What to Look For in a USB Car Charger

During a long car Charger trip, you might find yourself wishing that you had a USB car charger so that you can recharge the empty battery of your smartphone. Recharging your phone in your car is a lot better than having to stop by a motel so that you can recharge your smartphone's batteries. Therefore, it is best to purchase a USB car charger before going on a long car trip so that you can recharge your smartphone in case it becomes empty while on the road. Read these tips on what to look for in a USB car charger so that you will be able to get a reliable and effective car charger.

Dual USB Car Chargers

Dual USB car chargers are better than ordinary USB car chargers. A dual USB car charger has two USB sockets instead of one, so you can recharge two devices at the same time. If you are going on a long car trip with your family, get a dual USB car charger so that two family members can recharge their smartphones at the same time.

Fast Chargers

Many of the USB car chargers in the market are very slow in recharging mobile devices. It can take two to three hours for ordinary USB car chargers to charge an empty smartphone battery. Look for fast USB car chargers that can charge your mobile device in one to two hours so that you can start using your smartphone or tablet again as soon as possible.

Shockproof and Vibration-Proof

You may also want to look for USB car chargers that are shockproof and vibration proof because cheap car chargers sometimes lose power or gets unplugged from the cigarette outlet of your car when you drive over a bump or when driving on a bumpy road.

Compact and Lightweight

It is also best that you get a USB car charger that is compact and lightweight so that it will easily fit in your shirt pocket or handbag and you can easily take it out while driving.

A Great USB Car Charger

A great USB car charger that has all of the features listed above is the Vority Duo 31CC Dual USB Car Charger.

What are the of a portable charger?

Unlike those that occupy a bigger space, a portable charger is most preferred for its ability to be easily transported from one place to the other. When you have something you can easily carry around, you will be able to use it more effectively in any given place. This is in contrast with those that are less compact and therefore, they do not allow one to move with them around. If you want to enjoy everything, you have to consider the size.

The way your device works and the ultimate performance are key when choosing a top quality mini portable charger. It is definite that you want a charger that can serve you for a long time and by buying it, you will not incur several charges that are unnecessary such as those required for replacements when the devices get spoiled. You can tell them to test it for you to confirm whether it is the ideal quality you are looking for. Another way to prove this is by getting to a friend or any other client who is currently using or has used it before and ask them whether the device is worth buying. Let it be after they give you feedback that you will go ahead to make the final decision.

Every brand produced by a firm has to be maintained in a working so that it minimizes on the owner's spending. Some of these practices include appropriate storage and keeping it clean away from any form of dirt. However, there are some of these chargers which need special conditions for maintenance and this makes it expensive to the person buying them. Therefore, ask if there are other special maintenance conditions required and are quite expensive, do not consider buying it.

The fact that it is affordable does not necessarily mean that it has to be very expensive. A good device needs to be sold at an affordable price to encourage many people to purchase. If it is expensively sold, only a few people, most preferably of the high class in the society, will be able to purchase it. As you plan your budge, you probably have a certain amount which you do not want to spend beyond. In order to maintain this, it is necessary to select those that are at lower prices. Do not tie yourself to only one vendor but have several options from which you can choose. To buy Best Portable charger, you must consider all the above factors.

Tips on replacing your laptop ac adapter

laptops operate off of direct current (DC) energy. Standard household jacks, and almost all businesses in the US make use of alternating (AC) current. This means that all PCs need a special adapter (power supply) that will temporarily store a charge from the AC current to provide an even flow of energy to the DC input jack. These power supplies are composed of a multi-wire cord connecting to an AC/DC adapter, which then has a single direct-current cord that leads to the laptops DC input jack. If your laptop has trouble charging, or the light on your AC/DC adapter does not turn on, it has to be replaced.

Use the Internet to select the proper AC adapter for your notebook. And you can find a wide variety of brand laptop AC adapters here at  Hootoo.com.

Secondly, Use the information you get from the Internet search to buy the proper replacement power supply. The best deals are typically online or direct from the manufacturers, but it is more convenient to go to a retail store to get a replacement part immediately.

Disconnect your old power supply from the laptop. This includes the entire power cable and AC/DC adapter. You may be able to reuse the cords of your old unit, such as if they are longer.

Assemble the new power supply that you purchased earlier. The AC cord connects to the AC/DC adapter, which connects to the DC cord, which finally connects to the laptop.

Check the light on the AC/DC adapter is lit. This indicates that the power supply is receiving power. You should also check your Windows desktop in the lower right hand toolbar for a power charging icon; it will look like a battery with a lightning bolt flashing on it.

