Guilty as Charged: Why your phone charger could be damaging your phone

Have you noticed that your phone has started to give up on life just hours after being charged? Is it so slow to charge that it makes you want to throw it out the window? Or is your phone charger not working at all?

Newsflash; you could be using the wrong charger! One that doesn’t provide enough juice to power your phone. Unfortunately, rummaging through your drawers looking for the first available charger won’t cut it.

Although you may think you’ve struck gold with a cheap phone charger, using it to charge your device could have disastrous consequences.

In this useful article, we’ll tell you how to identify a cheap and nasty charging cable from a superior quality branded product. 

We’ll also show you how you can pick the best charger for your device, and avoid frustratingly slow-charging phones, or worse!

Advantages of choosing a brand charging cable over cheap alternatives

Third-party options can let you down

If you’ve been tempted to try and skimp on your charging cable, think again! Ok, they may be pricier, but your phone is an incredibly expensive piece of technology, and it deserves the best.

Not to mention your health is at risk when you choose to buy a cheap third-party charger! They’re unreliable, potentially harmful, and because of their low-cost price, they’re clearly not built with longevity in mind!

If you buy a new, officially branded charger, you’ll be safe in the knowledge that it won’t kill your phone’s internal components or set fire to your home!

Not only that, but it’ll be built to last. It may seem more expensive to begin with, but it will last you a lot longer. Having to constantly replace cheap ones every few weeks will upset your bank account way more!

How can a cheap charger damage a mobile phone battery?

Thanks to cheap phone chargers being easily accessible, many device users have been opting to buy these inferior quality products. However, it may not be worth passing up the more expensive, branded chargers.

These cheap charging cables can seriously damage your phone battery! They can sometimes be classed as ‘faulty’, so it’s super important that you understand the risks and dangers to avoid causing any harm to your device.

Once your phone battery has been damaged, it may not be replaceable. If it’s been fried by a faulty charger it may be damaged beyond repair, which means you’ve got the task of forking out for a new phone! 

The problem is, these cheap and unbranded chargers are available in every convenience shop and online store you come across. It’s very tempting to buy a couple and stock up. But these products can potentially cause the following:

Fire Hazard

A cheap USB charging cable is normally considered a fire risk because it’ll be susceptible to overheating. If you’re trying to charge your device with one of these generic chargers, you risk starting a fire as they usually don’t contain any safety features! 


Before you think of snapping up that cheap and cheerful charging cable, keep in mind that it may not meet official safety standards. 

If the charger doesn’t have the right insulation installed, then all of those volts surging through it could give you more than just a nasty electric shock!

Damage to your device

If potential fires and electrocution didn’t deter you, then keep in mind that these inexpensive chargers could damage your precious phone!

Generic manufacturers have started selling their own version of Apple’s lightning cable. Unfortunately, these cheap models don’t contain anywhere near the same level of engineering as an Apple USB cable does!

If you charge your phone with one of these knock-off models, you risk frying the internal components in your device. 

Not only that, but they’re frequently manufactured using painfully low-quality wiring that isn’t covered properly. This could also zap you with a nauseating electric shock, not good!

How to tell the difference between brand & cheap phone chargers

Just by looking at two chargers, you probably wouldn’t be able to tell the difference, which is a bit scary! However, don’t worry, there are some differences you can look out for.

For starters, an official, branded charger will likely have the company’s logo on it. A generic one won’t have a name on it.

Another thing to look out for is how fast it charges your phone. If your phone is charging at lightning speed then you can be sure you’ve got yourself a bona fide product. If it charges at the pace of a snail, it’s likely a cheap knock-off!

Choose the right charger for your device 

Charging rates

When it comes to choosing the right charger for your device, it’s super important to remember that different size devices will need more powerful chargers.

For example, if you have an iPhone and an iPad, the iPad will need more power than the iPhone. If you use your iPhone charger to charge the iPad, it will take forever to charge!

Power source 

Once you’ve figured out the charging rate needs of your device, you’ll need to think about the power source. If you use a wall socket, there’s enough power to charge pretty much any phone. 

The USB port on your computer doesn’t offer as much power though. When charging your phone try to use wall sockets or even cigarette lighters as these will offer the most power. Try to only use USB ports if the situation desperately calls for it.


Using a questionable cable is another thing that can put a damper on your high power charging. 

A cheap cable will often work the same, regardless of whether you’re using a powerful wall socket or a less powerful USB port. A cheap cable won’t use the power that wall sockets offer, meaning you’ll miss out on the benefits of high-speed charging!

Charging port

Make sure you use a charger that’s compatible with your charging port. This will ensure you get all that fast charging goodness! If your current charger doesn’t seem to be giving off much power, try a different cable. 

When it comes to finding the right charger, it may take a bit of trial and error, so make sure you shop around so you get the best one.

If you have an iPhone, then it’s highly likely your device will have a lightning port. For this, you’ll need a compatible lightning cable as it will give you the best charging results! 

Luckily, lightning cables are included with iPhone purchases, so you won’t need to buy a new one! 

Final verdict

Ultimately, to get the fastest charge you need to pick a charger that has, at a minimum, the maximum amount of power that your device can handle. 

Another trick to getting high-speed charging is to always choose wall sockets over a USB charging port. 

Additionally, you could try charging your device using a USB wall adapter. This will give you a bit more power which is handy if you need to fast charge your phone in an emergency.
