Folding electric cool bag worked brilliantly. Not too heavy in my case and chilled drinks perfectly for the beach. It even came with a selection of 2 & 3 pin adaptors.
Thanks for reporting back Stevieg. Sounds like one cool gadget.
New question: At the other end of the scale, does anyone know where (in the Algarve or mail order) one can buy real cheap simple cool bag ? Something one can use for a week and throw away. Under €10 is good.
Richard - we have one of the silver carrier type bags that you can pick up in Intermarche for a couple of euros - I think they are designed to take your frozen stuff home but they seem to work well enough as a cool bag (especially if you add a bottle of frozen water)
