We also love this charger because it’s smaller and lighter than many of the others on this list. If you really only have a few different devices you regularly need to charge, then the USB-C and standard USB port should do the trick while cutting down on the amount of weight you have to carry around. We all know how heavy some laptop chargers can be, and the Aukey PA-B3 is compact and light enough to make a difference if it’s in your work or school bag every day. The best USB-C chargers restore your device’s battery quickly and efficiently. When searching for your next charger, make sure to take into account reliability, watts, and ports. It’s one of the few chargers on the market that’s equipped with dual 45-watt USB-C ports. This means you can fast-charge two iPhones up to 50% in just 30 minutes. If you were using the charger that came with your iPhone, you’d only be at about 20% in the same amount of time.

But, if you see an Anker PowerPort model on sale, it’s certainly worth scooping up. (If you really can’t tell, this last part is ironic)I am also have an EE degree, and yes the terms you listed are a bit nebulous. However, your little rant about PC culture and how you are not female, gay or black is why you don’t get taken seriously – I am not sure what any of that has to do with anything. Go back to the right wing white male grievance sites, and stay off of tech sites – there are ALOT of non-white people involved here, some of them might be women, and some of them might be gay. @TJ HookerGood one, I never thought about voltage though I wouldn’t know another English term, maybe potential or something like that. In my native language we do have a proper word for that, and in Dutch people also use the voltage, amperage and wattage and those are all wrong. About the take issue this is somewhat ironic, I don’t really care that much, though it does stand out in an article in negative way, so therefore I wanted to mention it. Perhaps just as important as the Aukey PA-B5’s output is its size and weight. This wall wart is just 2.24 x 2.24 x 1.26 inches and 5.3 ounces, which compares very favorably to the RAVPower Pioneer 90W (RP-PC128) that tips the scales at 6.7 ounces with dimensions of 2.5 x 2.5 x 1.2 inches. Our resident Xiaomi expert and a follower of all upcoming phones, she is also the go-to for charging tech.

The point is that USB chargers are not interchangeable, and devices may not work if the charger type doesn’t match what the device expects. The table below shows the type of charger, the current that the label claims the charger provides, the current it actually provides, and the charger type it indicates to the device. A device being charged can detect what type of charger is being used through specific voltages on the USB data pins.Because of this, some devices only work with their own special chargers. A USB charger that follows the standard is known as a “dedicated USB charger”. However, some manufacturers don’t follow the USB standard but implement their own proprietary charger types. Apple has separate charger types for 1 amp and 2 amp chargers. The chargers are rated from 1 to 5 energy bolts, with 5 bolts the best. The overall rating below is the average of the ratings in nine different categories, based on my measurements of efficiency, power stability, power quality, and power output. The quick summary is that phone manufacturers provide pretty good chargers, the aftermarket chargers are worse, and $2 counterfeit chargers are pretty much junk.

It’s sturdy and features a fairly unobtrusive look, apart from the unfortunate Xcentz logo. Wattage is the rate of water output, which is found by multiplying the voltage by the amperage. To understand charger compatibility, you first need to understand how they work—at least on a rudimentary level. Thunderbolt3 and USB Type-C (3.1 Gen2) share the same cable type and port. Type-C is the physical shape of the connector, USB 3.1 and Thunderbolt3 are features embedded in the connector. Leviton USB wall outlets are compatible with most widely used cables on the market today.

Conserve the lifetime of your battery by disconnecting when fully charged. Leviton has been at the forefront of developing electrical products with your safety in mind for over a century and our outlets with USB ports are no exception. Keeping your smartphones, tablets and other electronic devices up and running is essential to staying connected to family, friends and business. Whether you have one device or many, we have a Leviton USB outlet that is right for you. This was the standard for various devices a while back but was quickly replaced by the micro-USB connector mentioned below. You’ll find it on older models of various gadgets especially cameras, MP3 players, and game controllers, among others. As its name suggests, it’s smaller than a regular USB, but larger when compared to its successor. If you’ve ever needed to charge anything, from smartphones to tablets, to cameras and even new laptops, you’ve likely needed to use one. However, USB cables come in different shapes and sizes despite the fact a lot of them do the same things. In this short and handy guide, we’ll take a look at all the different types of USB cables available on the market and give you some examples where you might find them in use.

You will need to solder one 150k ohm resistor to the data- pin/wire of port 1, as well as to the data+ pin/wire and also to both data pins/wires of port 2. Then you need to solder a 560k ohm resistor to both ground pins/wires and both 5V pins/wires. Then solder the other sides of all resistors connected to port one together, and do the same with port 2. If you’ve purchased a new, current phone over the past couple of years, chances are you were notified of quick charging when you first plugged it in with your unique charger. Your best bet, at least as far as Qualcomm’s Quick Charge goes, is to find Qualcomm-certified chargers. Chargers straight from your phone’s manufacturer should work, too. They’re often found at the bottom of our smartphones and tablets for charging up the battery. They’re also found on a myriad of other devices and hardware in the market.

The two additional USB-A ports take advantage of Anker’s PowerIQ technology to ensure the best charging speeds for other devices. Yes, USB-C power is pretty great — except that nearly every airline seat, coffee shop, airport lounge and hotel room now seems to be equipped with those old-fashioned USB-A charging ports. That’s why it never hurts to keep some adapters on hand for your device. The Elebase dongle shown above includes an integrated keychain that keeps it attached to the main cable. Not exactly elegant, but it gets the job done — at $9 per pair. While I, too, lack an EE degree – is it just me, or is the methodology employed for this articles’ tests a flawed one? If a charger had dual ports, we plugged one port into a USB-C phone while we used the other with the load tester.

The answer to this question is not as simple as it sounds. This is because it entirely depends on the make of the car. Some cars are programmed to shut off the cigarette lighter ports as soon as the engine is switched off, while others may have a timer that leaves it on for a short period. Cheap devices often fail to meet the requirements of the Electrical Equipment Regulations Act 1994. The money that you save comes with extremely high risks and therefore buying a branded/certified charger is essential to avoid often fatal repercussions. Plugging USB devices into “smart” products such as laptops and tablets which monitor and control the output should, in theory, be safer than the use of wall sockets. However, as always, check the manufacturer’s instructions.

This ensures that any device plugged into the port will receive power before data transfer is attempted, cutting down on data errors. This design has another advantage when it comes to digital music players. With larger device batteries, new charging technology like Qualcomm’s Quick Charge, and formats like USB-C that allow for better charging throughput, chargers are more complex than ever. If interested, you can find any charger’s output information written intiny text somewhere on the charger itself. You certainly need to make sure you have an adequate number of ports to charge all your electronic devices. If you currently have two devices, for example, then do not limit yourself to a charging station with only two ports.

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 .
