Question about Omnicharge 25600 Pro

the first answer is wrong. the 45W or 2A refers to charging. 3A (at 12 to 24V) is available for consumers at the dc port. so in your case 12V, 3A.
those who can read are at a clear advantage.

The manual ("Product Manual") can be downloaded from https://www.omnicharge.co/products.... In the chapter "Technical Specification" (on page 8), the maximum output power for the DC port is given as 45 watts and the maximum output current as 2 amps. 45 watts at 12 volts would theoretically be 3.75 amps.

Thus, the Omnicharge 25600 Pro delivers a current of 2 amps at 12 volts.
