There are MILLIONS of potential fiery deathtraps out there in every neighborhood, town, and city right now, in the form of electric scooter and electric bike batteries being charged indoors, using poorly maintained equipment and no supervision by their users. And on top of this already hazardous situation, many of these batteries and chargers are of subpar quality and extremely cheap factory-discard straight to discount wholesalers coming from Chinese factories that want to save money by selling defective products at lower prices instead of discarding them, taking the loss, and potentially save lives along the way. Anybody right now can be living in an apartment above somebody who is charging racks of ebike batteries off a home circuit, and that is insomnia inducing to the maximum.
