A week of food lives at 0°C (32°F). Nothing lives on ice.
Ice melts.
Gel packs and Frio pouches drift out of range hours before you notice.
Cars get hot.
A parked car in summer can hit 60 °C. Most carriers can't keep up.
Hotel fridges fail.
Mini-bars freeze pens or run warm. There's no way to know without a thermometer.
The five numbers that matter.

Quieter than most mini fridges

Under 1 kWh per day
Built around four road trip anxieties.
Won't stop cooling in summer heat
Compressor cooling works in ambient temps up to 110°F — no performance loss when your car is parked in the sun. Unlike thermoelectric units, it doesn't depend on outside temperature.
Won't drain your car battery
Three-level battery protection (High / Medium / Low) monitors your vehicle's voltage and cuts power before you're stranded. Set it to Medium for everyday car use.
Won't keep you up at night
45 dB operation. Quieter than a standard hotel mini-fridge. Run it overnight in the back seat without losing a minute of sleep.
Fridge or freezer — your call
Dial anywhere from -4°F to 68°F. Freeze meat for a week-long trip or keep drinks at 38°F. One dial, one unit, no compromises.
Three steps. Then forget about it.
1
Plug in.
Connect to your car's 12V socket, a 100–240V wall outlet, or your RV hookup. The ZKSCool 37QT switches between all three automatically.
2
Set your temperature.
Touch the LED control panel to dial your exact target. Switch between ECO mode (36W) for efficiency or MAX mode for the fastest cooldown.
3
Load and go.
The 37QT cavity fits a full week of food for two. The anti-vibration design keeps everything stable on rough roads, even at a 45° tilt.
What it's built to hold.
37 quarts. Here's what that actually means.
20 frozen tuna steaks
Vacuum-sealed portions stacked flat. Stays frozen at -4°F the whole trip.
10 cartons of milk
Full quart-size cartons. Enough dairy for a week on the road for two.
Other temperature-sensitive meds
Or swap for beer, soda, or sports drinks. 50 standard cans fit comfortably.
Why not just an ice pack?
1
Ice Chests
Melts in hours. Wet food, soggy bags, and a gas station ice run every day.
2
Thermoelectric cooler
Cools only 40°F below outside temp. Useless on a hot summer day when you need it most.
3
Other compressor fridge
Loud, power-hungry, and no battery protection — your car won't start in the morning.
4
ZKSCool
-4°F to 68°F. Silent at 45dB. 36W ECO. 3-level battery protection. Actually works.
Questions worth answering.
If we missed yours, send us a note.
-
Internal usable space holds8 injection pens, 48 cartridge refills, or 15 insulin vialsin any combination. Customers regularly carry Lantus, Tresiba, NovoLog, Humalog, Ozempic, Wegovy, and Mounjarowithout modification.
-
8–12 hours on a full charge at typical room temperature. Extreme heat or cold will reduce runtime. You can also run it plugged in.
-
Yes — TSA and most international authorities allow medical cooling devices in carry-on. The lithium battery is under the 100 Wh limit. Bring your prescription or doctor's note to be safe.
-
No — the thermostat holds 2–8 °C and will not drop below freezing. The app lets you set custom thresholds and will alert you if temperature drifts.
-
No — it works for any temperature-sensitive medication: GLP-1s, biologics, growth hormone, fertility meds, etc. Check your drug's storage range and set the app accordingly.
-
1 year from purchase, covering defects in materials and workmanship. Accidental damage and normal wear are not covered. Extended plans available at checkout.
-
The unit has a built-in sensor and an LCD on the front. Pair it to the ZKSCool app over Bluetooth for a 24-hour temperature chart and custom alert thresholds. iOS App Store live; Android rolling out. The cooler works fully without the app.
-
No it does not. USB is not strong enough to power cooling effectively. We recommend to bring multiple packs of batteries if needed.
-
Yes — the lid and the fan cover are both detachable and washable. No biofilm traps, no condensation pooling.
-
15–20 minutes from room temperature to 5 °C, depending on how full it is. Plug it in 15 minutes before you load your medication.
-
The aviation-aluminum and polyurethane insulation hold residual cold for 2–4 hours. The app and the device alarm before that point so you have time to plug in or swap to a backup battery.
-
No — it's a precision instrument with a fan and electronics. Don't submerge it. The detachable lid is washable separately.
