How Do AC to DC Power Adapters Work?

Most electronics run on direct current (DC) power. This is the type of power that batteries put out, and it is straightforward to deal with when engineering electronics. However, the power Adapters that runs through power lines and homes is alternating current (AC) power. Alternating in this case refers to the fact that AC power switches direction back and forth quickly, flowing in both directions along an electrical line. This bidirectional flow would damage DC equipment, which is only capable of handling power flowing in one direction, thus the need for an AC/DC adapter.

To convert alternating current into direct current, an AC/DC adapter makes use of an electronic component called a rectifier. This component takes an electrical input and only allows power to flow in one direction out of it, effectively creating DC power. Rectifiers are only capable of handling a certain level of electrical current before they are irreparably damaged, so make sure to check your power adapters before bringing them to location with different levels of AC power. For example, do not attempt to use adapters rated only for U.S. (110 volt) electricity in Europe, where electricity is typically 220 volts. Failure to take this into account could result in damage to your power adapter or electronic devices.
Voltage and Amperage

Unlike AC power, which is well standardized for voltage and amperage within a country, DC power required for a piece of electronic equipment can vary wildly. Make sure not to use a AC/DC adapter on your electronics that is not rated for a different voltage, as you run the risk of damaging your equipment. Using a power adapter rated for a higher amperage than your electronic equipment is safe, as the equipment will only draw the necessary current.

Overview of common lead acid battery sulfuration removal methods

Battery charger sulfuration is one of the most common reasons to reduce the battery life and in order to have a long battery life, we must avoid battery sulfuration phenomenon earlier. The electric vehicle battery sulfuration is generally because our vehicles can't get timely charge after use. Some small crystals, will be formed inside the battery when the battery becomes sulfation, and these small crystals will be adsorbed on the electrode plate of the dedicated battery of the electric car, blocking the current channel, leading to the deterioration of the battery performance, shorter life!

To avoid electric vehicle batteries sulfuration, Leoch suggestions: First, we will provide timely charge to the batteries of electric vehicles; Second it's necessary to adopt some of the sulfuration removal devices for removing sulfuration. Sulfuration removal methods are

Desktop sulfur removal equipment works fast high voltage and high current pulse charging, eliminate negative blocking wearing sulfide battery. This method is fast, effective, and can be temporarily eliminate the effect of sulfide, high voltage and high current, however, able to strike desulphurization addition to the active substance in the elimination of sulfide bring severe dehydration and positive plate softening after such equipment in addition to the basic will of sulfur twice battery scrap battery fatal injury. At present, the market appeared a pulse discharge of sulfur removal equipment, in fact, the fundamental principle has not changed, just from the constant high pressure Hengda current becomes instantaneous peak high-pressure, or will damage the electrode active material, this method should be used with caution .

May be in addition to sulfur charger works similar to desktop sulfur removal equipment works fast, high-voltage high-current pulse charging, blocking by negative wear in addition to sulfur, has been described above, this method of battery life would constitute a fatal injury, has been negated. The second is the use of a fast pulse edge of charging and discharging pulses, the use of the instantaneous peak, and to interfere with the vulcanization of the battery during the charging process. Another is periodically using 10% to 20% over the method of charging, the lead sulfate crystals of the reduction cell. Both chargers can charge when sulfur removal, but it will cause less or overcharged, it also ignores the fact that of the battery discharge process is the most important of the vulcanization process, so the effect is not ideal.

Online lead-acid battery Nobu batteries in parallel twenty-four hours of stop and eliminate sulfide. This approach fix a slow, long time to repair, often in more than 120 hours, but both charge-discharge process can prevent and eliminate sulfide, repair works well. Low-voltage, low-current, Nobu does not have a powerful impact on the battery plates and lead to dehydration and soften a user once put into maintenance mode can be sustained, especially for the better quality of the new battery can be extend battery life by 2-5 times, and time invested, along with the electric automobile, the next time to replace the battery, Nobu can also continue to use, can save a lot of economic cost for the user.

In a word, the ultimate solution: Anti greater than governance, usually dedicated lead acid battery charging for electric vehicles in a timely manner, and pay more attention to maintenance, which allows for electric cars to achieve the design life of the battery in the case of normal use, then why should these troubles.

