This dock works with every single Dell E Series Laptop. It also works with every Precision model laptop made since 2010. It does not work with Vostro, Inspiron or XPS family laptops.
Let me demystify Dell Port Replicators a little. There are many configurations available but here's what it boils down to. Originally these docks were made with USB 2.0. We don't sell the older version. All the Dell docks we sell are USB 3.0. So that leaves us with just two port replicators. There is the E-Port and the E-Port Plus. The plus has more ports, that's it.
The last consideration is the AC adapter (if any) that you want. You can use the one that came with your laptop. If you only take your laptop on the road occasionally that is the best bet, nothing else to buy. If you are on the road with your laptop frequently buying an AC adapter is worthwhile. The easiest way to pick the right AC adapter is to look at the one that came with your laptop.
This is the less expensive version of the PR02X dock with USB 2.0 ports. Dock in excellent condition. Does not include PA-4e AC adapter. Here the more expensive version of the PR02X with more ports.
