Charging a cell phone is something we all do every day. No big deal, right?
Take these familiar scenarios, for example:
All pose dangers. Here’s why:
Whether you need a replacement or just want an extra phone charger, it can be tempting to purchase the
low-priced option rather than the higher-priced charger from the manufacturer. However, purchasing a
bargain charger could have disastrous consequences. Most of the time, these products are unregulated
and untested. Their components are often low quality and are not backed by a manufacturer’s warranty.
Only purchase charging devices and electronics from trusted sources and be sure they have been tested
or marked by a nationally recognized testing laboratory like Underwriters Laboratories.It’s also
important to inspect your charging cords for damage. Any cord that carries electrical power becomes
a fire hazard when it’s damaged and wires are exposed. As soon as you see damage to a cord, stop using it.
It’s safest to charge your devices on cool, well-ventilated surfaces away from flammable objects. A
well-ventilated spot will help prevent your device from overheating. Devices tucked under a pillow,
nestled on the carpet or resting on a bed or couch don’t allow for this. And, always unplug charging cords
when they’re not in use. Cords that are plugged in are constantly drawing power. If the cord isn’t plugged
into a device that power can be transferred to flammable objects, such as fabric, carpet or wood, and
cause it to ignite.
Once your phone is plugged into an outlet it becomes a potential electrical hazard. And, unlike a hair dryer or
electric razor — devices meant to be used in a bathroom — phones, laptops and wireless speakers are not
equipped with a safety mechanism known as a ground-fault circuit interrupter (GFCI), which shuts off power
to the device when it gets wet.
In the U.S., building codes require you to use outlets equipped with a GFCI in bathrooms, kitchens and other
household spaces where an electronic device might come into contact with water. Regardless of the type of
cord you’re using, if you drop your phone into water you could be electrocuted.
Avoid relying on extension cords when charging devices. Extension cords are not meant for long-term use.
If you need to plug in your phone in a more convenient area than is available, this may be an indicator you
need more outlets. Don’t make your electronic devices even more complicated than they already are.
Always stay plugged into safety when using a device’s charging cord!
