Let’s talk about phone charger safety for a minute. While I know it is convenient to leave your charger plugged into the wall at all times it is typically not recommended. Even when they are not being used they are constantly drawing power and this could lead to a small chance of a fire due to either heat buildup or short circuit. Although this tends to happen more when a charger is being used. Another way this can happen is if there is an excess amount of moisture in the air which can short circuit the transformer. Not only can this create a fire hazard it also wastes energy which in turn means you are paying for electricity you are not really using.
Should you want to leave them plugged in it is recommended to use a power strip as they work as surge protectors and you can turn them off when not in use. Another important thing to consider is when you are charging make sure you allow for adequate ventilation so they don’t overheat. It is not recommended to charge them under a pillow, on a bed, or on a couch.
