Car Cup Holder Expander, Adjustable Expandable Insert Extender, Automotive Adapter Holds Hydro-Flask, Yeti, Nalgene, Large (32 40 oz) Water Bottles, Big Drinks - Universal Auto Vehicle (Gray)

I was skeptical of this product (wasn’t familiar with the brand) but I drink out of the 40 oz. Owala bottle on a daily basis and didn’t want it rolling around my car; I wanted to have it in reaching distance at all times. My Owala fits perfectly in this cup holder, and it is so easy to lock the holder into place (and take it out if needed). For me, and for anyone with beverages that don’t fit in traditional car cup holders, this is exactly right!

I am someone who must always have a water bottle with me- and my favorite ones never fit in my holders. This is life changing. Well made and very sturdy. Doesn’t have any logos on the outside so it fits seamlessly in my car interior. Can’t believe I went so long without it.

I was suggested to buy this from my mother in law to expand the cup holders so that I could buy my exercise water bottle in my care without it flying around. Bought it and it’s great I highly recommend you get it. It is easy to use, the grip strength is great for the water bottles, it is extremely stabile and sturdy. And is is worth the money you pay for it. Highly Recommend it.

Got this for my new 2026 Tesla Model Y so I could fit my 40oz Owala. The bottle fits great, no issues there. The fitting feels very secure. However, the standard base is too short for the ‘26 Model Y. I would recommend getting the long base version so it clears the storage bin covers. Also, the width of the piece infringes on the other cup holder, rendering it useless except for maybe jamming a plastic water bottle in it. There’s nothing wrong with the unit but if you have the same car you might want to look for a different option.

My giant insulated Yeti mug that contains everything I hold dear (mostly coffee) fits in the holder. Was pretty easy to install and will be easy to remove. Didn't damage anything. I'm happy with it.

I did a LOT of comparison shopping. This is the one. I bought the first, and ordered another one like two days later. I like that the logo isn't excessive. It's matte black and doesn't look cheap. It really WAS easy to install. Like 10 seconds. Even if you're not mechanical, it's foolproof. It doesn't budge. The option of offset (just an inch or so off of center) helps fit multiples if they are side by side. (I have a 2018 Honda CRV). Fits 40 oz. Hydroflask.

The Swigzy Car Cup Holder Expander Adapter stands out for its thoughtful design and versatility. Its adjustable base and secure grip make it a reliable choice for drivers who frequently use large water bottles or travel mugs. While it may be priced higher than some alternatives, its build quality and user-friendly features justify the investment for many.

Been looking for the perfect water bottle and can holder. THIS IS IT! Adjusts to your cars specific holder and once secured does not fall over. Thank You!
