Mr. Motorman plugged into a US outlet

When I do get Mr. Motorman if I live in the US, do I have to use some sort of adapter?

The voltage in Japan is 100 Volts and in the US is 120 volts

no you will be using batteries.  

There are versions that have a plug. The AA Battery needs to charge.

then get the version that doesn't require the user to plug the device into an electric outlet  The plugs from different region is different.  Unless you have an adapter, they cannot connect to your wall's electrical outlets.  

As for AA batteries, I get them at my local dollar store.  Wal mart sells a bulk around 30 pieces.  They are relatively inexpensive.

I don't know for sure but wouldn't it have a USB port and not a hard wired plug to a wall cord? That way you can use any wall adapter (wall to USB) in your country? Mine is the 2 AAA battery one like in Ucwepns video which is not an onboard rechargeable.

This was the AA I was talking about

This was the AA I was talking about.....

OK, so it's USB, so no worries. Just plug the charger into any USB socket using the cable provided, anywhere in the world, and you'll be Motoring.

I recall trying to tell you this in a previous thread:

I do want a Mr. Motorman but I would have to get a Transformer to plug it into.

Wrong. The Li-Po version (AA size receiver) uses USB, like RC helicopter/quadcopter batteries. You would plug it into a USB port.

There's no such thing as a Mr. Motorman unit that uses mains electricity like standard (and 12V/9V LEGO) model trains. Also, it's not a AA battery, but a receiver that replaces a AA battery in a drive unit and contains its own (non-replaceable) rechargeable battery.

That's what I was also talking about, it looks like an AA Battery but it's a reciever.
