Any luck powering an original holy grail off a unit like this? The highest power tap is 450ma. I know the original adaptor was 500ma, but I’ve also read someone on here that the original HG only draws around 250ma? I’d love to be able to power it off the iso brick to save lugging an extra adaptor

Thanks!

If the polarity and voltage is the same it will work.
