LituFoto's F18, in silver, is slightly larger than their F12 light and adds a USB power bank function. The light features an all-aluminum housing with a built-in battery, and it is ultra-slim and about the size of a smartphone. In this robust and portable design, it provides 3200K and 5600K dual-color temperature, brightness dimming, and a color OLED screen on the rear that confirms all these settings. In addition to a micro-USB charging port, it also provides a USB Type-C power bank port, which allows you to charge your smartphone and other mobile devices.
