USB 5V 2.1A Car Voltmeter Voltage Meter Panel 12V 24V 36V 48V 72V Auto Li-ion Lead Acid LED Display
Lead-acid 12V 24V 36V 48V 72V universal ( automatic identification )
Static Input Current: 5-25mA,the lower the battery voltage,the smaller the current.
USB Output 5V/2A(max), two USB port total is 2A(a USB setting for Apple recognition, a USB setting for Android recognition)
USB step down efficiency is up to 96% (because of the synchronous rectification circuit, the buck conversion efficiency is high and the heat is low.
8 segment power resolution: 10% 25% 40% 50% 60% 75% 90% 100%
The accuracy of the voltmeter is about 2%
Working Temperature: -10~+65?
Working Humidity: 10-80% (no condensation)
Opening Size: approx. 45*26*18mm
