What this claim means
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.

Overheating Scooter Chargers: A Growing Home Fire Risk
Published by Wawanesa U.S., the U.S. arm of an insurance company. The page is an insurer blog article, so it has practical relevance to how insurers talk about charger fires, but it is not a policy form, regulator statement, or loss dataset.
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.
