Q:Can I use the solar generator at the same that it is charging?

Yes. This is called pass-thru charging and it’s one of the most important features when considering any solar generator. This is because pass-thru charging is what allows you to use a solar generator as a long term/off grid power solution.

You can run your devices all day and night while simultaneously charging the generator during the 5-7 good sun hours each day.
