Original 200W HP 859740-001(4.5mm * 3.0mm) AC Adapter Charger
[CAIEPO-HP-19.5V-10.3A-4.5-3.0-HU-1519]

I've been using it for a month now and works perfectly.

Great service and great costumer support.

If you're looking for a store to buy laptop parts from, this is a good one in my opinion. I had a problem with my package (laptop charger) and they found me a solution. This was my second purchase.

It Took a little more time than expected to arrive but great product (charger and battery) and client support is excellent.
