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

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!

Update: Reached out to their customer service and they sent me an extra spacer! It now fits perfect! 10/10 recommend. Keeping it at 4 stars only because I wish it was an option instead of having to ask for an extra spacer. The only expander I found that is deep enough for my RAV4… but it’s still a little too short. If I could get one extra spacer, I think it would be perfect. I haven’t tried it while driving yet, but it seems sturdy when I wobble it around. Will update later to see how well it is.

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!

Fantastic! Works great in my 2026 Transit 250 van. Used offset mode. Couldn't spin it around to tighten so had to put it in when it was almost tight and give it a small turn and it's nice and snug. Ordered a second for the other cup holder!

It works nicely so far. It fit my cup holder and holds my owala perfectly. I was so tired of my cup rolling around on the floor or seat. This fixed that problem. Seems good quality

Went through about a dozen different design oversized cup holder adapters for my SUV and pickup in the last two years and all had problems ranging from just plain cheap/flimsy materials to unstable to not fitting as described. Bought two of these Swigzys on a hunch after looking carefully at the photos and description. They work great. Easy install, and easy removal. Your 9 year old could do it. They can even be positioned offset, with a simple screw change, from center if your vehicle requires that to clear a console shifter or an adjacent cup holder. The rubber tabs inside the cup holder section are WAY better than the many competitors as they do not pull out and they leave no gaps in coverage. AND you do NOT have to remove any of them to fit various cups and bottles like you do with many others. Everything I’ve put in them from 20 oz bare Diet Coke bottles to the larger Yetis to a big coffee mug with handle fit in and out easily and was retained well with no loosening or vibration. They’re even useable with the smaller 16oz Coke bottles and 12 oz cans with only minimal movement thanks to the rubber tabs design. Put a koozie on either of those and get zero movement. They are big to hold big things, so no problem with my full size vehicles, but if you have a tiny car chances are excellent you can still use them because of their adjustment position variables and design. The acid test for approval was my wife of 49 years is thrilled with them, and no longer has to worry about spills or a less well designed cup holder coming loose when she lifts her cup or mug.

This cup/bottle holder is exactly as described and I’m in agreement with the great majority of the reviews. I have a Skoda Yeti and the inbuilt cup holders aren’t really fit for purpose. This bottle/cup holder just about squeezed into the original cup/bottle holder space, therefore I didn’t need to make any adjustments to the base to make it a snug fit. It holds my largest drink bottles very securely. I did however have an issue with my original order. I placed my order 08/02/26 to be informed of a 24/03/26 delivery, this was then updated to 23/08/26!!!! Ridiculous to have to wait half a year!! I then cancelled the order, went back onto Amazon site and placed the order again (the price of the item had risen by this point). This time the item arrived in a matter of days and in fact was delivered a day prior to the date which I had been given upon which day/date to expect delivery. All in all a bit of a bumpy ride with the delivery saga, but very pleased with the product.

I was sceptical with this at first but on arrival it fit the oversized yeti flask perfectly the design and build quality is flawless. It also fits standard size coffee cups etc with the way it is designed. Fits in very sturdy. Still can put another cup next to in in the dual cup holder bay in Mazda CX5. Best birthday present for my wife she loves it!

Tal cual lo que necesitaba. Lo recomiendo mucho.

Produkt war zwar an sich gut. Konnte meinen großen 1 Liter Trinkbecher gut reinstellen. Ich mochte die Funktion mit der man es im eigentlichen Getränkehalter fest arrentieren konnte. Leider passte es mit den Maßen nicht in mein Auto, da ich dadurch nicht mehr ordentlich Schalten konnte und es sich dadurch um eine Gefährdung handelt. Ich einen alten Dacia Sandero. In größeren Autos bei denen mehr Platz zwischen Schaltknauf und Getränkehalter ist kann es sicherlich gut funktionieren.

Love this!! Holds my frank green !!!
