The system detects the port type, enumerates, and sends appropriate commands to a charger. The charger handles the hardware and safety aspects of charging, and has built-in limits that will not allow the system to harm the battery . USB has become as much a standard for connecting power to portable devices as it has for serial communication. Recently the power aspects of USB have been extended to cover battery charging as well as AC adapters and other power sources. A tangible benefit of this wide-spread use is the emergence of interchangeable plugs and adapters for charging and powering portable devices. This, in turn, allows charging from a far wider variety of sources than in the past when each device required a unique adapter.

You might find micro-USB ports on certain accessories like Bluetooth speakers, wireless earphones, smartwatch charging stands, and more as well. While PCs can have two kinds of USB port — standard downstream or charging downstream — OEMs haven’t always labeled them as such. As a result, you might have a device that charges from one port on your laptop, but not from the other. This is a trait of older computers, as there doesn’t seem to be a reason why standard downstream ports would be used when high-amperage charging ports are available. Most vendors now put a small lightning icon above the proper charging port on laptops, and in some cases, those ports can even stay on when the lid is closed. You may have to check your motherboard or system documentation to determine which USB ports provide the full capabilities you want. A system might only support charging, video playback, or ethernet over a single USB-C port, even if it has 2-3 USB-C ports in total. Many new phones offer some kind of quick-charge capability — often with variable names, the most common being Qualcomm’s Quick Charge that works with Snapdragon-powered phones.

The super svelte and lightweight Aukey Omnia PA-B4 tops our list. If you own a lightweight laptop, you’ve probably noticed that the charger it comes with isn’t quite as svelte as the device itself. This 18W Quick Charge adaptor hails from one of the best known names in charging tech, and offers very good value. The Quick Charge 3.0 outputs are also backwards-compatible and can deliver a 12W charge to non-Quick Charge devices. There’s an 18W USB-C PD port and a 12W USB-A, making it easy to charge two devices at once. The first of its type that we have encountered, the additional power bank functionality makes the Anker rather large for a phone charger , but significantly more useful if you are frequently on the road. Capable of delivering up to 20W over its single USB-C Power Delivery output, it’s the perfect companion for your smartphone or powering a wireless charger. Aukey’s CC-Y10 performed well in our charging tests and is usually more affordable than the PowerVolt PD40, but it doesn’t fit as snugly in a car’s power adapter. This means it has the potential to slip out of place and stop charging, a common complaint among Amazon reviewers and something we confirmed in our own testing. The Scosche PowerVolt PD40 is our new upgrade pick for people who want two USB-C ports that can simultaneously charge modern phones at full speed.

But the LA DA’s warning also applies to USB cables that have been left behind in public places. Microcontrollers and electronic parts have become so small these days that criminals can hide mini-computers and malware inside a USB cable itself. Something as benign as a USB cable can hide malware nowadays. USB connections were designed to work as both data and power transfer mediums, with no strict barrier between the two. Not only is it packing incredible power, it’s also extremely well designed, it looks great and it is surprisingly small. This is our second entry from Ainope, which has already impressed us with that very attractive model above. This product is also good looking, with a zinc alloy finish that is scratch resistant. This model doesn’t sit quite as flush in the accessory port as the previous one however, and the reason for that is the built in LED screen that is mounted in the faceplate.

The hub may also have some non-removable functions in place of ports. A self-powered hub is a device that provides high-power ports. Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports draw from the hub’s self-power. Proprietary, hazardousExisting for specific proprietary purposes, not inter-operable with USB-IF compliant equipment and possibly damaging to both devices when plugged in. In addition to the above cable assemblies comprising two plugs, an “adapter” cable with a Micro-A plug and a standard-A receptacle is compliant with USB specifications. On the device side, a modified Micro-B plug (Micro-B SuperSpeed) is used to cater for the five additional pins required to achieve the USB 3.0 features (USB-C plug can also be used).

The other chargers vary in quality with the iPhone charger setting the standard for noise-free power, but surprisingly poor filtering of ripple. The first rating is Voltage Sag, which is the undesired drop in output voltage as the load increases. The second rating is Current Sag, which shows how the current fluctuates as load increases. The voltage/current load curve shows the performance of the charger under different loads. Each point on the curve shows the current and voltage produced by the charger under a particular load condition. Follow the yellow curve clockwise from the upper left to the lower left to see the effect of increasing load. The upper left point of the curve shows the voltage produced by the charger when there is no load on the charger.

The USB 3.0 Micro-B plug effectively consists of a standard USB 2.0 Micro-B cable plug, with an additional 5 pins plug “stacked” to the side of it. In this way, cables with smaller 5 pin USB 2.0 Micro-B plugs can be plugged into devices with 10 contact USB 3.0 Micro-B receptacles and achieve backward compatibility. The Micro plug design is rated for at least 10,000 connect-disconnect cycles, which is more than the Mini plug design. The Micro connector is also designed to reduce the mechanical wear on the device; instead,the easier-to-replace cable is designed to bear the mechanical wear of connection and disconnection. By design, it is difficult to insert a USB plug into its receptacle incorrectly. The USB specification requires that the cable plug and receptacle be marked so the user can recognize the proper orientation. USB cables and small USB devices are held in place by the gripping force from the receptacle, with no screws, clips, or thumb-turns as other connectors use. Charges up to 4 electronic devices at the same time via USB connection.

Power Delivery is a revolutionary charging technology that supplies a higher level of power than standard charging offers. It delivers faster charging to the latest PD-enabled devices and is the ideal solution for tablets, laptops and other devices that require more power for optimal charging. Charging time depends on the electronic device battery, the cord used and the electronic device capability. The micro-USB connector is very small and it let manufacturers produce slimmer devices. Micro-USB was widely adopted but is quickly being left behind. That said, some ultra-affordable smartphones even now come with micro-USB ports.
