Dell D/Port Advanced Port Replicator 2U442

After ordering here and receiving this item (from Dell Direct), I missed the fine print. But the copy above *does* say that you need a PA-10 type power supply. As received from Dell, the item came with absolutely no documentation (or even an invoice for that matter.) So here I go ordering another $25 power adapter in order to use it. I'll be back if this isn't great.

and charge as needed, so i don't have to futz around trying to make sure i find the right one

Works just like the expensive one from Dell. No more fumbling with the laptop in the morning or evening. Just disengage and go. Thanks
