Integral Truck Mug Integrator™ Expandable Mug Holder

Keep your favorite mug or travel tumbler secure and upright, even on rough roads and jobsite drives, with the Mug Integrator Expandable Mug Holder. This compact, twist-to-adjust insert fits into your vehicle’s cup holder and expands to grip large coffee mugs, YETI, Hydro Flask, RTIC, and other tumbler-style drinkware. Unlike flimsy adapters or magnetized inserts, this mug holder delivers stability during bumpy rides—whether you’re driving trails or hauling gear to the worksite. 

Key Features & Build Quality

• Expanding base (2.5″–3.75″) adjusts with a twist to fit snugly inside most cylindrical cup holders — keeping mugs stable and preventing spills on uneven terrain. 
• Oversize mug compatibility supports coffee mugs and tumblers with a diameter between 3.5″ and 4.0″ — including YETI Ramblers, Hydro Flask-style mugs, and large ceramic camp mugs. 
• Handle slots allow mugs with handles to sit flush in the holder, avoiding interference from adjacent cup holders and keeping your mug upright. 
• Offset and height adjustment options enable placement that leaves room for a second drink or cargo—useful in tight dual cup holder spaces or when fitting in consoles with raised edges.
• Quick, tool-free install—simply insert into your cup holder, twist to expand, and adjust as needed. No adhesives, screws, or permanent hardware required. 

Why This Mug Holder Works for Overlanders & Trades Pros

Overlanding & Trail Use

• Prevents hot coffee, drink mixes, or camp beverages from spilling when shifting gear, driving on gravel roads, or navigating trails.
• Lets you travel with your favorite mug or tumbler instead of transferring beverages into disposable cups—reducing waste and keeping your camp setup more personal.
• Compact enough to stow in a Packout organizer, camper drawer, or console when it’s not needed, keeping your mobile rig tidy.

Contractors, Trades & Mobile Crews

• For workers who spend long hours in a truck—electricians, carpenters, plumbers, or mobile mechanics—this mug holder keeps your coffee or drink stable and within reach during drives, site visits, or travel between jobs.
• The stable design reduces the risk of spills on tools, electronics, or paperwork stored in your console or cab.
• Because it’s removable and doesn’t require permanent installation, this mug holder can be shared between multiple trucks or stored when not needed—ideal for fleet vehicles or lease rigs.

Installation & Use Tips

1. Insert the Mug Integrator into your cup holder.
2. Twist the top portion to expand the base until it fits snugly—this expansion stabilizes the holder and prevents upward movement.
3. Place your mug or tumbler in the center, aligning the handle (if applicable) into one of the dedicated handle slots.
4. If you're using a mug with a tall handle or a lid, adjust the height or offset with the included spacers as needed (these can help with consoles or deep cup holder designs). 
5. When not in use, simply twist the insert to collapse the base and remove it—then store it upright in a console, Packout box, or drawer.
6. If using the insert in a tapered or non-standard cup holder, monitor stability. Some users have reported that sharp tapers or narrow bottoms may cause the insert to lift slightly when tightened.

Final Thoughts

If you’re out on the trail or out on the job and don’t want to compromise your coffee routine, the Mug Integrator Expandable Mug Holder is a simple, smart solution. It enables you to bring your favorite mug, tumbler, or travel cup along without worrying about spills or stability—whether you're navigating rough terrain, hauling gear, or driving between job sites.

Note: This mug holder is designed to fit standard cylindrical cup holders—very tapered or non-standard designs may impact stability. Some console cup holders may benefit from additional spacers or trial fitting.
