SDG #344 TS-210 USB-C JBC Style C210 Soldering Iron PD3.0 QC3.0

The TS-210 is an unbranded, sub-£20 portable soldering iron built around JBC C210 style cartridges, and it aims squarely at the same buyer as the Miniware USB irons. Power input is unusually flexible for the money: USB-C with power delivery 2.0/3.0, PPS and Quick Charge 2/3 negotiation, plus a supplied barrel jack adapter for anyone running a bench DC supply. In testing it pulled around 41 W on startup and roughly 50 W continuously with a genuine JBC cartridge, which is enough to reach 250 °C almost instantly.

The teardown shows a sensibly simple design: a CH549 microcontroller handling PD negotiation, OLED driving and control, a P-channel MOSFET driving the heater via an NPN level shifter, an op-amp for thermocouple sensing, a current sense chip, and no electrolytic capacitors to age out. Two screws and a sliding barrel get you inside, so repairs are realistic. The likeliest long-term wear point is the cartridge contacts going high resistance.

Accuracy out of the box was poor, reading close to 390 °C at a 345 °C setpoint, but unlike some budget irons this one offers a genuine four point calibration routine. After walking through the 200/300/400 °C points the reading settled within a couple of degrees of setpoint, which turns a suspect iron into a usable one. Sleep and standby behaviour also works well, dropping to 150 °C after 35 seconds and recovering in around two seconds via the motion sensor.

The main gripe is the cheap joystick: left/right adjustment is fine, but the centre press often binds unless hit dead on. Configurable 5 °C steps, adjustable OLED brightness and a flip-display option for left-handed users are welcome touches. For a beginner wanting C210 tip performance on a tight budget, it is a strong value proposition provided you calibrate it first.
