Car Cup Holder Expander Adapter for Large Water Bottles - [Patented & Upgraded] - Holds: Hydro-Flask, Yeti, Nalgene, Owala, 32-40oz - Adjustable Expandable Insert Extender - Universal

I purchased the Swigzy Car Cup Holder Expander Adapter to use on my zero-turn mower and my John Deere tractor, and it works great. The expanding base fits securely in the factory cup holders and stays firmly in place, even with vibration and rough terrain. It easily holds larger insulated bottles and tumblers that would not normally fit. The build quality feels durable and well made. Very practical accessory and definitely worth the purchase.

I bought my first Swigzy August 2025. It’s sturdy and still in perfect condition, so I’m back eight months later for a second one for me, plus another for gifting. Two fit perfectly in my front seat cupholders (2021 Toyota Highlander Hybrid), can hold 2 40-oz water bottles. They’re super simple to assemble, and tall enough that large drinks won’t tip. I also like supporting small businesses when possible!

I hated taking my 40 oz Owala anywhere in the car, because I never had a place to keep it. This holder is awesome! The base and cup holder are two pieces that you EASILY screw together, aligned to your car. It can be off center (so it doesn't overlap another cup holder) or center if your holders are spaced far enough apart. Mine is centered. A liner for the cup holder part and an Allen wrench are included. It literally took me seconds to screw together. It fits my car perfectly, holds the filled Owala water bottle without any movement and looks nice in my center console area. It tightens easily in your car holder with a twist of the top. Little sponge lined tabs pop out and tighten it just perfect in the holder. It was a little more $$ than others, but it's very well made, right here in the USA. I don't know why I waited so long to get this!

Pro: Large mugs, mason jars, etc fit well and stay in tact, snug in the cup holder Con: Clicking noise as you drive due to the two piece - extremely annoying You have to take it out if you have a soda can, etc. (not adjustable grip)

There’s something so satisfying about searching for a product that meets a need and finding it! It really is that simple, and I’m happy that I found this. I have driven a Subaru, for a decade now, and I enjoy my Subie more than any other vehicle that I’ve owned, as it checks the boxes I had and has held up as promised. The problem? Terrible cupholders! They are incapable of accommodating the Gulp-sized, route 44 diet drink from sonic. The drinks fit into the short holder, but will unseat with any braking at all, spilling the contents all over the gear shift predominantly. This gem gives me the deeper drink holding capacity that *should* come standard on any car sold in America. My needs are simple, I don’t ask much of a cup holder. I don’t have a plethora of drinks that I carry on a regular basis. The holder only needs to be deep enough and wide enough to successfully hold any drink that I might buy while traveling on the road. The Swigzy goes a step further by being designed to meet the many needs of any kind of driver. There is even a nice open strip running down it to allow for drinks with handles. My only concern when considering purchasing this was how well it would actually grip my original cup holder. The smart design also answers this concern by providing enough contact points to even distribute force all around the circumference, and thereby not allowing for poor contact or slippage. Great product, I’ll be buying them as Christmas gifts for my Subie owning family with the same complaint!

I bought two for my RAV4. We use 40 oz tumblers with handles, and this worked fine, except I chose to use just one of the Swigzy Car Cup Holders for the passenger side and also chose to use the existing RAV4 cup holder on the driver's side. It seems to work better. Being able to adjust and swivel the holder to one side allows me to have my 40 oz tumbler sitting lower and I can move the gear shifter a little easier. Very sturdy and durable.

5 stars due to its functionality. It snugged right in the cup holder of a 2014 camaro allowing for more flexibility to hold bigger cups/bottles. My only "complaint" would be that it's very bulky. Not too sure what I expected considering it's made to hold bigger cups/bottles, just didn't really expect it to be so robust/bulky. I guess that's a good thing. It holds any water bottle that we own with no issues. Even has a slot on the side for the coffee mug handle to stick out. I do recommend this product.
