Review: BougeRV CRH 9L Ultra-Compact Portable Fridge

When searching for a compact, highly portable portable refrigerator, the BougeRV CRH series often comes to mind.
I felt that the 9L model, in particular, is well-suited for use cases like “wanting to keep drinks cold inside a car” or “wanting to refrigerate small food items while camping.”

BougeRV CRH 9L Specifications

Let’s first check the official specifications.

This size feels more like a “car-mounted vertical cooler box” than a “small refrigerator.” The key point is that because of its height, it is easy to store cans and bottles upright.

BougeRV CRH 9L Review & Usability

Portability & Setup

The strengths of this refrigerator are its lightweight design that allows it to be carried with one hand and its vertical, space-saving shape. It is designed to be easily placed even in limited spaces, such as between car seats or in the passenger footwell.

• Lightweight at approx. 8.8kg, making it portable with one hand
• Features cup holders on the top surface to place drinks
• Compact, but because of its height, it has a bit of presence when placed in the footwell

Pros	Cons
Space-saving use in cars and camping Easy to carry when moving	Storage capacity is limited to 9L, making it unsuitable for packing a large amount of food

Cooling Performance

The CRH 9L can be set from −20℃ to +20℃, allowing not only for chilling drinks but also for storing frozen foods. Its rapid cooling performance is particularly excellent, dropping to 0℃ in 20 minutes even in a 32℃ environment, according to the manufacturer.

Pros	Cons
Quickly cools beverages and light meals Supports freezing, offering wide versatility	Takes time to cool down fully in midsummer car interiors Cooling efficiency is affected by content volume and arrangement

• Thoroughly cools in rapid cooling mode
• Achieves both quietness and power saving in eco mode

Power & Battery Operation

A major feature of this model is its compatibility with a 173Wh detachable battery.
Even after turning off the car engine, you can maintain the internal temperature using battery power.

Pros	Cons
Maintains temperature even when carried outside the car Also effective as an emergency backup during power outages or disasters	Long-term operation on battery alone is difficult (approx. 10 hours guideline) Models with a battery are priced slightly higher

• Supports household use with AC 100–240V
• Can also be powered from a car cigarette lighter socket
• Supports solar panel charging (within manufacturer-recommended conditions)

Operability

Operation is simple and can be done via the LED panel or the dedicated app. The app allows remote operation within a 10m range.

• The unit’s control panel is intuitive and easy to read
• The app allows temperature checking and adjustment
• Requires Bluetooth connection, which may take some getting used to for some people

Quietness

Operating noise is 45dB or less, a volume similar to a quiet office or household refrigerator. It’s quiet enough to sleep through at night or during car camping, though the noise increases slightly during rapid cooling mode.

Maintenance & Durability

Because it uses a compressor system, performance and durability are stable.
Wiping away condensation water and drying the interior after use will help it last longer.

Summary

Just the right 9L for cars and camping

The BougeRV CRH 9L is a compact portable refrigerator/freezer that supports temperature settings from −20 to +20℃ and rapid cooling (reaching 0℃ in about 20 minutes).
Its vertical layout makes it easy to store cans and bottles upright, and its size allows it to be easily placed between car seats or in the footwell (9L holds about fourteen 350ml cans as a guideline).

While it is lightweight at approx. 8.8kg and easy to carry with one hand, its capacity is strictly “for drinks and light meals.”
Keep in mind that 2L bottles are difficult to put in upright, and it takes time to cool down fully in midsummer car interiors.

It supports detachable 173Wh batteries (available in bundled sets) as well as AC/DC/car/solar power supply. Its appeal lies in its ability to easily maintain temperature even while parked or during a power outage (continuous operation is generally around “just under half a day” depending on usage conditions). Operating noise is ≦45dB, making it unobtrusive during overnight car camping, and operation is simple via the LED panel/dedicated app.

Switching between eco and rapid modes balances power saving and speed. However, overpacking will reduce cooling efficiency, so some ingenuity is required regarding content volume and arrangement.

Recommended for these people

On the other hand, if you require food storage for several days or large-group camping, an 18L or larger model is the way to go. If beverages are your main focus and space-saving is a priority, the CRH 9L is a well-balanced recommendation.
