Game Boy Advance SP Power Pack Review

Game Boy Advance SP Power Pack / B0001XP25O I was never able to get this car charger to work so I think it was either a hack or something got damaged in the delivery process. The retractable cord is quite flimsy and delicate, so is it possible that something bent or broke at some point? I've tried the charger in several cars and with more than one computer, so I'm pretty sure it's a good connection on my part. I could try to buy another one but wish the price was a little lower.
