The unit features a high-impact housing and an integrated pocket clip for field portability. Its alternating display cycles between volts and amps, giving technicians a quick read on port performance without requiring a full bench setup. Electricians and low-voltage installers use this tool to verify wiring polarity, assess solar USB charger output, and diagnose charging circuit issues. A 1-year manufacturer warranty is included.\u003c\/p\u003e\n\u003cp\u003eThis tester is suited for residential and light commercial electrical work where USB power verification is part of the service call. It is commonly used when installing or inspecting USB outlet receptacles, vehicle charging ports, solar panel charging accessories, and portable power stations. The device is compact enough to carry in a tool pouch and provides an immediate pass-or-fail read on USB port integrity without additional test leads or setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlternating display shows both voltage and current draw in sequence for fast diagnostics\u003c\/li\u003e\n  \u003cli\u003eHigh-impact housing provides durability in field conditions\u003c\/li\u003e\n  \u003cli\u003ePocket clip included for hands-free portability on the job\u003c\/li\u003e\n  \u003cli\u003eTests wiring polarity to confirm proper USB port installation\u003c\/li\u003e\n  \u003cli\u003eCompatible with solar USB charger output testing\u003c\/li\u003e\n  \u003cli\u003e1-year manufacturer warranty included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard USB ports, USB chargers, and USB cables in residential, commercial, and mobile applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis is a diagnostic tool, not a hardwired component — no installation is required.
