phone charger for rapid charging

When you want to buy a new charger, you always wonder about how fast it can charge and how long will it last. The reason you at all times have this same question in mind is that whenever you buy a new charger you always buy the wrong one, without having knowledge. Mostly, it could be a poor quality charger that everyone likes to buy, in the name of affordability. But those charges aren’t durable as well they take longer to fully charge a device.

Well, the puzzle lies on volts and amps. Those two things should be matched properly before buying the charger. Failure to do so, the charger can cause damage to your phone. Usually, the chargers are just looking similar in such that you can end up grabbing without hesitation. However, it’s not that all chargers are created equal, despite the similarity. So in this article, you’ll get important guidelines that’ll help you to buy a correct charger.


Voltage is an electromotive force pushed by the power supply. The voltage output by your power supply or a charger has the potential to become disastrous. Therefore you must match your new charger as closely as possible. For instance, if your old charger supplied 20V, the replacement should also be 20V. It shouldn’t be high or less. Because if you use different voltages the battery and device can be damaged hence lifespan shortened. At least spend more bucks and get a charger that has the same volts.


Amperage is the power transmitted by phone while being charged. So the device takes as much current as it needs. Therefore if your old charger is 2.1A, the replacement should be 2.1A and above (e.g 4.1A). Many people think that amps are complicated, but it’s not that. What I can advise you is that when you’re buying a replacement charger, go for higher amperage; for the reason that it supplies cooler power as well as giving optimum charging time.

Precaution: If you buy a charger that has less amperage, there’s a high risk for a charger to get overheated and burn. In some cases, your device’s charging system can stop functioning until it is fixed. Also, the other issue is that less amperage can charge the phone slowly or drain the battery when charging. This is because fewer amps are not able to get enough power to supply the battery.

The fact of Charging a Phone

Voltage and amperage play a pivotal role in charging. They work with a battery of a phone which is an essential small compartment of chemical energy. When you plug your phone to charge, basically you’ll be increasing the rate of a chemical reaction inside the battery. And thus where the combination of volts and amps take place. Well, nowadays most phones include a Lithium-ion battery. In spite of the fact that components are different, the charging route is still the same. Only what you can do when charging is to make sure that polarity is not reversed. Because when they are reversed your device will be damaged. The term polarity has a positive pole (+) and a negative pole (-).

Warning: Types of Chargers that Aren’t Worthy Buying

When you get into an electronics shop to buy a new charger, don’t only be carried away by cheap prices. There are some chargers that are not worthy of buying at all. Those chargers can be noticed by faked logos or without the manufacturer’s label. For example, if the charger is “ORG” product (with capital letters), then you will find out the fake ones written “ORg”(with small letter g). All they do is to twist people’s minds a little bit. So it’s important to notice that before purchasing. In fact, those fake chargers don’t have precise measurements of amps and volts. They just design fake letters for power.

Summarised Questions

  1. What causes damage to the device?. Answer: Reversed polarity and higher voltage of a charger than the rate of a device can cause damage.
  2. What causes harm to the adaptor or a power cord?. Answer: Reversed polarity and lower current of a charger than the rate of a device can cause damage.
  3. What makes the device not to work properly but not causing damage?. Answer: Lower voltage and higher current of a charger than the rate of a device can disturb the functioning of a device.


In short, when you’re grabbing a new charger off the shelf, make sure that the voltage and amperage are matching. And make sure that connectors are matching in physical form as well as in polarity. Another thing that you mustn’t neglect is the spec sheet. By reading a spec sheet or manually provided, you’ll be ensured that the charger is perfectly matching your device or not.

Finally, you must consider the logo of the charger. Because there are plenty of fake chargers out there that can end up damaging your device. So it’s better to use reputable manufacturers, even though they are a bit costly compared to the fake ones.
