A Phone Thermal Camera Finds What You Can't See: Check USB-C Fits Your iPhone or Android First, Then Trace Leaks, Heat Loss and Hot Breakers

This is a tool for problems you can feel but not see: a wall that is cold near the floor, a breaker that trips warm, a pipe somewhere behind the tile. The P1 camera turns your phone into the display: it plugs in over USB-C and reads as an infrared thermal imager, and the listing states a 320×240 sensor — the number that decides how much detail you actually get on small hot spots — plus a 600℃ top of range, 25 Hz live refresh and 15× digital zoom. What it is used for in practice: walk a room during heating season and cold seams on the wall show missing insulation or a thermal bridge; after rain or under a bathroom floor, a wet patch holds temperature differently than dry material and traces the leak path; open the electrical panel (cover off, per safety rules) and an abnormally warm connection on a breaker or a wire is a finding, not a guess; check radiators and underfloor loops for sections that are not circulating. The fitment question comes first: the listing says it works with iPhone and Android, but the plug is USB-C — before ordering, confirm it fits your exact phone model, and what adapter is needed if your iPhone still has a Lightning port. Second: thermal cameras read surface temperature, not depth — a warm ceiling shows the path, not the source. Third, the app does the work, so ask whether it is free, whether extra analysis features cost money, and whether the 320×240 figure is the native sensor or an interpolated one. Point it at the right problem and it pays for itself the first time it finds a leak before the ceiling does. 1257 sold with a 98.0% positive rating.
