Reviewing the Kia Carnival Portable Car Fridge: 36L Capacity Test
There’s a specific moment in the Kia Carnival—when you’re packing for a weekend camping trip and realize the cooler you’ve been using for years just isn’t cutting it anymore. The ice melts by noon on day two. The sandwiches are soggy. The drinks are warm. And your family is giving you “the look.”
Enter the portable car fridge. Specifically, the 36-liter models that seem perfectly sized for the Carnival’s massive cargo area. I’ve spent time digging into real-world tests, owner experiences, and capacity comparisons to answer the question: Is a 36L portable fridge the missing piece of your Carnival adventure setup?
TL;DR
A 36-liter portable car fridge is an ideal match for the Kia Carnival. It fits easily in the cargo area with the third row up, offers enough capacity for a family of four’s weekend provisions, and runs efficiently on 12V power without draining your battery . The Carnival’s 12V outlets and available auxiliary battery options make it a natural fit for extended trips . Top contenders include the Setpower PT35 (tested at 36L actual capacity), Iceco GO20 (dual zone), and Dometic CFX3 35 (premium choice) . Expect to pay $300-$900 depending on features .
Key Takeaways
- Perfect Size: 36L fits behind the third row with room to spare, or slides easily into the footwell when seats are folded .
- Actual Capacity Matters: Advertised capacity isn’t always accurate. The Setpower PT35 tested at 36L actual capacity, matching its specs .
- Power Consumption: Quality 12V fridges draw 2-5 amps when running, cycling on/off to maintain temperature. The Carnival’s electrical system handles this easily .
- Dual-Zone Options: Some 36L models offer dual-zone cooling, letting you freeze items on one side and refrigerate on the other .
- Installation Flexibility: Most units can be hardwired or run from the 12V outlet. Consider a secondary battery for extended off-grid use .
Why a Portable Fridge Beats a Cooler
If you’ve ever dealt with a traditional ice chest, you know the pain points:
- Ice melt: You’re constantly draining water and buying more ice
- Temperature swings: Everything floats in meltwater, and nothing stays consistently cold
- Space inefficiency: Ice takes up valuable cargo room
- Limited duration: Beyond 2-3 days, you’re fighting a losing battle
A 12V compressor fridge solves all of this. It maintains a consistent temperature (usually 0°F to 50°F), requires no ice, and runs indefinitely on 12V power as long as your battery holds out . The Carnival’s spacious interior and multiple 12V outlets make it an ideal platform.
One owner tested their 36L fridge on a four-day camping trip. They ran it continuously from the vehicle’s auxiliary battery, kept everything cold (including ice cream), and never worried about draining the starter battery .
The 36L Sweet Spot: Why This Size Works for Carnival
The Carnival offers flexible cargo configurations. Here’s how a 36L fridge fits:
With Third Row Up
- Behind-third-row space: 40.2 cubic feet (about 1,138 liters)
- 36L fridge footprint: Typically 20-24 inches long, 12-15 inches wide, 16-20 inches tall
- Result: Fits easily with room for luggage, groceries, and gear around it
With Third Row Folded
- Cargo area: 86.9 cubic feet (about 2,461 liters)
- Fridge placement options: Slide it anywhere—behind second row, in footwells, or secured to tie-downs
- Result: Virtually unlimited placement flexibility
With Second Row Removed/Stowed
- Maximum cargo: 145.1 cubic feet (about 4,108 liters)
- Fridge placement: You could fit multiple 36L fridges and still have room for camping gear
The 36L size hits the sweet spot: big enough for a family’s weekend needs, small enough to be portable and easily stored when not in use.

Visualizing Capacity and Features
To help you decide which fridge matches your needs, here’s a comparison of key factors.
*Relative scores based on key features for Carnival owners. Higher is better.
Real-World Capacity Test: What Fits in 36L?
Numbers are abstract until you visualize actual food. Here’s what you can typically fit in a 36L fridge:
Scenario: Weekend Trip for Family of 4
Day 1-2 Provisions:
- 1 gallon of milk
- 12-pack of soda/beer
- 1 pound lunch meat
- 1 pound cheese
- 1 dozen eggs
- 1 pound butter
- 1 container yogurt (6-pack)
- 2 pounds ground beef (for burgers)
- 4 chicken breasts
- 1 bag salad mix
- Condiments (ketchup, mustard, mayo)
- 4 apples
- 4 oranges
- 6 yogurt tubes (kids)
- 1 juice bottle
Result: Fits comfortably with room for ice packs if needed.
Scenario: Extended Trip (5-7 Days)
For longer trips, you’ll need to supplement with dry goods or resupply. A 36L fridge holds about 3-4 days of fresh food for a family of four. After that, you’re either shopping or using non-perishables.
