It’s probably off gassing aromatics from the molded plastics parts. Anything aromatic (in an organic chem context) is possibly carcinogenic. Past that its semi-volatile phthalates and other possible additives and light volatiles that may be off gassing especially from the unit’s heat generation/dissipation.

Offgassing testing is common (think new car smell…Yeah unfortunately that’s carcinogenic too, but we’re testing for stuff now). I’m pretty surprised they didn’t either invest in the right types of plastics that wouldn’t have potentially toxic emissions…unless they did and didn’t care until someone noticed and spread the word.

NPR is dope yo. They do good shit.

Reverse engineering to determine safety is what UL does. If anything here, the charger needs to account for fucked batteries with fail-safes but as long as the batteries are fine, it shouldn’t be a problem

Def not UL Listed

Spite! Spite is the word of your undoing!
