As a tech reviewer who frequently tests a wide array of smartphones, Ive learned the importance of monitoring device temperatures during usage. One of the most reliable methods for assessing how hot a device can getespecially during prolonged gaming sessionsis the use of a thermal camera. This year, I've noticed that many new smartphones, such as the Nubia Z70 Ultra, are reaching impressively high temperatures, with readings soaring up to 59 degrees Celsius.

While traditional thermal cameras are sophisticated tools, advancements in technology have led to the creation of USB-C dongles that serve similar purposes at a more accessible price point. In my recent testing, I've been using the Thermal Master's P2 for over a month, and I can confidently say that this compact device has proven itself to be reliable and efficient.

Available for around $199 on both Amazon and Thermal Master's official website, the P2 is quite reasonably priced considering the quality it offers. Weighing in at just 10 grams, this tiny thermal camera comes in a lightweight plastic casing, complete with a built-in carabiner. This practical feature allows users to easily attach it to a key ring or bag, making it incredibly portable.

Connecting the P2 to various smartphones, including the Vivo X200 Pro, Honor Magic 7 Pro, Find X8 Ultra, and Xiaomi 14, was seamless thanks to its USB-C compatibility. Its compact design means it can be taken anywhere, making it a useful tool for daily tasks. The P2 features a native resolution of 256x192 pixels but utilizes a custom algorithm to upscale this to 512x384, ensuring that images are notably clear and detailed. This is particularly beneficial when identifying hot spots on smartphones, laptops, and even tablets like my iPad Pro M4.

The P2 is impressive in its temperature range capabilities, able to measure temperatures from -4 degrees to an astonishing 1,112 degrees Fahrenheit. It also features a 15x zoom, which allows for detailed analysis of specific areas. An exciting aspect of the P2 is its versatility with color palettes; users can choose from 12 different options to tailor the thermal images to their preferences. This feature enhances the user experience, allowing for a clear differentiation of temperature zones within an image.

In addition to capturing images, the Thermal Master P2 allows for video recording. Although the video resolution might not compete with higher-end cameras, its sufficient for identifying thermal discrepancies without difficulty. With a minimal power draw of just 0.3 watts, its energy-efficient and convenient for extended use.

Overall, the standout feature of the Thermal Master P2 is its portability and compact size. In contrast to many larger thermal cameras I have used in the past, the P2 delivers comparable performance in a significantly smaller package. Its a fantastic tool for various applications, whether you need to monitor heat issues in a power line, detect leaks in your home, or simply gauge how hot your devices are getting during intensive usage.

If youre in the market for a thermal camera that you can take anywhere, I highly recommend the Thermal Master P2.
