The holder will arrive flat packed alongside some instructions on how to construct it. The holder will only support a SumUp Solo Machine, and the machine has to be affixed with the white SumUp cradle. You must order the cradle separately. 

When the machine is in the cradle, you can then charge this machine as you use it. As you can see from the photos, the charging wire from the cable comes neatly out of the back of the holder. The card reader must be sat in the white cradle to be used with this holder - if you just affix the machine, people cannot access the card slot at the top of the machine.
