The Sunmi L2k is available in two variants, which only differ by using an integrated Zebra barcode scanner with support for 1D barcodes and 2D barcodes. Especially because of the use in the transport and logistics field as main work area, the variant with integrated barcode scanner is rather a standard variant.
Both variants include a lithium polymer battery with 5000mAh, which is even changeable as a real feature. In addition to this main battery, the Sunmi L2k also has a second, internal battery that keeps the device running in the event of a battery change. This means that a battery change during operation is possible without a device's shut down.
Sunmi extends the existing Scan, Volume and Power buttons on the L2k with a full numeric keypad with a second keyboard layer and function keys. For example, quantities can be entered in the case of inventory or weight data for order picking directly on the device without using the on-screen keyboard.
The housing of the L2k is certified with protection class IP65 and supports a temperature range in operation of -20°c to up to 55°c as well as falls from up to 1.5m height.
For wired data transfer and charging of the device, a USB-C connection is available on the device.
Wireless data transmissions are also, Sunmi typical, available in a variety of ways: Wireless LAN in version 802.11 a/b/g/n with dual band function for 2.4GHz and 5GHz is integrated as well as Bluetooth in version 4.2.
In addition, a 4G module for mobile data transmission is available with a SIM card slot. The use of this SIM card for telephony is still not supported by Sunmi.
The NFC reading function for RFID chips is of course also still integrated.
Other modules and functions such as speakers with microphone, a 13 megapixel camera with autofocus function on the back, a 2 megapixel front camera and an integrated GPS module are of course still standard equipment.
