LED Digital Display Voltmeter Voltage Meter Volt Tester Dual USB 5V 2A for DC 12V Cars Motorcycles Vehicles Battery Capacity(Blue)

Ammeters1, you can display the battery voltage, battery power, you can also directly into the phone or other 5V equipment charging.2, This product is suitable for all kinds of outdoor power, mobile power, instrumentation and other equipment additional battery power voltage display and additional USB to charge the phone and other functions.3, this product uses rectification step-down chip scheme, low heat, energy saving and environmental protection.4. This product is compact in structure, making full use of space and reducing costs.Product parameters 1. Static input current: 5-25mA, the lower the battery voltage, the smaller the current. 2, USB output: 5V/2A (a USB setting for recognition, a setting for Android recognition) 3. USB efficiency is up to 96% (because of the rectification circuit, the conversion efficiency is high and the heat is low. 4.8 segment power resolution: 10% 25% 40% 50% 60% 75% 90% 5. The accuracy of the voltmeter is about 2%6 working temperature: -10 ~ +65 ° C 7. Working humidity: 10~80% (no condensation) 8. Opening size: 45 × 26 × 18mmThe latest improvement: increase the undervoltage warning function, 12.5% light flashes when the last battery charge is left in the battery!It is best to stop using it and charge it!
