The regulation is good but not perfect, as shown by the width of the yellow line. (The gaps in the vertical line are just measurement artifacts.) Note that the maximum current output of this charger is fairly low . The KMS charger shows a lot of voltage sag as the load increases. In addition, the output is all over the place, showing very poor regulation, more like what I’d expect from a counterfeit charger. The output of this counterfeit charger is so poorly regulated that it’s hard to tell exactly what’s happening with the voltage and current. It looks like the voltage is roughly constant underneath all the noise. The Monoprice charger shows reasonably straight voltage and current lines showing good constant voltage and current outputs. The vertical line shows some width and noise, suggesting the regulation isn’t totally stable.
On top of that, the device is UL certified, which makes this 6 port charging hub a go-to pick if you need a secure way of charging your USB-powered devices. The Anker PowerPort 6 is a truly universal model that can be used anywhere you go. The main reason for that is the ability of the device to operate in the voltage range from 100 V to 240 V without overheating or failing. The device features 6 USB output ports that will definitely come in handy for those who have more than a couple of phones and other mobile devices that can be charged via USB. Another advantage to the multiple port USB chargers is their portability. Most are small and lightweight enough to carry in a briefcase or purse. If you are a large family with numerous electronic devices, a USB charger with multiple ports will make road trips much easier. Wall chargers connect to standard 120V electrical outlets to provide USB ports for charging devices. Some compact devices need high charge currents but cannot tolerate the excess heat that those charge rates would generate in a linear charger. In those situations the MAX8903 operates a 4MHz DC-DC converter that keeps the component footprint small while still delivering up to 2A to the battery from adapter sources.

It might be tiny, but this compact charger from Aukey can charge two devices at once, with both a USB-C PD output and a full-size USB. These USB adaptors are not powerful enough to charge a laptop and some games consoles, however. For that you need a Quick Charge 4/4+ or Power Delivery charger, which can output up to 100W over USB-C. We’ve rounded up the best laptop chargers in a separate article. Phones are capable of increasingly fast charging, but it’s rare that a charger that can support these top speeds is supplied in the box. That’s if a charger is supplied at all, and many of us are still using old 5W chargers that are painfully slow. Passengers can charge their devices by plugging them into this USB port on the back of the seat in front of them. Aukey’s Expedition Flush-Fit 18W is a tiny metal charger offering a single 18-watt USB-C port. We generally recommend chargers that don’t sit flush because they are harder to remove, and overall you can get a better deal on a multiport charger.

The most notorious is Mactans, presented at the Black Hat 2013 security conference, which was a malicious USB wall charger that could deploy malware on iOS devices.
Besides the standard type-A and type-B configurations with 4 pins, there are also the USB Mini-A, Mini-B, Micro-A and Micro-B that include an ID pin to permit detection of which cable end is plugged in. USB cables are generally standard type-A on one end and either type-B, Mini-B or Micro-B on the other. The new type-C connector described later features 24 pins and runs on the USB 3.1 standard. A typical USB network consists of a host that is often a PC and peripherals such as a printer, smartphone or camera. Data streams in both directions but the power is unidirectional and always flows from the host to the device. If you need a USB port but only have 3.3V of power, or need to power a downstream uC even when your switch is off, a switch with boost or switch with LDO may be right for you. Prime deals company has released a very attractive charger. Black, white, blue, rose red colors are available to customers.
This model looks great but to a certain extent that doesn’t really matter too much. You see, the body of the charger will be hidden out of sight, with only the top plate visible, completely flush with the accessory port. The part that is visible boasts an all aluminum construction whilst the port glows with a very pretty – and actually very useful – blue light. Of course, if you’re praying about USB chargers, it might be wise to redirect some of that energy.

No matter what device you need to charge, your Feeke power bank can handle it. The Aukey Focus Duo 36W Dual-Port PD Charger (PA-D2) is one of the few power bricks we’ve seen with two USB-C ports, and it’s the most impressive for its size. The PA-D2 delivers the promised 18-watt performance when both ports are in use, so you can charge two phones at full speed at the same time or fast-charge your phone and another USB-C accessory. If you’re using only one of the ports, that speed jumps to 30 watts, enough to power a tablet or some laptops. No other charger of this size is that powerful, and most dual–USB-C chargers cost about the same as this one, so you have no reason not to get the extra power. Although the USB-C port is smaller and faster than USB-A and works with more kinds of devices, the USB-C standard is not yet ubiquitous. A car phone charger must be compatible with a person’s cell phone and vehicle.
Much to my surprise, the HP TouchPad charger (which isn’t sold any more) turned out to have the best overall score. The counterfeit iPhone charger set a new low for bad quality, strikingly worse than the other two counterfeits. Some USB devices require more power than is permitted by the specifications for a single port. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this. Devices can request higher currents and supply voltages from compliant hosts – up to 2 A at 5 V , and optionally up to 3 A or 5 A at either 12 V or 20 V . In all cases, both host-to-device and device-to-host configurations are supported.
A charging downstream port can be found on a computer or laptop and can supply up to 1.5A, whilst allowing a USB to be detected and begin charging before enumeration . There are three types of USB port dictated by the actual current specs . Certified USB devices are in general very safe to use, as long as they are used correctly in accordance with the manufacturer’s instructions. The headline feature of the USB-C is that it’s reversible. It’s designed to be small enough to not need any mini or micro variants. The intention is that it will completely replace all types of USB on both host and client devices.
