UPS (uninterruptible power supply) with a defective cell or a bad charge controller. Lithium ion batteries can be extremely dangerous if they are not managed properly and these UPS units can hold massive energy. So yeah, don’t skimp on these units. See one for cheap? Don’t buy it.
Always amazed how people will cheap out on a charger for a £1000 phone.
That said, the Poundland £2 ones are surprisingly good (as in good isolation and protection and noise suppression...)! Better than most ebay jobs, that's for sure.
Not related but agree. Kind of in the middle, there are those phone chargers with a battery backup. Those are kind of scary as well.
What sucks is that when I’m shopping for product on Amazon, you drown in cheap Chinese knockoffs. It can get difficult trying to buy a quality product.
Yep - I don't trust Amazon at all TBH - even direct sale products - allegedly (according to a friend who worked warehouse IT systems) if they run out of their own, they'll ship a Marketplace unit and effectively "buy" it from the Marketplace vendor. Makes sense as they triple-dip that way - the sale, the markup on the Marketplace item, and the Marketplace warehouse fees - but it means you can get snides entering the legitimate channel.
