⚙️ Technical Specifications Sheet

🧱 Design and Construction Quality

The BMAX B1 Pro features a low-profile chassis reminiscent of a TV box . At just 2.2 cm tall and with a square footprint of 12 x 12 cm, it's an exceptionally slim and discreet device.

The outer casing is made of matte black ABS plastic, with a small decorative strip on the top cover displaying the BMAX logo. Weighing just 220 grams, it can be held effortlessly in one hand.

At its base, we find four non-slip rubber feet and a small door secured by screws that provides direct access to the M.2 bay. The absence of active ventilation slots completely prevents lint or dirt from entering the internal circuits, minimizing long-term cleaning tasks.

🖥️ Screen and Multimedia Experience

In the multimedia field, this device offers a very practical solution for mixed environments thanks to its dual video output:

• Connections: It features an HDMI 2.0 port capable of outputting 4K resolution at 60 Hz and a classic analog VGA port (up to 1080p). This combination is highly valued in offices and schools for connecting older monitors or projectors without having to purchase additional adapters.

• Video playback: Its integrated Intel UHD Graphics 600 features hardware decoding for HEVC (H.265) and VP9 codecs at 1080p and 4K resolutions. In our tests, playback of local 1080p movies or streaming on platforms like Netflix or YouTube at Full HD resolution was smooth. However, when playing 4K content at 60 FPS on YouTube with the modern AV1 codec, the processor usage reached nearly 100% due to the lack of native decoding for that codec.

• Sound: It has a clean analog output via the 3.5 mm jack connector and digital audio via the HDMI cable to the television or monitor.

⚡ Performance, Software and Storage

The BMAX B1 Pro is powered by the Intel Celeron N4000, a 2-core, 2-thread processor that operates at a base frequency of 1.10 GHz and reaches a Turbo frequency of 2.60 GHz.

Operating system behavior

The computer comes with Windows 11 Pro pre-installed. Given its dual-core configuration, the system performs adequately under realistic use: opening one or two applications simultaneously, checking email, editing Excel spreadsheets, or browsing with four to six tabs open. However, attempting heavy multitasking or running multiple demanding programs concurrently results in noticeable slowdowns.

(For this modest hardware, installing lightweight Linux distributions like Lubuntu, Debian, or ChromeOS Flex provides significantly better performance than Windows 11).

Serial storage speed

The standard 128GB of storage is eMMC 5.1, offering sequential read speeds of around 180 MB/s and write speeds of around 110 MB/s. While faster than a traditional mechanical hard drive, it falls short of any SSD. Fortunately, the system includes a free M.2 slot, which drastically improves this situation.

🔌 Energy Consumption and Cables

Energy consumption is the BMAX B1 Pro's strongest point. Thanks to the high efficiency of the Celeron N4000 and the absence of mechanical fans, the electricity consumption measured at the power outlet is negligible.

• Standby/Idle Desktop: 3.8 W – 4.5 W

• Web browsing and basic office skills: 6 W – 8 W

• Full HD video playback: 7.5 W – 9 W

• Maximum load (CPU and GPU stress): 10.5 W – 12 W peak

The included power adapter delivers 12V and 2A (24W), providing ample power. Leaving this mini PC on 24 hours a day for a full month results in an energy cost of less than €1 per month on the electricity bill, making it an ideal candidate for continuous unattended tasks.

🌡️ Temperature and Noise: Actual Thermal Behavior

Because it is fanless , the acoustics of the unit are impeccable: 0 decibels at all times. There are no moving parts or mechanical vibrations.

Temperature behavior

Internal heat is passively dissipated by an internal metal plate that transfers energy to the static ventilation areas of the chassis:

• At rest and during light tasks: The core temperature ranges between 46 °C and 55 °C, with the plastic casing feeling only slightly warm to the touch.

• Under prolonged 100% load: After 40 minutes of maximum demand, the cores reach between 76°C and 82°C. From this point, the chip slightly reduces its maximum frequencies ( soft thermal throttling ) to remain within Intel's safe operating thresholds. It is recommended to place it in an open space and not enclose it in a closed cabinet.

🌐 Connectivity and Extras

Physical and wireless connectivity is well-resolved for its price:

• USB port layout: It has 2x USB 3.0 on one side for fast transfers and 2x USB 2.0 on the other for keyboard and mouse.

• Gigabit Ethernet Network Port: The 1000 Mbps RJ45 connector ensures stable transfers for uninterrupted streaming and downloads.

• MicroSD card reader: Very practical for quickly expanding storage space or transferring photos from cameras.

• Wireless networks: It has dual-band Wi-Fi 5 (2.4 and 5 GHz) and Bluetooth 4.2.

• BIOS features: The BIOS is accessible and includes support for Auto Power On (booting after a power outage) and RTC time scheduling. It lacks a USB-C port and a Kensington security slot.

🛠️ Expansion and Upgrades: What Can We Improve?

Before purchasing this equipment, it is essential to know what can and cannot be modified internally:

• RAM: The 8 GB LPDDR4 memory is soldered to the motherboard. It does not have SO-DIMM slots, so it is not possible to upgrade the RAM under any circumstances.

• SSD Storage: Features 1x free M.2 2280 slot compatible with SATA3 SSD drives up to 1TB or 2TB.

💡 Top recommendation:
The best upgrade you can make to the BMAX B1 Pro is to buy an inexpensive M.2 SATA SSD, install it in the spare bay, and clone the Windows operating system from the stock eMMC storage. The computer will experience significantly faster application launch times.
