If you're looking for a charger for your A515-54-51DJ Series, take a look at the Aspire 5; It just doesn't match your model. I'm not saying this charger can't do the job, but it doesn't work with the A515-54-51DJ series as mentioned above. Also, I can't verify if this charger works or not, but to be sure, let's assume it works.
