DELL Mains Adapter 45 watts (Dunblane FK15)

Can anyone use this please? It came with a DELL Laptop over a year ago, but was never used. I tried using it one day last week, then discovered it was the wrong adaptor for the laptop as my laptop needed a 65 watt one. I'd been sent the wrong adaptor and never realised. Lesson learnt! Just wondering if it's of any use to anyone, or else I'll set it aside for the recycling centre. Thanks for looking.
