I'm not sure if the charger in question is supposed to charge the latest Samsung at 45W. However, according to some information available, Ugreen 65W chargers generally only support 25W for Samsung Super Fast Charging 1.0 and do not support Samsung Super Fast Charge 2.0 at 45W. For more details, I recommend that you consult the official product documentation or contact Ugreen customer service.

This must be done and is a safety feature. When a new device is plugged in, the handshake is performed again for all connected devices to ensure that no more power is requested than the charger can provide.

The folding power connection is the US connection, because only this connection is very elegant and easy to fold out because it is flat. Our Euro connectors are round and the Chinese never make them foldable.

It comes with a 2p Euro plug. Why Digitec also linked the US and UK versions is probably a clerical error. https://u-green.ch/products/ugreen-4-fach-usb-c-power-delivery-ladegeraet-gan-x-pd-65-watt-schwarz?_pos=1&_sid=828a7b5e9&_ss=r
