I mentioned earlier I’m using the INIU 20000mAh 65W, model number P62-E1. Well I’m now having some issues with it. When the Tonverk is starting up, sometimes after the “test pattern” screen the power bank will just turn off. I’m not sure if the TV briefly stops drawing power, or sends an incorrect PD signal to the battery, but I’m not sure I’d recommend this one at the moment. I’ll file a bug report since it seems like an interaction with the TV. (It always powered DTII flawlessly, and seems to work as it should with other devices too.)
