If it exists, Amazon probably sells it. The breadth of its inventory is unmatched, and buyers can find virtually any tech product, from robot vacuums and smart rings to security devices and home theater equipment. Some gadgets feel like simple gimmicks, adding little value to your everyday life, while others are fun or genuinely useful.

With Amazon constantly adding new products, it's easy to get lost in the noise. Most of us are familiar with smart TVs, AirPods, and the Amazon Kindle, but the online retail giant offers alternatives to popular products and items you may not even know exist. Whether you're a tech enthusiast or gearing up to start your holiday shopping, Amazon offers something for everyone. We've gathered four products that are engaging, can solve an everyday problem, or may make a great gift. All prices are current as of publication, and we only included products with mostly positive customer reviews.

The Kindle is not the only e-reader sold on Amazon. This ultra-compact reader is a budget-friendly, portable alternative. Instead of spending $150 on the newest Kindle, the XTEINK X4 Pro is only $99 and is small enough to slip into your pocket. Sure, you can download the Kindle app on your phone, but it's easy to get distracted from your latest novel by notifications and social media. This little reader has an e-ink screen with a dual-tone front light, so it's easier on your eyes than the blue light emitted by your phone.

One of the coolest features is this reader's magnetic back, which allows you to safely attach the reader to the back of your phone. According to XTEINK, the reader fits more than 98% of smartphones. It has a 5.95-millimeter profile and weighs only 2.5 ounces. Users can touch the screen to adjust brightness and color temperature and turn pages, or use the side page-turn buttons. To import books, use a USB cable to drag-and-drop files directly, or use the XTEINK app. One charge via the magnetic pogo pins typically lasts one to two weeks. If you're a voracious reader, you can expand the device's memory with a microSD card supporting up to 256GB.

There's no denying the usefulness of Apple's AirTags. They can help you track down lost luggage or find your car keys when you forgot where you've put them. When it comes to tracking your wallet, however, AirTags aren't always the best solution. Their size and shape mean they can't fit into thinner places. If you want to add a tracker to your wallet, you should consider something like the Ridge Tracker Card instead.

Tracker cards are designed specifically for those credit card slots in your wallet. There are several options available, but the Ridge card is compatible with both Apple and Android technology. Users can receive real-time, trigger alerts and enable Lost Mode in Apple Find My and the Google Find Hub. Currently priced at $29 for the black card, it's the same price as the Apple AirTag.

Unlike the AirTag, the Ridge Tracker Card is rechargeable, with a 155mAh battery that wirelessly recharges on any Qi or MagSafe charger. A single charge lasts up to five months. The card is also water-resistant, and you can securely share tracking data with up to five contacts. If you misplace your wallet at home, the card has a speaker that will emit a loud ringer to help you find it.

Apple introduced CarPlay in 2014, but it didn't become a standard feature until around 2020. If you own an older vehicle or a new one from a manufacturer that doesn't support CarPlay, like Tesla, Rivian, and, at times, GM, you may be stuck without a way to safely, effectively, and wirelessly connect your smartphone.

This 7-inch wireless CarPlay screen from 25HOURS could be the solution you're looking for. It offers high-definition 1024x600 resolution and will work in temperatures from -4 degrees Fahrenheit to 167 degrees Fahrenheit. Users can either secure it to the dashboard with the adhesive mount or suction cup mount. The screen comes with an 11.5-foot power cord that works with 12V-24V plugs (often called cigarette lighters in cars) and an auxiliary cable. Drivers can play music, take phone calls, and get navigational prompts via Bluetooth. The screen, which rotates for portrait or landscape mode, can also mirror your phone.

This product may be dubbed a CarPlay screen, but it does more. It also pairs with the included 1080p backup camera, which has a 19.7-foot cable and is designed to fit sedans, SUVs, and pickup trucks. It has a wide-angle lens, night vision, and parking guidelines. This CarPlay screen package is currently priced at $49.99 and comes with a 12-month warranty.

Whether you frequently travel solo or you just love a good James Bond movie, this little gadget is a seriously cool piece of tech that may help you sleep better when you're away from home. Made by a company called Nilcozy, this device acts as an RF detector to pick up wireless signals. It will find hidden cameras, listening devices, and other surveillance equipment. It scans in all directions and has a built-in rechargeable battery. 

The detector has five adjustable sensitivity levels and will also act as a flashlight, with an LED light mode that activates with a short press. You can easily slip the detector into your purse, luggage, or pocket. It's less than four inches long and is intended to help ensure personal safety in hotels, rental homes, offices, and other public areas. At time of writing, this device is on sale for $35.99, but its typical price on Amazon is $59.99.
