cosa ne pensate?
Trovo molto bella la funzione di avere il power bank integrato con ben due porte usb...ed ha anche un connettore a 12 v per esser caricata VELOCEMENTE in auto.
credo che quindi sia meglio della Acebeam K60 , non posso esprimermi sui driver e qualità costruttive...... ma almeno a vederla coi' ed in quanto a funzioni questa lumintop è il top del top......
