Verified November 2026

Which one do you have?

You need: 4.5V adapter such as the 74254

You need: A 3V adapter matched to the piece's mA. Lemax no longer sells these and suggests a local hobby store.

You need: The 3-output 4.5V 1000mA adapter, not the 74254

Cheaper aftermarket part

4.5V adapter listed for Lemax

4.5V DC, 550mA minimum. Barrel size and polarity unknown.

Check first: Check your piece dates from after 2006. Older ones may need 3V. Match the polarity symbol on your old adapter.

Exact part

Assuming 74254 is a 3-output adapter because aftermarket titles list it in their fit lists; Lemax's own number is the single-output 550mA unit.
