The Best USB Car Charger (2024)

Senior staff writer Sarah Witman has been a science journalist for more than a decade, covering a wide variety of topics from particle physics to satellite remote sensing. Since joining Wirecutter in 2017, she has written about how to recycle used batteries and electronics, the best wall outlets with USB ports, the best laptop and tablet chargers, and more.

Nick Guy, who contributed to past versions of this guide, has tested thousands of charging accessories for Wirecutter, iLounge, and more.

Even if your car has a USB port designed to sync your smartphone with the car’s entertainment system, and even if that port can charge your phone, spending $20 or so for a dedicated two-port charger can be worth it. The built-in USB ports in most cars put out only 5 W, which isn’t enough to charge a tablet or even newer smartphones at full speed.

If you’re running an app such as Google Maps or Waze, for example, your car’s USB port may not charge your phone faster than your phone uses power, so you can end up at your destination with the same battery level on your phone as when you got into the car. Compared with a car’s port, good USB-A chargers can charge more than twice as fast (12W), and the latest USB-C chargers can charge modern smartphones at 18W to 20W as long as you use a cable that plugs into the smaller port instead of the USB-A cable that probably came with your device. (If you need one, we have a guide to the best cables for iPhones.)

Even if your car’s USB port does offer higher-speed charging, most cars have only one port. All of our picks let you charge two or more devices on a single accessory outlet—something that your family and friends will appreciate.

However, if you recently bought a multiport USB charger that provides at least 2 amps from each of its ports (look for the “output” listing in the small print on the body of the charger), you have less reason to upgrade. Although you’d be able to charge some devices slightly faster with our top picks, the difference wouldn’t be big enough to be worth spending more money on a new model right now.

You can find hundreds of USB car chargers that plug into your car’s accessory-power jack. Over the past few years, these chargers have become significantly smaller, more powerful, and less expensive—just like USB wall chargers.

But most of the car chargers available aren’t even worth considering because they don’t have enough power to simultaneously charge two devices at faster speeds, something that even very inexpensive models can now do. A good USB charger for the car should offer the following:

To find the top options in each category, we then put the finalists through the following tests:

The Nekteck PD 45W Type-C Car Charger is the right charger for any vehicle, any phone, and almost any device you might want to charge while driving. It’s a tiny but powerful charger that has both USB-C and USB-A ports, ensuring near-universal charging compatibility.

Thanks to the USB-C port’s 45 W output, it can charge almost anything at top speed, so you’ll never have to worry about your phone running out of power while you’re using it to navigate, and you can even juice up your laptop on the go. This Nekteck charger also comes with a USB-C–to–USB-C cable, which makes this low-priced model an even better value.

It charges most phones as fast as possible. Most smartphones charge at 15 W to 18 W, so this charger’s 45 W USB-C port is more than powerful enough to charge any smartphone at its fastest rate.

Battery percentage in charging an iPhone 13

In our testing, the Nekteck charger’s USB-C port charged our iPhone 13 from completely drained to about 56% in 30 minutes, and to 85% after an hour (such figures may be slightly lower if you’re using navigation apps). Its 12 W USB-A port, on the other hand, brought the iPhone to about 42% and 75% in the same time periods.

It’s even powerful enough to charge some larger devices. Since many compact laptops charge at 30 W or 45 W, you can even use this Nekteck charger to quickly fill them up on the go. However, a larger laptop, such as a MacBook Pro, will struggle to charge with less than 60 W, especially if it’s in use.

In our tests, the Nekteck charger’s USB-C port charged our iPads at their fastest rates, something that no other model we tested could do. Our 12.9-inch iPad reached 33% charge in half an hour and 65% in one hour.

It has a slick look and feel. The body of the Nekteck charger combines glossy black plastic and matte metal elements, making it look pretty good next to the cheaper designs of some competitors. Also, it has a blue LED to indicate when it’s plugged in.

It sticks out 1.4 inches from the outlet, and its face is an oval 1.6 inches tall and 1.1 inches wide. Although it’s compact and unobtrusive, it isn’t so short that it’s difficult to remove, as some other car chargers are.

It comes with a high-quality cable. This Nekteck charger is the only model we tested that includes a USB-C charging cable. We’ve verified that the cable adheres to standards, and its build quality is sturdy.

