3 things that can make your Power bank explode

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.

    Also keeping it in the sunlight for too long can make it very hot which can also lead to an explosion.

    So my emoji portable charger exploded 20 minutes ago. But I didn’t over charge it I haven’t charged it in 2 days because the cord I was using broke so I was going to buy a new.I woke up to the smell of smoke and a hissing sound so I threw outside and it exploded.I don’t know how this helped.