Powering Your Fridge in the Carnival
The Carnival offers multiple power options for a portable fridge.
12V Outlets
- Location: Center console, cargo area (depending on trim)
- Capacity: 10-15 amps typically
- Usage: Plug and play, no wiring required
- Caution: Ensure the outlet remains powered when the vehicle is off (check your settings)
Hardwiring
For permanent installations, you can hardwire the fridge to an auxiliary battery or directly to the fuse box with appropriate fusing and a voltage cutoff relay.
Secondary Battery
Serious overlanders often install a secondary battery (house battery) in the Carnival’s cargo area. This allows the fridge to run indefinitely without risking the starter battery. The Carnival’s spacious under-floor storage is a prime location for an auxiliary battery setup .
Solar
Portable solar panels (100W-200W) can keep your fridge running indefinitely when paired with a charge controller and secondary battery. The Carnival’s roof rails can accommodate solar panels when parked .
Pro Tip: Most quality fridges include a built-in battery protection feature that automatically shuts off the fridge if voltage drops below a safe level (usually 11.5V-12.0V). This ensures you can always start your Carnival .
Installation and Setup Tips
Securing the Fridge
The Carnival’s cargo area is spacious, which means your fridge can slide around if not secured. Options include:
- Cargo tie-downs: Use the built-in anchors with straps
- Fridge slide: Install a sliding platform for easy access
- Non-slip mat: Prevents minor movement
Ventilation
Compressor fridges generate heat. Ensure at least 2-3 inches of clearance around the ventilation grilles (usually on the sides or back). The Carnival’s cavernous cargo area provides plenty of airflow .
Pre-Cooling
Always pre-cool your fridge at home (plugged into AC power) before loading it with food. This reduces the initial power draw when connected to your Carnival.
Temperature Settings
- Refrigerator mode: 34°F to 38°F
- Freezer mode: 0°F to 10°F
- Dual-zone models: Set each side independently
FAQ: Kia Carnival Portable Fridge
1. Will a 36L fridge drain my Carnival’s battery overnight?
Quality fridges with battery protection will shut off before draining the starter battery. A fully charged Carnival battery can typically run a fridge for 12-24 hours, depending on ambient temperature and fridge efficiency . For longer trips, consider a secondary battery.
2. Can I run the fridge while driving?
Yes. The 12V outlet in the Carnival is powered when the vehicle is on (and sometimes when off, depending on settings). The fridge will run off the alternator while driving, preserving the battery .
3. Where should I place the fridge in my Carnival?
Popular locations include:
- Behind the third row (easiest access)
- In the footwell of the second row (if third row is folded)
- Secured to the cargo floor with tie-downs
- On a fridge slide for easy access
4. Do I need a dual-zone fridge?
It depends on your needs. Dual-zone is great for freezing meat while keeping drinks cold. Single-zone is simpler and offers more usable space in one compartment. Families who camp frequently tend to appreciate dual-zone .
5. How much do these fridges weigh?
Expect 30-45 pounds empty. Loaded with food and drinks, they can exceed 50-60 pounds. Consider this if you’ll be moving it frequently.
6. Can I use the fridge at home?
Yes. Most portable fridges include an AC adapter for home use. They make excellent backup freezers or extra refrigerator space during holidays.
7. Will the fridge fit under the Carnival’s cargo cover?
Most 36L fridges are 16-20 inches tall. The Carnival’s cargo cover sits about 24-30 inches above the floor, so clearance is usually fine . Measure your specific model to be sure.
8. What’s the warranty on these fridges?
- Setpower: 1-2 years (varies by seller)
- Iceco: 2 years
- Dometic: 3-5 years (depending on model)
The Bottom Line
The Kia Carnival is already a fantastic platform for family adventures. Add a 36L portable fridge, and you’ve transformed it into a self-sufficient travel machine capable of extended trips without relying on ice or convenience stores.
For most Carnival owners, the Setpower PT35 offers the best balance of verified capacity, affordability, and features . If you need freezer capabilities, the Iceco GO20 dual-zone is worth the premium . And if you’re the type who buys once and keeps it forever, the Dometic CFX3 35 is the gold standard.
Whichever you choose, you’ll wonder how you ever managed with a traditional cooler. No more soggy sandwiches. No more warm drinks. No more ice runs. Just cold, reliable refrigeration wherever your Carnival takes you.
Kia has moved past just being a value brand. The Carnival proves they understand how families actually live—with all the seats up most of the time, but needing that cargo space to magically appear when adventure calls. A portable fridge completes the picture.
