What can cause a power bank to explode

Ever since I heard about   a power bank that exploded inside a car glove compartment  ,I've reduced the number of times I use my power bank. The phenomenon of my power bank exploding is terrifying and I know can lead to regrettable incidents.

“I advise the public not to leave any electrical gadget or power bank inside their vehicle,” the owner of the power bank that exploded says.This is after he left his power bank in the car exposing it to the 'heat' environment .Another victim,Omonso,talks of how his cheap unbranded power bank disappointed him."Last year my power bank exploded.Luckily no one was hurt.There was a deafening sonic sound before it exploded.My blinds got burnt.No more power bank for me."

What can cause a power bank to explode?

1)Exposing the battery to the unsafe environment.
Exposing the battery to unsafe environment  such as high temperature or humidity can cause the cheap unbranded power bank to explode.Rise in temperature has the ability to cut your battery life by half.

2) Constantly overcharging the power bank
Constantly overcharging the power bank may damage the batteries if the power bank is not equipped with quality power protection features.Remember when EE recalled all power bars.

3)Malfunctioned Overcharge prevention IC
A malfunctioned overcharge prevention IC  will cause the power bank to explode.

Some power bank dealers use recycled batteries on new power banks which may have an effect on the end user. Power banks built with cheap batteries could easily explode or start a fire.
To be safe,buy a branded power bank from a reliable and trusted vendor.

Why its advisable not to rub your eyes when you wake up

Biznerati 5th Edition

Have you ever woken up early in the morning only to swollen lips or eyelids??Well,there is  need to worry. You need to visit your nearest hospital as you might have been a victim of the 'Kissing Bug'.
Kissing bug has been present as from early as the 1880s.In 1889,The Washington post called it an epidemic on its headline. The chagas disease brought about as a result of  the kissing bug was killing many people as at the time.It

was presumed that in the event that you had swollen eye lids ,swollen lips e.t.c then you were suffering from the disease.
  It was an epidemic. This prompted a widespread witch hunt for the kissing bug.The efforts proved successful and they succeeded in purging the kissing bug.
However,in 2005  cases of  the kissing bug hit  again.Its very hard to know the time of the infection since it can take years for the chronic aspect of the disease to be realized. The bug emerges at night when the victim -to- be is asleep.

It then proceeds to deposits feces that contains the parasites on human skin. The parasites then enter the mammalian (human) host through the bug bite, or breaks in the skin or conjunctiva. Occasionally, the parasites enter through mucosal cells of the mouth or airway when ingested or inhaled.- adapted from 


It's advisable not to rub your eyes when you wake up in the morning since the rubbing effect may rub the deposit left by the bug  leading to the parasites finding their way into your bloodstream.
The parasites eventually enter  the bloodstream and lodge in  the muscular structure of the organs. The parasites multiply and eventually cause chronic symptoms related to the involved organ or organs that can include cardiac failure,arrhythmia that eventually leads to death.


Time to monitor closely your wall crevices.

LITTLE SECRET ABOUT YOUR POWER BANK

Remember a time i told you about my power bank 5600mAh  ?Well, i decided to put it to the test.
I charged it overnight 'cause the next day i was to go on a journey so i thought it would really come in handy. So i woke up next morning unplugged it and carried on my backpack since it was full.Connected my phone to the power bank and it started charging .I kept peeping at the progress and that's when i got shocked!
My phone had taken up to a mere 75% and the reading on the power bank was at it last (25%).My panic mode got activated .From the power bank specs,The power bank had a capacity of 5600mAh which means it should charge my 1800mAh battery to up to 3 times. What was happening then?Was i conned?The power bank went dead and my phone battery had now reached 85%.I was conned .It was phony.
   However, it take about 5-6 hours to fully charge it up yet it charges my phone for 1hour 30minutes. I don't understand this.
By the time of writing this I had fully discharged the charger twice thinking that maybe it should take a few full (dis)charging cycles in order for it to conform  to its advertised (5600mAh) level just like with many phone batteries but again there were no instructions with it so I don't know.
Ladies and gentlemen,here is the little secret about your powerbank that they don't want you to know.

THE ATTRITION POWER THEORY

Its about the 30% energy or power lost when the powerbank boosts the phone.When you connect your 5600mAh to your phone(1800mAh) via the USB cable provided.A 30% power is lost in the name of boosting.Power input from AC to the powerbank is 5v while powerbank output to my phone is 5.3V which means the powerbank 'stresses' a lot to get to reach the 5.3V mark and this uses a little amount of energy so as to reach the voltage mark.

NB:The attrition power varies with devices.Next time you visit a powerbank shop ask on the attrition power of the powerbank

THE ABILITY TO LEARN SOMETHING THAT IS COGNITIVELY DEMANDING DECREASES WHEN LISTENING TO MUSIC

Biznerati 5th Edition

I'm always fond of  listening to music while performing tasks. The act of listening to your favorite jam while performing a task can motivate you and even easen the task at hand.But recently I discovered something weird.

When I was reading (with music playing in the background)an  eBook I had downloaded from the rcg.org  ,I found it harder concentrating that I just closed the book minutes after opening it.This was rather strange. How comes when I was performing less cognitively demanding tasks like cleaning my room while listening to music ,I would get motivated to perform it effectively and efficiently?


Well,In 2010, researchers at the University of Wales Institute
showed that when adults were asked to complete a relatively complex task of recalling a series of sounds presented in a specific order, their performance decreased while listening to music.
The study concluded that your ability to learn something new that is cognitively demanding decreases when you listen to music.
The eBook I had downloaded from the rcg website was cognitively demanding.This needed my mind to be fully concentrated on the  new resource.Listening to music would drive away my concentration from the material and this would lead to my inability to read it.


That's why you'll find it easier reading old literature while listening to music since it's not cognitively demanding as compared to new material.
