We’ve used our Jackery Explorer 1000 to power our ICECO JP40 cooler for a few months now and love it.  Only issue is sometimes it would be nice to have something smaller and more nimble. I decided to get a Jackery Explorer 300 to give it a try.  I wondered whether it would be able to power our ICECO JP40 overnight, then recharge enough during the day using a SolarSaga 100W solar panel to be able to do it all over again the next night.
