However, prior versions of USB could handle a limited amount of power, which is why laptop chargers have typically retained their larger, bulkier cables. The fact of the matter is that if you're packing the right kind of charging cable , and your laptop or device was released in the past couple of years, you'll be in very good shape. The key, of course, is getting one of the latest and greatest USB-C power delivery chargers. Thankfully, I've spent the past few weeks testing some of them, and I've found some go-to choices for fast charging on the go. You can find no shortage of small, $10-ish, dual-port USB-A chargers from reputable brands. AmazonBasics’s Dual-Port USB Car Charger, Anker’s PowerDrive 2, Aukey’s CC-S7, and Scosche’s ReVolt all perform identically to one another. Some models are shorter than others and end up looking like they’re part of your car when installed, and some have glowing ports that make it easier for you to plug in a cable when it’s dark.
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.
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.
This decreases the efficiency of the battery, resulting in less net current available to be drawn from the battery. Since the Universal Serial Bus specification provides for a five-volt power supply , it is possible to use a USB cable to connect a device to a power supply. Products based on this approach include chargers for cellular phones, portable digital audio players, and tablet computers. They may be fully compliant USB peripheral devices adhering to USB power discipline, or uncontrolled in the manner of USB decorations. Inductive battery chargers use electromagnetic induction to charge batteries. A charging station sends electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metal contacts between the charger and the battery.
USB 1.0 is old enough that you’ll virtually never see it, so USB2 – USB 3.2 covers the spectrum for most people. Separately from that, there’s USB-C, which is a physical connection standard that devices can use. In almost every case, your PC is the host, and your smartphone, tablet, or camera is the device. Power always flows from the host to the device, although data can flow in both directions, such as when you copy files back and forth between your computer and your phone. The descriptions below apply to all versions of USB currently in-use, including USB 3.0, 3.1, 3.2, and their various substandards (1×2, 2×2, etc). Wattage Find out the wattage needed for the device you own before purchasing a charger. While most USB-C chargers will be able to accommodate smartphones and tablets, those looking to charge compatible USB-C laptops will need to ensure that their charger has enough juice for the job.
Charging power is quite strong with this port, offering 2.4A at every plug-in. On the other hand, you can definitely use your USB-C laptop charger to juice up your smartphone. Again, those safeguards we talked about earlier will allow the charger and battery to talk with each other and automatically default to the fastest allowed charging speed. This is what we’d generally think of as a “slow” charger, since the majority of modern chargers are much faster now. Having some knowledge regarding USB chargers and cables, you should be able to find the perfect charger to fit your needs. You can also eliminate that power-strip containing numerous individual chargers cluttering up your kitchen counter or another area of your home by consolidating chargers.
Additionally, USB power delivery augments the basic USB charging speeds for up to 100W of output power. The amount of available power is split into different power ratings, which operates at different voltages. I’ve been researching Type-C power banks and chargers, and like you would have noted, it’s hard to find quality stuff that is rated for 60W plus. There is a full featured Microsoft certified data+power adapter as well as 3rd-party power-only USB-C charging cables from several brands.

The spectrum shows high frequency noise at the switching frequencies. This counterfeit charger has so much noise in the output that I had to double the scale on the left to get it to fit. The spectrum is much higher everywhere, indicating noise at all frequencies. Surprisingly, it has only a moderate amount of ripple; the manufacturer seems to have done at least one thing right. The large degree of ripple is visible in the waveform and the very large spikes in the spectrum . The thickness of the yellow waveform shows the large amount of high-frequency noise, which is also visible in the very high peaks in the spectrum .
