- TL;DR Summary
- Can electronic devices be used on "dirty" portable generators if the power is run through a power supply/adapter that converts the 120V/60Hz power to DC voltage to clean it up (for example, a laptop computer).
I have a portable generator that I use for backup power at my home in case of a loss of power. I understand that the power from these generators is not clean because both the voltage and frequency are not very stable and this is bad for sensitive electronics and may even damage them. I am wondering if this dirty power can be cleaned up by running it through a power supply that converts it to DC low voltage, as in the case of laptops and cell phones. It would seem to me that since most of these power supplies can take an input of 100-240V 50/60Hz, and output the correct DC voltage, this conversion process would clean up the power going to these devices (laptops and cell phones) and it would be OK to use these devices on generator power. I have not been able to find any information on this subject and I am hoping someone with an engineering background on this forum can help. Thanks.
