How do I know if my battery charger is working and how to fix it!

 Chargers play an important role in all rechargeable devices. They help us launch these gadgets so that we can use them remotely. But they can fail like any other electronic device. We’ll discuss how to use your battery charger, what to do if it doesn’t work, and what’s keeping them from working. Let’s have a look!

How do I use my battery charger?

Connect correctly

One of the most important things you should pay attention to when dealing with a battery charger is the connection. Make sure the battery terminals are connected correctly. If it’s a phone, insert the tip into the charging port. Do not charge with force, otherwise the terminals will be damaged. Once they are damaged, you may need to replace them as they are almost impossible to repair.

Compatible Devices

Battery chargers are only available for certain models. So it is important to check if the two devices are compatible. Otherwise, you are at risk, as wrong compatibility could lead to accidents such as explosions. If you’re not sure about compatibility, open the manual and read the capacity and voltage. This will give you a clue as to whether they are compatible.

Turn off the device

If you want the battery to charge fast enough, you should turn off the device. However, this is not required, but highly recommended. Or you can reduce background processes so the battery can charge quickly.

Plug into a safety socket

If the outlet is wet or overloaded, it could damage your charger, battery, or both. Battery chargers generally require higher voltages than other devices. So if you overload the circuit, it could cause an accident.

What do I need to do if my battery charger is not working?

diagnosis

When the battery charger is not working, the first thing you need to do is to diagnose. This will help you identify the problem. First check to see if your LEDs are on. If the light is on, your charger is fine and the problem may be with the battery or the device you’re charging.

Clean the terminal board

Use alcohol to scrub rust off batteries, laptops, or phone terminals. If those terminals are rusted, then your battery charger won’t charge. Now dry the terminals and insert the battery in its original position.

buy another

If the cost of repairs outweighs the cost of purchase, it would be wise to buy another one. Some chargers lack spare components, so it makes more sense to buy another. If it’s a phone charger, then you can buy spate components based on what doesn’t work.

Some large chargers, such as car chargers or laptop chargers, come with a warranty. Therefore, you can return them to the dealer for replacement.

Replacing a USB, Head or Adapter

It’s easy to deal with some chargers that come in two parts. This is because both parts are not prone to spoil at the same time. So you can buy another USB and keep the headers to keep costs down. Conversely, if you’re sure the USB is ok, you can buy the headers separately.

If you’re dealing with a laptop charger, then you can buy the two components separately depending on which component isn’t good.

What’s stopping my battery charger from working?

short circuit

Some chargers stop working after a short circuit. This is because voltage ICs or other important components may be damaged. Therefore, shorting out sockets, device ports, or battery terminals is very dangerous. If you expect the charger to serve you for an extended period of time, you should avoid this type of outlet.

bad connection

A poor connection can also prevent your charger from working. Make sure your power supply has enough voltage for the charger to work. Also, if it has two components, they both need to be connected properly. Most adopters have an LED indicator that shows you when the charger is connected to a power source.

Dead battery/device

If the battery is dead, that means the charger won’t work either. For example, if you connect the charger to a dead smartphone or battery. Also, if the device dies, it will not indicate whether it is charging. So the charger may be ok, but the battery is dead.

low voltage

Another problem that can prevent it from working is low voltage. This can be solved by fixing the power supply.

Is the charging speed related to the length of the cable?

 USB is the power source for digital devices. For devices with built-in batteries, connect the data cable to the USB-AC adapter or move the battery to ensure power supply. Many devices such as smartphones and smart watches are connected once a day, so it is important whether the charging speed varies depending on the length of the cable.

USB charging speed may vary depending on cable length

In short, the charging speed of USB will vary depending on the length of the cable. This is because the cable made of metal has internal resistance. If the value is large, the voltage will drop and current will be difficult to flow. Longer cables tend to have lower voltages because the resistance is proportional to the length of the cable. The thickness of the cable is also important. Since the resistance value is inversely proportional to the thickness of the cable, the thicker it is, the more it can prevent voltage drop.

USB power supply (VBUS) is sometimes defined as 5V±0.25 by the standard. If the voltage drops beyond this range, the operation may become unstable, so it cannot be ignored. In other words, assuming all other factors are the same, a shorter cable has a better charging speed. Different from life, for USB cable charging, “thick and short” is better than “thin and long”. However, in addition to the length/thickness of the cable, there are several factors that affect the voltage/current, such as the contact resistance of the connector. No wonder there are reports that there are more than a few percent difference when measuring power loss between high-quality USB cables and non-quality USB cables.

If you want to shorten the charging time as much as possible, reduce loss, and improve efficiency, use a commercially available USB current/voltage detector to find a good wire, or use a reliable manufacturer/brand of high-quality wire, let’s choose. Because it is used every day, if you calculate it 365 days a year in ○, it may turn out that high-quality, high-performance USB cables are more profitable, even though they are expensive.

The difference between the power adapter and the charger, can they be used together?

With the development of society and the popularization of technology, more and more people are beginning to use electronic products. For example: mobile phone power cords, data cables, chargers, charging sockets, laptop charging cables, USB, etc. These can be adapters. Think about how to charge your mobile phone or laptop every day. Today I will explain the difference between a power adapter and a charger, what is an adapter, and the role of a power adapter. Let’s take a look!

What is the difference between a power adapter and a charger? Please be patient to know the answer after reading it!

charger
It is a device that converts alternating current into low-voltage direct current. The charger is a DC power supply dedicated to rechargeable batteries. It contains control circuits such as current limit and voltage limit to meet the charging characteristics. It usually charges the battery directly without passing through any intermediate devices.

The process of the charger is: constant current-constant voltage-trickle, three-level smart charging. Adopting the three-level charging theory can greatly improve the charging efficiency, shorten the charging time, and extend the battery life. The three-level charging adopts constant current charging, constant voltage charging, and floating charging for maintenance charging.

Power Adapter
A common power adapter in the market is a power converter that passes through a converter, a rectifier, and a regulator, and the output is direct current, which can be understood as a low-voltage regulator when it encounters a power source.
The power adapter is a small portable electronic device and electronic and electrical power conversion equipment. It connects the power supply with a line to the host. This can reduce the size and weight of the host. Only a few are built in the host device to integrate the power supply part, which is mainly considered Many factors such as volume, cost, or certification.

Power adapters are widely used in routers, telephone hosts, game consoles, language repeaters, walkmans, laptops, mobile phones and other equipment. Most power adapters can automatically detect 100 ~ 240V ac (50/60Hz).

The power transformer and rectifier circuit inside the power adapter can be divided into AC output type and DC output type according to its output type; according to the connection mode, it can be divided into wall type and desktop type. Each power adapter has a nameplate indicating the power supply, input/output voltage and current, and pay special attention to the input voltage range.

Let me explain one thing to everyone:
The transformer is made of silicon steel sheet. After the transformer is energized, magnetic flux is generated. Magnetic flux will generate force between the silicon steel sheets and produce a buzzing sound, which is normal. However, the excessively loud sound is not normal. There are many reasons: 1. The AC voltage is unstable; 2. The chip is damaged; 3. The turn-to-turn short circuit; 4. The component is damaged. By the way, the purpose of the adapter is to convert alternating current into direct current.
