## Batteries & power stations
[Guide →](https://portablefridgeguide.com/posts/how-to-power-a-portable-fridge/)
What runs the fridge when the engine is off. Lithium (LiFePO4) gives you nearly all its rated capacity; lead-acid only about half.

- Battery & power**Anker SOLIX EverFrost 2 Removable Battery (288Wh)**Official AnkerA second 288 Wh LiFePO4 pack doubles the EverFrost 2's cordless runtime (Anker claims up to 104 h on the 40L) and doubles as a USB-C power bank. Fits: [EverFrost 2 40L](https://portablefridgeguide.com/fridges/anker-everfrost-2-40/).[Check price](https://www.amazon.com/dp/B0DRFX1YDD?tag=portablefridgeguide.com-20)
- Battery & power**EcoFlow 298Wh Plug-in Battery for GLACIER Classic**Official EcoFlowThe Glacier Classic's own battery: a spare for longer trips, or the add-on if you bought the cheaper no-battery version. Fits: [Glacier Classic 35L](https://portablefridgeguide.com/fridges/ecoflow-glacier-classic-35/).[Check price](https://www.amazon.com/dp/B0F4DZQ8QM?tag=portablefridgeguide.com-20)
- Battery & power**ICECO PB250 Magnetic Power Bank (250Wh)**Official ICECOICECO's magnetic 250 Wh pack, which ICECO names as the cordless option for the GO20. It sticks to the fridge and also charges phones. Fits: [GO20](https://portablefridgeguide.com/fridges/iceco-go20/), [VL45 ProS](https://portablefridgeguide.com/fridges/iceco-vl45-pros/), [VL60 Dual Zone](https://portablefridgeguide.com/fridges/iceco-vl60-dual-zone/), [VL75 ProD](https://portablefridgeguide.com/fridges/iceco-vl75-prod/). Fine for a small GO20; on the larger VL fridges expect hours rather than days of runtime.[Check price](https://www.amazon.com/dp/B096KJS4MN?tag=portablefridgeguide.com-20)
- Battery & power**Anker SOLIX C300 DC Power Station (288Wh)**Universal fitA budget DC-only power bank with a 12 V car socket. It keeps a small compressor fridge running overnight while the engine is off.[Check price](https://www.amazon.com/dp/B0D62PMB3R?tag=portablefridgeguide.com-20)
- Battery & power**EcoFlow RIVER 3 Plus Portable Power Station (286Wh)**Universal fitA compact power station with a 12 V car outlet, enough for a night or two on a small fridge. It recharges from the car or solar during the day.[Check price](https://www.amazon.com/dp/B0DCCB657J?tag=portablefridgeguide.com-20)
- Battery & power**LiTime 12V 100Ah LiFePO4 Battery (Group 31)**Universal fitAbout 1,280 Wh of lithium storage, enough to run an efficient 45-quart fridge for several days.

## Solar panels
[Guide →](https://portablefridgeguide.com/posts/solar-panel-size-for-12v-fridge/)
Folding and rigid panels that put back what the fridge uses each day. Size them with the runtime calculator.

- Solar**EcoFlow 220W Bifacial Portable Solar Panel**Universal fitA bifacial panel that plugs straight into EcoFlow RIVER and DELTA power stations. It is a good match if your fridge runs from an EcoFlow.[Check price](https://www.amazon.com/dp/B09TKM8PBQ?tag=portablefridgeguide.com-20)
- Solar**FlexSolar 100W Portable Solar Panel**Universal fitA 100 W foldable panel sized for the built-in solar inputs on the Anker EverFrost 2 (100 W max), EcoFlow Glacier Classic (110 W) and BougeRV CRD2 (150 W).

## 12V wiring & monitoring

Cigarette sockets are the weak link in most setups. Better plugs, heavier cables and a battery monitor fix most "my fridge keeps shutting off" problems.

