The WLXG3 is the highest-output model in this desktop charging station series, delivering USB Power Delivery 3.1 at 140W on two ports simultaneously — the standard required by MacBook Pro 16″, high-end Windows laptops, and any device that benefits from Extended Power Range (EPR) charging. Six ports total, a vivid color display, and a GaN chip with integrated temperature management are packed into a chassis approximately 20% smaller than competing 140W desktop chargers on the market.
Where the WLX60C and WLX60D are optimised for home desks and gaming setups up to 100W, the WLXG3 is engineered for professional power users, multi-laptop households, meeting rooms, and commercial environments where two laptops may need simultaneous 140W charging alongside phones, tablets, and accessories. The color display shows per-port voltage and current in real time; a single touch of the top button switches to a total-output ring view showing combined wattage across all active ports.

Full Product Description
PD 3.1 — Why 140W Matters
USB Power Delivery 3.1 introduced Extended Power Range (EPR), allowing chargers to operate at voltages above 20V — up to 28V at 5A for a maximum of 140W. This is required to charge MacBook Pro 16″, Dell XPS 15/17, ASUS ROG Zephyrus, Lenovo ThinkPad X1 Extreme, and other power-intensive devices at their maximum rated speed. Standard PD 3.0 is capped at 100W. The WLX-G3 supports PD 3.1 on C1 and C2 simultaneously — making it capable of fast-charging two 140W devices at the same time from a single unit.
Color Display — Six Ports, Complete Visibility
The front-facing color display shows a 6-panel grid in its default Main view: each port tile displays live voltage and current. Active high-power ports are highlighted in yellow; standard-power ports in blue; inactive ports show dashes. A user can verify at a glance that their MacBook is receiving 15V/3A, their phone 9V/2A, and their earbuds are idle — no app, no additional hardware. One touch of the top button switches to the Ring view: a circular gauge showing total combined output (e.g. 180W), useful for understanding overall system load.
Compact Despite 140W — The GaN Advantage
A 140W silicon-based charger requires significant thermal management hardware due to heat generated at high switching frequencies. GaN switches faster and generates less heat, enabling a more compact transformer. The WLX-G3 achieves approximately 20% smaller volume than competing 140W desktop stations at just 100x84x49.7mm and 546g. For a charger capable of simultaneously powering two high-performance laptops, this is a meaningful size advantage — particularly for shared desk and meeting room deployments. Know more about the GaN Charger OEM Manufacturer.
Protocol Coverage — Every Major Brand
The WLX-G3 covers PD 3.1 and PD 3.0 for Apple and USB-C laptop users, QC 3.0 for Qualcomm-based Android devices, PPS for Samsung adaptive charging, SCP for Huawei, and AFC for older Samsung models. BC 1.2 and Apple 2.4A cover legacy accessories. In practice: Apple, Samsung, Huawei, Xiaomi, Dell, HP, Lenovo, ASUS — any device, any brand, maximum speed.
Built for Professional and Commercial Environments
Dual 140W PD 3.1 ports, dual 100W PD 3.0 ports, and two QC 3.0 USB-A ports make the WLX-G3 ideal for meeting rooms, executive workspaces, co-working spaces, and hotel premium suites. One unit on a conference table can handle two attendees’ laptops at 140W each while charging four additional devices simultaneously — replacing six individual chargers with a single compact, professional-looking station.
Target Use Cases
- MacBook Pro 16″ / high-power laptop users: True 140W PD 3.1 at maximum rated speed — no compromise
- Dual-laptop households: Two laptops at 140W simultaneously from one unit
- Meeting rooms / conference tables: 2 laptops at 140W + 2 tablets at 100W + 2 phones at 30W — one unit serves a full room
- Hotel premium suites: Any guest device, any protocol, maximum speed
- Executive / corporate gifting: Premium display and 140W capability make a strong impression
- Power-user home offices: Permanently replaces laptop charger + phone charger + tablet charger
- OEM for laptop accessory brands: Position alongside high-end laptop lines; private label available
Frequently Asked Questions (FAQ)
Q: What is PD 3.1 and why does it matter?
A: PD 3.1 introduced Extended Power Range (EPR), enabling voltages above 20V — up to 28V/5A for 140W. This is required to fast-charge MacBook Pro 16″ and select high-performance Windows laptops at their rated maximum. Standard PD 3.0 is capped at 100W (20V/5A). The WLX-G3 supports PD 3.1 on C1 and C2.
Q: Can I charge two MacBook Pro 16″ laptops simultaneously?
A: Yes. C1 and C2 each support up to 140W via PD 3.1. Two MacBook Pro 16″ units can charge simultaneously at full speed. C3 and C4 simultaneously serve two additional devices at up to 100W each, and A1/A2 handle phones and accessories at 30W each.
Q: What does the display show?
A: The color display has two views. Main view: a 6-panel grid with live voltage and current for each port (C1-C4, A1-A2) — yellow tiles for high-power ports, blue for standard, dashes for idle. Ring view: total combined output wattage as a circular gauge (e.g. 180W). Press the top touch button to switch between views.
Q: How do I switch the display view?
A: Touch the button on the top surface of the unit once. This toggles instantly between the 6-port Main view and the Ring view. No hold, no settings menu, no app required.
Q: Which devices and brands are compatible?
A: PD 3.1, PD 3.0, QC 3.0, PPS, SCP, AFC, BC 1.2, and Apple 2.4A are all supported. This covers Apple (MacBook, iPhone, iPad), Samsung (all fast-charge protocols), Huawei (SCP), Xiaomi, Dell, HP, Lenovo, ASUS, and virtually every major consumer electronics brand.
Q: How much smaller is the WLX-G3 than a standard 140W charger?
A: Approximately 20% smaller in volume, measuring 100x84x49.7mm and weighing 546g. This reduction is achieved through GaN technology, which runs more efficiently and generates less heat than silicon at the same output.
Q: What is the total maximum combined output?
A: Individual port maximums are: C1 140W, C2 140W, C3 100W, C4 100W, A1 30W, A2 30W. Total combined output under simultaneous full-load use should be confirmed with your supplier, as it depends on shared power budget management.
Q: What safety protections are included?
A: Over-voltage, over-current, short-circuit, and over-temperature protections are standard, with GaN chip integrated thermal management. CE and FCC certifications apply. Additional regional certifications available on request.
Q: Is the WLX-G3 available for OEM/ODM customization?
A: Yes. Full OEM/ODM services available including unit branding, packaging design, and color customization. Contact darren@gancharge.com or WhatsApp +86 18923789351 for MOQ, lead times, and options.
Q: What plug types are available?
A: US and EU are confirmed. Additional plug options (UK, AU) should be confirmed directly with the supplier for your target market.
