Well I don't think these are genuine Dell cables. I bought 5, they all worked right away, but now I have 3 left that work stably. The problem you will encounter is that the Dell system will not be able to communicate with your Dell PSU and thinks the PSU has "wrong power" and therefore refuses to use the full one provide charging power.

I left my old Dell XPS 12 9Q23 power adapter with a family member in another state so I was thinking about getting a new cheap power adapter. but I already had an old power supply with a big round plug. It looks like these adapters will work, so I could use the power adapter I already had at home. I bought these two packs which seemed like one of the best deals as I didn't need 5 or 6 packs. So far, so good. They work fine. I will update this review if it changes.

I have several Dell laptops for work and home and some old chargers that don't fit new laptops. It helped me use old chargers on new laptops. I even keep one in the car now in case I go out and need a charger. What a cheap way to reuse those old chargers. Now I have one charger on my desk, one in my car, one in my living room and one in my bedroom. Therefore I have power wherever I am. It helps me to make my life a little easier every day!

I've used them with 10 year old PSUs and 1 year old PSUs and haven't had any problems with matching or over current, burning laptops or anything horrible. If it's not clear from the description, they take the larger barrel tips and shrink them down to narrower barrel tips so you can use old PSUs with newer laptops (they also make the cable about a foot longer). I would guess the only downside I see is that older power adapters may not have the power to charge large laptop batteries meaning it…

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…
