DC 12V Red Display Blue Display LED Digital Lead Acid Tester Voltmeter Mini Battery Tester Panel With Dual USB Outputs 5V2A For Car Motorcycles

1. Static input current: 5-25mA, the lower the battery voltage, the smaller the current. 2. USB output: 5V/2A (USB settings for Apple recognition, settings for Android recognition) 3. The voltage reduction efficiency of USB is as high as 96% (due to the use of synchronous rectification circuit, the voltage reduction conversion efficiency is high and the heat generation is low). 4. 8-stage power resolution: 10% 25% 40% 50% 60% 75% 90% 100% 5. The accuracy of the voltmeter is about 2% 6. Working temperature: -10~+65 ° C 7. Working humidity: 10-80% (without condensation) 8. Opening size: 45 × 26 × 18mm 9. 12V lead-acid battery
