Product details:

Replacement AC Adapter Laptop Charger Power Supply compatible with Acer Extensa 5630-4250 manufactured and sold exclusively by Power4Laptops. Unlike many of the cheaper chargers, our chargers have overvoltage and overcurrent protection circuits built in, this means if you get a power surge a circuit in the charger will blow before it damages your Laptop. Power4Laptops chargers have also had Electrical Safety Assessment Tests conducted on them in the UK and have a valid CE Certificate which authorises them for safe use in the EU.
