1) How inefficient is it to boost 12V to 120V and then back to 12V as in using a traditional car power inverter to power a laptop (i.e. the 12V car battery power is boosted to 120V by a power inverter and then back to 12V by the laptop’s power supply)? 2) Is there any way to power a laptop directly from a 12V car battery?
Can a car inverter be used to power a laptop?
1) How inefficient is it to boost 12V to 120V and then back to 12V as in using a traditional car power inverter to power a laptop (i.e. the 12V car battery power is boosted to 120V by a power inverter and then back to 12V by the laptop’s power supply)? It depends on your hardware, but it’s not too terrible.
Can a laptop be charged from a car battery?
