A battery bank with a useful capacity of 100 to 200 amperes per hour is a good size to run most small 12 V refrigerators. This means that you use your battery bank only to power your refrigerator. The PLB40 power plant will power your refrigerator up to its last 1%. It is a constant regulated 12 V output.
It will ALWAYS provide a constant 12 V to your refrigerator, regardless of the amperage consumption of your fridge. What size generator do I need to run a refrigerator and freezer? How many watts does a refrigerator consume? For example, one of the most popular power plants on the market is the Jackery 1000, which can store approximately 1000 Wh of energy and has an energy efficiency of ~ 85%. Deep-cycle batteries can store much more energy than batteries found in power plants, allowing them to power refrigerators and other appliances for a longer period of time. During this period, the 2000 W power generator operating at 25% (500 W) can power a 250 watt refrigerator constantly and charge a 12 V battery (or battery pack) with ~ 15-17 amps.
The only challenge with the Jackery power plant (specifically for the 5th generation 4Runner compartment) is that its ports are on the sides, which could prevent quick access from the rear door. In addition to that, the power station offers two USB ports for you to charge your phone or anything else you need while you explore.
Portable powerplants have built-in lithium batteries and power inverters and often come with 1 to 2 110 V AC ports, combined with USB charging ports. Therefore, if you plan to power your refrigerator with a regular power generator, check the documentation that came with the refrigerator.
The two best Jackery solar generators that can power your refrigerator for hours are Jackery solar power 1500 and 2000 Pro. All that said, I think the PLB40 offers an incredibly stable and durable 12-volt regulated power and, when combined with the CFX 45, offers one of the best combinations of cooling and power configurations on the market today. While it's tempting, it's a little intimidating to power that refrigerator, especially if the first thing you think about is turning it off with the starter battery. With this, you'll never run out of power under any condition if you carry a Jackery Power solar generator with you.
These include portable power plants, deep cycle batteries combined with power inverters, and the use of portable power generators. When a compressor is turned on and requests those 12 V, but the unregulated power plant only provides 11.1 V or even 11.9 V, there is not enough voltage for the compressor to turn off and, therefore, the refrigerator to turn off as well. For example, you can power a large refrigerator during a power outage, live offline, or take the generator while camping to charge a small refrigerator.
