What reviewers say
JOYTUTUS Car Cup Holder Expander Adapter
Owners generally find it does the job of holding large bottles steady in small cup holders, and the adjustable tabs are the most-praised feature. Complaints center on fit in unusually shaped cup holders and on the plastic build feeling basic.
- Holds 32 oz and 40 oz bottles securely
- Rubber tabs adapt to different bottle sizes
- Easy to install and remove
- Cheap fix for undersized cup holders
- Loose fit in some non-round cup holders
- Plastic feels light
- Tall profile can block adjacent cup holders
Questions and answers
- Which one fits a 40 oz Stanley tumbler?
- Both list 40 oz in range. The JOYTUTUS covers 3"-3.8" bottle diameters; the TYKOR covers 2.7"-4.2", so it has more margin if your tumbler is on the wide side.
- Which is better for a 46 oz bottle?
- The TYKOR. It lists up to 46 oz and 4.2" diameter. The JOYTUTUS tops out at 40 oz and 3.8".
- Is the TYKOR worth it over the JOYTUTUS?
- Yes for most shoppers. It is $5 cheaper and fits a wider range of bottles and cup holders. Pick the JOYTUTUS only if you want the rubber-tab grip or the better-known brand.
- Which holds up better over time?
- Neither maker publishes a durability rating. The JOYTUTUS has removable rubber tabs that can wear or be replaced; the TYKOR relies on an expanding base, which is a simpler mechanism with fewer parts to lose.
- Will either fit a small car cup holder?
- The TYKOR's base compresses to 2.6", so it fits tighter holders. The JOYTUTUS needs a holder of at least 2.75".
- Which is easier to clean?
- The JOYTUTUS has removable rubber tabs, so you can pull them out and rinse the body. The TYKOR's expanding base is not listed as removable, so cleaning is wipe-only.
