Ripcord 18v usb cable for Pallette case

Hey wondering if the ripcord 18v usb power cable would be safe to use with the palette case for power? If anyone could help me figure this out it would be super helpful.

It’s hard to say. They don’t specify the milliamperage or barrel size. I’d say probably not, because the Palette is 15V while this is 18V.

According the Amazon page, it only provides 9 Watts of power, the Palette has a 30-watt power supply and a 40-Watt Power Brick. This would be really under-powering it.

Cable length: 1.5 metres
Power input: 5V USB 1.0, 2.0, 3.0
Voltage output: 18V
Power output: 9W max
