Costco Cell Phone Accessories: 3 Must-Buys & 2 to Avoid! (2026)

Costco may not be the first place you think of for tech accessories, but it's a hidden gem for those in the know. With its membership discounts, it's tempting to grab a bargain without considering the long-term value. So, let's dive into the world of Costco cell phone accessories and uncover some gems and some not-so-great options.

The Good, the Bad, and the Ugly: Unveiling Costco's Cell Phone Accessories

But here's where it gets controversial: not every product on Costco's shelves is a winner. We've scoured the reviews and ratings to bring you the best and the worst of Costco's cell phone accessory offerings.

Buy: Apple AirTags (4-pack)

Do you find yourself constantly misplacing your phone or other small items? It's a common problem, but with Apple AirTags, you can say goodbye to those frustrating moments of searching. These discreet tags can be attached to your phone, wallet, or even slipped into your backpack. With a simple tap on your iPhone's Find My app, you'll be guided right to your lost item. And the best part? It's all done securely and privately, thanks to the Find My network.

The Apple AirTag 4-pack is a top-rated choice, with a near-perfect 4.8 out of 5 rating. One user raved about how it provided peace of mind during travel, instantly locating a misplaced bag and its precise location.

Skip: Aukey MagFusion Magnetic Charging Station

Charging convenience is a must-have these days, but the Aukey MagFusion Magnetic Charging Station falls short of expectations. Designed as a 2-in-1 base and charging station for your smartphone and other devices, it promises a lot but delivers little. Users have reported issues with the suction cup mount and, more importantly, the lack of charging power. Despite the instructions, smartphones and AirPods cases remain uncharged, leaving users disappointed.

Buy: Scosche PowerVolt USB-C Car Charger (2-pack)

If you're on the road and need a reliable charging solution, the Scosche PowerVolt USB-C Car Charger is a game-changer. This simple adapter transforms your car outlet into two powerful 30W USB-C charging ports. Whether it's your phone, tablet, laptop, or gaming console, you can charge them all simultaneously. And with its Programmable Power Supply, you can trust that your devices will charge efficiently and quickly.

Costco shoppers love this charger, giving it a stellar 4.8 out of 5 rating. One user even compared it to their home wall charger, achieving an impressive charge from 30% to 85% in just 30 minutes.

Skip: Scosche MagicMount Magnetic Phone Mount (2-pack)

Car mounts are a convenient way to keep your phone within reach, but the Scosche MagicMount Magnetic Phone Mount has left some users disappointed. Designed to attach to your car's dashboard or windshield and hold your phone with magnets, it promises a stable display. However, several users have reported issues with the magnetic holder falling out, rendering it useless.

Buy: Aluratek Combo Wireless Car Adapter

For a seamless connection between your phone and your car's infotainment system, the Aluratek Combo Wireless Car Adapter is a must-have. It eliminates the need for a USB cable, allowing you to keep your phone in your pocket or a convenient spot while driving. With a simple toggle switch, you can switch between Apple CarPlay and Android Auto, and it pairs effortlessly with up to two phones simultaneously.

Costco shoppers have given this adapter a solid 4.3 out of 5 rating. Users praise its stability and ease of use, with one even calling it a "very stable adapter" that connects perfectly with both their and their spouse's phones.

The Bottom Line: Quality Over Bargains

While Costco's membership discounts are appealing, it's important to prioritize quality. We've selected our "Buy" products based on their high ratings (at least 4 out of 5 stars), ensuring you get the best value for your money. Conversely, the "Skip" products have ratings below 3 out of 5 stars, indicating potential issues.

So, the next time you're browsing Costco's aisles or online store, remember these recommendations. With a little research and an eye for quality, you can make the most of your Costco membership and find the perfect cell phone accessories.
