Could your charger be a fire risk?

Fire Safety 12/11/2026

Many of us use chargers every day to charge our phones, laptops, e-bikes, e-scooters and other devices without giving it a second thought.  

All these devices run on lithium batteries, but did you know that these batteries can lead to home fires if they're not looked after properly. 

What can cause battery fires? 

Damaged or faulty lithium-ion batteries can be a fire risk. When used correctly, the risk is low, but it's important to recognise when something is wrong. 

Look out for these warning signs: 

  • The device feels unusually hot when you're charging 

  • You can hear a hissing sound 

  • Your device isn't charging properly 

  • There's damage to the casing 

  • Noticed swelling on the charger or it's leaking liquid 

If you've noticed any of these signs, stop using the battery immediately and dispose of it safely at your nearest recycling point for electricals. 

E-bikes and e-scooters: an increased fire risk 

According to the West Midlands Fire Service, the number of e-scooter and e-bike fires has doubled in recent years. These fires can happen quickly, create huge amounts of smoke and make escape routes unsafe. 

Just like all rechargeable devices, e-scooters need charging and this is when batteries can potentially set on fire. 

Please remember, if we find any e-bikes or e-scooters in communal areas, we'll have to remove them. 

If you do own one, here's how to safely look after your e-scooter and e-bike: 

  • Always use the same charger that came with your e-scooter 

  • Only charge your e-scooter whilst you're at home and awake 

  • Don't leave your e-scooter or e-bike in communal areas, stairways or in escape routes 

  • Let the battery fully cool down before charging it 

  • Only buy e-scooters from trusted retailers  

  • Check your battery regularly

How can I keep my home safe?
