【3COINS】The lukewarm latte problem while driving! I tested the performance of the insulated tumbler and surprisingly it's good

Is there a way to enjoy a cold iced latte until the end during a summer drive? This time, I challenged myself with the 3COINS insulated tumbler with a car lid, comparing it with a regular plastic cup and measuring the temperature. Will this change the quality of the drive?

The lukewarm latte caused by the traffic jam is subtly stressful; I want to do something about it

Many people likely have such simple pleasures as a weekend drive, school pick-ups, and stopping by a convenience store to buy an iced latte...

However, after returning to the car for a while, the crucial latte has already become lukewarm. When the ice melts and the taste becomes diluted, a slight disappointment accumulates, making the travel time feel bland. Especially in midsummer, the temperature changes inside the car are significant, and it feels challenging to keep iced drinks delicious for long.

Is the 3COINS insulated tumbler somewhat usable?

So, I used the CAR insulated tumbler with a lid from 3COINS to test how long an iced latte can stay cold.

I also used a plastic cup bought under the same conditions to compare the duration of coldness.

In a car set to 25℃ with air conditioning, I measured the state of the ice and temperature changes every 30 minutes to 1 hour from 10:00 to 14:30.

The plastic cup started to melt ice in 30 minutes, and by 11:30, it was close to room temperature. By the afternoon, the ice had completely melted.

On the other hand, the tumbler with a cooling lid for cars from 3COINS maintained its temperature for 1 hour, 2 hours, and 3 hours. Even at 14:30, there was still plenty of ice left, and it remained cold.

It fits perfectly in the holder! You can quickly take a sip while waiting at the signal.

The iced latte managed to stay somewhat cold. However, the tumbler may not fit depending on the type of vehicle, so how about this point?

Since it has a tapered bottom design, it fit nicely in the genuine drink holder of the Alphard without wobbling and remained stable.

With the handle attached, it's easy to take it out quickly with one hand while waiting at the signal. Not bad.

Since it has a lid, it not only prevents dust but also makes those "casual moments when you want to take a breather during busy mornings or while waiting for kids’ extracurricular activities" comfortable.

When "it stays cold until the last drop," the time spent in the car changes.

What I realized this time was that "the temperature stays perfect for drinking" is more comfortable than I expected. Being able to enjoy iced lattes while they’re still cold until the last sip…it’s just that simple, but it felt like the way I spend my regular drives has become a little richer.

The right level of comfort changes the quality of the drive.

It’s not an expensive item or the latest technology, but "the right level of comfort" is right there. It allows you to enjoy cold drinks while they're still cold, at an easily accessible price, enhancing the quality of time spent in the car. That is the charm of this tumbler. For those who want to focus on that little extra comfort in their daily lives, I think this will definitely be satisfying.
