<p></p> <p><b>New page</b></p><div>Hi,<br /> <br /> Please confirm your &#039;&#039;&#039;X820 version&#039;&#039;&#039; first. The updated &#039;&#039;&#039;V3.0 model comes with a 5521 DC port&#039;&#039;&#039; instead of 5525.<br /> <br /> # &#039;&#039;&#039;USB-A:&#039;&#039;&#039; No current limit; max output follows the power supply.<br /> # &#039;&#039;&#039;Two 2-Pin XH2.54:&#039;&#039;&#039; 3A rated per connector, no built-in current limit.<br /> # &#039;&#039;&#039;USB-A and the two XH2.54 ports share the 5V input current.&#039;&#039;&#039;<br /> # The board won&#039;t get damaged even with a 5V 100A power supply. &#039;&#039;&#039;BUT:&#039;&#039;&#039; <br /> #* &#039;&#039;&#039;surge voltage or overvoltage will burn the chips&#039;&#039;&#039;<br /> #* &#039;&#039;&#039;the matched 2-pin power cable is rated at 4A maximum&#039;&#039;&#039;<br /> <br /> So, direct use of a 5V 10A power supply is okay in theory. You can also use a screw terminal adapter to power each component individually.<br /> <br /> Hope it clears things up!</div>
