While most chargers meet or exceed the power rating, there are some exceptions.The counterfeit chargers perform extremely poorly, putting out a fraction of the expected power. Charging your device with one of these chargers will be a slow, frustrating experience. In particular, the counterfeit UK charger only produces a third of the expected power. Although the label claims the charger works on volts, it’s clearly not designed to work on US power. The plug can be removed and replaced for use in different countries, similar to the iPad and HP TouchPad chargers. I couldn’t find any UL safety approval on this charger, but I did find a report of one catching fire. People often wonder how much power their charger is wasting while it’s idle, and if they should unplug their charger when not in use. I measured this “vampire” power usage and found the chargers varied by more than a factor of 20 in their idle power usage.
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.
Chargers that are rated up to two amperes may be used to maintain charge on parked vehicle batteries or for small batteries on garden tractors or similar equipment. A motorist may keep a charger rated a few amperes to ten or fifteen amperes for maintenance of automobile batteries or to recharge a vehicle battery that has accidentally discharged. Since a battery charger is intended to be connected to a battery, it may not have voltage regulation or filtering of the DC voltage output; it is cheaper to make them that way. Battery chargers equipped with both voltage regulation and filtering are sometimes termed battery eliminators. The problem is, the magnitude of “delta-V” can become very small or even non-existent if high capacity rechargeable batteries are recharged. This can cause even an intelligent battery charger to not sense that the batteries are actually already fully charged, and to continue charging. However, many so called intelligent chargers employ a combination of cut off systems, which are intended to prevent overcharging in the vast majority of cases.
As of April 2016, there are silicon controllers available from several sources such as Texas Instruments and Cypress Semiconductor. Power supplies bundled with USB-C based laptops support USB PD. In addition accessories are available that support USB PD Rev. 2.0 at multiple voltages. Non-standardThe USB standards do not exhaustively list all combinations with one A-type and one B-type connector, however, most such cables have good chances of working. USB plugs fit one receptacle with notable exceptions for USB On-The-Go “AB” support and the general backward compatibility of USB 3.0 as shown. USB 3.x and USB 1.x Type-A plugs and receptacles are designed to interoperate. USB 3.0 introduced Type-A SuperSpeed plugs and receptacles as well as micro-sized Type-B SuperSpeed plugs and receptacles. The 3.0 receptacles are backward-compatible with the corresponding pre-3.0 plugs.
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.
There are all sorts of USB mains chargers out there and whatever youll be charging, eBay has what you need to keep your devices topped up and ready to go. In today’s world of smartphones, there are only a few joys compared to a fully charged battery. But sometimes they might peter out on you at inconvenient times.

Ideally, you want to match your charger, battery, and even the charging cable to the optimal charging speeds that your device supports. You may have noticed that, while you are on the road, you’re quickly running out of juice.
Odds are, you probably have multiple gadgets that need recharging. Why not charge them all simultaneously with this nifty adapter from Anker? It pushes out 43.5 watts of power — that’s three times more than the brick that was likely included with your iPhone. We compared 40 different USB wall chargers to compile this list of the best third-party and multi-port offerings available right now. The very small USB port found on many non-Apple cellphones, tablets and other portable devices is a Micro USB socket. Considerably smaller than USB Type A and B, Micro USB is also half the thickness of Mini USB . Micro USB has been superseded by USB Type C on many new products.
There are cables with A plugs on both ends, which may be valid if the cable includes, for example, a USB host-to-host transfer device with 2 ports.

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.

Its four ports each charge up to 2.4 amps, so you can recharge your smartphone, tablet, wireless earbuds, and smartwatch simultaneously at full speed in less time than you could with their included chargers.
USB-C 1.0 brings in the new power standards and speed advantages similar to that of USB 3.1. Usually the other end of a USB cable uses a Type-B connector. The Type-B plug is the tall plug with the slanted top corners. Variations on Type-B have been widely adopted due to the sheer necessity of having smaller plugs at the client device end.
