What amount of current should I use to charge a 12V car battery?
There is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and <= 10A is more favourable to prolong lead acid battery. However, better read the battery specs and datasheet to find out. Example: Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A.

Is it safe to charge a low-current device with a battery charger?
It is safe to charge a low-current device with a battery charger only if it is designed to charge such devices. Most power banks are not compatible with low-current devices and treat them just like any other smartphone. This may cause them to send a high-intensity current which can damage your device.
What is battery charging?
Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.
How does state of charge affect battery charging current limit?
As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC. Here, Open Circuit Voltage (OCV) = V Terminal when no load is connected to the battery. Battery Maximum Voltage Limit = OCV at the 100% SOC (full charge) = 400 V.
