Possible Reasons Why Power Banks Explode

Published

on

Powerbanks help a lot, especially in a country where there’s no steady power supply but on several occasions these life savers have turned to weapons of mass destruction. Here’s how a powerbank could have killed my roommate.

It was a cool evening, I just finished talking to a friend on the phone. I was conversing with my roommate outside. A few minutes later he went inside the room to get his phone before I could say Jack Robinson, I heard the sound of an explosion as he fled from our room faster than gala sellers that haven’t been paid, flinging the gate open as he fled for his dear life. This happened in a matter of milliseconds or nanoseconds. I was shocked.

This was the culprit :

Different thoughts ran through my mind. Could there be someone in the room? Or did he see a ghost?….There was no power at the moment so it wasn’t a socket sparking. Well, I’m not the superstitious kind so I ruled out the possibility of him seeing a ghost. I went outside the gate along with a couple of our lodge mates who were startled by the sound. The reason for his escapade was a powerbank that exploded in the room. He was trying to pick up his phone from the table and the powerbank which was just beside his phone just exploded in front of him. The powerbank in question just costs N1,500.

I tried to understand the different things that could have happened. He could have been injured badly on his right hand or his face would have been burnt, the former would affect him badly since we’re writing our first semester exams.

Now the ultimate question is :

Why would a power bank explode all of a sudden?. I decided to make some research and here’s what I could come up with.

1.) Wrong Circuit Design:

The internal circuit design of the power bank can also be another likely cause of explosion. For a power bank a good circuit should have

Power protection( a mechanism that ensures that the battery stops charging once it has reached full capacity), Short circuit control and temperature control.
If it doesn’t have any of the above features, the chances of explosion is higher.

2.) Poor Battery Quality

Batteries are the most expensive parts of a powerbank. Most of the power banks found in the market are made from either Lithium-ion or Lithium-Polymer batteries, though the lithium-ion is a cheaper option.

Most Manufacturers in a bid to keep prices down tend to use Lithium- ion batteries to save costs. In the worst case scenarios, they go to the extent of using recycled batteries which increases the chances or likeliness of explosion at a later time.

3.) Improper Usage

Exposing power banks to high temperatures or humidity can cause explosions. Overcharging of power banks is wrong. Also spilling water on it or leaving it near a heated area, like under the sun can cause explosions.

Mercedes Benz Accused Of Using Car Tracking Software On Their Cars

Mercedes Benz Accused Of Using Car Tracking Software On Their Cars 18

If you thought privacy issues end on social media then you might have to think again. Top Auto brand Mercedes Benz has been accused of using car tracking software to monitor drivers who use their cars.

The secret car tracking sensors, were all built into all new and used motors sold by the firm’s dealers, to enable them pinpoint the vehicle’s exact location.

Mercedes has refused to say how long it has used the sensors and has insisted the sensors are only activated in “extreme circumstances” — when certain customers have defaulted on payment.

However it has admitted to sharing car owner information and vehicle location details with third-party bailiffs and recovery firms who repossess the cars.

British Ex cabinet minister David Davis has called for extensive investigation into the matter.

According to Davis, “This is not the first time big business has behaved like Big Brother — but it’s rare to be quite as deceitful as this, I have to question whether it is even legal to pass on information to other people such as bailiffs. I would think the relevant minister ought to look very closely at the legality of this procedure.”

British Human Rights Group, Liberty said Mercedes’ actions were disturbing and part of the “creeping growth of surveillance”.

Legal experts have also raised concerns. According to a legal practitioner, “Modern technology means our ability to keep personal information private is under threat like never before.

“Organisations that handle personal data need to be completely upfront about what they are doing. That Mercedes appear not to have been so in this case is concerning. Its customers may start to worry about what other personal information the company may be gathering, then passing on.”

Personally, I have always said that privacy in the 21st Century is more or less an illusion. Just when you think all your data is secure, then it hits you. Mercedes isn’t the first to do this, however their rivals BMW, Jaguar Land Rover and Volkswagen have all denied that they do similar tracking.

An investigation by The Sun months ago revealed that Amazon staff can listen to Alexa recordings of British couples rowing, discussing private family matters — and having sex.

Yes you read that line, having sex. I haven’t seen something as obnoxious and bizarre as listening to conversations and sex at the same time. I don’t know the perverted employees Amazon has employed but it’s not acceptable.

According To Mercedes Benz , the said sensors are not used to permanently track customers or access real time data. “When a customer chooses to finance the purchase of their car this way they sign a contract and agree to the location sensors in the car being activated in the event that they default or breach their agreement.

“This clause in the finance contract is in bold print, just above the customer’s signature.

“Locating the car is part of the repossession process and is not permanently tracking customers.

“It is only activated in exceptional circumstances where the customer has breached their finance agreement and repeatedly failed to reply to requests to contact us.”

Nevertheless, It’s actually good if you can track your car on your own terms and luckily I know a good car tracking service.

Posts on both pages has been entirely deleted – Apple’s move at shifting away from iTunes links, I guess.

Before this, there has been separate apps for music on its mobile devices, however, not available for Mac OS.

Relating to that, there is supposedly going to be an announcement for three separate apps for its music, TV and podcasts, and hopefully they’ll also be available for Mac Books.

We’ll just keep our fingers crossed for this and other big announcements at WWDC.
