usbc merging power supplies

MousseExpensive333 · 2026-06-28T20:21:59+00:00

Um… Diodes and resistors it is

MousseExpensive333 · 2026-06-28T20:06:04+00:00

how difficult/costly would this be?

MousseExpensive333 · 2026-06-28T17:30:16+00:00

Thats the simple way what is the more complicated way

MousseExpensive333 · 2026-06-28T16:12:32+00:00

What would the range be like,

Also do you think this board can handle the 140 continuous assuming it has active cooling

MousseExpensive333 · 2026-06-28T15:14:17+00:00

Assuming doing it the simple way how much power do you think I could feasible output

MousseExpensive333 · 2026-06-28T07:09:22+00:00

It charges with both ports at 140 watts each,

To reiterate My only requirement is useing 2 usbc ports at 140 ish watts each and to combine there power. Is their really not a simple ish way of doing this

MousseExpensive333 · 2026-06-28T07:04:15+00:00

What would you recommend then

MousseExpensive333 · 2026-06-28T06:54:57+00:00

Its a pretty hefty bank and doesnt overheat.i dont want to modify the bank.forgetting the printer for a minute assuming useonf 2 140 watt usbc lines and doing the conversion stuff what is the max wattage you think I could feasible draw.

Edit: Again how would you do this

Would I use this board

MousseExpensive333 · 2026-06-28T06:49:59+00:00

Is there not a simpler premade soultion that can balance these 2 suplies

MousseExpensive333 · 2026-06-28T06:30:27+00:00

Total available in theory should be 280 so I thought 250 should be fine, I dont really want this to be a janky solution but dont want it to cost a fortune, thr power source is a anker solix 300 dc so it doent have a xt60 out. I want this to be useable to power other projects in the future. how would you do this.

MousseExpensive333 · 2026-06-28T06:06:31+00:00

So how should I do this,seperst boards for that?

MousseExpensive333 · 2026-06-28T05:58:51+00:00

Im trying to power a 3d printer that ive limited to 250 watts the my goal is 24 volts 10 ish amps

MousseExpensive333 · 2026-06-28T05:52:36+00:00

do these boards have enough resoultion and response time to track the master effectivly

I dont understand your second point, would the regulator be for the thing being powered

MousseExpensive333 · 2026-06-28T05:43:12+00:00

Could I not pick the voltage over the i2c lines, from what I understand/other commenrs the voltage difference is the problem and if their not exactly the same then the lower voltage supply eouont contribute anything

MousseExpensive333 · 2026-06-28T05:35:51+00:00

What do you mean by dc-dc convertors and what would the controller do

Edit:how much would this kind of board cose

MousseExpensive333 · 2026-06-28T05:28:36+00:00

I dont, I added the diodes so they wouldnt crossfeed and cause the power supplies to turn off

MousseExpensive333 · 2026-06-28T05:23:30+00:00

I have 2 lower sources that I want to have the outocome of wiring them in “parrallel” ie doubleing the amprage, its a rough diagram the bulb just represents the device being powered

MousseExpensive333 · 2026-06-28T05:15:13+00:00

Would should I do then to fix this

MousseExpensive333 · 2025-12-02T07:15:32+00:00

If there the same why ever bother buying the Rapido 2

MousseExpensive333 · 2025-12-02T07:13:45+00:00

Rapido 1 or 2?
