With the surge in one-person businesses, what are the suitable IT devices for office equipment and gear that are difficult to manage meticulously? We introduce customized 'IT devices' for aspiring entrepreneurs that reduce costs and increase work efficiency.

Brother International Korea's 'Infinite Refill Inkjet Multifunction Printer'
For office equipment such as printers and multifunction devices, which must be used for over five years once purchased, cost-effectiveness and durability are crucial. Just when you think you’ve used a fair amount of ink, the black text inevitably starts losing its color. "Continuous refill inkjet" is a method of refilling ink without replacing cartridges. It reduces the risk of getting ink on your hands and saves on maintenance costs by allowing you to use genuine refill ink in the 10,000 won range.


Sony Korea's mobile projector 'MP-CL1'
With a thickness of 13mm and a weight of 210g, a 305cm (120-inch) screen can be implemented in a space of only about 3.45m. The 'autofocus' function, which projects an image directly using a laser beam and automatically adjusts the focus based on distance, forms a focus on all surfaces, even on curved walls. It can be used for about two hours on a 100% charge, and can also be charged by connecting it to a smartphone when used outdoors.


Logitech's multi-device wireless keyboard 'K375s'
This full-size keyboard comes with a multi-purpose rubber stand for mobile devices, allowing you to type on PCs, smartphones, and tablets. You can handle computer typing, tablet emails, and smartphone messaging with a single keyboard. You can switch between three devices with a single button. It is compatible with both Android and iOS. It offers a wireless range of 10 meters. Additionally, you can set a wireless password between the keyboard and the computer.


LG Electronics' laptop 'Gram 14'
In 2017, it was recognized by the Guinness World Records as the lightest product. The battery life is approximately 12 hours. The recently released LG 'All Day' Gram can be used for up to 24, 23, and 22 hours, respectively, depending on the 13.3-inch, 14-inch, and 15.6-inch sizes.


Neotizen 'Fogring Humidifier'
Offices are often dry due to the use of air conditioners or heaters. This humidifier, shaped like a small donut with a diameter of 5 cm, emits steam from a hole in the center when floated on water. Ultrasonic waves strike the water 120,000 times per second to create steam. Additionally, the densely perforated vibrator itself acts as a filter, eliminating the need for filter replacement.
