What do you mean by "universal charger"? The closest thing to universal these days is USB, which will work, with the right cables/connectors.
It depends on the actual charger that you are using. Here are some universal type USB chargers that would work for the 3DS. http://www.dealextre...e-nds-dsi-18461 http://www.dealextre...s-dsi-psp-17983 http://www.dealextre...one-2g-3g-21303 You might want or need an adapter too...

With just the picture to go with, no, it won't work. Box says DS Lite, which uses a different connection.
