Can a power bank explode without any triggering factor?

A good power bank wont explode if there’s no problem with it. This is explained by the law of inertia.
Newton's First Law of Motion (law of inertia) states that a body at rest will remain at rest unless an outside force acts on it; and a body in motion at a constant velocity will remain in motion in a straight line unless acted upon by an outside force.
But, is it likely that there won't be a triggering factor (outside force)? Well… I guess not. 

Every electronic gadget has a potential risk of explosion. Especially if used inappropriately. Even if not used, it is important to understand what could be a ‘smoking gun’ because it can still explode. I once saw on the news some years back how a house in the USA was totally burnt during a normal day. Investigators found that the fire was caused by dead batteries that were left in a drawer.

The batteries weren't the problem. The triggering factor was contact between positive and negative ends and the ‘smoking gun’ was wire wool also left in the drawer. Wire wool conducts electricity and can easily spark a fire when rubbed against metallic objects.

4 factors that can cause power bank explosion

  1. quality of the power bank
  2. status of the Internal Control Circuit 
  3. improper usage or product abuse
  4. suffocation
It is therefore important to know how to keep and use your power bank appropriately. The basic information you need should be contained in the power bank user manual. There are other factors that I expounded on in some posts I feel are related to this question; which I think are worth having a quick look at:
  1. Is it true that branded power bank won’t explode?
  2. If the amp is too high on the output, will it cause a power bank to overheat?
  3. How to dispose old power bank or battery
  4. Is it ok to use a smartphone whilst charging it?
  5. How often do I need to recharge a power bank if I am not using it regularly?
