Chargers For Australian Standard

Charger "avoid pit" guide

 

The first point is power.

In the ring of charging power, we must have a concept that no matter how many charging ports there are, the total power of all the charging ports together is constant, and this constant power is the total power of the charging head you buy. If you compare the total power to a river, then each charging port is each stream that branches out, and regardless of the number and flow of each stream, the flow of the streams combined together must equal the flow of the river.

For multi-port charging equipment, high power represents the upper limit of charging power of the equipment, but high power is not necessarily the best. So, if the charging device is not necessarily high-power premise, it is better to pick charging head from other dimensions.

So, based on this premise, if the minimum charging power required for your computer is 65W, then buying a 65W multi-port charging head and only charging your computer is just enough. If you want to charge other devices at the same time, it will not be able to meet the 65W minimum charging power.

To emphasize this point, it is because there are some laptops set the minimum charging power, such as some brands of the minimum charging power of 45W, if you use less than 45W charger, it will only notify the charging, and the power is not increased.

In addition, there are some laptops that can be charged at low power, but the computer power consumption is greater than the charging power consumption, which can also lead to power loss while charging. So, be sure to choose the right charging head product for your device.

 

The second point is the single-port charging power.

Just now we said, high-power multi-port charging head of this kind of thing, pay attention to the power balance, that each charging port in use, charging power are equally divided? Not, this involves a product design problem.

There are probably two directions: the first direction is to let the charging head priority to ensure a high-power output, the other two are discarded, the benefits of this design is able to ensure that high-power devices such as computers and other high-power devices normal charging, but the remaining two holes of the charging power will be limited to a very low, only to the watch, the bracelet such as low charging power device use.

The other direction is the rainy day type, so that each charging port to ensure that the charging power of more than 20W, which can ensure that all charging ports can be fast charging, but a single port is too low charging power there is no way to ensure that computers and other high-power devices normal use.

We have just said that the higher the power, the higher the upper limit of the charging head, so the choice of higher power charging head is a possible solution to the problem, but the ensuing problem is a larger volume, more expensive. Take the 140W three-port charging head of a certain brand as an example, it can guarantee a power output of 100W+30W+10W when charging with three ports, and 65W+65W when charging with two ports.

In addition, there is another point to note that some charging heads have a certain power difference between the charging ports. Only specific charging ports can reach the highest charging power, and the rest of the charging ports are limited by the product design and can only reach part of the charging power.

 

The third point is that more power does not mean more practical.

It should be noted that blindly choosing a high-power charging head is not desirable.

Here we take the product as an example, this 65W gallium nitride charging head single C-port use can reach 65W high power charging, USB-A port can reach 36W charging power, and when the dual-port use, the dual-port power together is only 15W ......

This means that this charging head can only be used in a single port.

Another example is another brand of 65W gallium nitride three-port charging head, only one C port output can reach 65W, the rest of the C port is 20W, the A port is 18W, multi-port charging to ensure that the highest power charging 45W.

In addition, this problem is also found in many high-power chargers over 100W, but due to its higher power limit, this problem will not be so obvious.

Understand the manufacturer's charging strategy for their own charger products, and then based on the above three dimensions, we go to select the charging head will have a clearer direction, my personal recommendation is to prioritize the guarantee of a high-power charging port, to meet the needs of the necessary equipment to replenish the demand, and then go to consider other charging port.

In addition, with the continuous progress of technology, this multi-port charging head has been upgraded, such as multi-port charging head in the new access to the device will be all the devices will be disconnected and reconnected, this problem occurs because the charging head needs to re-recognize the number of plugged-in devices and redistribute the power, but in fact, this is for computers, cell phones and other devices to pose a hidden danger.

 

The new model of the charging head, through a variety of recognition technology, so that the new device plugged into the natural distribution of power, there will be no power outages and other situations.
