Work like a charm
Great product and good buy.
Excellent, got two of these and they work really well with my computer.
it is not easy to get the right power adapter. Searched by model number and finally got this one. It is solid and good.
Great replacement or spare cord
Great Dell Charger, Definitely Recommend
My laptop was always iffy on wanting to charge when plugged in,
which when on for a few months before it decided on not wanting to charge at all. It would then only work when it was plugged in. I eventually realized that it was the charger and that it needed to be replaced. I had the original one from purchasing my laptop about one year ago. Hoping this one lasts for that long if not longer as well.
