I have two laptops, one for work and one for home, both Dell but different models. However, the power pack was always interchangeable. Well, new laptops have just come out for work and of course the new laptop power adapter is smaller. I've played on it with similar products with mixed results and was pleasantly surprised. Not only does it work, it also has a replacement part! The only downside is that if you don't place the adapter on a table with enough slack and let it dangle from a table, lap, couch or whatever, it can put extra pressure on the stylus. I could see that leaving it on all the time would create a future problem, but as long as you're aware and don't let it, you should be fine. Works great and a lot cheaper than buying a whole power supply!