- Monitoring**AcuRite Wireless Fridge & Freezer Thermometer**Universal fitAn independent check on the fridge's own display, which owners and testers often find a few degrees off, with a high-temperature alarm and max/min memory.[Check price](https://www.amazon.com/dp/B004QJVU78?tag=portablefridgeguide.com-20)
- 12V wiring**Anderson Power Products SB50 Connector Kit (6 AWG)**Universal fitThe standard overlanding connector for a fused, high-current fridge circuit. It is far more secure than a cigarette-lighter plug on washboard roads.[Check price](https://www.amazon.com/dp/B07CHBKS6K?tag=portablefridgeguide.com-20)
- 12V wiring**26 ft 14AWG Heavy-Duty 12V Extension Cord (20A)**Universal fitHeavy 14AWG wire avoids the voltage drop that makes fridges trip their low-battery cut-off when run from the front socket to the back of an SUV or truck bed.[Check price](https://www.amazon.com/dp/B0BMPX96JL?tag=portablefridgeguide.com-20)
- 12V wiring**16.4 ft 12V/24V Car Fridge DC Power Cord**Universal fitA longer replacement for the short DC cord most fridges ship with, so the fridge can sit in the cargo area while plugged into a dash socket. Fridge-end plugs differ by brand: confirm the connector matches your model before ordering.[Check price](https://www.amazon.com/dp/B0F2T7XPNQ?tag=portablefridgeguide.com-20)
- 12V wiring**Renogy 12V 20A DC-to-DC Battery Charger**Universal fitCharges a second battery from the alternator while you drive and isolates it from the starter battery, so the fridge can never leave you unable to start the engine.[Check price](https://www.amazon.com/dp/B0DQP87ZRK?tag=portablefridgeguide.com-20)
- Monitoring**Victron SmartShunt 500A Bluetooth Battery Monitor**Universal fitShows real state of charge and how much your fridge is actually drawing, not just voltage, on your phone. It is the best way to size a battery and solar setup.[Check price](https://www.amazon.com/dp/B0BF636VBX?tag=portablefridgeguide.com-20)

## Insulated covers

A fitted cover cuts the compressor's work in hot cars and protects the case. Buy the one made for your exact model and size.

- Insulated cover**BougeRV 23 Quart Insulated Protective Cover (CR22)**Official BougeRVA $40 insulated cover for the 23-quart CR22 that helps it stay cold in a sunny car and may reduce the condensation OutdoorGearLab noted.

- Insulated cover**Dometic CFX 75L Protective Cover**Official DometicThe matching cover for the CFX5 75DZ (also fits the CFX3 75DZ). A dual-zone fridge in a hot truck bed works noticeably less hard with one on. Fits: [CFX5 75DZ](https://portablefridgeguide.com/fridges/dometic-cfx5-75dz/).[Check price](https://www.amazon.com/dp/B0BZGQDW8W?tag=portablefridgeguide.com-20)
- Insulated cover**ICECO Insulated Protective Cover for VL45 ProS**Official ICECOInsulated bag made for the VL45 ProS, with five organizer pockets.

Fits: [GO20](https://portablefridgeguide.com/fridges/iceco-go20/).[Check price](https://www.amazon.com/dp/B09KNCFN58?tag=portablefridgeguide.com-20)

## Mounting & organizing

Slides, tie-downs, baskets and thermometers: the extras that make a fridge easier to live with on the road.

## What you actually need (and what you can skip)
A compressor fridge comes ready to run: a 12V DC cable for the car socket and, on most models, an AC adapter for the wall. If you only plug it in while you drive and at the campsite's outlet, you need nothing else. Accessories start to matter when the engine is off for more than a few hours, the cabin gets hot, or the fridge rides loose in the back of a truck.

## Power first: battery, then solar
The fridge's built-in low-voltage cutoff protects a car's starter battery by switching the fridge off, which keeps you from getting stranded but also lets your food warm up. For overnight stops and longer, a separate battery is the real fix. Lithium iron phosphate (LiFePO4) batteries and portable power stations give you most of their rated capacity, while lead-acid and AGM batteries should only be drained to about half. Our [battery runtime calculator](https://portablefridgeguide.com/tools/battery-runtime-calculator/) shows how many hours a given battery gets you at your temperatures, and how many solar watts replace a day's use. The full walk-through is in [how to power a portable fridge](https://portablefridgeguide.com/posts/how-to-power-a-portable-fridge/).

## Fix the 12V socket before you blame the fridge
Most "fridge keeps shutting off" complaints trace back to voltage drop: thin factory wiring or a loose cigarette-lighter plug lets voltage sag under the compressor's start-up load, and the battery protection trips even though the battery is fine. A heavier-gauge cable, a locking plug (Anderson or an 8 mm DC socket) and keeping the run short usually solves it. A battery monitor tells you what's really happening.

## Covers, slides and tie-downs
An insulated cover is worth it if the fridge sits in a parked car in summer: it reduces how often the compressor cycles and protects the case. Buy the cover made for your exact model and size, since lid hinges and handles differ. In a truck bed or SUV, a slide makes a top-loading fridge usable, and a tie-down kit keeps 50+ lb of fridge and food from becoming a projectile. Still choosing the fridge itself?
