This USB car charger by Anker delivers 24 W of fast-charging speeds while on the move. Its premium exterior shell is crafted from aluminum alloy and features a scratch-resistant design. Inside this robust shell is the incorporation of gold-plated circuitry to reduce heat and maintain optimal charge speeds for prolonged periods. This fast-charging car charger boasts a multi-protect safety feature to keep you and your device safe. The charger is suitable for both Apple and Android devices and is available in supported phones and is available black, red, and silver. A dedicated charging port applies to power sources like wall chargers that do not enumerate, so charging occurs with no digital communication at all.

A second problem is the output voltage can be affected by the AC input, causing 120 Hz “ripple”. Third, the charger is supposed to provide a constant voltage. A poor design can cause the voltage to sag as the load increases. Your phone will take longer to charge if the charger doesn’t provide enough power. Finally, USB chargers are not all interchangeable; the wrong type of charger may not work with your device. Since these currents are larger than in the original standard, the extra voltage drop in the cable reduces noise margins, causing problems with High Speed signaling. To charge your USB devices, simply connect the four-foot power cord’s NEMA 1-15P plug to an AC power outlet, and connect your devices to the available USB ports. The unit protects against overheating, overcurrent and overcharging—in fact, it stops charging as soon as your devices’ batteries are at full capacity.

In our tests , the RAVPower Pioneer RP-PC133, delivered a full 15 watts (3.27V, 4.72A) from its Type-A port while also providing up to 54.9 watts (19.6V, 2.8A) from its USB-C port at the same time. As of this writing, Aukey’s Omnia PA-B2 is the smallest USB-C laptop charger on the market. This diminutive wall wart measures just 1.77 x 1.77 x 1.18 inches, which makes it even smaller than RAVPower’s tiny Pioneer RP-PC112, which is just 1.9 x 1.9 x 1.2 inches itself. The Omnia PA-B2 is also a full 0.45oz lighter than its competitor. If you’re using a 16-inch MacBook Pro or another USB-C laptop that requires more than 65 watts of juice, the Aukey Omnia PA-B5 is your best bet. Though it is conservatively rated for 65 watts, in our tests, the 3.65oz Aukey Omnia PA-B4 managed a maximum sustained rate of 72.6 watts (19.2V / 3.78A). After 20 minutes of that maximum the temperature hit a steamy 139 degrees Fahrenheit, but the charger was a much cooler 120 degrees, the second coolest of all chargers we tested, when run at 64 degrees. We benchmarked several USB-C laptop chargers with Gallium Nitride to help you find the right one for you. This Aukey phone charger is about as dinky as they come, just a couple of inches wide and an inch thick.

Most car chargers, if treated well, can last for a few years. However, like most electronic components, car chargers too can suffer sudden failure. Thankfully, since most have inbuilt-safety features, your devices and you are kept safe. Before you make that all-important purchase, revisit our list of the 11 best USB car chargers and choose the one you like the most. Much of its popularity arises from its super-quick charging speeds coupled with dual smart charging technologies. Built into this compact car charger is a PD 3.0 PPS fast-charging chip and a QC 3.0 fast charging chip. The 2 Type-C USB ports have a 65 W and 30 W rating, while the QC port has a rating of 18 W. The sheer brilliance of this charger is its ability to fast charge iPhones and Android smartphones and tablets.

But they all work fine, and any of them is a decent buy if you find a great sale or it’s easier to pick up one of these over the ZMI PowerCruise C2. Like every dual-port charger we tested, the PowerCruise C2 properly allowed 12-watt power draw from both ports. An iPhone 12 should reach 44% from empty in half an hour and about 77% in an hour. Unlike some chargers, the Nekteck PD 45W Type-C Car Charger doesn’t have illuminated USB ports, which would make plugging in cables in a dark car a little easier. 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. In our tests, its USB-C port charged the 11- and 12.9-inch iPad Pro tablets—both of which are capable of laptop-like 45 W charging—at their fastest rates, something no other car charger we tested could do.

Both models are nearly identical in size and shape, and supply up to 20 watts over USB-C. Whether you have an iPhone, a Samsung Galaxy model, a Google Pixel handset, or some other Android phone with fast charging, that’s enough power to charge most phones about halfway in just 30 minutes. They will also power Apple’s MagSafe wireless charging system at its maximum 15 watts. These chargers are exactly the same size and performed identically in our tests, so you should get whichever is cheaper when you’re ready to buy. Some MP3 players use USB chargers to recharge their batteries. Many personal electronics come with an AC charger only; a cable with a USB connector on one end and a standard AC plug on the other.

This ensures each device gets the power level it needs to charge fast and efficiently. What if you already have a third-party cable or don’t have any option but to use one? This is preferable, in the sense that it won’t actually damage any of your hardware. In many cases, your device will only charge at minimum or near-minimum speed as opposed to the fast charging options now supported by many devices. This chart from Android Authority shows how charge speed varies depending on which device you use. While you won’t blow up your device from plugging in the wrong charger, you can blow up your phone, Nintendo Switch, or other device by using the wrong USB-C cable. In the past, there’ve been spreadsheets dedicated to recording good versus bad cables, but the projects seem to have fallen by the wayside and are now outdated. If you are buying a replacement USB-C cable for your manufacturer-provided cable, we recommend buying from the OEM or an authorized, third-party manufacturer. We covered the initial issues with USB-C in more detail in this article.

Finally, the above pictures show the internals of the Samsung cube charger, which has circuit boards packed with tiny components and is much more advanced than the counterfeits . Despite being very similar to the Apple charger on the outside, the Samsung charger uses an entirely different design and circuitry internally. One interesting design feature is the filter capacitors fit through the cut-out holes in the secondary circuit board, allowing the large filter capacitors to fit in the charger. The above picture shows the internals of a counterfeit Apple iPhone cube charger. This charger blatantly tries to pass as a genuine Apple charger; unlike the “Designed by California” charger, this one exactly copies the “Designed by Apple in California” text from the real charger. Note the very simple circuitry – there are no components on the other side of the board, no controller IC, and very little filtering. Also look at the terrible mounting of the transistor on the front right; clearly the build quality of this charger is poor. Finally, note the overall lack of insulation; this charger wouldn’t meet UL safety standards and could easily short out.

It’s black, slightly textured, and has the AmazonBasics logo on top. There’s a long power cord supplied and a power switch on the side. Small yet mighty, it keeps your devices charged on the go or at home and comes with a long charging cord. If you don’t fancy the black option, it’s available in navy blue or white, too — and its solidly-positive reviews make this well worth the money. For example, I almost always charge my ASUS Chromebook C302 with my Pixel 2 XL’s charger when I’m at home, and I’ve used my C302’s charger on my Pixel multiple times when I’m out. I leave the C302 charger in my bag all the time and the stock Pixel charger plugged up, so it works out well. This is why you can use a Quick Charger on older smartphones that don’t support Quick Charging technology—both the charger and the battery have the necessary safeguards in place to keep anything bad from happening. The phone will just charge at the normal speed its designed for. With its smaller connector head and symmetrical, reversible orientation, it fits easily into phones, tablets, laptops and more.
