Description

LED Digital Display Voltmeter Voltage Meter Volt Tester Dual USB 4S Lithium Iron Phosphate Lead Acid Tester Battery capacity

Description:

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 supply, mobile power supply, instrumentation 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

Parameter

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
