With this detector you can easily check out poor quality cables or chargers, and find out the reason why your phone charges slowly. - Features 1: Dual color display for both Voltage and Current simultaneously. Voltage is in red and current in blue, it is easy for you to distinguish and you can read both data at the same time with this USB monitor. - Features 2: There are 7 different display modes for this USB monitor to choose. Modes: VA(Voltage and Ampere), C(Capacity), P(Power), VA+C, VA+P, C+P, VA+C+P - Feature 3: This multimeter has over voltage and under voltage alarm, over-current, and short circuit alarm protection. - Feature 4: Two output ports make it possible to charge two devices at the same time with one charger. But please be noted: if you connect 2 devices to the detector, the voltage is of both output (parallel circuit voltage is equal), and the current is the sum of the two ports. - ›See more product details ## Images ![Youtumall USB Meter Multimeter Detector Battery Tester Dual Display Voltmeter Ammeter for Phone Battery pack - Image 1](https://images-na.ssl-images-amazon.com/images/I/61TUIZoXSKL.jpg) ![Youtumall USB Meter Multimeter Detector Battery Tester Dual Display Voltmeter Ammeter for Phone Battery pack - Image 2](https://images-na.ssl-images-amazon.com/images/I/61-gj%2B88cyL.jpg) ![Youtumall USB Meter Multimeter Detector Battery Tester Dual Display Voltmeter Ammeter for Phone Battery pack - Image 3](https://images-na.ssl-images-amazon.com/images/I/51RPvgj%2B3cL.jpg) ![Youtumall USB Meter Multimeter Detector Battery Tester Dual Display Voltmeter Ammeter for Phone Battery pack - Image 4](https://images-na.ssl-images-amazon.com/images/I/51T4KJqcPkL.jpg) ![Youtumall USB Meter Multimeter Detector Battery Tester Dual Display Voltmeter Ammeter for Phone Battery pack - Image 5](https://images-na.ssl-images-amazon.com/images/I/51thbSmLoyL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/55705728-youtumall-usb-meter-multimeter-detector-battery-tester-dual-display-voltmeter](https://www.desertcart.co.th/products/55705728-youtumall-usb-meter-multimeter-detector-battery-tester-dual-display-voltmeter) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
