The RELIFE TB-09 SE Charging Port Tester is built for technicians who need fast, no-disassembly diagnosis of charging port faults. With dual Type-C and Lightning (8-Pin) plugs, you test both Android and iOS devices on your repair bench without swapping tools. The unit reads diode characteristic values automatically and shows the result on its display — a 0.00 reading flags a short circuit, OL means an open circuit, and a red value points to abnormal PN junction behavior. It's a quick-check tool for dead phone diagnostics, charging issue troubleshooting, and confirming whether a fault sits in the port or deeper in the board before you commit to a jumper or IC change.
