Timing: YES 7. The over-current protection: Yes 8. Packaging: opp bag 9. Package list: 1*Usb voltmeter detector The use Power display current and voltage, a single short press the button for about 0.5 seconds to view the capacity and timing screens. When displayed on the screen press capacity around button for two seconds to clear the stored data. When the display screen at the timing of the long press button for two seconds will be flashing numbers, and then press a single button for 0.5 seconds each time the cumulative 0.5 hours per block long press 2 seconds to confirm the save. Battery capacity test: Use TP4056 and other linear charging circuit through this capacity to the table completely empty battery is fully charged to full capacity reading on the battery capacity, the use of this method can be measured charge capacity of the phone, the phone can even calculate theharging efficiency Mobile measuring power output capacity and efficiency: The first machine connected mobile power, mobile power turn on, long press the button until the volume of data to zero, into the phone and more mobile power charging until no power automatically shut down. Next displayed when you turn the unit capacity is the mobile power output mAH. MicroUSB line quality measurement: female plug mobile phones and other devices, first use the native male plug 5V chargers, remember that voltage, then MicroUSB cable into the bore in mind that the machine MicroUSB charger voltage from 5V, the smaller the gap voltage MicroUSB cable quality is better ## Features - MEASUING VOLTAGE AND CURRENT: USB male plug 5V chargers, mobile phones and other equipment female insert, read current and voltage directly - Multifunctions: Display current and voltage; Battery capacity test; Mobile measuring power output capacity and efficiency; MicroUSB line quality measurement - The phone is fully charged to automatically turn off the output. No load 20 seconds automatically shut down output - Power-down save function: USB and MicroUSB port male double take power, can be detected MicroUSB line quality; Current sampling 50 milliohms, smaller loss; With precision current calibration, higher current accuracy - This voltage meter displays the voltage and current data mAH, timing, easy viewing ## Images ![Electrical USB Current Voltmeter Tester USB Battery Capacity Tester with Mobile Phone Charging Test Meter Detector - Image 1](https://images-na.ssl-images-amazon.com/images/I/41g4GAcjQnL.jpg) ![Electrical USB Current Voltmeter Tester USB Battery Capacity Tester with Mobile Phone Charging Test Meter Detector - Image 2](https://images-na.ssl-images-amazon.com/images/I/51FkbgNh1kL.jpg) ![Electrical USB Current Voltmeter Tester USB Battery Capacity Tester with Mobile Phone Charging Test Meter Detector - Image 3](https://images-na.ssl-images-amazon.com/images/I/41BNnaIdNzL.jpg) ![Electrical USB Current Voltmeter Tester USB Battery Capacity Tester with Mobile Phone Charging Test Meter Detector - Image 4](https://images-na.ssl-images-amazon.com/images/I/516kt-ZTp6L.jpg) ![Electrical USB Current Voltmeter Tester USB Battery Capacity Tester with Mobile Phone Charging Test Meter Detector - Image 5](https://images-na.ssl-images-amazon.com/images/I/51DZXktr6iL.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.uk/products/61591147-electrical-usb-current-voltmeter-tester-usb-battery-capacity-tester-mobile](https://www.desertcart.co.uk/products/61591147-electrical-usb-current-voltmeter-tester-usb-battery-capacity-tester-mobile) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
