★★★★★
I used to wedge my bottle between the seat and the console and pray. The expander took two seconds to set and the phone pocket on the side is where my badge lives now.
Expander + Phone Pocket★★★★★
The tray swings toward the passenger seat when I don't need it and back when I do. Salad, drink and phone all on one post while I sit in a parking lot between calls.
9.5″ Swivel Food Tray★★★★★
Every other adapter I tried was either too loose or too tight for the handle. The arms dial right out to the width I need and the knob stays put.
Adjustable Arms Expander★★★★★
Vent clips kept sagging in my car. This mount sits in the cup holder, still holds a bottle, and the arm bends exactly where I want the map.
2 in 1 Phone Mount★★★★★
One in the front holder, one in the back door pocket. The lid snaps shut on its own, so no smell from the half-eaten snacks my kids leave behind.
Cup Holder Trash Can, 2 Pack★★★★★
My truck has two holders and I needed three. The double expander gives me a big bottle on top and a spot for the thermos right beside it.

Most car cup holders were drawn up for a 12 oz can, while the bottles people actually carry now run 32, 40 and even 64 oz. A cup holder expander sits in the original holder and gives you a wider, deeper ring on top. DYLEN expanders use a base that spreads out with a twist, so the adapter locks into round holders from about 2.5 to 3.9 inches across and stays in place when you lift the bottle out.
We size our rings and arms around the drinkware you already own: 20 to 46 oz tumblers and flasks in the fixed-ring models, and anything from 2.5 to 5.9 inches wide in the adjustable-arm expander. A slot in the side lets a mug handle pass through, and rubber tabs keep narrower bottles centered instead of rattling.
The same base that holds a bottle can carry a swiveling food tray, a phone mount on a bendable arm or a small lidded trash can. Each one uses the cup holder as a sturdy anchor, so you can eat, navigate and clean up without clips on the vents or adhesive on the dash.
Measure the inside of your cup holder and the widest point of your bottle. Round holders work best; square, shallow or covered holders may not give the base enough grip. Our fit guide walks through the measurements in a couple of minutes.
