 Reliability and portability are the main goals of the expert book lineup by ASUS. There are many series in this business line starting from the affordable B1 and going up to the ultra premium B9. The B5 we have with us today is the most balanced choice for providing a cost effective price point and premium quality. Plus, this is the flip modification so you can rotate the screen as you like. It is built like a tank but you wouldn't be able to see that looking at its thin body nor will you find it in the spec sheet. Stay with us to see how that's possible. Let's start with portability. This 13 inch laptop weighs just above 1 kilo and it's 16.9 mm thin. Lifting the lid also lifts the backside at the notebook providing both better airflow to the cooling system and better ergonomics when typing on the backlit keyboard. The keys are big so there's no space left for the numpad but we have the cool LED illuminated keypad hidden in the trackpad called ASUS number pad. It's a bit small for our taste but it's still good. As we already said, the screen can be rotated in 360 degrees and you shouldn't worry about it because it is held by thick stainless steel hinges with large screws. The whole body is made of aluminum and magnesium and is further strengthened by a honeycomb construction on the inside. We also see rubber dampers that protect the mainboard from shocks and spill resistant design for the keyboard. With all these it's not hard for the B5 Flip to get the A10H military certification. Even the ports have additional protection with stainless steel brackets. The B5 Flip is equipped with two Thunderbolt 4 ports supporting power delivery, micro HDMI to Ethernet, Kensington lock slot, HDMI 2.0B, one full size 10 gigabit USB port, audio jack and a fingerprint reader hidden in the power button. So you can connect up to three 4K external displays. However, many business users often need to work on the go and the integrated screen allows for comfortable operation out of the office. There are three display options, two IPS and an FHD OLED panel with 400 nits of brightness and 100% coverage of the ultra-wide DCI-P3 color gamut. This is our choice for the review as we really like the deep blacks and the vivid colors. The OLED panel also has lower harmful blue light levels compared to regular LCDs. However, if you're going to do color sensitive work, go for one of the IPS variants since they'll have better color accuracy. Also check out our display profiles from the link in the description below the video. There are two battery variants with a capacity of 33 watt hours or 66 watt hours. The OLED variant always comes with a 66 watt hour unit which lasts for 12 hours and 27 minutes of web browsing or 10 hours and 50 minutes of video playback. These are pretty good results and should get you through a whole day of work without needing a charger. Only 2 per 100 people watching this video are subscribers.

We've conducted the tests with a Core i5-1135G7 processor, but you could also configure your B5 flip with an i3 or an i7. On the GPU front, you rely on integrated graphics, powerful enough for most types of work. The notebook comes with a simple cooling solution as there's only one heat pipe, one fan and one heat spreader. In the stress test, the Core i5-1135G7 gets pushed past its 28 watt power limit, going as high as 40 watts and boosting to 3.4 GHz in the first seconds of the test. After that the clock speeds and temps lower, maintaining a consistent 2.51 GHz at 80°C. Comfort is excellent as the metal chassis is pretty well isolated, giving us an outside temperature of only 38°C, while the fan works quietly and activates only under extreme stress. Despite its portable body, the expert book B5 Flip is one of the best 13 inch devices in terms of upgradeability. We're pleasantly surprised that the storage isn't soldered. You even get not one, but two NVMe slots with RAID 0 or RAID 1 support. Also, there is soldered memory, but ASUS has found space for an additional RAM slot for future upgrades. And upgrading the laptop is a fairly easy task. We have a detailed teardown video that shows a step-by-step process, which you can find in the description. On top of all that, you still get the usual perks of the expert book lineup, like the two-way AI noise cancelling technology that eliminates ambient noise in your meetings, the ultra-fast Wi-Fi 6 connection, and the webcam shield. Speaking of meetings, here's a very cool feature, one of our favorites. This little light automatically starts glowing when you're busy on a conference call, so your colleagues will know not to bug you. Also, while ASUS says that the pen is optional, we found one in all configurations that we checked out. Keep in mind the three-year international warranty, so you're covered wherever you are in the world. The laptop is also Windows 11 ready, thanks to the TPM 2.0 module on board. All in all, ASUS expert book B5 Flip B5302 is one of the leading 13-inch business laptops, providing excellent reliability, high portability, and ample upgradeability. That's why it wasn't a hard decision to award this notebook with our editor's choice medal. So check out our in-depth review on laptopmedia.com, because we have a lot more to share with you.
