Tyfo's charging bank

thingiverse

I was lacking a 6-way USB charger where **ALL** of the ports are powerful. Most of commercially available solutions offer one, maybe two "fast" charge ports and rest a regular 5V, plus often the "fast" charging standards are limited. Also the prices don't make my wallet happy and I managed to make this one below 25Eur in electronics. This design holds 6 independent USB charging chips, takes power from an XT60 or USB-C module. For **output** I used CKCY-U1A board that I bought from [here](https://allegro.pl/oferta/ladowarka-usb-qc2-0-3-0-przetwornica-rt0145-9892218184), obviously 6 is needed. These are great since they work from 6V to 32V and also the charging protocol variety is nice. For **input** power I used two solutions that fit nicely in the back of the bank: + USB-C PD based on PD2721/IP2721 that I bought [here](https://allegro.pl/oferta/tester-wyzwalacz-ladowarek-quick-charge-qc-pdc-20v-10822077766) which give 20V to the internal power rail + XT60 port (which also powers up when USB-C input is is connected) Internally everything is connected with a piano wire and carefully set in place with a dab of super glue and epoxy after soldering. I did not design a cover but you can easily print the part again limiting height to 2mm.
