Have you ever misplaced or lost your charger before? To make this even worse, have you ever lost your charger while your phone’s battery is dying and no else has a spare charger? Good gripes! That must be a nasty situation to be in. A lot of us cannot imagine life without our chargers and for good reason too. So what are smartphone chargers?

A (smartphone) charger is a device used to put energy into a secondary cell (rechargeable battery) by forcing an electric current through it.

How do smartphone chargers work?
In the truest sense of the word, mobile smartphone chargers are not pure rechargers. They are more like AC/DC converters/adapters that supply a device with power (voltage times current). This power helps to reverse the polarity of a battery and push electrons out of the cathode and into the anode.


Types of chargers
There are many types of chargers in the market today. They include:

Simple chargers:
These chargers supply constant current to a battery continuously. It does not alter its current output at all. It just supplies a steady flow of current regardless of the state of charge of the battery. Simple chargers charge for longer and are slower. This is because they are set to output low voltages so as to ensure safe charging.
Simple chargers are also known as dumb chargers. They are inexpensive to produce and are sold for very cheap prices. These are usually the cheap generic chargers found sold by roadside vendors. If a simple charger is used without supervision, it will destroy a battery as it does not know when to stop charging. It will keep pumping current into a full battery leading to battery degradation, capacity loss and a shorter lifespan.

Fast chargers:
These are intelligent chargers that can supply a high volume of current to a battery during rapid charging phase in order to charge it quickly. It does this intelligently without damaging the battery’s cells. As soon as the battery gets to 80%, the charger stops fast charging and returns to minimum voltage.

Intelligent charger:
An intelligent charger comes with a built in CPU or microprocessor chip which helps it to monitor the battery intelligently. It can modify (increase/decrease) depending on the battery state and cut off power supply completely if need be.

Three stage charger:
These are intelligent chargers that can detect the state of charge of a battery and intelligently control the supply of current to match each stage. As stated in the previous articles, batteries charge in three phases. A three stage charger will give constant current to a battery for rapid phase charging, reduced current for slow phase charging and very minute quantities for trickle charging. Three stage chargers can either be fast or slow chargers.

USB chargers:
A USB charger conforms to the USB standard, has a USB A or USB C port and only outputs current in 5V. Nearly all mobile smartphone chargers and power banks in use today, conform to this standard. This has made it easy for consumers to procure and use chargers today, especially when compared to 12 or 15 years ago.

Intelligent charger like xiaomi Gan for 11 ultra is da bomb....according boss nerosky.....nice one atheistandproud.

even charger dey get CPU omoo

Thanks for this. Very educative.

Great write-up.

How I wish Op supported this info with pictures for better understanding. Don't know which category my charger falls into.

Does your phone take forever to reach 100% when it is at 99%?

Does it slow down after crossing 80%?

Then yes it is an intelligent charger.

If it charges slowly throughout from zero all the way to 100, then it is a dumb charger.

Now that I’ve heard of intelligent chargers,some chargers are unintelligent tbh.
The ones that will charge a phone for 6hrs
Like why did the owner plug it? You can’t tell that you should speed things up?

guy you wan kill me with laughter here

Op, what category of charger is d charger you put up there belongs?

That's a 33W Mi Turbo fast charger. Comes bundled with the Redmi Note 9 Pro, Redmi Note 10 and Redmi Note 10 Pro.

It's an intelligent three stage fast charger.

These are the kind of chargers that'll make you want to get a brand new phone, especially those 33W, 65W and Xiaomi's latest 120W fast chargers.
My goodness!
Nice write up baba nla.
Keep on educating those that don't know.
More grace onto you.

nice one sir

thanks for the enlightenment. Never knew all these

lol. Well, probably the phone don't support fasting charging. Sometimes it ain't the charger

Some brands will come with flash charge chargers, but will still charge for 7 hours.

6000mah my ass.

60hz refresh rate with 720p resolution pfft. gods of mediocrity.

Using the Camon 16 Premier over the weekend makes me understand the fast charge technology better. Good write up

Good write up. Very soon most phones will have to come with fast charge technology and also intelligent chargers. Tecno is already making the right move.

what about some chargers that you will plug to ur phone at 40% and u will come back to see them at 33% after 2hrs?

What do you expect from buying road side charger

The BOX and USB chord which is more important when it comes to fast charging?

I recently misplaced my USB CORD for my camon 16 PREMIER and I picked one of my formal phone's cord still the phone is charging at normal rate within an hour it's already up to 100% from 0 and sometimes it takes less than 30 minutes to get to 60 70%.

I don't know if I should still get the new follow come charger for it

I am very well aware of Fast charge technology and I have experience it with the Camon16Premier.

Then I have learnt a lot through this article, intelligent chargers!!!

nice info, talking about chargers that are fast, the fast charger of the Pova is something else

The charging brick but most phones using MTK's pump express won't fast charge without a supported USB cord.
