Coolers, Electric Fridges & Food Preservation
Cold storage is where camping, overlanding, fishing, RV life, and outage readiness all shake hands. Two technologies, one decision: rotomolded ice chests that hold temperature for days with no power, and 12V compressor fridges that hold it forever with a battery. This hub teaches the decision, then the sizing.
The decision
Start with the comparison

Electric Fridge vs. Rotomolded Cooler
Cost per trip, power draw math, ice logistics, failure modes — the honest comparison, including when the $60 cooler from the hardware store is the right answer.

Run a Fridge Off a Power Station
A 12V fridge draws roughly 350–500Wh a day in warm weather. The sizing guide and calculator show what that means for station size and solar input.

Ice retention claims are marketing; physics is physics
Published "10-day ice" figures assume a pre-chilled cooler, a 2:1 ice-to-content ratio, and a lid that never opens. Real-world planning number for a premium rotomolded cooler in summer: 4–6 days of safe food temps with sensible loading. Load warm cans on day two and every cooler on earth becomes a two-day cooler.
Capacity ratings lie politely
Quarts are measured differently across brands, and wall thickness eats interior space. Practical rule: a 45-quart class cooler serves 2–3 people for a long weekend of food and drink; 65-quart class for a family or a 4–5 day trip; count a third of the volume as ice.
Electric fridges change the whole trip
No ice runs, no soggy food, set-and-hold temperature, and they sip power (roughly 35–55W cycling). The costs: purchase price, a power source, and a compressor that can fail. For trips over three days and anyone with a power station already, the math favors electric — the comparison page runs it in full.
The unglamorous details decide ownership
Drain plugs that don't leak, latches that work with gloves, tie-down slots that don't block the lid, and a lid gasket that seals. Weight matters too: a loaded 65-quart rotomolded cooler is a two-person lift, which is why the wheeled versions exist.
The lineup we track
YETI Tundra 45
Rotomolded · ~37 qt usable class · bear-resistant rated with locks · ~25 lb empty
List $325
The category benchmark: construction quality, warranty (5 years), and resale value are the argument. Whether it's worth roughly double a value brand depends on how many days a year it works — the comparison page runs both sides.
Check PriceDometic CFX3 45
12V compressor fridge · 46 L · app control · ~41 lb · runs on station or vehicle
List around $950
The electric-fridge anchor. Dometic doesn't run a direct affiliate program we could verify, so links route through retailers — the product earns its place regardless. Deep-cycle protection keeps it from killing a vehicle battery.
Check PriceRTIC 52 Ultra-Light
Rotomolded · 52 qt class · notably lighter than rivals · ~21 lb empty
Around $200–$250
The value pick that embarrasses premium brands on weight and price. Ice retention in owner reports runs close to the big names; the warranty is shorter (1 year). When the cheaper one wins, it wins — this is that cooler.
