Greeting !

السلام علیکم

As you see in the above picture.
What came to Your mind?

Is it Time bomb?

استؑفراللہ
I am not a terrorist
I am a noble citizen of Pakistan
No, this is a power bank of capacity 20000mah that I brought from the store for 2900/-..
That I Repaired by myself,
are you ask what happened to the original one?
Well,
Let me explain. On A sunny day, on a sunny morning, I was sitting with my family.
While taking breakfast, I plugged my cellphone into the power bank.
Suddenly, it
started heating up; I hold it feared that it might explode.
Because all batteries are made of Lithium-Ion, which is considered flammable.
And can even take your life with others.
So keeping in mind, I throw it outside and believe me, it was a box-packed battery that I bought Ever.

I thought it would explode but rather when it cools down,
then I tear it down to check what's wrong with it?
Then I figured out the problem, that was, The wires used in construction was weak and made of wires that came with handsfree(painted wires)
which caused the short circuit.
I desolder the wire from the charging module, Removed all wires, and look to draz to see replacement module

It is the second module that I brought from draz, and I never prefer online shopping because we are always looted by our own Pakistani but due to disability, I take some time a cup of the curse.
and it costs me about 700/-
I solder it stick it to the power bank using a glue gun and wiring tape.
But then I realized that it does not have fast charging features that were labeled on the store.
It made me disappointed.
It was basic 10 watts charging module.
then I turned toward mega e-shop Peshawar payed them 270 delivery charges advance, and they send me this 3v quick charging module costing 450, so the total cost became 270+450=700/-

It means I spend more money on repairing; that is not good.
Sometimes it is not suitable for us to repair things by ourselves, No matter How good are we at repairing.
I am good at repairing, but I am sometimes handicapped it causes great trouble due to unstable body and hands movements.
But I am struggling hard to live and fight with my body without caring what people will say.
At the end of my post, I tell you some important points regarding batteries and power banks.

Tips to buy Batteries Poer Packs and Powerbanks

• All batteries Made up of Packets or cells that are enclosed in a strong box or packing to make it safe from the outside environment.
• Do not buy nonbrand self-made packs; It may cost Your life
• Make sure the battery pack has a warranty period, but our shopkeepers never give it
  The basic charging protocol is 5 and 10 watts; Power delivery is made through charging IC and Protocols; some of them contain simple voltage regulators that effects or destroy your battery. Heating up while charging is the main example of it, and the reason is explained
• Battery pack including USB ports must be shiny new and strong.
• All supporting protocols must be labeled on the box.
  that start from QC 1to QC5
• Wattage of power bank must be labeled on the box.

The point we must care about

• Do not throw it into the fire when it is dead because it is flammable.
• Do not open the pack with a sharp knife or screwdriver because if you ever try to do, it will explode.
• Do not use a local charger or a cheap one. This will damage and shorten its life
• All original chargers contain data set regarding voltage regulation, so use proper and original data cable so they can communicate and regulate voltage.
• Do not use it in bed because these are less trustable in safety measurements
• Stay away when it's hot or smoking because it is dangerous.
  *Do not purchase old powerpack thinking them cheap because lithium batteries tends to lose it power and capacity over time

I hope this will help you more in your life
