Sorry, the comment about physics was about the OP, not you. I acknowledge that wasn't clear.
And yes, a 10 amp charger will generate heat, but it's certainly possible. You don't need "good luck" to make it work. Just not in a small package like the OP wants.
It wouldn't just get hot, it would be BIG.And you've already complained that smaller devices are too big. There are options available to meet your needs. They may not be perfect, or exactly what you want, but they'll accomplish more than whining will.
