📊 Full Technical Specifications

🏗️ Design and Construction Quality

MLLSE G2 Mini PC 

At just 21.95 mm thick and measuring 173.8 × 116 mm, the MLLSE S1 is surprisingly thin for a full-fledged desktop computer. It's roughly the size of an A5 textbook but thinner than most laptops on the market.

The casing is made of ABS plastic with a dark matte finish, giving it a neutral and professional look. There are no excessive decorative elements or RGB lighting, making it suitable for both office and home environments. The port layout on the sides is well thought out: the three USB-A 3.2 ports are easily accessible, and the USB-C port adds modern versatility.

🖥️ Screen and Multimedia

This is the key differentiator of the MLLSE S1 compared to other mini PCs in its class. The device includes its own screen, making it a true portable all-in-one. One actual buyer describes the screen as "bright and easy to read," highlighting it as one of its biggest selling points for the price.

In addition to the integrated screen, it has an HDMI 2.1 output to connect an external monitor when more workspace is needed.

The Intel UHD GPU supports 4K video decoding with AV1 and HDR, ensuring a smooth streaming experience on Netflix, YouTube, or Plex.

🔊 Sound: Built-in speaker

The MLLSE S1 includes a horn-type or cone-shaped speaker (trumpet) that focuses and projects sound forward more directly, similar to how a trumpet amplifies and directs sound. In compact devices like this, it's used to maximize volume and clarity with a very small component.

You don't need to connect external speakers to listen to audio. It's basic for video conferencing, videos, or background music, although for serious audio experiences you'll still prefer external speakers or headphones.

🎙️ "Built-in Microphone": Integrated Microphone

The device also has a built-in microphone, making it completely standalone for video calls on Zoom, Teams or Google Meet without the need for headsets with microphones or external microphones.

In short, the MLLSE S1 is a completely self-contained audio device : it has its own touchscreen, built-in speaker, and microphone. For basic video calls or multimedia use, you absolutely don't need any additional peripherals. 🎯

Features of the MLLSE S1 Built-in Display

📐 7 inch — Screen Size

It's the size of the screen diagonal: 7 inches, equivalent to about 17.8 cm from corner to corner. It's a compact but functional size—similar to a small tablet. For a device measuring 173 × 116 mm, it's exactly what fits on its surface.

🔍 HD — Resolution

HD (High Definition) means the screen has a minimum resolution of 1280 × 720 pixels, although on 7" screens with this label, 1024 × 600 px is more common . It's not Full HD (1920 × 1080), but on a screen of only 7 inches, the visual difference is minimal, since the pixel density is still high.

🎨 IPS — Panel Technology

IPS stands for In-Plane Switching. It's the best LCD screen technology on the market in terms of value for money. Its advantages over TN or VA screens are:

• Up to 178° viewing angle — the image looks perfect from almost any position

• Accurate and consistent colors — no distortion when viewed from the side

• Good color reproduction — ideal for multimedia and everyday work

☝️ 5-Point Touch — Multi-touch Touchscreen

This means the screen is capacitive touch (like a smartphone screen) and can detect up to 5 simultaneous touches. This allows gestures such as:

• Pinch to zoom with two fingers

• Scroll with multiple fingers at the same time

• Windows 11 native touch gestures

It works by connecting internally via USB and normally does not require installing any additional drivers in Windows.

📌 Visual Summary

In short, the MLLSE S1 boasts a truly high-quality touchscreen —not a cheap resistive display, but a capacitive IPS panel like those found in modern tablets. This makes it a genuine touchscreen all-in-one, which is unusual at this price point.

⚙️ Performance and Software

The Intel Twin Lake N150 offers 10 to 20% more performance than the already popular N100, with the same energy efficiency. In everyday use, this translates to:

• ✅ Web browsing: Smooth with 15-20 tabs open

• ✅ Office suite (Office 365, LibreOffice): No slowdowns

• ✅ Video calls (Zoom, Teams, Meet): Stable with HD camera

• ✅ Local or network 4K streaming: Without any interruptions

• ✅ Light photo editing (GIMP, basic Photoshop): Acceptable

• ⚠️ Video editing: Only for lightweight projects in 1080p

Windows 11 comes pre-installed and activated. It's common to find some  factory bloatware, which can be easily removed within the first few minutes of use. Users confirm that the system boots cleanly and without major issues.

