laptop or phone charger (Bury BL9)

Hi I know this is asking a lot, but i need a charger as mine has decided to stop, all i have is the 5w type and they take 12 hrs to charge my chromebook and 6 to do my phone. i am looking for either the brick type for a chromebook, or just a plug in type with the usb socket, it just needs to be either 25 or 45w Thanks for reading this If anyone can help, i'd be incredibly grateful and i collect most times and places.
