Most quality chargers will have the options for both Large and Small Tamiya connectors, what I like to call "Gator Clamps" that look like this
, and sometimes a Deans end also.
If your using the standard wall charger I highly suggest you upgrade your charger as something so seemingly insignificant can ruin a battery. Ive been using a charger that seemed fine for a while, with then finding out its got a reputation as a battery cooker. If you are unable to upgrade for a while then I suggest you get an adapter, Male Tamiya large to Female Tamiya small. If you have some electrical solder and a soldering iron it can be simple, or if you are unsure or cant get the parts made you can order a ready made one from www.cheapbatterypacks.com
While your there you can look for a better charger