🔋 Energy Consumption and Cables

The N150 is one of the most efficient chips on the PC market. With a TDP of just 6W, its actual power consumption in everyday use is minimal.

• Standby power consumption: ~4-6W

• Power consumption under normal use: ~8-15W

• Maximum consumption (sustained load): ~25-30W

• Estimated electricity cost (8h/day): less than €1.5/month

Power is supplied via a dedicated connector ( USB-C for power only, not data) — this is a clever design as it avoids confusion with the USB-C data port. The power supply is included in the box.

🌡️ Temperature and Noise (Actual Thermal)

With such a low TDP and integrated display, thermal management is critical. Based on testing with equivalent hardware:

• Resting temperature: 35-42°C

• Temperature under sustained load: 65-75°C

• Maximum temperature recorded: ~85°C in prolonged benchmarks

The internal fan is barely audible during normal use, making the MLLSE S1 ideal for quiet environments such as libraries, bedrooms, or meeting rooms. Thermal throttling may occur under very long sustained loads, but it doesn't affect everyday use.

🔌 Connectivity and Ports

Dual USB-C connectivity is a standout feature: one port for data/video and another exclusively for charging, preventing conflicts. WiFi 6 ensures greater stability on modern networks compared to competing models with WiFi 5.

🔧 Expansion and Upgrades

The MLLSE S1 is an ultra-compact device with simple but well-defined upgrade options.

⚠️ Important: The slot is M.2 2242 (22 mm × 42 mm). The most common format on the market is 2280 (80 mm long), which is not compatible with this device. Always verify the exact size before purchasing.

💡 Key fact: The slot accepts both SATA and NVMe drives , so when upgrading you can opt for an NVMe M.2 2242 and achieve speeds up to 6 times faster than the factory-installed drive.

💾 Storage: Everything You Need to Know

The MLLSE S1 comes factory-equipped with a 512GB M.2 2242 SATA SSD, housed in a single M.2 slot that supports both SATA and NVMe drives — offering interesting flexibility for future upgrades.

⚡ SATA vs NVMe: What's the Difference?

For typical MLLSE S1 use—office applications, streaming, video calls, and retro emulation—the stock SATA drive is perfectly adequate. The difference with NVMe is only noticeable when moving multi-gigabyte files or working on large video projects.

🔧 Expansion Options

If at any point you need more space or greater speed, you can replace the included disk with:

• 🔹 M.2 2242 SATA 1 TB — More space, same speed (~€20-35)

• 🔹 M.2 2242 SATA 2 TB — Maximum SATA capacity (~€45-70)

• 🔹 M.2 2242 NVMe 1 TB — Higher speed and storage (~€35-55)

• 🔹 M.2 2242 NVMe 2 TB — Maximum capacity and speed (~€65-90)

📊 Real Space Available from the First Start-up

Of the 512 GB of included disk space, Windows 11 and pre-installed software consume approximately 30-50 GB, leaving about 460-480 GB free from the first boot.

💡 Tip: Before replacing the disk, clone the original contents with free tools like Macrium Reflect or Clonezilla to keep Windows 11 activated and all your data without needing to reinstall anything.

🔋 Battery Specifications

⚡ 3.6V / 3,400 mAh — Battery Capacity

• 3.6V is the nominal voltage of the battery cell — standard in lithium (Li-Ion) batteries of this type

• 3,400 mAh is the total capacity in milliampere-hours

• The actual energy stored is: 3.6V × 3.4 Ah = ~12.24 Wh (watt-hours)

For reference, it's a battery with a similar capacity to that of a mid-range smartphone. It's not a large battery, but the N150's very low power consumption (~8-12W) allows you to get the most out of it.

⏱️ 3.5 Hours of Active Use

With the screen on and normal use (office applications, browsing, streaming), the battery lasts approximately 3.5 hours. This is sufficient for:

• ✅ A complete work meeting

• ✅ A class or study session

• ✅ Watch a standard movie (~2 hours)

• ⚠️ Not for a full workday without a plug

😴 24 Hours on Standby

In standby or sleep mode, power consumption drops dramatically and the battery lasts up to 24 hours. This means you can leave the device on standby all night and still have battery life the next day.

📊 Battery Summary

🆚 Comparison with Direct Competitors

The MLLSE S1's built-in screen is its biggest differentiator from its direct competitors. For someone needing a complete setup without buying an additional monitor, the higher price compared to the G2 Pro or the Beelink S13 is more than justified.
