Power distribution for Charge cases ! (different voltages for chargers with one power Brick)

[WrineX]

Hi there, it has been a while ! hope you guys do well?

I had this question been ask multiple times now when implementing my chargers into a charge case..  CAN I GET RID OF ALL THOSE POWER BRICKS!!!

and well the answer is yes for me ! my chargers can hande around 12-30 volt witch makes it more easy to mate with other chargers powered by one power supply , as well as it can use 24 volt and halve the current requirements for cables and or plugs..... BUT

one has many more chargers in the case and they are often not able to do so. So i wondered... maybe i could make a product that can convert from 24Volt to a few set voltages , so we can use a big power brick or somthing else instead of multiple bricks. 

now my question is , what do you have in your charging cases ?  (i am not been on a set for years so). name and number please so i can lookup there requirements. i noticed many have a AA charger thats are fed 5 volt, some have things running on 12 volt.. and my chargers run from 12-30 volt.  
i would love to know what voltages used mostly and how much they draw, and or how many are used..  so a list of what you have in your charge case would be nice and i do the rest
I hope you can help me out !


Kind regards Joppe Peelen

I have switched to all USB (battery chargers etc.) with PD and such it's way more efficient this way, no more headaches wth 110 V vs 220 V while travelling. all hail USB-C.

As it sits today:

 

 

there are poly fuses on each charger. The wiring’s a mess right now as I swapped out the AA chargers mid show and haven’t cleaned up. The xtar chargers are usb-c and I still need to add Buck converters to move them onto the distro. As always, the carts never done. I really like having everything wired to a single 4 pin xlr. I can pull the drawer off my cart and put it in a pelican, or i can charge small batteries from my LifePO4 bricks i use on my main cart. On the cart they are powered by a meanwell 12v supply
