Car Battery Capacity Tester: Dual USB, Suitable for Lead-acid and Lithium Batteries

Dive into the world of power efficiency with our high-performance models: Model A and Model B.
Model A – a 48V power/voltage model
Model B – an 8-48V voltage universal model

Feature rundown:

1. Our product is comprehensive in its functionality. It not only exhibits the battery voltage and battery power but also allows direct plugging into the phone or other 5V equipment for charging.
2. From outdoor power sources to mobile power and instrumentals, this product fits in seamlessly. It brings additional battery power voltage display and USB charging features for phones and other devices.
3. The use of a synchronous rectification step-down chip scheme ensures lowered heat alongside fostering energy conservation and environmental friendliness.
4. The compactness of this product is a boon for space optimization and cost-cutting.

Specifications:
Input voltage 8-48 (V)
Output voltage 5 (V)
Output current 2000 (mA)
Output interface: USB

Model Specifics:
For the 48V power / voltage model, it cycles display every 10 seconds, showing voltage, then power percentage. A flashing undervoltage warning appears when the power drops below 30%. For the 8-48V voltage universal model, it displays digital voltage and can host universal batteries in the range of 8V-48V.

Keep in mind:
It’s vital for the power display of these models to match the battery to correctly report the percentage of power, as it’s deduced from the voltage. The combined current of the two USB ports equals 2A. With large-screen mobile phones demanding extensive charging current, we advise using a single USB plug for charging to prevent potential damages.
