Review on 🧊 Icecube Mini Series 12V Portable Electric Refrigerator, Fridge Freezer, AC/DC 2-Way, Iceless Operation, Suitable for All Vehicle Types, RV, Camping, Outdoor Cooler (31qt) by Broderick Shetler

Identical to Aplicool cx30 but cheaper. Can reach much lower temperatures if you know the hidden settings. Start with the device turned on and press the power button when it is off. Then press and hold the Settings button until E1 appears. You are in! First go to E5 and use the up and down arrows to switch from Celsius to Fahrenheit. Then go back to E1 and switch to -40F! Then make sure that all E6 - E8 are set to 0. I didn't and it made my thermostat inaccurate. Start from 0 and adjust later if necessary. Now turn on the power and watch how fast this thing goes below zero. I settled on -8F as the ideal temperature to keep food frozen without the condenser running continuously. I don't use eco mode. But I use maximum battery protection. With the device powered on, press and hold the settings button, then use the arrows to toggle the battery protection level you want. I'm using h3 which turns off the device when the voltage drops below 11.1. I love this freezer and it changed my game on the road. Set the right hidden settings and this thing rocks. There's a lot more than what I've listed here. Search "alpicool hidden settings" on YouTube to find a video of Curate Adventure. The settings are the same. Also check out my photos for a hack I came up with using Styrofoam to create a little fridge space at the top where food doesn't freeze. Hope that helps.
