#xkcd's 15th "standard" in a nutshell... #USBC is just another acronym for PITA...

In case you're wondering
- BC 1.2 ( #USB Battery Charging) is USB-Implementers Forum's basic charging protocol from 2010
- PE+ = PumpExpress Plus, Mediatek's exotic own charging protocol

I would test VOOC/Dash detection on my old OP charger but I don't have dash cables anymore... Without the right cable¹, the charger acts like a BC 1.2 5V 1.5A/2.4A charger

USB charging protocols detection on a BigBen 20 W USB PD charger, model BB8591, with a Lenovo USB C to USB C cable (dock cable from work)

I actually knew the Lenovo cable does supports USB PD.

It has taken me about 12 minutes to cool down an 18650 battery which was heating up, that it was almost too warm to the touch. The battery was in the charger which clearly doesn't properly communicate with the BMS, creating a fairly dangerous situation
The battery in someone else's hand could have spontaneously combusted into flames igniting the charger and then the wood of the table it was standing on.
I have a habit of standing up, way in the depths of the night, either because I want to go training on my race machines, or because I want to physically feel how warm the batteries are that I'm charging.

Today I'm very glad that I routinely do this, because the BMS failed, a temperature sensor is obviously absent in the charger, and the chemicals would have potentially created a runaway situation because the battery was running this hot for at least a couple of hours!

The 18650 cell delivers the energy that is needed just fine it just cannot charge to 100% anymore

Of course I have marked the cell, so I can now manually remove it from the charger

The image features a cylindrical object, likely a bullet casing, lying diagonally on a fabric surface.
LLM error it's an 18650 cell.
The object is dark brown with a smooth, matte finish, and appears to be made of metal or a similar material. It has a slightly tapered shape, with a slightly wider opening at one end. The fabric background is vibrant red with a floral pattern, including large white flowers with brown and blue accents. The texture of the fabric is visible, suggesting a woven material. The lighting in the image is soft, casting a gentle shadow beneath the object, enhancing its three-dimensional appearance.
