Product description:

1. This product is fully functional, that is, it can display the battery voltage, battery power, but also can be directly plugged into the mobile phone or other 5V devices charging
2. This product is suitable for all kinds of outdoor power supply, mobile power, instruments and other equipment additional battery power voltage display and additional USB to charge mobile phones and other functions
3. This product adopts synchronous rectifier buck chip solution, generating very little heat, energy saving and environmental protection
4. This product has a compact structure, making full use of space and reducing costs.

Parameters:

• Static input current: 5-25MA, the lower the battery voltage, the lower the current.
