Customer Reviews
Customer Review: “I have had this freezer/frig for almost 8 months now. Have used it on several week long camping trips and it has not failed me yet. I have had it run on my 12v 100 amp Li iron po4 battery for 4 days(at zero degrees F) and the battery was down to about 29 % charge left… You can hear it running but it is not very loud at all, no problem with sleeping and it in your camper. It cools down pretty fast, but think it would be better to have most items frozen first if you are using it as a freezer. I seldom use it as a frig. but functions fine in that mode… Yes, I would buy another if I needed one and recommend this unit to you!Update 7-13-24: Just got back from an extended 2 week camping trip. The frig continues to impress me and worked great the whole time with minimum power consumption from my lithium 12v batteries… Update 2-1-25: Had relatives come visit for 5 weeks and used the frig/freezer in our camper. Worked great and they thought it was ‘neat frig/freezer’. I have had it for about 4 years now and I am very satisfied with my purchase.”
Customer Review: “This is a great portable refrigerator. We got the large 53 Quart size, and glad we did, we can never have enough stuff when we go camping! We haven’t had a need to use the freezer option with this unit so we have just used the entire unit as a refrigerator and it works amazing! We go off roading and camping and this unit straps down in the back of the Jeep and holds on like a champ! We got it with the insulated cover which I think is a necessary item for helping with insulation as well as strapping it down as the cover comes with straps… Very happy with this portable refrigerator and the value for the money as their are definitely brands out there that can run $800 and more that do exactly the same thing, keep your food and drinks cold… I read a couple of other reviews and noticed a few complaints about the heavy springs in the handles, they must have fixed this issue before we bought ours as we do not have any problems with the handles, they work great!”

Customer Reviews
Customer Review: “Very good camping fridge. I like the cooling aggregate which is variable speed. When needing less cooling (close to target temperature) it draws less power. It is not loud or unpleasant, just a whirling hum… In real-world, very good fridge! We enjoy having a real fridge and not needing to mess with ice. Friends are surprised about nice and cold beverages right on the campground. You could even have your own ice cream (using it as a freezer). Albeit, it still gets wet inside the fridge due to condensation — we don’t dry things off when putting it back… Power consumption is much higher in the real world (open/close, putting food/drinks back in that are no longer as cold). I did not measure (busy camping), but I would guess 250Wh in a 24h period using it as a fridge (34F set point — which is a bit too cold).”
Customer Review: “If I could give this 10 stars I would. Who would have thought that a 12 volt refrigerator freezer could be this great and efficient. The inverter compressor is very quiet constantly adjusting is speed to efficiently use power. The most this device pulls is 2.5amps or 37 watts. It can easily flash freeze by dropping the temperature down to -8 F. I never have to waste my money on ice again… I bought 2 batteries so I can keep Italian ices in it at -4 degrees all day. It’s always great to bring a meat freezer with you when you buy ice cream in the summer. You can get it home without it melting… Other than that one tiny gripe this is truly the best gadget ever invented.”

Complete Buying Guide for Built In Side By Side Refrigerator Freezer
Essential Factors We Consider
When evaluating built in side by side refrigerator freezer units, we prioritize several key aspects: capacity vs. footprint, energy efficiency ratings, installation requirements, and feature sets like alarms or smart controls. For built-in models, ventilation access and depth compatibility with cabinetry are critical. Portable versions emphasize power source flexibility and weight distribution.
Budget Planning
Expect to pay anywhere from $400 for basic mini fridges with freezers up to $3,000+ for commercial-grade side-by-side units. Entry-level options serve dorms or offices; mid-range models fit most homes; premium picks include hospital-grade alarms and custom paneling. Always factor in shipping, installation (if applicable), and extended warranties when budgeting.
Final Thoughts
Choosing the right built in side by side refrigerator freezer depends entirely on your lifestyle and space constraints. Whether you’re outfitting a tiny home, expanding a catering operation, or simply need extra cold storage, there’s a solution here that balances performance, price, and practicality. Trusted brands like Summit and BougeRV prove that even compact designs can deliver enterprise-level reliability.
Frequently Asked Questions
Q: Can I install a side-by-side fridge/freezer underneath my counter?
A: Absolutely—many models like the Summit series are specifically designed for undercounter installation. Look for “front-breathing” or “built-in ready” specifications to ensure proper airflow without protruding sides.
Q: Do portable fridge/freezers really save money compared to traditional coolers?
A: Yes! Modern compressors consume far less power than ice-based systems. Over a summer of camping, a quality portable unit can eliminate dozens of ice purchases and reduce battery drain significantly.
Q: Are side-by-side models harder to organize than top/bottom freezers?
A: Not necessarily. The main challenge is reaching deeper shelves, but most include adjustable racks to optimize access. Plan your layout ahead of time—and avoid overloading the doors!
Q: How often should I defrost a manual-defrost portable freezer?
A: Usually every 6–12 months depending on usage. If you notice thick ice buildup (>¼ inch), it’s time. Some users prefer semi-annual cycles regardless to maintain peak efficiency.
Q: Can I use these fridges outdoors year-round?
A: Only if rated for outdoor use. Most portable models handle moderate climates, but extreme heat or cold affects performance. Always check manufacturer specs for operating temperature ranges.
