Asus ExpertBook B3 Flip in review: 2-in-1 laptop with digital stylus and LTE modem

Asus has chosen a matte, black case and a mix of materials, with metal for the back of the lid and plastic for the base unit. The clearances are even and there are no sharp edges. The base unit and the lid can be twisted slightly too easily. The battery is fixed and there is no such thing as a maintenance flap.

The convertible has two USB-C ports (1x USB 3.2 Gen 1, 1x USB 2.0). On top of that, it has two USB-C ports (Thunderbolt 4) supporting PowerDelivery and DisplayPort per USB-C. So all in all, the B3 has three video outputs including the dedicated HDMI port. The microSD memory card reader is one of the slower models (reference card: AV PRO microSD 128 GB V60).

The 2-in-1 device has two cameras on board: one webcam (0,9 MP) for video conferences and one camera (13 MP) for taking photos. The latter is placed above the keyboard and can be used in tablet mode. The webcam is a standard-quality model, but the 13-MP camera shows solid results.

The Wi-Fi chip (MediaTek MT7921) supports the standards 802.11a/b/g/n/ac/ax. Under ideal circumstances (no other Wi-Fi devices in proximity, small distance between laptop and server) the transfer rates are okay, but can't match today's devices and their options.Intel's AX chips show significantly better results. Wireless connections can also be set up via the LTE network, thanks to a compatible modem (Fibocom L850-GL). The memory card reader and SIM card reader (nanoSIM) share a tray.
