I have heard that buying non-original mobile chargers damage the phone? How to buy a mobile charger – what factors should I keep in mind?

Well only thing is to make sure it is 5V and 2A or so.. or 1A is fine as well..

As long as it stays in that range it should be fine. 10 years ago it would make a difference but not now..

Problem with local stuff is quality control.. That 5V can be 8V then it wont be fine as it will burn out your phone..

Just buy form amazon or flipkart etc.. Make sure the reviews say they are good.. Those cheap Chinese ones are worse.. They try tricks and thats iffy here.. It works but maybe not work so good in rain.. If line voltage spikes so does their outputs etc..

To see the difference, open up a samsung or sony charger and count the number of components.. Should be around 50.. Now open up a cheap Chinese one.. Number of components is like 10.. The 40 missing components are used for safety and to prevent fires etc..

Well with a degree like that he should easily be able to design a RC circuit for 10 bucks that would do the job?

just buying won’t hurt, using might! 😝
depends on the type (quality, capability to handle variances) of components used and overall build quality.

having said that, ‘original’ is fluid term in the context.

back in Ericsson, Nokia days ..all their chargers were made by salcomp.com/products, a well known, reputed vendor who made really sturdy and long service life chargers for almost all.
the core product is usually brand made
most accessories and add on parts (even in small home appliances, kitchen use products) are simply contract manufactured by the most economical vendors.

i think we still have a few Salcomp chargers in our homes from back then. (mota pin, patla pin of Nokia).
those and old Moto Razr, Ericsson chargers still work.

=

by local, if you meant brands like ERD.. then no, those usually won’t damage.
however mishandling or output variances, fluctuations or damage from abuse or wear tear can make even OEM suppliedsupplied original chargers a risk.


once even an old ERD charger who often freeze the phone (Nokia X6) in call or when dialling.
later realised that thankfully the phone was trying to tell that it had failed.
(misuse while putting in wrong/tight socket by kids and internal components moving after falling, throwing.. made it give erratic output rhythm)
.
almost all chargers are sourced from OEM vendors. except few Nokia, Samsung, HTC facilities who make their own.. may be Sony too
just use a reputed make or get its output tested under trial conditions from some engineering student or shop.

4 year of Engineering isn’t only teach you to make RC circuits sir !
And that’s a basic questions which you find answers by ece/eee quorans

Long story cut short: Stay away from local mobile charger for the safety of mobile and the living beings around.

Ok so which one should I buy? Just a good rated Amazon charger?

If I’m in your position, I will prefer a genuine branded manufacturer like Lenovo Xiaomi Sony Samsung. I don’t believe in ratings as the users likely don’t know what’s inside.

Well my experience with these local chargers is that it won’t harm the mobile but they themselves stop working in less than a month either the adapter or most of the times the cable. So if you want to spend on another one too soon you can go with one.
You may not need to buy only the original manufacture one, but just go with the same specs one of either reputed/good ratings one from Flipkart or amazon with some warranty.
Just always make sure to use the mobile charger with a socket adapter with fuse. Even my original xiaomi one got burnt because of surge.

Better use with branded good ones

Let me give some more perspective here
Chargers typically involve stepping down the voltage down to 5V or 9V from 220V. Earlier days, the design is based on transformers which provide intrinsic isolation from high voltage, but right from initial Motorola, chargers are based on SMPS technology where they use little different technology to achieve the same output. Although there is isolation by another means here, in the name of reducing cost, they will exclude the “isolation” part and hence there will be some leakage current on the Ground path which comes all the way till the phone connector. This leakage current is not good for human safety reasons. Also because of this, the phones (touch part) may behave erratic while they are being charged with local chargers. Apart from this, the voltage regulation may not be stable due to sub-stranded components or jugad they do in the design to reduce cost.

The above information is not meant to scare the existing users, but to increase awareness.

Get a good charger , not necessarily the branded ones of Samsung sony or likes who charge a bomb.
There are many available in the market For Rs. 60 to Rs.100.

I bought a bunch of JIO-Fi’s when ever they are on sale to swipe the chargers smile they also come with the best cables I have found..

The fi’s sitting in a desk.. but I use all the rest every day.. They are only 1A but if I want fast charging I use original adapter that time.. But normally I use the 1A ones.. This is because of the constant power cuts and surges etc.. You dont want to burn out a rs1000 fast charger.. Since its being charged usually at night dont matter if its .5A or 1A or 2A.. They will get charged by morning..

I did think the SMPS OEM chargers would last but Sony, Ericson and Samsung says other wise.. They do last longer but not for the price.. After a while it got to the point of just taking along a power bank because the chargers would get burnt out every other week no matter which one.. But the OEM ones I can be sure dont catch fire..

I got a 2A charger from flipkart but after an year even here it starts making a humming noise.. Saying the capacitor is ready to blow.. It worked well and still works but I dont use it now. The JIO chargers have worked over an year now with no problems at all..

It can because local charges are not good in quality and the material used can melt or catch on fire. Your device can too if it is attached. Also, local charges are not guaranteed to work on certain power range and most probably don’t have any fail safe. So charging IC in your phone can get damaged. That’s what happened to one of my phone 5-6 years ago.

If you are using local charger in case of emergency only then it’s fine.

Instead buy a charger from good companies like boat, mivi, mi etc. They have good charges and in cheaper range too.
