Is it normal for a laptop charger to get hot?
A laptop charger becoming warm to the touch under normal use is expected, especially at higher wattages; it is a sign of a fault only when it comes with a burning smell, visible damage, swelling, sparking or a buzzing sound. This guide separates ordinary warmth from the signs that mean stop using it.
In short: Warmth under load is normal, even for a charger that feels quite warm at high wattage. A burning smell, visible damage, swelling, sparking or buzzing is not normal, and any one of them means stop using the charger immediately.

Why do laptop chargers get warm during normal use?
A charger converts mains power to the voltage a laptop needs, and that conversion generates heat as a normal part of its operation. Higher-wattage chargers, such as the 150W to 330W chargers used by gaming and workstation laptops, run warmer than a 45W or 65W charger because they are converting more power.
Warmth increases with load: a charger working under a full charge, or charging while the laptop is under heavy use, will feel warmer than one topping up a nearly full battery. This is expected behaviour, not a fault by itself.
What are the warning signs of a charger fault?
Stop using a charger immediately if you notice any of the following: a burning or melting-plastic smell, visible damage such as a cracked casing or exposed wiring, swelling or bulging in the charger body, sparking at the plug or connector, or a buzzing or crackling sound.
Any one of these signs on its own is enough reason to stop using the charger and unplug it. These are general electrical-safety signs that apply to any charger, regardless of brand.
How hot is too hot for a laptop charger?
There is no published temperature figure on aurevalhub.com for what counts as too hot, and this page does not state one. Use the warning signs above — smell, visible damage, swelling, sparking, buzzing — rather than touch alone to judge whether a charger has a fault, since normal warmth varies by wattage and is not itself dangerous.
What should I do if my charger shows a warning sign?
Unplug it at the wall immediately, let it cool without touching the warm parts, and do not use it again. Do not attempt to open or repair a charger yourself.

What do buyers ask about charger overheating?
Is it normal for a laptop charger to feel warm?
Yes. A charger converting mains power generates heat as part of normal operation, and higher-wattage chargers run warmer than lower-wattage ones. Warmth alone, without a burning smell, visible damage, swelling, sparking or buzzing, is not a sign of a fault.
What should I do if my charger smells like it is burning?
Unplug it from the wall immediately and stop using it. A burning smell is a fault sign, not normal charger warmth, and the charger should be replaced rather than used again.
Is a swollen or bulging charger dangerous?
Swelling or bulging in the charger body is a warning sign of a fault. Stop using it immediately, unplug it, and do not attempt to open or repair it.
Do gaming laptop chargers run hotter than standard chargers?
Higher-wattage chargers, such as those used by gaming and workstation laptops (150W to 330W), generally run warmer than a 45W or 65W charger because they convert more power. This is expected and not, by itself, a fault.
Where can I find a replacement or check a specific model?
For which charger to replace one showing a fault, see the brand compatibility guides: HP, Dell, Lenovo, ASUS, Acer and Apple. If the laptop is not charging at all rather than overheating, read laptop not charging: causes and replacement charger. For what separates an original charger from a compatible one, see is a compatible charger safe to use?
