Severin WK 3647: what works and what doesn't
What works well
- 115/230 V switching: the big advantage over many cheap travel kettles, works on 115 V grids such as in the USA too
- Complete travel set: two plastic cups and two spoons are included, ready to use straight away for coffee and tea on the go
- Stainless steel body: brushed stainless steel feels sturdier than a pure plastic body and survives transport better
- Insulated handle: the heat-insulating plastic handle stays touchable while boiling
- Overheat protection: according to the manufacturer, a safety cut-out against overheating is integrated
Points of criticism
- Only 0.5 litres: as with the sister model, one fill is only enough for about two cups, not an appliance for several people
- No documented wattage: Severin gives no power rating; at 115 V heating is also likely to take noticeably longer
- Front scale on one side only: the water level indicator is only at the front, not on both sides like some models

Build quality & everyday use
What carries the Severin WK 3647 in everyday use: 115/230 V switching (the big advantage over many cheap travel kettles, works on 115 V grids such as in the USA too) and a complete travel set (two plastic cups and two spoons are included, ready to use straight away for coffee and tea on the go). The weaknesses have to be stated honestly: only 0.5 litres. As with the sister model, one fill is only enough for about two cups, so it is not an appliance for several people.
If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.
