To adjust the voltage we have to do couple of steps. Connect the converter with the battery or other power source. Know how much voltage you have inputted in the converter. Set the multimeter to read the voltage and connect the output of the converter to it. Now you can already see the voltage on the output.
This is a buck converter meaning that it will take higher voltage and convert it into lower voltage. To adjust the voltage we have to do couple of steps. Connect the converter with the battery or other power source. Know how much voltage you have inputted in the converter.
Connect the converter with the battery or other power source. Set the multimeter to read the voltage and connect the output of the converter to it. Now you can already see the voltage on the output. Adjust the trimmer (here 100k Ohm) with a tiny screwdriver until the voltage is set to the desired output.
As the battery state of charge increases, the battery voltage levels off to a constant float voltage. R9 reduces the maximum output voltage of the converter thereby setting the float voltage. R8 and the forward voltage of D2 set the minimum current source voltage. This determines the minimum load impedance the source can safely drive.
This is a boost converter meaning that it will take lower voltage and convert it into higher voltage. To adjust the voltage we have to do a couple of steps. Connect the converter with the battery or other power source. Set the multimeter to read the voltage and connect the output of the converter to it.
You don't "adjust" output current. Loads draw whatever amount of current they need, provided the power supply can deliver it. If your total load exceeds the buck converter's rating of 3A, then you will be overloading it. If your total load is less than 3A, then you need not adjust anything.

Figure 1. A simplified inverter schematic. Image source: ElecCircuit. How it works: Q1 is turned on. Current flows from +12V through CT (centre-tap) to the top of the transformer.
Choosing power supply, how to get the voltage and current …
BUT trying to operate a 12V rated device from a 16V supply (25% high) is risky and may cause damage to device or supply. Current: A device that draws a specified current can be operated from a supply able to supply the same or higher current. eg consider a 12V, 2A device and a 12V 20A power supply. 12V is the "electrical pressure".
voltage
A circuit pulls an amount of current from the source. The source does not feed its rated current into the circuit. So you don''t need to do anything to ''reduce amps''. When selecting your power source you need the correct voltage and at least the required current. The circuit will only draw as much as it needs.

Battery-operated generators are essential devices that convert battery power to alternating current (AC) in order to provide electricity when no other power source is available. It is important to properly maintain and upkeep these converters …
How do constant current constant voltage devices work?
The devices work by not being constant current and constant voltage at the same time. You set a voltage (V) for the output. You set a current (A)for the output. It will supply constant V for any current up to A. When the current your circuit draws goes above A, then it will reduce the voltage to keep A at the value set. Example: V set to 10V; A ...