Five Tips on Choosing USB Hubs

We are a professional manufacturer with more than 10years, who specialised in lead acid battery charger,

With USB devices becoming ever more ubiquitous, USB hubs are becoming more and more useful as well. And with more and more USB hubs on the market, it can be hard to decide what to get. Below are 5 tips on choosing the best USB hub for yourself.

USB hubs with anything between 3 and 13 ports can be found easily on the market, but is more really better? There's no point in buying a 13-port hub if you don't plan on using 13 USB devices simultaneously with your computer or OTG smart device; you'll only be getting a heavier, less portable device that you won't even need. Seven tends to be a good middle number, and if you are looking for something more portable, a 4-port hub would be the way to go.

Are you looking for a hub that you can take along with a laptop, or do you just plan to use the hub at home with a desktop? Hubs of all sizes exist to meet your needs, whatever they may be. Miniature 4-port hubs like the one in the picture on the right can be easily taken with you wherever you go, allowing you to use multiple USB devices simultaneously with your computer or OTG device. Vertical desktop hubs like the one in the picture on the left, meanwhile, offer you more ports while saving space. Horizontal hubs likes the ones shown in point 1 can be found in abundance, too, though these tend to take up more space and be harder to rearrange than vertical ones.

With more and more new computers featuring USB 3.0 ports, more and more USB 3.0 hubs have come onto the market as well. USB 3.0 offers transfer speeds of up to 5 Gbps theoretically, which is ten times faster than that of USB 2.0. However, if your computer doesn't have any USB 3.0 ports (and since pretty much all smart devices are still using USB 2.0), then there's no point in getting a USB 3.0 hub, not unless you are planning to upgrade your computer soon.

A good number of hubs these days feature charging ports in addition to standard USB ports. These charging ports are dedicated to charging, and while some ports can only output 1A of power, others can output 2.4A, making them just as fast as some external batteries or AC adapters. Now, instead of having to get up to plug your phone or tablet in, you can just connect it to your hub, letting you continue working on your computer without too much interruption. However, if you what value most is portability and/or you already have multi-port USB chargers, then this sort of hub may not be so necessary.

In addition to the charging capabilities above, many USB hubs often feature other fancy abilities as well. Some hubs come with card readers, while others include OTG cables, allowing them to be used straight out of the box with OTG devices. Still others, such as the one in the picture on the left above, include a stand feature that allows you to use your device handsfree. If you don't have a separate card reader, OTG cable, or stand, you might want to consider a hub with these extra features. On the other hand, if you do, then a simpler hub might suffice.

How Lithium-ion Batteries Work

Lithium-ion batteries are extremely popular these days. You can find them in PDAs, laptops, cell iPods and phones. They are so common because, pound for pound, they are some of the most energetic rechargeable batteries obtainable.

Lithium-ion batteries have also been in the news lately. That is due to the fact that these batteries have the ability to burst into flames sporadically. It is not very common, just two or three battery packs per million have a problem; but when it happens, it is extreme. In some circumstances, the failure rate can rise, and when that happens you end up with a worldwide battery evoke that can cost manufacturers millions of Rands. So the question is… what makes these batteries so energetic and so prevalent?

Lithium-ion batteries are very popular due to the fact that they have a number of significant advantages over technologies of today as the technology of today requires incredibly powerful batteries here are some of these advantages

They are usually much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight carbon and lithium. Lithium is also a highly reactive element, meaning that a lot of energy can be stockpiled in its atomic bonds. This translates into a very high energy mass for lithium-ion batteries. Here is a way to get a viewpoint on the energy density. A normal lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery. A nickel-metal hydride (NiMH) battery pack can store maybe 100 watt-hours per kilogram, though 60 to 70 watt-hours might be more emblematic. A lead-acid battery can store only 25 watt-hours per kilogram. Using lead-acid technology, it takes 6 kilograms to store the same amount of energy that a 1 kilogram lithium-ion battery can grip. That is a huge alteration.
They hold their charge. A lithium-ion battery pack loses only about five percent of its charge per month, paralleled to a 20 percent loss per month for NiMH batteries.
They have no memory effect, which means that you do not have to totally discharge them before reviving, as with some other battery chemistries.
Lithium-ion batteries can handle hundreds of charge/discharge rounds.

Lithium-ion batteries have played a huge role in the industries of today especially in the electrical vehicle segment. If only a battery could power an entire city, the possibilities of the future…
