Crews took about 40 minutes to get the blaze under control. The woman is not believed to have been using the device at the time.

Charlie Pugsley, from the London Fire Brigade fire investigation team, said People assume e cigarettes are much safer than ordinary cigarettes, and in most cases they are.

The danger is that people sometimes use incorrect chargers, which runs the risk of over charging, which can potentially have explosive results.

We are calling on e cig retailers to ensure they are selling the correct chargers for the cigarettes.

As with all rechargeable electrical equipment, it s vitally important that people use the correct type of charger for their e cigs to prevent fires which can be serious and could even result in death.

The London Fire Brigade also said e cigarettes should never be left charging overnight or when residents are sleeping.

Advice was also given to keep them away from naked flames and for patients with lung conditions to keep them clear of oxygen cylinders.

Electronic cigarettes have soared in popularity because they can be used by smokers to get around the ban on smoking indoors and can also assist people trying to quit smoking.

The battery charged devices deliver a nicotine hit but without the harmful tar contained in conventional cigarettes.
