Opening the Zojirushi SW-KA food flask after a winter walk in Dublin felt like bringing a hot home-cooked meal outdoors. What impressed me most wasn’t just the sleek design — it was how my soup was still steaming hot six hours later. Since then, this series has become my favourite recommendation for families, students, and outdoor enthusiasts across Ireland & the UK.
Available in 300 ml, 520 ml, and 750 ml sizes, the SW-KA Series offers something for everyone: a light children’s food thermos for school, a compact hot food flask for office or university, and a large soup flask for outdoor meals. Thanks to Japanese vacuum insulation, food stays hot (up to 68°C after 6 hrs) or chilled (down to 9°C after 6 hrs).
Why it’s perfect
Parents → the 300 ml size is ideal as a children’s food thermos for porridge, pasta, or fruit
Office workers & students → the 520 ml food flask for hot food keeps lunch warm until break
Outdoor lovers → the 750 ml vacuum flask food is perfect for stews, noodles, or a hearty flask of soup on hikes or fishing trips

It is far beyond my expectations. For the price I was expecting something plastic that I hoped would work. I fitted it to the back of my kayak and it now means I can travel to place I could not reach before. I am a bit elderly so this does not mean too far, just as far as the battery can last and my paddling can last. I would not think this 18lb one would drive a larger boat.

Amazing quality for the price
It arrived in about 3 days. I was expecting a light plastic motor but was amazed by the quality. I haven't put it on a boat yet but it runs fine on the bench.

A great rod for the money
A great rod for the money.I have only been out fishing with it once to try it out and it casts 10g lures very well.Blanked that day so am looking forward to seeing what it is like with a decent trout on the end of it.