It’s made by a brand we trust. Similar to the coverage from most reputable charger makers, Nekteck’s standard warranty period is 12 months, with a six-month extension if you sign up for the company’s newsletter. We’ve found the customer support to be helpful, both in response speed and in addressing our concerns.

Flaws but not dealbreakers

Unlike some chargers, the Nekteck PD 45W Type-C Car Charger doesn’t have illuminated USB ports, so plugging in your cables in the dark is a bit trickier.

If you want to simultaneously charge two phones at the fastest speeds possible, or to take advantage of Apple’s MagSafe Charger in your car, we recommend the Scosche PowerVolt PD40 (CPDCC40). It’s one of the most affordable dual–USB-C car chargers you can get from an accessory maker we trust, and unlike cheaper options, it stays snugly in place to ensure that your phone continues charging.

Each port supports 20 W charging speeds, even when you use them at the same time, and the device overall is about the same size as our top pick, the tiny Nekteck 45 W charger, but not much more expensive.

It charges phones at top speed. In our testing, the PowerVolt PD40 charged an iPhone 13 plugged in with a USB-C–to–Lightning cable from zero to about 53% in 30 minutes and to 83% in an hour. That’s about the same speed as the Nekteck charger achieved, and it’s roughly 15% more battery life than your phone would get from a standard 12 W USB-A charger.

It even has enough power for wireless charging. When it comes to wired charging, 20 W chargers aren’t any faster than 18 W chargers for iPhones. But if you’re using a MagSafe or Qi2 charger in the car, you need 20 W, as found in the PowerVolt PD40, to take advantage of full-speed wireless charging.

It’s a safe buy. Like our top pick from Nekteck, this Scosche charger has a USB-IF certification. Scosche offers a three-year warranty and makes service replacements easy, and Wirecutter staffers who have taken advantage of the company’s warranty have reported a fast and pleasant experience.

If you need only slow-charging USB-A ports, and you want a cheap yet reliable car charger: Get Amazon Basics’s Two-Port USB-A Car Charger, Anker’s PowerDrive 2, or Scosche’s ReVolt (USBC242M). All three models performed basically the same in our testing, have two USB-A ports, and are made by brands we trust. Scosche’s version is a bit shorter than the others, allowing it to blend in seamlessly with most car interiors, and the models from Amazon Basics and Anker have tiny LED lights to let you know at a glance that your devices are charging. If you see any of these three models for $10 or less, buy it without hesitation.

This is not a comprehensive list of all USB car chargers we’ve tested. We have removed any models that are discontinued or no longer meet our specifications.

Anker’s PowerDrive III Duo is a previous upgrade pick. With two 18 W USB-C ports, it’s still a good option for fast-charging two phones at once, but it doesn’t support full-speed MagSafe charging, and the price is now much higher than it was when we first recommended this model.

Baseus’s Enjoyment Pro 60W Car Charger has one USB-C port as well as a built-in USB-C cable, giving you the ability to charge up to two devices with up to 30 W of total output power. The built-in cable is retractable, which is helpful for keeping your console area tidy. But once the cable is fully extended, getting it back into its holster is a bit fiddly, so we found ourselves leaving it unspooled most of the time. Also, it doesn’t give you the option to swap it for a different charging cable (such as one that’s long enough to reach your car’s back seats, able to charge devices via Micro-USB, or encased in a braided-nylon sheath), making it less versatile than otherwise comparable options.

Satechi’s 40W Dual USB-C PD Car Charger was inconsistent in our tests, frequently resetting its signal and not delivering the 9 volts necessary for its top charging speed.

Scosche’s PowerVolt Power Delivery Dual 18W USB-C Car Charger (CPDC8C8) is a good alternative to the company’s PowerVolt PD40, as it performed equally well in our tests. But it has a larger charging face, usually sells for a few dollars more, and doesn’t support 20 W charging for MagSafe.

Spigen’s SteadiBoost USB-C PD3.0 Car Charger offers less total power than the Nekteck charger we recommend, and it doesn’t come with a cable. It also charged the iPhone 13 a bit slower in our tests—45% in half an hour in comparison with the Nekteck charger’s 56%, and 79% in an hour versus 85%.
