USB Soldering Iron Set Multi-Purpose USB Soldering Iron Portable Digital Soldering Pen Temperature Control Range of 200–500°C

The set includes a soldering iron, a tip (not C210, with one insulator), an A to C USB cable, one solder wick, 20g of solder (doesn't melt well at 350 degrees), two tweezers, a plastic solder holder (with sponge), a thin metal stand, and a manual (Korean included). It all comes in a plastic case. The soldering iron doesn't have an automatic shut-off or sleep mode; it stays on until you turn it off. You can turn it on/off by pressing and holding the power button, and quickly double-pressing it when on switches between Fahrenheit and Celsius. To adjust the temperature, press + or - once for a 1-degree change, or hold for more rapid changes. When you set a temperature, it quickly heats up to that temperature using about 5V 2.1A, then settles to the appropriate current (A) for the set temperature. It uses about 4-5W at 300 degrees. You can see the temperature on the display, but the actual iron heats up faster than the display shows (about 10 seconds). Although an A to C cable is provided, the iron has a pull-down resistor, so you can use a C to C USB cable without issues (no explosions or high voltage). Most importantly, the temperature accuracy is good. When tested with calibrated irons using solder that melts at 220 degrees and works smoothly at 260 degrees, this iron also works smoothly at 260 degrees. It can even handle 0.75SQ wires at 300-320 degrees.
