In this video, I check out the Topdon TC004 Mini thermal imaging camera. It’s a compact, budget-friendly option. I’ve used their Tornado 30000 battery charger before and love it. I have also tested other thermal imagers on the boat to spot hot spots in wiring, monitor the diesel engine, and more. They are super handy for RV and marine troubleshooting.
The TC004 mini version is much smaller and lighter than most handheld thermal imagers. However, it has only a 128×128 base resolution but is boosted to greater effective detail via their TISR (Thermal Image Super Resolution) technology.
It includes multiple color palettes (iron, rainbow, hot red, white hot, etc.), a 25Hz refresh rate for smooth viewing, photo capture (no video), USB-C charging and data transfer, 15-hour battery life, a tripod mount, and a drop-resistant build.
Menus let you tweak emissivity for different surfaces, set high/low temp alarms (with auto-capture), switch F/C/Kelvin, and more. The screen is a bit dim in bright daylight and small for my older eyes, but not too bad indoors.
I tested it on our RV fridge boiler, water heater pipes, power center, stove flames (hit 991 F in high mode), charging toothbrush, and even the shore power cord. It’s great for quickly spotting overheating wiring or components before issues arise.
Pros: Super portable, long battery, solid build, affordable price, and plenty capable for occasional RV, boat, or home use.
Cons: Lower native resolution than pricier models (images can look a tad over-sharpened), and screen readability could be better in sunlight.
