Ben Sim Posted August 13 Report Share Posted August 13 Hello! I just got my Deity SPD1. When powering it with my 65W Magsafe-USB-C it shows it's only getting 9V, which is not enough for my DADM226. I don't know why it is like that, because the Magsafe is supposed to deliver also 12V or more. Which USB-C power supply do you recommend / use with the Deity? And: Is there a way to set USB-C to first priority power? When I attach USB-C and a smart battery simultaniously it first drains the battery and then switches to USB-C. But what I'd like to do on my cart is using USB-C for wall power but having a battery as a backup if wall power is gone. I can't find any settings on the SPD-1 so I assume there's no way to change that priority, right? Thanks! Quote Link to comment Share on other sites More sharing options...
Display Name Posted August 13 Report Share Posted August 13 When running power over USB-C PD, all involved parts communicate and negotiate voltage and amperage. That’s power adapter, cable and device. So make sure you are using a usb-c PD cable rated with enough power you need. Could this be the reason you are seeing to lower voltage?

I don't know why it is like that, because the Magsafe is supposed to deliver also 12V or more. For some reason the Apple power bricks excluded the in between steps that is needed for the SPD-1. Therefore indeed it defaults back to the 9v. Make sure the USB supply is specced with Qualcomm Quick charge 3 or higher. I have Used chargers from Belkin, the German Hama and Anker with these specs. All with success. Per example, this one from Hama I Use/tested: https://www.hama.com/00201630/hama-5-ports-quick-charger-1x-qc-3-0-3x-usb-a-1x-usb-c-pd-51-w-black 9 hours ago, Ben Sim said: And: Is there a way to set USB-C to first priority power?

Ben Sim Posted August 23 Author Report Share Posted August 23 Thanks, I got another USB-C PD Device and now it takes 12V on the Deity. Unfortunately my main goal with this was to use wall power, but have a battery as a backup if wall power fails, but that's not possible as it takes the higher voltage first.
