Vtech - 80-002181 - Vtech AC Adapter 7.5V - 9V (compatible Storio) (Toy)
Storio purchased for my son. We had to constantly recharge the batteries, this adapter is quite useful. Only downside, the wire is not very long and it is fragile. My son has "played" with and he cut net! Luckily he has a grandpa handyman!
