Car Cup Holder Expander — 2-in-1 Adjustable Cup Holder Adapter
Product description
What you get: a single 2-in-1 cup holder expander with an adjustable insert base and a rotatable upper holder. The main parts are molded from durable ABS plastic with a reinforced upper fence for added strength and longevity.
Design and function: the top portion is redesigned to offer better stability and can rotate a full 360°, allowing one cup slot to split into two usable spaces. The lower cup well measures about 3.9" across and is intended to accept large insulated bottles such as 32/40 oz Hydro Flasks, CamelBak 32/40 oz models, Yeti tumblers, Nalgene, Contigo, Tervis and similar wide containers.
Adjustability and fit: the top expanding ring stretches from approximately 3.9" to 5.9", providing room for taller or wider drinkware, phones, or snacks. The base insert expands from roughly 2.6" to 3.35" in diameter so it can be tightened inside most circular center-console cup holders; it’s also suitable for many golf carts, boats, and trucks. Note that holders with pointed or elongated shapes may not accept this insert.
Installation and use: to fit, place the base into your vehicle cup opening and turn the expander so the bottom plate widens and secures the unit in place. Rotate the upper section to split the compartment into two when needed. The reinforced fence around the top ring increases durability and helps keep bottles stable while driving.
Care and support: the thickened upper bracket improves toughness for repeated use. If the unit arrives damaged or has manufacturing defects, contact the retailer for assistance and replacement options.

- Upper section can occasionally loosen over time
VerdictA versatile cup holder insert that converts one cup slot into two and accommodates oversized bottles and tumblers. The ABS construction and reinforced upper fence add rigidity, and the expandable bottom locks into a wide range of console openings. It can rattle when empty and may need a bit of fiddling to seat perfectly in some consoles, but once installed it handles heavy, wide bottles well and i

Great for road trips
Ideal for travel. The upper compartment is handy for snacks.

Does the job — durable so far
I've used this for six months and it's held up well. You may need to lift the top slightly to rotate when a full bottle is in place. The expanding arms grip bottles firmly and it shows little wear. It can rattle when empty and it took a few tries to seat the base in my console; a large 30 oz bottle did pop out once.

Fits 2016 RAV4 perfectly
Bought for my 2016 RAV4 and it fits Stanleys nicely. Hoping it stays solid — will update if anything changes.

Too noisy for me
Plastic parts vibrated and squeaked even on smooth pavement. I couldn't tolerate the noise and returned it.

Game-changing upgrade for tall tumblers
Solved both diameter and reach problems in my RAV4 — raises the drink higher and rotates so it's easier to grab. Great for delivery work; it even held a large Frosty without tipping.

Not as pictured — check specs
Product lacked the adjustable base shown in pictures and had no slot for a mug handle. Overall height was only about 7.2 inches. Do not rely solely on images; check dimensions and return options before buying.

Practical and useful
Bought two units for the family. Lets me bring my coffee into the truck easily. Wish the arm felt a bit steadier, but it works well.

Sturdy and functional
After months of use it restored the lost cupholder space in our minivan. Holds various sizes and weights reliably. Occasionally the bottom screw needs a quick tighten but that's a small gripe for what it delivers.

Hard to align while tightening
Good idea but you have to twist the whole piece to lock it, which makes keeping the cup slots aligned tricky. Once secured it holds my Nalgene and my wife's hot drink fine.

Surprisingly impressive
Adjusts to different cup sizes and the bottom expands to fit odd-shaped holders. Very sturdy — much better than I expected.
