There's no way an 8 inch cable works for you. 8 inches wouldn't even span the distance from my car charger to a phone clamp or from my computer to my desk.
3 ft is barely tolerable for me. 6 feet gives me enough room to move my phone around.
8 would work for my desk, my car, my bed and the one that sits on my counter. 3ft is too much cord and I end up with a lot hanging. 6ft is definitely too much.
Then again I don’t use anything when it’s charging, so my use case is out of the norm
Not sure why people are downvoting you. Your use case is valid but definitely not the norm. My charger is below my nightstand so I end up needing a 3+ foot cable to rest my phone on the surface.
After taking a cursory look of where plugs are located in my house, I think I'll have to put my phone on the floor when I charge it if the cable is only 20cm long. 80cm is the minimum to be able to put the phone in a table while charging.
Edit: disregard that, the plugs are 30cm above the floor so my phone would be hanging by the cable.
