Nearly 20 Hours Battery Life — The X1 Carbon Standard
The refurbished ThinkPad X1 Carbon 6th Gen was awarded MobileMark 2014 battery life of up to 19.3 hours — one of the highest ratings ever recorded for a business ultrabook. In real-world use, the 57Wh battery comfortably delivers two full working days between charges for light to moderate users. Rapid Charge brings the battery to 80% in approximately one hour. This extraordinary battery life, combined with a starting weight of 1.13kg, makes the X1 Carbon 6th Gen one of the best travel laptops ever produced.
Carbon Fibre Flagship Build
Lenovo built the X1 Carbon 6th Gen to EPEAT Gold certification and MIL-STD-810G military durability standards. The display cover uses a carbon fibre reinforced plastic and GFRP hybrid for maximum rigidity at minimal weight. The bottom chassis uses magnesium alloy. At just 15.95mm thin and starting from 1.13kg, it is lighter than many 13-inch ultrabooks despite its 14-inch FHD WVA display offering 170° viewing angles and 300 nits brightness. The 6-row spill-resistant keyboard with LED backlight and the ThinkPad buttonless glass trackpad deliver a premium input experience.
Thunderbolt 3 and Dual USB-C
Both USB-C ports support Thunderbolt 3 — enabling 40Gbps data transfer, 4K or 5K display output, USB Power Delivery charging and single-cable ThinkPad docking. HDMI 1.4b provides direct monitor output. The side docking connector supports Lenovo ThinkPad mechanical docking stations for multi-monitor office setups. Two USB-A ports (one Always On) and a microSD card reader cover everyday peripheral needs. Three independent displays are supported simultaneously.
