Verdict
The TC001 Plus is the middle model in TOPDON’s plug-in thermal range. It keeps the 256×192 detector, TISR upscaling to 512×384, 25 Hz refresh and the wide measurement range of the family, and puts them on a USB-C connector so it works with recent Android phones, tablets and USB-C iPhones. The version most buyers will find on Amazon US is the TC001 (Android only) or the newer TC001 Max, which adds a visible-light lens; the Plus is not currently listed separately. If you have a USB-C phone and want a thermal-only camera without paying for the dual-lens Max, the Plus is the right specification to search for. If you need visible-light fusion for reports, buy the Max.

Detector and Measurement
The 256×192 detector (49,152 pixels) is the reason the TC001 family is popular: it has more than twice the pixels of the 160×120 detectors in the FLIR ONE Pro and E5 Pro. The TC001 Max listing states a 25 Hz refresh rate, thermal sensitivity of 40 mK or better, a measurement range of -20 °C to 550 °C and accuracy of ±2 °C or ±2%. TOPDON documents the same detector class for the Plus. In practice that means a consumer unit or a PCB is readable at a working distance, and hot connections show up as clear points rather than a blur. Our guide to comparing thermal camera resolution puts these detector sizes in context.
App and Analysis
TOPDON’s app provides point, line and area measurement with up to three of each, live high, low and average temperature, a temperature-over-time graph, multiple palettes, image rotation and photo and video capture. The listings for the family describe a fusion mode that blends the thermal image with the phone camera; on the Max this uses the built-in visible lens, on the TC001 and Plus it uses the phone’s own camera, which requires alignment and is less convenient. Emissivity is adjustable, which is necessary for measuring on metal; see setting emissivity.
Power and Portability
The whole family has no internal battery and draws about 0.35 W from the phone, with the listings quoting four to seven hours of use from a typical phone battery. The body is pocket-sized and around 30 g. The extension cable supplied with the TC001 lets the camera be placed away from the phone, which owners use for looking into panels and behind equipment. The Plus and Max are designed to plug directly into the phone port and, according to the Max listing, work without removing most cases. Because the camera relies on the phone’s USB power and data implementation, the usual advice applies: check the compatibility list for your exact phone model before buying, and expect tablets and older phones with weak OTG support to be the exceptions owners report.
Strengths
- 256×192 native detector at a plug-in camera price.
- USB-C compatibility with current Android and iOS devices.
- No battery to charge; long runtime from the phone.
- Wide measurement range suitable for electrical and automotive work.
Limitations
- Not currently listed separately on Amazon US; the TC001 or TC001 Max are the listed models.
- No visible-light lens; fusion depends on the phone camera.
- Phone-dependent: the phone is occupied during use and supplies the power.
How It Compares
The TC001 is the Android-only original with the same detector and a lower price. The TC001 Max adds the dual lens for cleaner fusion images and is the current flagship of the family. The TC002C is the USB-C model TOPDON positions for iPhone and Android alike. Against FLIR, the FLIR ONE Pro has fewer pixels and its own battery but offers MSX and FLIR’s app. See how to choose a smartphone thermal camera.
