Panasonic CF-31 MK1 13.3" Fully Rugged Laptop, Intel Core i5-520M, 8GB RAM, 256GB SSD, Restored

While the Toughbook 30 met the MIL-STD-810F durability standard, the CF-31 is made of tougher stuff, and is designed to meet specifications for ingress protection (IP-65) and durability (MIL-STD-810G). That means, among other things, it can withstand operating temperatures from -20 to 140 degrees Fahrenheit (-40 to 160 degrees when turned off), and altitudes of up to 15,000 feet. It can survive 31 minutes of 70-mph wind and 5.8 inches per hour of rain blown at it, and 26 drops from 72 inches while turned off (36 inches while turned on and open). It can also withstand up to 310 pounds of pressure on its lid. And while this fully rugged notebook looks the same as its predecessor on the outside, inside this Intel Core machine boasts almost double the performance and increased protection without sacrificing battery life.
