The 12-volt power outlet in cars isn’t just for cigarette lighters anymore. While modern vehicles often include USB ports for charging, older cars still rely on that trusty 12V outlet. You can power various gadgets with it, including phone chargers, tire inflators, and small vacuums. However, it’s important to choose products from reputable brands. Using the wrong device could drain your car battery or even damage the gadget.
If you’re driving an older car and want to maximize your 12V outlet, check out these four highly-rated gadgets that could enhance your driving experience.
Anker 535 Car Charger
The Anker 535 Car Charger is a solid choice for charging multiple devices. It has two USB-C ports and one USB-A port, allowing you to charge up to three devices at once. The USB-C ports can deliver up to 67 watts of power, making them suitable for laptops and quick phone charges.
One caveat to consider: when using all three ports together, one USB-C port delivers 45W while the other two provide only 9W. This limitation has been noted by some users, especially those who frequently charge multiple devices. Still, it boasts an impressive average rating of 4.8 stars on Amazon from over 3,500 reviews. Priced around $44, it often goes on sale, making it a great deal.
AstroAI Tire Inflator
Every car owner has faced a tire pressure issue. The AstroAI Tire Inflator makes handling that problem easier. Weighing only 2.2 pounds, it features a backlit display, a nearly 10-foot long power cord, and operates up to 100 psi. Just set your desired pressure, connect the nozzle, and let the inflator do the work.
It’s reported to add about six psi in a minute, making it an essential gadget for road trips. It also comes with multiple nozzle adapters and an integrated LED flashlight for nighttime use. Priced at around $40, it enjoys an average rating of 4.5 stars on Amazon. However, some users have reported receiving defective units, so buyer beware.
Syncwire Bluetooth FM Transmitter Adapter
If your car lacks Bluetooth, the Syncwire Bluetooth FM Transmitter is a perfect solution. This device plugs into your 12V outlet, allowing you to stream music from your phone to your car’s radio. You can also use it for hands-free calling through your car speakers.
The adapter has a USB Type-A port that delivers 18 watts of power and a USB-C port with 36 watts and USB Power Delivery support. It’s well-reviewed with an average rating of 4.4 stars and retails for about $30. However, some users have noted issues with sound quality and low volume, so keep that in mind when considering this option.
Amazon Echo Auto
In the world of smart technology, older vehicles can benefit from the Amazon Echo Auto. This compact device brings Alexa’s voice features to your car. It connects to your car speakers and harnesses your smartphone for connectivity.
It comes with an auxiliary cable and a 12V plug with a USB charging port. Though it has a built-in speaker, it mainly uses the car’s sound system for playback. Echo Auto is priced at around $55 and has an average rating of 4.2 stars. Some users report disconnection issues with the Alexa app, but you can usually return it if it doesn’t meet your needs.
When selecting these gadgets, we focused on products that genuinely enhance your driving experience while ensuring they come from reliable brands. Each gadget has at least a 4.2-star rating, based on user reviews, confirming their effectiveness and quality.
