I received the product within 48 hours of placing my order and at a fraction of the cost of a Dell product. I've had the replacement in use several times daily since I purchased it over 1 month ago and can report no problems so far.
The charger is the wrong wattage for the inspiron 1545 this means yes it will allow you to use your laptop while plugged in but does not actually charge the laptop. I ordered two of these as I am always needing a new charger and I wish I had spent a little more to get a lead that would actually charge my laptop.
