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.
