Can Apple Watch use the same charger as iPad?

It has been more than three months since Apple officially launched its first smartwatch product, the Apple Watch. After using it for this period of time, netizens have mixed opinions on this smartwatch. Among them, the insufficient battery life has become the most dissatisfied aspect for many wearers. It is really too troublesome to use it every day.

With such frequent charging cycles, a question comes up: the official Apple Watch configuration is a 5W charger. Can we use a 10W or 12W charger to charge this smartwatch? Will it cause irreparable damage?

In fact, there are quite a few users who ask this question in the Weiphone forum, and the answers to this question are different. So let us summarize and analyze it today, hoping to provide some reference opinions for users who still have doubts.

First, let's take a physics lesson:

When the device does not malfunction or short-circuit, if the charging voltage is the same, the power of the device will depend on the current allowed by the electrical device, that is, power = voltage × current.

For example:

The power supply output voltage is 5V. When connected to a device with a maximum current of 1000mA, the power supply output power is 5W (1000mA×5V).

The power supply output voltage is 5V. When connected to a device with a maximum current of 2400mA, the power supply output power is 12W (2400mA×5V).

The power value marked on the charger we see is the maximum output power, but as for its actual output power, it depends on how much the charging device needs. As long as it does not exceed the maximum output power of the power supply, it is safe. It should be noted that when the power consumption of the device exceeds the maximum output power of the power supply, it will cause the power supply to overload, causing the device to heat up severely, fail to work normally, or even burn out instantly.

Regarding the choice of Apple Watch charger, zablun, a user of Apple products, wrote a special post saying that as a user of Apple products, you should learn to find the answer from Apple's official documents. As we can see from the picture above, the official instructions for Apple Watch clearly state that you can use "the power adapter used by iPhone or iPad", which means that as long as the 12W charger we use is not a counterfeit or inferior product, it will not cause any damage to the device.

It is worth mentioning that the question of whether the iPad charger can be used to charge the iPhone has also aroused heated discussion among Weiphone users in the Weiphone forum. Weiphone users have transformed themselves into physics experts and conducted various data analyses. They finally concluded that there is no safety hazard in using the iPad charger to charge the iPhone.

Finally, you can leave a message to share your views on using a charger that is not standard with the Apple Watch to charge your Apple Watch.
