Does A Laptop Charger Use Electricity When Not Connected. We plugged in a variety of chargersiPhone iPad MacBook Android phone and tablet Windows laptop Chromebook and even Nintendos 3DS charger. From my experience my old Thinkpad charger as well as both my MacBook and MacBook Pro chargers over the years have never been warm when not actively charging anything.
But how much power does it consume. Can this damage the charger laptop or electrical installation. Assuming you use the same energy plugged in and not youre probably better off staying plugged in because energy is lost in the process of charging the battery storing the electricity and then.
But how much power does it consume.
Even if battery charging systems have improved since then common sense suggests that using AC power requires less energy. A degraded battery will consume more energy than a healthy one. Do not plugunplug your laptop unless necessary. Always use the recommended chargeradapter.
