Product Details
This is an advanced DC charging and discharging integrated module. It offers a 5V normally open output that remains stable regardless of load connection, with a maximum load current of 2A. It has 4 levels of charge/discharge electricity indication and button-controlled output. The built-in power management circuit can boost a lithium battery to 5V and supports simultaneous charging and discharging. It also comes with battery protection, suitable for batteries without a protective board. This module is great for car charging retrofit, powering driving recorders, DIY mobile power banks, and portable charging for phones and laptops. Note that the KEY function is disabled in charging mode. In discharging mode, a short press enables output and lights up the indicator, while a 10-second long press disables it. The indicator turns off after 35 seconds of inactivity. When charging and discharging simultaneously, balance input and output to extend the module's lifespan. Features include 4 levels of charge/discharge indication, button-controlled output, and a built-in power management circuit. Applications are car charging retrofit, driving recorder power supply, DIY mobile power bank, and portable phone/laptop charging.

Shipping List: 1 x 5V/2A DC-DC Charge Discharge Integrated Module.
Using this module is easy. First, make sure you understand the wiring instructions for charge, discharge, or both. When using it for charging, connect it correctly and remember that the KEY function won't work. In discharging mode, a short press of the button starts the output, and the indicator lights up. If you don't use it for 35 seconds, the indicator will turn off. To turn off the output, long - press the button for about 10 seconds. When charging and discharging at the same time, try to keep the input and output balanced to make the module last longer. Also, be aware of the temperature range it can work in (-20°C to +85°C). Don't let it overheat or get too cold. Regularly check the connections to make sure they are secure. If you have a battery without a protective board, this module's built - in protection will keep it safe. Just follow these steps and you'll get the most out of your module.
