Hi,
i contact you for this mac, the board is very clean. The mac no charge (the tester stay black, no power)
i find D3300 and D3400 short, i change it and after it work well. i think it's good but, the customer come back, D3400 is short again.
i find the mac is very slow for change 5V to 20V (10-20sec). what is causing this?
thanks

Can take 3-5s to switch input voltage, that is not a big problem.
But fake charger can damage the board.
