6 FAQs about [One power supply to power two sets of batteries]

How does a power supply work if multiple devices are connected in parallel?

Each device draws only the current it needs. Even if multiple devices are connected in parallel, the current of each devices doesn't change. But the power supply need output that total current. Read more about more academic theory below. Andmore. In other story...

How many Watts Does a 12V 3A power supply consume?

My power source is 12v 3a. In other words, It is a power supply with an output capacity of 36W (12V * 3A). First, Device "A" consumed 12V 1.7A, which is 20.4W. The power supply still has 15.6W of spare capacity. Second, Device "B" consumed 5V 2A, which is 10W. But the with DCDC converter connected.

How does a power supply work?

And if not why this would happen. The power goes from the supply to each device independently until the point the supply becomes overloaded. Each pulls the current it wants and the voltage is kept constant by the supply.

How does a 3A power supply work?

The power goes from the supply to each device independently until the point the supply becomes overloaded. Each pulls the current it wants and the voltage is kept constant by the supply. However drawing 2.7A from a 3A supply is not great, you want a bigger margin than that for reliable running, not good to run a supply hot.

Can a 12 volt switch drain a battery?

Not only will that drain the batteries, but it could have strange consequences to either or both circuits. Use a double-pole switch or two separate switches. Another possibility is to create the 5 V power from the 12 V power. Then you only need to switch the 12 V for on/off. Others have already said it just to make things clear here's a diagram.

How much power does a 12V converter consume?

The converter consumes 1.05A from a 12V power supply (12.5W, because 80% efficiency) to output 5V 2A (10W). Now, The total output of the power is 20.4 + 12.5 = 32.9W. The current is 2.74A at 12V. Don't you think this fits in the power capacity you described?
