Acer TravelMate Spin B3 review: Robust 2-in-1 laptop with pen input

Versatile. Acer's 2-in-1 device offers silent operation, a good battery life, and an NVMe SSD. The touchscreen can be operated either with your fingers or with the included input pen. Windows 10 Pro serves as the operating system, and it can be updated to Windows 11. The price is about 330 € (~$375).

With the TravelMate Spin B3, Acer offers a robust 2-in-1 laptop that is mainly targeted for usage in schools. The 11.6-inch device is run by a Pentium Silver N5030 processor. The competitors include devices such as the Lenovo Flex 3 Chrome, the Acer Chromebook Spin 511 R752T, and the Asus BR1100FKA.

Case and Equipment - The TravelMate B3 supports Power Delivery

The robust, black plastic case has a rough surface that offers a good grip to the fingers and is not prone to fingerprints. The short edges of the B3 are protected from bumps by rubber slats. The computer does not show any faulty workmanship. Even though the base unit and lid can be warped slightly, this remains within limits. The battery is built-in. After the bottom has been removed, the insides are easily accessible.

There are three USB connections (2x Type-A, 1x Type-C) that support the USB 3.2 Gen1 standard. The USB-C port supports Power Delivery and DisplayPort via USB-C. So together with the HDMI connection, the Spin B3 has two video output ports. Something that is found rarely in devices such as the TravelMate is the Gigabit Ethernet port. The microSD storage card reader is a slower representative of its kind (measured using our AV PRO SD 128 GB V60 reference storage card).

The 2-in-1 device has two cameras: a webcam (0.9 MP) for video conferencing and a camera (5 MP, HDR, max. 2560 x 1920 pixels) for photos. The latter is located above the keyboard and can be used in tablet mode. While the webcam only offers standard fare, the 5-MP camera produces fairly decent results.

The WLAN transfer rates that we measured under optimal conditions (with no other WLAN devices in close proximity and a short distance between the laptop and the server PC) are basically okay, but they remain behind the capabilities of the WLAN chip used here (Intel Wireless-AC 9560).

Input Devices - The Acer Spin doesn't offer a keyboard illumination

The slightly concave and roughened keys of the unlit chicklet keyboard offer a short stroke and clear pressure point. The key resistance is okay. While typing, the keyboard has a minimal give, but this did not turn out to be any hindrance. Overall, Acer delivers a keyboard here that is suitable for everyday tasks.

The smooth surface of the multi-touch capable ClickPad (~10.5 x 6 cm; ~4.1 x 2.4 in) makes sliding your fingers easy. It also responds to inputs in the corners. The pad has a short stroke and clear pressure point.

The brightness (266.8 cd/m²) and contrast (907:1) of the reflective 11.6-inch touchscreen display (1920 x 1080 pixels) turn out too low. In battery operation, the maximum brightness drops to 238 cd/m². We consider values larger than 300 cd/m² and 1.000:1 as good. We did not notice any PWM flickering.

In the state of delivery, the display offers a decent color reproduction, but the colors deviate slightly from the target. However, this isn't really noticeable. The display is unable to reproduce the AdobeRGB (51%), sRGB (73%), and DCI-P3 (50%) color spaces.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
21 ms ... rise ↗ and fall ↘ combined↗ 11 ms rise
↘ 10 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.4 (minimum) to 240 (maximum) ms. » 35 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (22.6 ms).
       Response Time 50% Grey to 80% Grey
34 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.25 (minimum) to 636 (maximum) ms. » 35 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (35.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19409 (minimum: 5 - maximum: 3846000) Hz was measured.

The IPS panel offers stable viewing angles and can be read from any position. However, you can hardly - and sometimes not at all - read the display outdoors, since the low display brightness and reflective display surfaces make that very difficult.

Performance - Acer uses Gemini Lake in the 2-in-1 laptop

With the TravelMate Spin 3, Acer offers a 2-in-1 device that can handle simple applications from the Internet and office areas.

Test Conditions

The TravelMate does not offer any manufacturer specific power profiles. We use the "Highest Performance" Windows profile for the benchmarks and "Balanced" for the Akkutest battery test.

Processor

A TDP of 6 watts allows passive cooling of the Pentium Silver N5030 CPU (Gemini Lake) used here, which runs at a basic clock speed of 1.1 GHz. Via Turbo, the speed can be increased up to 2.6 GHz (4 cores) and 3.2 GHz (single core).

While it briefly runs through the multi-thread test of the Cinebench R15 benchmark at 2.6 to 2.7 GHz, the clock speed then drops to 1.8 - 1.9 GHz. The single-thread test runs at 2.8 GHz. The speed is the same in mains and battery operation.

We evaluate whether the CPU Turbo is also used constantly by running the multi-thread test of Cinebench R15 in a constant loop for at least 30 minutes. The Turbo speed can only be kept at a high level for a few seconds. After that, it drops to values below 2 GHz.

Overall, the benchmark results are a bit disappointing. The performance of the N5030 remains below its capabilities, as the comparison with the Lenovo IdeaPad 1-14IGL05, which is also cooled passively, shows.

System Performance

The combination of a Pentium Silver and 4 GB of working memory is able to handle simple applications from the office and Internet areas. While the system usually runs smoothly, you should only expect to run few applications and browser windows concurrently, since otherwise things become more sluggish. A part of the computing performance remains unused, because the working memory (DDR4-2400, onboard) only runs in single-channel mode. It is not possible to activate dual-channel mode at a later point. The PCMark results range at the expected level.

Graphics Card

Intel's UHD Graphics 605 GPU represents the lower end of the performance scale. The 3DMark results of the graphics core turn out below average and are some of the worst results that we have measured using this GPU until now. Gaming is not one of the qualities of the hardware used, but simple, casual games and browser games should still run. The integrated decoder takes some load off the processor when reproducing videos, so using streaming services should not present any problems.

Emissions and Power Management - The Acer convertible stays silent and cool

Noise Emissions

Since the TravelMate has neither a fan nor a mechanical drive, it runs silently.

Temperatures

The TravelMate during the stress test
The TravelMate during the stress test

The B3 only heats up to a limited extent overall. Under heavy hardware load during the stress test, we measure higher temperatures in some spots, but in total, the device only gets hand warm. The CPU temperatures give no reason for concern.

In the beginning of the stress test (with Prime95 and Furmark running for at least one hour), the CPU runs at higher speeds. Continuing the test, the speed drops to 1 GHz. The stress test represents an extreme scenario. We use this test to evaluate whether the system remains stable under full load.
