Full guide Is it valid advice to leave chargers unplugged from the device but plugged into the wall? Evidence: limitedAction-oriented guidance
What this option means
Recommendation
For ordinary home use, it is reasonable to leave a good-quality charger plugged in when it is not attached to a device, as long as it stays cool, undamaged, and from a reputable source.
Why this is reasonable
The main concern is not the mere presence of the charger in the socket; it is heat, damage, counterfeit construction, or misuse. If any of those are present, unplug and replace the charger.
Practical takeaway
Treat a charger like other small electrical devices: fine when normal, but not worth keeping if it looks suspicious, runs hot, or has frayed cords.
Evidence behind this option
The reasoning this option depends on
Evidence check
A normal charger left plugged into the wall is usually low-risk
Bottom line
A charger that stays plugged into the wall without a device attached is usually not the main safety problem people imagine. The meaningful risk comes from poor-quality, damaged, counterfeit, or overheating chargers, not from the mere fact that they remain in the outlet.
What the source set suggests
The Wawanesa U.S. article points people toward the real hazard: heat, wrong equipment, and hazardous charging setups. That fits the common-sense view that a decent charger used normally is generally low risk.
What this does not prove
This does not prove that every charger is safe in every home. It also does not replace technical measurements or electrical-safety guidance for standby power and long-term unattended use.
Key sources for this judgment include Overheating Scooter Chargers: A Growing Home Fire Risk.
That is enough to support a real practical judgment, but not enough to turn the claim into a universal rule for every reader or situation.

Used to support the narrow point that insurer attention usually centers on hazard, misuse, or negligence, not on a blanket rule against any charger left plugged in. It does not prove how any specific policy or jurisdiction will handle a claim.
