Why Do Cheap Chargers Not Work

Don’t let a cheap charger ruin your day – find out why they don’t work and what you can do about it. Read it now: Why Do Cheap Chargers Not Work

If you’re like me, you’re often tempted by the low price tag of a cheap charger. But the consequences of using a low-quality charger can be disastrous. And I’m not only talking apocalyptic levels of bad. Using a faulty charger can be as dangerous as trying to milk a cow with a fork.

In this post, I will look at why cheap chargers fail and which factors make them inefficient.

One reason why cheap chargers can be a risky gamble is their lack of quality control. Many use subpar components, which can cause voltage fluctuations or short circuits.

I once had a cheap charger that overheated and damaged my battery. It rendered the device unusable. This not only cost me more in the long run, but it also posed a massive fire risk.

As well as the risks of using cheapo chargers, they also tend to stop working. This is usually due to poor assembly or faulty wiring.

So Why Do Cheap Chargers Not Work

Here are a couple of main reasons for the issues faced by cheap chargers:

Poor quality components, lack of safety featuresOverheatingUse a high-quality charger with safety featuresFire, explosion, damage to device
Inadequate power output, poor designSlow chargingChoose a charger with sufficient power output and a reputable brandInconvenience, reduced battery life
Poor quality components, lack of regulationInconsistent chargingUse a charger with proper voltage regulation and a reputable brandUnreliable performance, damage to device
Poor design, lack of informationCompatibility issuesChoose a charger that is compatible with your device and has clear specificationsInability to charge certain devices, damage to device
Poor quality components, inadequate designShort lifespanInvest in a high-quality charger with a reputable brand and proper designInconvenience, need for frequent replacement

Quality and Performance Issues

The main problem with budget chargers is that they often use poor-quality components and lack proper safety features. This in turn leads to inconsistent power output. This inconsistent output can then cause your phone’s battery to overheat.

There are three main causes of this inconsistent output.

  • Firstly, cheap chargers often have bad capacitors, which can cause the power to go up and down.
  • Secondly, the transformers in cheap chargers are not well made. So they don’t work as well and can cause the power to be unstable.
  • And last, cheap chargers may not use the correct means to regulate the power. So they can give too much or too little power to your device.

Another factor to consider is the quality of the charging cable itself. A damaged cable with exposed or broken wires is sub-optimal. It can cause charging failures or potential safety hazards. According to MakeUseOf, cuts and bends are two common causes of cable damage.

But why are substandard parts used?

Manufacturers of cheap chargers often cut corners to cut production costs. An easy way to do this is by using low-quality components or skipping important safety features. Some cheap chargers lack filters and voltage protection. This can cause damage to a device’s PMIC (Power Management Integrated Circuit). In this case, it would stop the device from charging altogether.

Another area where manufacturers look to cut costs is in the workforce. In some cases, manufacturers employ unskilled workers or even underpay their skilled laborers. This affects the quality of work and leads to a less-than-ideal product. Using underpaid labor forces to assemble the chargers can result in errors and inconsistencies. But the need to continue to produce cheap chargers means a reluctance to invest in automation.

Potential Hazards of Cheap Chargers

Let’s talk about the potential hazards of cheap chargers.

Damage to Devices

While it might feel good to save a few bucks on a charger, it can actually harm your device. A cheap charger can lead to damage or malfunction in phones, tablets, and other devices.

This can include battery damage. In extreme cases, the battery may even explode. And with phones costing as much as 2000 bucks these days, is it worth the risk to save five bucks on an unbranded charger?

Electrical Safety Risks

When it comes to electrical safety, going cheap can be a big mistake. A cheap charger may cause burns or fires, as well as electrical shock or electrocution.

For example, a study found that 99% of counterfeit Apple chargers fail basic safety checks. This is enough to think twice about using a cheap charger. It can put our loved ones at risk.

Here’s a quick look at some of the difficulties with cheap chargers and cables:

The Importance of Certification

In this section, I’ll discuss industry standards and how to recognize certified chargers. These certifications mean that your safety is best protected.

Industry Standards

The industry has worked hard to create standards for chargers. These standards make sure the chargers are safe and effective. Companies like UL Solutions test and certify battery chargers to ensure their quality. When a charger meets these standards, it gets a stamp of approval.

If a charger doesn’t meet these standards, it can cause problems. For example, cheap iPhone chargers have led to accidents and injuries.

Recognizing Certified Chargers

Look for specific markings or logos on the charger. For instance, USB-IF certification shows that a USB charger has undergone rigorous testing. Keep in mind that this certification only covers the chargers, not the cables.

When it comes to Apple devices, choose MFi-certified chargers. This certification means the charger meets Apple’s strict guidelines for performance and safety. It’s a clear sign of a high-quality, safe charger.

The Benefits of Investing in Quality Chargers

Here are some of the benefits of going expensive.

A quick Charge.

It is undeniable that using the manufacturer’s charger is super quick. And we can see when we plug in our device the estimated time to full charge. I have never seen a budget charger that is quicker than the correct charger.

Protection for Your Device

Using a high-quality charger protects my devices from potential damage. Cheap chargers often lack essential safety features, like voltage regulation and filtering. Harmful electrical surges may hit my device.

Longevity and Reliability

Purchasing a quality charger means I can rely on it to work for an extended period. High-quality chargers are made with good materials that undergo rigorous testing. As a result, investing in a quality charger means I spend less replacing faulty chargers.


Quality chargers are often designed to be compatible with a range of devices. This means that even if I upgrade my device, I can still use the same charger. Cheap chargers may not work well with different devices. In extremis, they cause damage due to poorly designed connectors or compatibility issues.

Cheap chargers fail due to low-quality components and a lack of voltage regulation. These issues can lead to an inconsistent power supply. This causes them to damage the devices they’re meant to charge. Moreover, prioritizing safety is crucial. Cheap chargers pose risks that you should not overlook.

These days, I choose chargers that meet regulatory standards from reputable manufacturers. In the long run, this decision not only protects my devices but also ensures my well-being.

Before You Go
