If you’re looking for a small and portable refrigerator, the BougeRV CRH series is a good candidate.
I felt that the 9L model is particularly suitable for uses such as “I want to chill drinks in the car” and “I want to refrigerate some food for camping.”

- Lightweight at approximately 8.8kg, making it easy to carry with one hand
- Easy to place in the limited space of a car
- Wide temperature setting range of -20°C to +20°C
- Rapid cooling performance, reaching 0°C in approximately 20 minutes
- Supports a 173Wh detachable battery
- Compatible with AC/DC, car, and solar power supplies
- Easy operation with panel and app
- Quiet operation at 45dB or less, making it less noticeable at night
- Limited storage capacity at 9L
- 2L PET bottles cannot be placed upright
- Those who want to thoroughly chill drinks in their car or occasionally use the freezer
- Those who want a small refrigerator that is “easy to place” for solo or duo camping

Ms. GadgetIs 9L enough?
Mr. GadgetYou can fit about ten 350ml cans, and several 500ml PET bottles. It’s difficult to put a 2L PET bottle upright.

Portability and Setup




The strength of this refrigerator is its lightweight design that makes it easy to carry and its tall and space-saving shape. It’s easy to place in limited spaces such as between car seats or at your feet.
- Lightweight at approximately 8.8kg, making it easy to carry with one hand
- Has a cup holder on the top for placing drinks

Ms. GadgetWill it get in the way if I put it in the back seat?
Mr. GadgetIt has a vertical layout so it’s easy to put at your feet, but it may feel a bit large in a kei car.
Cooling Performance
The CRH 9L can be set to a temperature range of -20°C to +20°C, allowing you to not only chill drinks but also store frozen foods. In particular, the rapid cooling performance is excellent, reaching 0°C in approximately 20 minutes in a 32°C environment, according to the manufacturer.
| Merits | Demerits |
|---|---|
| Drinks and snacks can be cooled quickly Also supports freezing, making it versatile | May take time to cool down completely in the heat of summer Cooling efficiency is affected by content and placement |
Mr. GadgetI actually verified it and got pretty much the same numbers!
In the verification, it reached -16 degrees after an hour!
Ms. GadgetThat’s amazing!
Actual Verification Data





- Rapid cooling in quick cooling mode
- Eco mode balances quietness and power saving
Power and Battery Operation


A major feature of this model is that it supports a 173Wh detachable battery.
You can continue to maintain the temperature inside the refrigerator with battery power even after turning off the car engine.
| Merits | Demerits |
|---|---|
| Can maintain temperature even when taken outside the car Effective as an emergency supply during power outages or disasters | Long-term operation with the battery alone is difficult (approximately 10 hours is the guideline) Models with batteries are slightly more expensive |
- Compatible with AC100-240V for household use
- Can also be powered from a car cigarette socket
- Supports solar panel charging (within manufacturer’s recommended conditions)
Operability



Operation is simple, using either the LED panel or the dedicated app. The app allows for remote operation within 10m.
- The operation panel of the main unit is intuitive and easy to see
- The app allows you to check and adjust the temperature
- Bluetooth connection is required, and some people may be a little confused until they get used to it
Ms. GadgetIs the app essential?
Mr. GadgetNo. You can operate it perfectly well with the panel, but the app is convenient.
Quietness
The operating noise is 45dB or less, which is similar to that of a quiet office or household refrigerator. It’s quiet enough to sleep through, but the noise is a little louder in rapid cooling mode.
Maintenance and Durability
Because it uses a compressor, its performance and durability are stable.
It’s best to wipe away any condensation and dry the inside to prolong its life.
Summary
Key points of this heading!
9L, just the right size for cars and camping
The BougeRV CRH 9L is a small portable refrigerator/freezer with a 9L capacity that supports temperature settings from -20°C to +20°C and rapid cooling (approximately 20 minutes to 0°C).
Its vertical layout makes it easy to store cans and bottles upright, and its compact size makes it easy to place in limited spaces such as a car (approximately 14 350ml cans can be stored in 9L).
Lightweight at approximately 8.8kg, making it easy to carry, but the capacity is only suitable for drinks and snacks.
It’s difficult to put a 2L PET bottle upright, and it should be noted that it may take time to cool down completely in the heat of summer.
It supports a detachable 173Wh battery (available in some sets) and AC/DC, car, and solar power supplies. A major attraction is that it can maintain the temperature even when the car engine is turned off (approximately “half a day” is a guideline depending on usage conditions). The operating noise is ≤45dB, making it less noticeable at night, and operation is simple with the LED panel/dedicated app.
Eco/quick cooling modes balance power saving and speed. However, cooling efficiency is reduced if you overfill it, so you need to be creative with the content and placement.
Mr. GadgetIt’s great that it’s small and easy to place, but it can also freeze!

On the other hand, if you plan to store food for several days or go camping with a large group, an 18L or larger model is ◎. If you prioritize drinks and space saving, the CRH 9L is a good balance.
