Ne ho ordinati due. Il primo mi è arrivato con solo i fili di tensione in uscita ma senza i fili di tensione in ingresso, che ho dovuto quindi saldare io a parte (vedi foto con i due fili di rame con guaina trasparente). La tensione di questo comunque esce correttamente a poco più di 12v. Il secondo mi è arrivato completo di tutti i fili saldati ma la tensione in ingresso troppo superiore ed anche variabile. Il multimetro segna da un minimo di 15.21v a un massimo di 16.80v. Se acquistate alimentatori del genere quindi vi consiglio sempre di testarli prima di collegarli subito al circuito interessato, per evitare di fare danni. Possono essere utili se si vogliono alimentare progetti direttamente a 220v senza usare l'alimentatore esterno, sono piccoli quindi utilizzabili anche per oggetti in miniatura. Però ripeto, accertatevi prima che funzionino bene.
