Off-The-Grid Powered Cooler

Jackery Explorer 300

By Jon Crowley

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.

Here is more information on the setup:

  • Jackery Explorer 300 – the ideal power station for short camping trips and power outages because it’s compact size and functionality. With 293Wh power capacity, it is capable of powering small appliances and charging up to six smart devices at once.
  • Jackery SolarSaga 100W – Monocrystalline Solar Panel, stay charged with the power of the sun! With high conversion efficiency up to 23%, it’s ideally suited for outdoor life and even unexpected power outages. The solar panel weighs only 9.1 lbs, it’s lightweight, foldable and portable with an easy-carry handle.
  • ICECO JP40 Powered Fridge/Freezer – 43 quart capacity with Adjustable Temperature From -7℉~50℉ powered by a high quality SECOP (Danfoss) Compressor.

I started off the test in the late morning.  High temperature for the next few days was 95 degrees and the low was 65- 75 degrees. The Explorer 300 was charged to 100% and we had the SolarSaga 100W panel connected, BUT the drinks I put inside were warm and the cooler was currently at 79 degrees.

Would the Explorer 300 be able to get the JP40 down to 36 degrees in 95 degree outside temps using just the solar panel to keep it charged? Would the Explorer 300 have enough reserve capacity to last overnight before the sun came up to charge up again?
