The Miniware TS21 is a soldering iron suitable for both field and home soldering. It is powered via a USB-C connector, making it possible to use a power bank or any power supply that supports PD fast charging. The soldering iron offers adjustable power with a maximum of 100W. All information is clearly displayed on a compact 0.91" OLED screen. The temperature is adjustable within a range of 100–450°C and is precisely controlled by a microprocessor with an intelligent algorithm. The TS21 is equipped with an accelerometer that detects inactivity and automatically lowers the temperature. The Miniware TS21 uses long C210-type tips, which are easy to replace — simply pull them out without the need for screws. Despite not being screw-secured, they hold firmly in place. For added convenience, the soldering iron features an integrated LED light to make soldering easier in dim conditions or hard-to-reach areas. The TS21 body is made of aluminum.
