Simzlife 12 Volt Refrigerator, 49QT(45L) Portable Car Refrigerator, Dual Zone, Mini Fridge with Wheels

Does not kill your battery over night. Same setting will sometimes freeze contents and other times barely chill them in the same ambient/outside temperature.

it worked great for 3 full weeks . and I will use it from now on'

I bought the cooler and these are my impressions after a few days. These are things I wondered about before buying it but couldn't find the answers.Power consumption:The (that's a silly name) 30 qt cooler uses a long-term average of about 14 W of electricity when the setpoint is 35 F and the outside temperature is 72 F. In practice, the compressor runs for a couple minutes at 30-50 W and then shuts off for a while. My 660 Wh power station can power it for about 48 hours.There is no difference between the "eco" and "max" modes in the long-term power consumption. From basic physics, the power consumption is going to scale with 1) the temperature difference between the inside and outside of the refrigerator, and 2) the insulation of the refrigerator. Electronically switching between "eco" and "max" doesn't change any of these things.The outside of the cooler is quite cold to the touch, which tells me that its insulation isn't very good. sells a jacket for $50. However, I bought some 1/4" aluminum foil insulation for $10 and will make my own jacket. I suspect this will work better than the OEM option. I'll update this review with the new power consumption once I build/test that.Temperature stability:The temperature stability is... not very good. I put a wireless thermometer inside the cooler in order to remotely track its temperature. When I set the cooler to 33 F, my thermometer was reporting 30-33 F and the cooler was self-reporting 28-32 F. I increased the setpoint to 35 F. Then my thermometer reported 31.8 - 35 F, and then cooler's temperature gauge again claimed it was below the setpoint. I'll probably set the cooler to 36 F in the future to avoid stuff freezing. There were no items inside the cooler except the thermometer during my testing. It might be more stable when filled with stuff due to the thermal inertia? I'll probably leave a thermometer inside when using the cooler in order to track its performance, since I don't trust its self-reported temperature.Difference between models:This is the basic version of the cooler. The CRPRO30 has the same capacity but is slightly bigger on the outside. It has strap tie-down points, a cubby for storing accessories, and an internal LED. The CRPRO30 VIP has the same features as the CRPRO30 but better insulation.

Have only used it on 120V but it gets cold and fast. Pretty quiet too. I need to test it on 12V but I'm confident it will work well.

Works great. Keeps things cold even on hot days
