How do phone chargers work? (thin cable question)

In summary, the reason most outlet charges have two wires connected is because circuits need to be closed and loop back in order for electrons to flow and provide power. Phone chargers, on the other hand, only require one wire because they use inductive charging. However, most chargers are USB and have four wires in one cable, with two used for data and two for power. USB cables typically use 24 gauge wire for the power wires, which can handle up to 2A of current.

We're all told how circuits have to be closed and loop back to be able to have the electrons flowing and give things power, so is that the reason most outlet charges have two wires connected? If so, why are phone chargers only one wire, and how are they so thin?
Thanks!

They are NOT one wire, they are two wires in a small cable because yes, you need two wires (or no wires if you do inductive charging)

+1 Most chargers are USB and that has 4 wires in the one cable. 2 are used for data and 2 for power.

I believe usb uses 24 gauge wire for the 2 power wires which can just about manage to carry 2A.

Related to How do phone chargers work? (thin cable question)

1. How does a phone charger transfer electricity through a thin cable?

A phone charger works by converting the alternating current (AC) from a wall outlet into direct current (DC) that can be used by your phone. This is done through a series of components within the charger, such as a transformer and rectifier. The thin cable acts as a conductor, allowing the electricity to flow from the charger to your phone.

2. Why are phone chargers usually made with thin cables?

Thin cables are typically used for phone chargers because they are flexible and easy to handle, making them convenient for everyday use. Additionally, thin cables have less resistance which allows for more efficient transfer of electricity from the charger to the phone.

3. Can a thin cable affect the charging speed of my phone?

Yes, the thickness and quality of the cable can affect the charging speed of your phone. Thin or low-quality cables may have higher resistance which can slow down the transfer of electricity and result in a slower charging speed.

4. What is the role of the USB port in a phone charger?

The USB port on a phone charger is where the thin cable is connected to the charger. It allows for a standardized connection between the charger and your phone, making it easier to use the same charger for multiple devices.

5. Do different phone brands require different types of phone chargers?

Most modern phones use the USB standard for charging, so they can be charged with any charger that has a USB port. However, some phones may require a specific type of charger, so it is best to check with the manufacturer or refer to the phone's manual for compatibility.
