Griffin is interested in how different kinds of batteries and AC adapters work. He wants to get an adapter to convert something that runs on D batteries to use AA batteries instead because they are cheaper and we have more of them around the house. He knows how to use a universal AC adapter instead of batteries. Or if he buys a used toy that is missing the AC adapter he can find one that will work with it. He is very careful to read the labels and make sure the voltage matches what it's supposed to use. He does not like it when AC adapters get very hot. Dad makes sure that Griffin doesn't leave the chargers or AC adapters plugged in overnight or if no one is at home. Mom tells Griffin to always wash his hands after handling batteries or power cords.
Here's what Griffin says about the special battery charger he got from Grandpa:
One of my favorite devices I have is a supercharger. It can charge alkaline batteries which aren't normally rechargeable and nickel cadmium rechargeable batteries. But watch out for ticking batteries and never leave unattended while charging.
Recharging non-rechargeable batteries doesn't work very well even though the special super charger says it can do it. They don't hold the charge as long, and it can make them leak. It is even possible that they could explode. But wouldn't it be nice to put off tossing them in the trash/recycling?
