Description
Product Description
USB 5V 2A Car Voltmeter Voltage Meter Panel 12V 4S Lithium Battery Capacity Indicator Power Tester Li-ion Lead Acid LED Display
Features: 1. This product has complete functions, which can display battery voltage and battery level, and can also be directly plugged into mobile phones or other 5V devices to charge 2. This product is suitable for all kinds of outdoor power supplies, mobile power supplies, instruments and other equipment with additional battery power and voltage display and additional USB charging for mobile phones and other functions 3. This product adopts synchronous rectification and step-down chip solution, which has very little heat generation, energy saving and environmental protection. 4. This product has a compact structure, makes full use of space and reduces costs
Specifications: 1. Static input current: 5-25MA, the lower the battery voltage, the smaller the current. 2, USB output: 5V/2A (one USB for Apple identification, one for Android identification) 3. The USB step-down efficiency is up to 96% (because the synchronous rectifier circuit is used, the step-down conversion efficiency is super high and the heat generation is low 4.8 segment 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% (no condensation) 8. Hole size: 45×26×18MM 9. Color display: red display/blue display Package Included: 1pcs * Dual USB Port LED Digital Voltmeter
