The boards have enjoyed an explosion in popularity recently, with Justin Bieber, Chris Brown and Kylie Jenner just some of the celebrities snapped on them.
It is thought around half a million people in Africa have bought the self-balancing boards as gifts.
What Are The Dangers?
Some models have been catching fire and blowing up, which is believed to be down to many having non-compliant UK plugs without fuses.
This increases the risk of the device overheating, exploding or catching fire. Some hoverboards’ cut-off switches failed.
Chargers, cabling and batteries were also found to fail safety standards.
Carol Helen Garrett, National Trading Standards principal officer, said: “The main hazard is in the board itself.
“The cut-off switch which should activate when the lithium battery is fully charged often doesn’t work.
“That means that the battery continues to charge, it overheats and there’s a significant risk of an explosion or fire, which is going to have devastating consequences and we have seen that in recent reports.
