> Always sad for me to know how much popular are wireless chargers, wasting 47% more energy aprox for charging the same as a wired charger. TBH some wired chargers are only 60 percent efficient in converting AC to DC. Then you'll also have energy losses inside the phone converting 5vdc to 3.7vdc for the lithium battery. But, what? this is ~7 watts per charge completely full charge? One could do the following and offset those 7 watts with a lot more to spare: Add another layer of insulation. Add a heat pump. Add solar panels to your roof. Stop mining Bitcoin. |
