It's desperate to find something that can charge a smartphone, tablet, or laptop, but I'm not very particular about what type of charger connected.
Isn't there a lot of readers like that?
After all, as long as you connect the device to the charger, you will not be unable to use the battery, which is most important.
But not all chargers are made to have the same performance.
If it is a habit of charging with a USB port or outlet that can be used quickly from time to time, the charging speed may be much slower than the original performance of the device.
Basic knowledge of "performance of charger"
In most cases, the charger is composed of two parts.Charging cable and power adapter part.
The adapter is also called "brick (brick)", a part that is inserted into a square -shaped outlet.On the other hand, as you can see by the name, the cable is the part that connects the adapter to the device.
In some cases, charging does not require an adapter.
For example, when charging devices on another device (such as PC), or when charging with a built -in USB port.In the case of wireless charging, the charging pad plays a cable.
In general, cables do not affect charging speeds.It is the power adapter that affects the charging speed.
Some adapters have the ability to supply more power to devices than others.
The unit that measures this ability is Wat (W).If you look at the power adapter, this number should be written somewhere, such as "5W", "18W", and "30W".
However, this article does not cover a specific device dedicated charger.If you can only use the charger that you are using, you have to charge it.
The following is a device with a USB port.With these devices, you should be able to use various cables and adapters for charging.
Surprisingly difficult "optimal charger selection"
There are so many types of power adapters, so you can't easily identify the best one for your device.
In some cases, it is difficult to choose the optimal charger due to the circumstances on the device side.This is particularly noticeable about smartphones.
Apple has decided not to include a charger in the latest model of "iPhone" ahead of other companies.After that, other smartphone OEM manufacturers followed, which is a new standard.
Apple claims that this decision is a result of considering concerns about the growing environmental issues, but consumers without power adapters at hand have left their devices without charging.Furthermore, it seems that consumers who cannot judge are unable to judge which adapter to use for their favorite devices.
However, looking back on the past, Apple wasn't conscientious about this.
For many years, Apple has included a 5W adapter that is never high performance on the iPhone.Some people still use this adapter to charge the iPhone.
This is very disappointing.With a 5W adapter, it takes a lot of time to charge the iPhone.
Tips for charging the device at the fastest
In the case of a smartphone
All devices have an upper limit on current that can be supplied from the adapter.
However, there is no problem even if it connects to a stronger power supply than the setting.This is because the device does not flow over the upper limit.
For example, if a smartphone with a upper limit of 27w is connected to a 35W power adapter, it will be charged only at the maximum of 27W.So it's not dangerous.
Also, there is no danger even if it is connected to a power supply that is lower than the device setting.
In the case of the iPhone mentioned earlier, Apple introduced high -speed charging functions to "Phone 8", "iPhone 8 Plus" and "iPhone X", enabling charging at 15W.Nevertheless, the adapter included in these devices remained in the 5W specification.
It takes time, but this adapter can be charged safely.However, in order to fully utilize the charging function of the device, you need to buy at least 15W -compatible power adapters.
The most important thing is to check the specifications of the device you are using.
For example, the iPhone 8 Plus I use can charge at a maximum of 15W.In other words, if you use a 12W adapter, you will not be able to fully use the charging performance of this device.But if you connect an 18W adapter, you can charge the fastest as fast as possible.
On the other hand, "Galaxy Tab 7+" can charge 45W quickly.If you want to make the most of this charging speed, use a powered adapter with 45W or more performance.The less than this adapter takes a long time to charge.
For PC
That said, in some cases, it may be difficult to respond.
In a laptop like a MacBook, it is best to use a large -capacity adapter that comes at the time of purchase.
For example, a "MacBook Air" equipped with "M1" chip comes with a 30W adapter.
You can use a more compact USB-C adapter than this, but it takes time to charge, and if you are working on a load, the battery capacity will be reduced even if you are connected to the adapter.It is possible.
On the other hand, there is no problem using an adapter that is more than a machine charging ability.Computers are not accepted more than specifications.
To put it simply, in general, "adapters have never had high power supply capabilities."Even if you have high abilities, you will not harm the device, and the probability of charging as fast as possible will increase.
Convenient but slow "wireless charging"
On the other hand, wireless charging is convenient, but it usually takes longer than conventional charging using an adapter connected to the cable and an outlet.
In order to charge at the fastest speed, you must buy a wireless charger that supports high -speed charging (it also has a condition that if your favorite device corresponds to the standard).Moreover, it is not so fast even if it is supported.
Unfortunately, even if you connect a high -performance power adapter to a wireless charger, you will not be able to charge at a speed that exceeds the highest performance of the charger.
In that sense, the wireless charger can be said to be a bottle neck similar to the device itself.If you reach the maximum speed that is determined for each charger, there is no way to speed up any more.
