How to choose a cooler box for family camping
With such a wide variety of cooler boxes available, you might be wondering which one to buy.
This article explains how to choose a cooler box suitable for a family camping trip with 3-4 people.
Cooler boxes are broadly divided into soft-type and hard-type.
First, let's consider the different types of cooler boxes available.
Cooler boxes can be broadly divided into two types: hard-sided and soft-sided.
Hard-type coolers are durable and can be used as tables or chairs, and they also have excellent cooling capabilities.
On the other hand, soft-sided coolers cannot be used as a stand, and their cooling performance is inferior to that of hard-sided coolers.
However, its appeal lies in its compact size and light weight, which allows it to be folded up when not in use.
For a family, a hard-type mattress as the main one and a soft-type mattress as a backup should be sufficient.
If compactness is your priority, choose the soft type.

For short outings or day trips where you don't need to carry much luggage, a compact, soft-sided suitcase is ideal.
Although I mentioned that soft-type coolers have inferior heat retention compared to hard-type coolers, you can extend the cooling time even with soft-type coolers by freezing drinks such as plastic bottles or cans before putting them inside.
If you prioritize high cooling performance and versatility, choose a hard-shell type.

Box-type cooler boxes have excellent cooling capabilities and can keep contents cool for extended periods.
Cooler boxes made from materials with high cooling capabilities, such as vacuum-insulated panels or polyurethane, are recommended.
Styrofoam cooler boxes are relatively inexpensive, but be aware that their cooling performance is somewhat inferior.
It's important to choose a cooler box with the appropriate cooling capacity based on the duration of your camping trip and the temperature.
If you're just starting out with camping and haven't decided on a specific scenario for using it, a versatile hard-type tent would be a good choice.
A rough guideline for cooler box capacity is the number of adults multiplied by10L~15Lis.
3~4At someone's family camping trip1If you are bringing enough food and drinks for a day,30QT~40QT(28L~38LThis will give you an idea of the appropriate capacity.
However, this will vary depending on the length of your camping trip and the amount of food you bring, so it's best to choose with some leeway.
If convenience is your priority, choose a hard-type bag with wheels.

Ease of carrying
Since cooler boxes become heavy when filled, ease of transport is also an important selection criterion.
A cooler box with wheels is convenient to transport on flat ground.
If you're bringing a lot of drinks like beer and juice, a hard-shell suitcase with wheels is ideal.
It's easy to carry even if the parking lot is far from the campsite.
For a family of 3-4 people, a capacity of 30L or more is a good guideline, so it's best to choose one with a capacity of 30 liters or more.
A 30-liter cooler is too small to hold enough food for the whole family, so if you want to carry more drinks and other items, choose a larger size (40-50 liters) or consider using a soft-sided cooler in conjunction with it.
I also check things like how easy the handles are to grip and whether or not there's a shoulder strap.
Choose a cooler box that is easy to carry, taking into account the campsite environment and your mode of transportation.
Hard-type coolers offer superior cooling performance.
Hard-type coolers are overwhelmingly superior in terms of cooling power.
However, it's pointless if you don't pay attention to the environment in which you use it.
Specifically, please pay attention to the following:
- Put in something that has been chilled beforehand.
- Freeze anything that can be frozen.
- Do not place it in direct sunlight (place it under a tarp, etc.).
- Do not place it directly on the ground (place it on a chair or something similar, even if it's just a temporary surface).
Ease of opening and closing
The method for opening the cooler box lid varies depending on the model.
Choosing a cooler box that is easy to open and close will make it more convenient to use while camping.
A cooler box that can be opened and closed with one hand is convenient and highly recommended.
Also, cooler boxes with a double-opening design are convenient because they can be opened from either side.
Ease of use as a stand
For family camping trips, using a cooler box as a stand is also a convenient option.
Hard-shell cooler boxes, in particular, can be used to store food and prepared meals.
When using it as a stand, having a raised edge on top of the cooler box provides peace of mind because it prevents items placed on it from sliding or falling.
Also, pay attention to the height and weight capacity.
Choosing a cooler box with sufficient strength will ensure comfortable use.
[Beginner] Recommended cooler boxes for family camping trips with 3-4 people
This article introduces recommended cooler boxes for family camping trips with 3-4 people, divided into soft-sided and hard-sided types.

It can hold approximately 20 500ml plastic bottles or 6 2L plastic bottles.
However, perhaps due to the nature of soft-sided coolers, or perhaps because of their high cooling capacity, condensation can sometimes form.
Conversely, the fact that it achieves such cooling power that condensation occurs in a product of this size is a noteworthy point.

What are the standards for cooling performance?The number of days that ice placed in a cooler box at a room temperature of around 20°C remains unmelted.This refers to the fact that there are no standards for "cooling performance" in the JIS standards.
However, this is only a guideline, so for longer stays, it's safer to buy perishable items in advance.

Shinwa Holiday Land Cooler 48H (Made in Japan)

source:Amazon
This is a product from a fishing tackle manufacturer.
"What?! Isn't it an outdoor equipment manufacturer?You might think, "Is that all there is to it?", but since its purpose is to transport caught fish while keeping them fresh, its cooling power is guaranteed, and the thickness of the insulation material is about 30 mm, which is three times that of other manufacturers.
Since it's designed for fishing, the lid buckle is made of stainless steel.

Tips for improving the cooling performance of your cooler box.
The cooling performance of a cooler box varies greatly depending on how it is used.
By incorporating the following tips, you can improve the cooling performance of your cooler, so be sure to remember them.
- Pre-cool before use.
- Insert an ice pack.
- The stand will prevent geothermal heat
- Place in the shade
- Divide the cooler box into two
Since cold air escapes every time you open and close a cooler box, it's recommended to use two cooler boxes if you're bringing a large amount of food or drinks.
Also, pre-cooling the cooler box with ice packs before taking it with you will help maintain its cooling effect for longer.
Placing the cooler box on a stand is also effective in preventing it from getting warm from the heat of the ground.
Furthermore, placing the cooler box in the shade to avoid direct sunlight will prevent its temperature from rising.
By combining these techniques, you can maximize the cooling power of your cooler box and keep your food and drinks fresh for longer during your camping trip.
summary
For family camping trips with 3-4 people, a cooler box with a capacity of around 28L to 38L is recommended.
Depending on your needs, you might also want to prepare an additional small cooler bag.
Cooler boxes are multi-functional camping items that not only keep food and drinks cool, but can also be used as storage space and a stand.
When heading out on a family camping trip, choose the perfect cooler box to ensure a fun outdoor experience.
