Ozito PXC 20V 100W USB-PD & USB-A (QC 3.0) Charger

thingiverse

I designed this 100W USB-PD/A (QC 3.0) charging box which plugs into an Ozito 20V battery. This is ideal as it completely charges up my Macbook and other USB-PD laptops at a full 100W. You can either print the top with USB-PD only or a dual USB-PD & USB-A (QC 3.0). Items required: 1. Ozito PXC 20V battery 2. SW2303 charging module/board (you can get this from ebay or Aliexpress). Some people have reported issues with some of these boards where it doesn't sustain 100W but I received a v1.1 and it was able to sustain a charge for an hour at 100W. 3. USB-A QC charging board for USB-A charging: https://www.aliexpress.com/item/32953580059.html 4.
