Serplex Digital USB Power Meter & Type-C Cable Tester (600W PD 3.1)

<p>You own six USB-C cables and three chargers, and you have no idea which combination is actually fast-charging your phone and which is quietly trickling 5W. Plug this inline tester between charger and cable and it shows live voltage, current, wattage and the negotiated PD protocol — so you can find the dud cable in about thirty seconds instead of guessing.</p><p>It is slept-on because most people buy another charger instead of testing the cable they already have. Handles 4.5-50V, 0-12A and up to 600W PD 3.1, and holds <strong>4.7 ★ across 70 ratings</strong> on Amazon.in.</p>
