draw double amount of current from multiple ac-dc-adapters

[niceguy77]

Hi, i'm fixing dc-ac-inverter. But wants to do the job in the room, not in the garage while car engine is running.

Now i've got 4 ac-dc-adapters with 12V 4A output.

Is it possible to draw 12V 4x4=16A by connecting 4 adapters in parallel?

If ok, do I need to add schottky diodes to keep from reverse voltage attack from each other adapters into each adapters?

Thanks in advance~

Yes, it is better to use a diode (does not need to be a schottky one unless you need this extra voltage drop cause by the normal diode). The diode will ensure that when one adaptor is on, there is no current flow to the others that may cause any problems.

Thank you Platonas~!

1. Do you mean it's ok (even though not 'BETTER') to connect adapters in parallel without diodes?

2. Are you sure this combination will provide 4 times of 4A = 16A current?
