Something I'd love to find is a multi-port (say 10+) PD power supply. My use case is synths and pedals that randomly take 5/9/12 and a smattering of other voltages, replacing a bunch of DC adapters with USB-C cables and a decoy module would be ideal (or one of the options above where the device already has USB Micro ports).
- johnwalkr 4y agoOne thing to watch out for (check the reviews) is most multi-port chargers have a total power maximum limit which is less than the sum of each port's maximum. So they renegotiate all ports when something is first connected. In other words, if you plug in a second synth, the first synth will probably be power cycled. Another tip: if something takes a voltage not available in PD, for example 7.5V, you can often open the device and near the power connector find a voltage regulator. In the regulator's datasheet you will often see that it will accept a higher voltage (like 9V in this example). Be aware that a linear regulator will dump the extra power as heat.
- joshka 4y agoGood points - it's likely that I won't be opening these up anytime soon. Most of the synths in question take 12V @ <800mA @ 12V (so ~10W) and usually come with a 12V 1A supply. Or they take 9V (current ranges). And there are a few that take USB power already. I'd imagine everything being either on or off and not having to hit the first problem too often. The second problem is something I'd definitely avoid. I think I only have one or two odd values (5.7V etc.) Definitely something that's more of a pipedream - I hope someday synth manufacturers will just settle on USB-C as the common power standard instead of having something different for each device.
