Brampton firefighters are warning residents about the potential dangers of charging your smartphone after a fire in a home on Wednesday night.

Firefighters responded to the blaze at a home at the corner of Royal Salisbury Way and Gilmore Drive, in the area of Williams Parkway East and Highway 410, just after 6:30 p.m. for a report of a house fire.

When crews arrived, they found smoke on the upper floor that was coming from one of the bedrooms.

Thankfully, the fire was contained and working smoke alarms alerted the occupants to the flames and smoke. No one was injured.

Fire crews say it appears the blaze was started when a cellphone charging "on an auxiliary source" caught fire.

Fire believed to be caused by a cell phone charging on an auxiliary source. Pls follow manufacturers instructions when charging ^jc

Fire crews are warning residents to follow the manufacturers' instructions when charging a phone, and avoid using generic chargers that purport to be compatible with a number of devices.