Types and Uses of Universal Power Cord

Last week I visited my friends home and forgot to carry my laptop charger while packing.So after working a while, my laptop's battery went down and I needed a power cable. That's when my friend came to rescue and gave me the most useful thing ever, a 'Universal power cord'.

Universal Power cords or adpaters, as commonly known as are devices that make it possible to connect a power supply to various devices in just about any setting. There are adapters for handheld devices, laptops, and even for various types of household appliances. The need for a universal power adapter usually comes about when an individual is traveling to another country, where the type of electrical outlets and the kind of power supply must be converted in order to function properly with the device.

One of the more common examples of a universal power adapter would be the universal laptop power adapter. Adapters of this type normally come with plug attachments that make it possible to connect the power cord to different configurations of wall outlets. Since various countries use different designs and standards for electrical outlets, anyone who travels to a foreign location is likely to need these attachments in order to be able to use the laptop without relying solely on battery power.

Along with making sure that the plugs are compatible, a true universal power adapter will also help to convert the type of current available within the country to a type that is compatible with the electronic device. For example, if a handheld device or laptop requires direct current to operate properly, but the individual is traveling in a where alternating current is the norm, the adapter will  for the difference in voltage and cycle of the electrical current. This makes it possible to use the device without damaging the parts.

Along with adapters for use by travelers, people who are living abroad for a period of time may also make use of a universal power adapter on any household appliance he or she is taking along. Adapters of this type can be used with stereo equipment or other expensive electrical items that the individual wishes to have access to on an ongoing basis. When purchasing adapters for this purpose, it is important to make sure the particular appliance will function properly with an adapter, since some electrical appliances will not work at full efficiency even with the use of an adapter plug to convert the power supply.

What's the best nicd battery charger?

We often get by announcements of new are said to offer very high energy densities, deliver 1000 nicd battery charger/discharge cycle and are paper-thin. Are they real?  Perhaps — but not in one and the same battery. While one battery type may be designed for small size and long runtime, this pack will not last and wear out prematurely. Another battery may be built for long life, but the size is big and bulky. A third battery may provide all the desirable attributes, but the price would be too high for commercial use.

nicd battery charger manufacturers are well aware of customer needs and have responded by offering packs that best suit the specific applications. The mobile phone industry is an example of clever adaptation. Emphasis is placed on small size, high energy density and low price. Longevity comes in second.

Compromises also exist on lithium-based batteries. Li‑ion packs are being produced for defense applications that far exceed the energy density of the commercial equivalent. Unfortunately, these super-high capacity Li‑ion batteries are deemed unsafe in the hands of the public and the high price puts them out of reach of the commercial market.

In this article we look at the advantages and limitations of the commercial nicd battery charger. The so-called miracle battery that merely live in controlled environments is excluded. We scrutinize the batteries not only in terms of energy density but also longevity, load characteristics, maintenance requirements, self-discharge and operational costs. Since NiCd remains a standard against which other batteries are compared, we evaluate alternative chemistries against this classic nicd battery charger type.

The to develop rechargeable lithium batteries followed in the 1980s, but failed due to safety problems. Because of the inherent instability of lithium metal, especially during nicd battery charger, research shifted to a non-metallic lithium battery using lithium ions. Although slightly lower in energy density than lithium metal, the Li‑ion is safe, provided certain precautions are met when charging and discharging. In 1991, the Sony Corporation commercialized the first Li‑ion battery. Other manufacturers followed suit. Today, the Li‑ion is the fastest growing and most promising nicd battery charger chemistry.

Harmonics and Uninterruptible Security Camera Power Supply

Harmonic pollution is a growing problem in and one that designers of power Supply continuity programmes and manufacturers of UPS (uninterruptible power supplies) cannot ignore. Typical harmonic problems include the distortion of mains power supply voltage, overheating of wiring, neutral conductors, supply transformers and switchgear and nuisance tripping of breakers. Harmonics can also cause disruption to equipment on the same supply and lead to random failures.

Harmonics are caused by voltage or current waveforms with frequencies that are multiples of the fundamental frequency, 50Hz (50 cycles per second). The multiples are always ordered in a specific sequence: for example, the 2nd harmonic is 100Hz (2x50Hz), the third 150Hz and the fourth 200Hz and so on.

Harmonics and total power factor – implications for UPS sizing. Harmonics are also closely related to power factor management – and another key aspect of uninterruptible power supply system design and implementation. The displacement power factor is only applicable to the fundamental frequency (50Hz in Europe) and therefore does not take into account the power factor generated by any harmonics induced into the mains power supply by the load itself (referred to as the distortion power factor and produced by the harmonics produced by non-linear loads). The combination of the displacement power factor and the distortion power factor gives what is known to UPS systems experts as the true power factor. When correctly sizing a UPS, an understanding of this is critical.

