Teamgee 12″ Laptop Screen Extender, Dual Display Triple Setup
Discover how the Teamgee Portable Monitor transforms scatterbrained productivity into a graceful symphony—two extra screens for your laptop, minus the chaos.
The Teamgee S1 is a single-panel 14-inch laptop screen extender that turns a laptop into a dual-screen setup. Not triple. One additional screen. That simplicity is its advantage: lighter at 2.34 lbs, thinner at 0.9 inches folded, and fewer cables needed than triple extenders. It attaches with adjustable brackets and anti-slip stoppers, with a built-in kickstand that adjusts in both angle and length. The matte IPS panel has 1080P resolution, 300 nits, 72% NTSC, 1000:1 contrast, 178° viewing angles, 3ms response, FreeSync, and built-in stereo speakers at 60Hz. Fits 13-17 inch laptops. Plug & Play via USB-C or HDMI + USB-A. No drivers. Eye comfort mode. 1-year warranty.
Manufactured by Shenzhen Baijiayoupu Technology Co., Ltd., the same company behind KEFEYA, Cenerius, Kakuka, and Laptomo.

Teamgee 14” Laptop Screen Extender, S1 Dual FHD IPS Portable Monitor for 13–17” Laptops, USB-C/HDMI Plug & Play, Compatible with Windows, macOS & Android, Perfect for Hybrid Work & Travel
Why One Screen Instead of Two
Triple extenders add two screens but also add weight (3-5 lbs typical), bulk, more cables, and more power draw. The S1 adds one screen at 2.34 lbs. For users who need one additional screen for reference material, a video call, or a document beside their main work, the dual setup covers that without the complexity of a triple. The lighter weight and thinner folded profile (0.9 inches) make it more practical for daily commuting than most triples. If you actually need three screens, this is not the product. If you need two and want to travel light, it is. For a Teamgee triple extender
Matte, FreeSync, and 3ms
The matte finish is a practical advantage over glossy competitors, especially for a screen that travels to different lighting environments. No reflections in coffee shops, bright offices, or near windows. FreeSync reduces tearing during video and casual gaming. 3ms response at 60Hz provides clean motion for scrolling, video playback, and light gaming. That combination of matte + FreeSync + 3ms is uncommon in the single-panel extender category and makes the S1 more versatile than most. For USB-C requirements, see our USB-C portable monitor guide.
Attachment System
The S1 uses adjustable brackets with anti-slip stoppers to attach to the laptop, plus a built-in kickstand that adjusts in angle and length. The bullets describe this as a system that “holds steady” and “stays solid.” The 0-180° rotation allows screen sharing and presentation use. The wide laptop fit range (13-17 inches) means the adjustable brackets accommodate different sizes without needing model-specific adapters.

Who This Extender Is For
Daily commuters and travelers who want one extra screen without the bulk of a triple setup: 2.34 lbs, 0.9 inches folded, matte IPS, FreeSync, 3ms, stereo speakers, 300 nits, and a secure attachment system with adjustable brackets. If your workflow needs a second screen for reference, calls, or documents beside your main work, the S1 provides that at a weight and size that fits in a backpack daily. For a different Baijiayoupu brand with triple screens, see the KEFEYA 14 inch FHD IPS review.
Users who need triple screens or higher resolution: The S1 is a single additional screen at 1080P. For triple setups or higher resolution, our comparison pages cover options.
Final Verdict
The Teamgee S1 does one thing well: adds a quality second screen to a laptop without adding unnecessary weight or complexity. Matte IPS at 300 nits, 72% NTSC, 3ms, FreeSync, stereo speakers, eye comfort mode, and a secure attachment system at 2.34 lbs and 0.9 inches folded. The wide 13-17 inch laptop compatibility, Plug & Play, and three-cable kit cover most setups. Baijiayoupu manufacturing provides proven production behind the Teamgee brand.
It is one screen, not two. That is by design, not a limitation. For users whose daily workflow benefits from a second screen and who carry their setup every day, the S1 provides that in the lightest, simplest package from the Baijiayoupu family. For users who need more screens or more resolution, other products in the family address those needs.
Frequently Asked Questions
Why dual instead of triple?
One additional screen weighs less, folds thinner, needs fewer cables, and draws less power than two additional screens. If your work needs a second screen for reference while your main screen handles the primary task, dual is sufficient and more portable.
Does it work with MacBook M2?
The listing does not mention M-series exclusions. However, the manufacturer (Baijiayoupu) typically excludes base M1/M2/M3 across its other brands (KEFEYA, Cenerius, Kakuka). Contact Teamgee to confirm your specific Mac model before purchasing.
How does it attach to the laptop?
Adjustable brackets with anti-slip stoppers clamp to the laptop lid. A built-in kickstand adjusts in angle and length for additional stability. The system accommodates laptops from 13 to 17 inches.
