Best Car Cup Holder Expander Adapters for Your Large Water Bottles and Mugs

Do you ever feel like your car cup holders are just too small? They sure were for me. I could never find a way to fit my Yeti water bottle in them, so I’d have to just set it on the floor and hear it roll around every time I hit a bump. But then I found a solution: a car cup holder expander adapter. These nifty little gadgets fit inside your factory car cup holder and expand to accommodate your giant Yeti, Gatorade, Hydro Flask, Nalgene water bottles and giant coffee mugs too.

We tested all sorts of top car cup holder adapters out there, and our stand out pick was the Swigzy. This large cup holder insert has an extendable base which offers a snug fit for your beverage, and its sturdy construction—as well as the spill-resistant design—keeps your drinks safe no matter the bumps.

How to choose the best cup holder expander

You know you want a large water bottle cup holder expander. Now you’re wondering how to choose the best one for your vehicle. First things first: consider the diameter and depth of your factory car cup holder. If your car’s cup holder is too shallow or narrow, it can be difficult to find a cup holder expander that will fit properly. Luckily, some of the best car cup holder expanders have adjustable heights and extendable bases so they can fit in pretty much any car cup holder.

Once you’ve chosen a size that fits your factory cup holder well, you want to make sure that your car cup holder expander is sturdy and durable. I recommend looking for models made from sturdy ABS plastic or metal material. Also check that you can quickly mount and detach it from the car —you want to be able to remove it from your car quickly and clean it regularly!

What is the standard cup holder size in cars?

This differs from vehicle to vehicle, but on average, a standard cup holder has an overall diameter of 3.15”. The diameter of the cup hole is on average 2.675’’ diameter, while the depth is 2.25”. These dimensions can hardly fit large mugs or water bottles, hence the need for car cup holder insert adapters.

What do you do if your car cup holder is too small or too big?

Have you ever tried to fit a cup or mug into your car cup holder, only to find that it’s either too small or too big? If so, you’re not alone. While the standard size for a car cup holder is 3.5 inches, the actual sizes can vary from 3 to 5 inches depending on the manufacturer and model. That means your favorite travel mug may not fit in your car cup holder at all!

The solution: an adjustable car cup holder expander adapter. With this product, you can adjust the base of the adapter to fit any size car cup holder. The top part of of the adapter can be used to hold large water bottles, even if the base is compact enough to fit into smaller car cup holders​. And on the rare occasion that you carry a small water bottle, the best car cup holder expander adapters have rubber tabs at the top to snugly hold your bottles or mugs.

Types of Car Cup Holders Expanders Adapters

There are many types of car cup holders for large bottles and mugs, but the most common type is console cup adapter. These expanders fit in your console cup holder then expand at the top to fit large bottles or mugs. However, there are other types of car cup holders for large bottles and mugs that fit in other parts of the car such as side pocket consoles, ledge expanders and even rotating expanders.

For instance, this side pocket console squeezes between your center console and your car seat. Its two cup holders can fit both large and small bottles and cans. Then there is the Ledge cup holder car expander that slots into the gap between your car door and the window. However, if you are looking for a Yeti cup holder or a hydro flask cup holder, the console option might be the best fit for you.

And if you’re looking for a simple way to add more cup holders to your vehicle, there are car cup expanders for that too! Like this innovative Paper Crane cup holder expander that rotates out to hold up to four cups at a time.
