I have some simple questions regarding power on the T7:
What is the DC barrel measurements for the power connector? Inner and outer diameter.
On the unit it states 18.5V 2.59A (odd power choice btw), is there some wiggle room? Would it work with 20V or would I fry the unit? I'm asking because I plan on using my T7 with a USB-C powerbank with PD and PD only supports 5V, 9V, 12V, 15V and 20V. I can use a step-down buck converter but would be nice to avoid if possible. (BTW the purpose is to use the T7 anywhere outside where I have no access to a wall socket)
Hello D-One,
The barrel DC jack built in T7 DJ controller is a standard 1/4" barrel DC Jack.

so the male connector on the power supply side should have the standard dimensions for such plug:
Outer sleeve diameter: 5.5mm
Inner sleeve diameter: 2.1mm
Outer sleeve barrel length: 9.5mm
Inpulse T7 works with a 20V 3A power source. The 18.5v 2.59A label looks like a certification laboratory request after the lab has probably tested the included power supply and found it delivers this power.
Thanks so much Mibzic, that helps a lot. Now I don't need to buy a bunch of DC Plugs to try out. I really appreciate you taking the time to reply!

Regarding the voltage. Are you giving an educated guess or are you absolutely sure of this? I'm terrified of frying my T7 by giving it too much voltage 😬
Hello D-One,
Welcome to the user forum.
Sorry, DJControl Inpulse T7 really needs a 18.5 Volt power source with 2.59 Ampere.
So you cannot power the T7 on a USB-C power supply delivering 20 Volt 3 Ampere.
For the other part, Micbiz is right, the DC jack is a standard 5.5 x 2.1mm barrel.
If you use a powerbank, 18.5v LIPO batteries are pretty standard for drones and DIY tools, but you must make sure the battery actually delivers 18.5 volt since if the power comes at another voltage, it will change the platters rotation speed.

Oohh.. I see. Thanks very much. I ordered this: https://lectronz.com/products/ppstrigger-board, it should do the trick.
Hello D-One,
I do not know this device so I cannot tell you it will work, but it seems workable if the output voltage set @ 18.5v remains at 18.5v.
If the power goes at 20 volt, it should not damage the T7 controller, so it is not terrifying, but as the device is set for 18.5v,
- the platter rotations and sound are OK with a 18.5v power source,
- while platter rotations and sound become not OK if the power source is at 20v
and 5A intensity is OK.
