We like this warmer and power bank
I tried other warmers over 4 times and return it since those products shows wrong LED display charging and functionality. But this one is different. This warmer controls heating period itself to save its power for heating. It doesn't push the heat continuously but it acts like push and stop and push again. We like this and will keep for the winter season and want to make my wife's neck warm with this warmer. AND.... it really charge my phone quickly. It's real.....
