myVolts Ripcord 9V DC center negative

Bought this for HX Stomp, as the internet suggests it works. I already tried two units - they seem to overheat in like two hours of use with the Stomp. After that, in like several minutes. Tried with a few powerbanks and power adapters that do deliver 5v 2.4a, or more. Also, the usb fit is not tight enough to inspire confidence.
Now the thing is, this Ripcord is rated for 1A, and the Stomp might be drawing bit more than that, which might be why the Ripcord stresses out. Technically, the stomp is rated for 3 amps, so technically it should not work, although many people have success with this. As far as other pedals go, with less current draw, this works perfectly!
The adapter works with 2.1 and 2.5 dc sockets, so regular pedals as well as Line 6.
If you want to power the Stomp, look at USB C power delivery (PD) adaptors and a PD compatible (!) powerbank. Such adaptors tell the powerbank to provide 9v. I found a powerbank that can do 9v 2.2a, which is plenty for the Stomp.
Now, thomann, when I contacted them about the issues I had, just sent me a second unit. Customer experience - excellent!