Mitigation of total harmonics distortion. Harmonics issues need to be addressed at the design stage of any power continuity plan. Not least, because consumers are responsible for the harmonic levels introduced into their three-phase mains power supply.

A UPS can sometimes be fitted with a harmonic filter (post installation) but this can be a costly and inelegant solution as extensive internal wiring changes may be required. For a transformer-based UPS, using a 12-pulse rectifier in place of a 6-pulse set will reduce the levels of THDi (total harmonic distortion). Coupling this with a passive filter will provide further reduction to around 4%.

For a transformerless uninterruptible power supply, THDi levels of less than 4% can be achieved by installing an active harmonic filter. However, levels as low as 3% can now be achieved by some designs whose rectifiers are IGBT (Insulated Gate Bipolar Transistor) based. This can remove the need for an additional active harmonic filter and simplify the UPS design process. Such designs are expected to become the norm: not only do they reduce initial costs, but they allow a smaller UPS system footprint whilst increasing input power factors.

A popular approach to reduce the effect of leading power factors on a UPS installation is to use an active harmonic filter with power Supply factor correction on the UPS output. This presents the UPS with a more acceptable load, but results in higher capital and installation costs, lower efficiency and a greater footprint.

Familiar territory for UPS manufacturers. Although many aspects of harmonics must be considered when specifying a UPS system, reassurance can be gained from the fact that this is familiar territory for UPS manufacturers such as Riello UPS. End users and their professional advisers can certainly be confident that this specialised aspect of UPS application will be thoroughly addressed during the modern consultative sales and specification process.

How to discern a Car Charger?

How to discern a Car charger depends on how its work performance, safety requirements and electromagnetic compatibility is.

Different types of batteries have different charging requirements, the parameters of a charger are mainly charging method, charge current, charge voltage.

(1) Charging method: how to charge is based on the constant voltage or constant current. Given the current lithium-ion battery, charger charging current with limiting constant voltage mode shall be adopted, that is, charging at constant voltage automatically converted when the charging at limited current to the limited voltage.

(2) charging voltage: specifies the maximum output voltage of charger.The charging voltage is depends on limit voltage of battery charged; when charging the lithium-ion battery with nominal voltage of 3.6V, the maximum output voltage of charger required is typically 4.2V (in fact, the phone is equipped with a lithium-ion battery with protection device, so the charger output voltage can also be slightly higher than 4.2V, but the voltage is not more than 4.5V in order to ensure safety).

2, electromagnetic compatibility For chargers products, the electromagnetic compatibility requirements mainly reflects in electromagnetic harassment. Electromagnetic disturbance is divided into conduction harassment and radiation harassment. the many advantages of switching power supply contribute to the switching power supply circuit for universal charger. But the switching power supply of high-frequency switching devices produces high-frequency harmonic signals. These high frequency signals propagate through the power terminal via the grid or via space radiation result in the electromagnetic pollution to the environment, troubling the work around electronic devices,even may cause serious adverse effects on human health and the safe operation of the grid. Therefore, in order to reduce the electromagnetic pollution to the environment, the power terminal (or interface terminal) disturbance voltage for the electronic products working and radiation disturbance field strengths shall be less than a certain limit.

Wrap your AC Adapter power cords Properly

Notebook power adapter work in a computer repair shop, so naturally, I see a lot of laptops. The thing that surprises me the most, is that people rarely have their laptop ac adapters wrapped properly. Many people have crude ways to wrap their AC Adapter power cords, or they don't wrap them at all, causing a big mess of spaghetti style knots and tangles.

The best way to protect your cables is to wrap them properly. In each step I show a different type of  Adapter.

This is probably the most common type of power adapter. It is a power laptop ac adapter, with either a large Velcro strap at the end of one of the wires, or a large rubber strap coming out of the side of the AC Adapter.   To wrap it, take both wires in one hand, and wrap both of them around the AC Adapter the long way. Keep wrapping until you run out of wire.

This is a less common type of AC Adapter, but still one that is used. It is a laptop power supply that has a small piece of Velcro at the end of each wire.  To wrap this type of power laptop ac adapter, take one wire and wrap it in a small figure 8 shape, or wrap it around your hand. Wrap the single wire until you get to the end then wrap the Velcro around the wrapped wire.

This type of power AC Adapter is usually used for small laptops and netbooks. The power adapter has no straps, and it is too small to wrap the wire around the AC Adapter.To wrap this type of power adapter, take one wire and wrap it in a small figure shape, or wrap it around your hand. Wrap until you have a little less than a foot of wire left.
