3 things that can make your Power bank explode

Over the weekend, we saw the news of how a power bank
exploded on the body of it's user. This happened while he was
charging his phone with the power bank in his pocket. We may
ask, Why? Why would a power bank all of a sudden explode?
You guys requested we do a piece on why power banks
explode, my curious mind was also yearning to learn this too.
So I hereby present to you: The likely causes of a power bank explosion.

1.) Poor Battery Quality
Batteries are the major components of power banks, infact
that's the most expensive part when you try to cost it
individually. Most of the power banks in the market are made
from Lithium-ion or Lithium-Polymer batteries, though the
former is a cheaper option.
Manufacturers, (in a bid to keep prices down) tend to use the
Lithium- ion batteries to save costs. In worst case scenarios,
some manufacturers go to the extent of using recycled
batteries. This increases the chances or likeliness of explosion
at a later time.

2.) Wrong Circuit Design:
It doesn't just end with the quality of battery. The internal
circuit design of a power bank is another likely cause of
explosion. For a power bank a good circuit design entails the following :

* Power protection: A well made power bank should have
power protection. This is a mechanism that ensures that the
battery stops charging once it has reached full capacity.
* Short circuit control: A good power bank should have it's
circuit fully insulated to prevent short circuit. (Short circuit
means touching of wires)
* Temperature control: The ideal power bank should have a
kind of temperature control such that once it hits a particular
temperature, it shuts down to cool off.
If one or more of these are not built into the power bank, the
chances of a likely explosion in the future are high.

3.) Improper or Wrong Usage
What can cause a power bank to explode could be traced to
us – the users. How do you handle your power banks?
Exposing power banks to high temperatures or humidity can
lead to what can cause explosion . Overcharging of power
banks is bad practice. Especially when it doesn't have power
protection like we explained above. Other bad practices
include spilling water on it or leaving it near a heated area,
like under the sun.

So now you know the likely causes of a power bank explosion.
Meanwhile be careful of dirt cheap power banks, also do not
use power banks in your pockets. Cheers.
