets, and laptops. Its full 67W output is stable and uncompromised, even when powering high-performance laptops, delivering reliable, maximum-speed charging every time.
