How to Choose Cell Phone Docking Station Chargers

Mobile phone charger can be divided into docking station charger, travel charger and car charger. Following I will introduce characteristics and purchase notes of seated charger:

Docking station charger is easy to carry and convenient to use which has been deeply loved by users. But now there are various kinds of brands of docking station chargers in the market and the quality is uneven. When you purchase, you should take note. When to choose and buy, you should pay attention to the following matters:

1 weight

Generally speaking, the heavier the charger is, more electronic elements the charger use. To a certain extent, it shows the higher quality of the charger. This method is the most intuitive, and also be more effective. When you choose and buy, you had better take several different brands and different types of docking station chargers. You should weigh in the hands. Once contrasting, the quality is easy to be compared out.

2 function

Docking station charger's function mainly depends on the use of IC. At present, IC has developed into the third generation. After the improvement of the first two generation IC, the docking station charger's functions are more perfect which use the third generation IC. But as the market competition is intense, many manufacturers often use second generation IC with lower cost to make docking station charger and to sell pretending to be the third generation IC manufacturing products. So, first you should know the functional difference of the three generations of IC. If the docking station charger uses the second generation of IC, every time charging, you should first put docking station charger plug in the socket. And until the completion of the self-checking, you can place the battery on the chargers holder, or the charges will appear mistaking judgment of the battery electricity. It will not normally charge. So when you choose and buy, you can be very intuitive to use a piece of electricity shortage battery to test the docking station charger which generation products the IC belongs to.

3 plug pin

Docking station charger generally is divided into two phases fixed pin and two phase/three-phase variable pin. When you purchase, you had better choose two phases and three-phase variable pin. It will be convenience in the future use. In addition, when you purchase, you should try to pull the docking station charger's pin. If it's very easy to be pulled out, you should not buy such products.

4 Calorific value

When the docking station charger is at work, its internal transformer will produce a certain quantity of heat. Generally speaking, the better quality the transformer is the lower quantity of heat the transformer produces. As long as the temperature of the charge produce below 30 ℃ in the work process and when you touch it with the hand, it is slightly fever but not hot, it can be regarded as conform to the standard. So when you choose and buy, you should choose several different docking station chargers and let them work for a few minutes, and then feel the calorific value, you should choose the product with a relatively low temperature.

5 production technology and raw materials

If the condition permits, you can also detach docking station charger to direct view its circuit board's manufacturing process, spare parts quality, welding technology and so on to carry out the quality identification. In addition, welding points of quality charger's circuit boards are uniform. Soldering won't touch a large piece of solder, and it will use more elements such as transformer, capacitor, transistors and other elements with larger volume. If the components are of good quality, the docking station charger's life will be not only long, but also the performance is more stable.

How to Choose Cell Phone Travel Charger and Car Charger

Travel charger

The volume of cell phone travel charger is relatively small which is easy to carry. So a lot of users use it. Besides some matters when you choose and buy docking station charger, there are other aspects need to be paid attention.

1 interface

When you choose a travel charger, the first thing you should pay attention to is that the interface should be able to perfectly suitable for mobile phone charge interface. Avoid by all means of choosing loose interface or binding interface travel charger. Interface loose will keep the cell phone receiving unstable currency and it may form a larger instantaneous electric current which will cause damage to the mobile phone motherboard; And bind interface is very easy to break cell phone charge interface.

2 structures

The interface line of travel charger is fixed in the transformer or separated with transformer. The advantages of the latter are when you charge for different types of mobile phone, you simply need to replace interface line which is convenient and economy. In addition, this kind of travel charger generally designs with the overload protection circuit.

Car charger

The cell phone car charger is used car cigarette lighter as power supply socket which will charge for mobile phone directly. As the voltage provided by car is low, so the car charger internal need to be equipped with overload protection circuit. It often uses model 34063 IC or model 2907 triode to realize protection function. And the difference between the above two kinds is that the front of the car charger plug has an insurance tube. When the current exceeds withstand range of overload protection circuit, the fuse will immediately be fuse. It will have the protection function. Of course, compared with the choice of travel charger, car charger adds an interface choice -the plug which linked with car should be firmly planted in the car cigarette lighter.
