Many recent testimonies abound on social networks concerning an old Sony portable console, in particular the PSP (PlayStation Portable), which could present a risk of overheating, or even spontaneous combustion. This issue is related to battery swelling, a phenomenon observed by many customers. Just open the drawer where it is stored to check.
When PSP becomes dangerous
The current success of consoles like the Steam Deck has reignited interest in portable gaming, but older models like the PSP can pose risks. If you have a PSP that has been unused for a long time, it is strongly recommended to check the condition of the battery. Published photos show PSP batteries bloated and cracked, and in some cases, the pressure exerted even caused the back cover of the device to pop off, revealing a potential fire threat. Standard and Slim & Lite models are affected.
This is the account @VioletOkami on X who warned the community:
Do you own a PSP?
Pull the battery out and check if it is swelling. An alarming amount of PSP batteries are beginning to swell and even burst, causing fires.
I learned this and told my friend who has one. He pulled it out, and it was swelling.
Check yours, please.

Although this problem is particularly reported on PSPs, it is not exclusive to this model. All lithium-polymer (LiPo) batteries, widely used in electronic devices in the 2000s, are prone to swelling over time. This phenomenon is particularly risky for devices that have remained unused for a long time, because the swelling of the battery increases the risk of combustion if it is handled. The ideal time for Sony to relaunch a new model based on the PS5? The fans hope so.
In the event of a swollen battery, it is advisable not to attempt to remove it yourself to avoid any accident. It is best to go to a recycling center or to an approved professional for safe removal.
Finally, an iPhone with the free PPSSPP emulator is less dangerous and more efficient!
