Feature
Features Just 10 minutes on the stove, leave for work or play and return home to a delicious meal. Thermal cooker saves energy costs and preparation time. Simply place the ingredients in the inner pot, cover lid and bring to a boil on your stove (approx. 10 minutes). When brought to a boil, remove from stove and place in outer thermal pot. Thermal technology creates a convection effect by using the steam produced inside to circulate and continue cooking for up to 30 minutes and warms for up to 8 hours. Food is cooked in its own moisture and steam, so nutrients are preserved. Compared to a pressure cooker, thermal cooker is 30% more energy efficient.


Advantages:
– No overcooking or burning
– Energy saving
– Time saving: take the food with you on the road while it’s still cooking
– Easy cleanup
– Safer: cordless and non-electric

Tips:
– Avoid opening the lid: before the cooking is finished, avoid opening the lid to prevent heat loss.
– The fuller the pot, the more efficient cooking. With more food in the inner pot, the thermal cooker can hold the temperature longer.
– Make sure a full boil before placing the inner pot in the thermal cooker. Do NOT heat the outer thermal cooker on the stove.

LOADING...

The Sunpentown ST-50L is a portable, 5-liter non-electric thermal cooker that continues cooking after ingredients are brought to a boil on the stove and can keep food warm for up to 8 hours. It suits people who want to prepare a meal before leaving home and let it finish cooking in the insulated pot.

Recommended For

  • People who can bring a soup, stew, curry, or similar one-pot meal to a full boil on the stove, then want it to continue cooking without a power connection while they are away.
  • Campers, boaters, and other travelers who have a stove for the initial heating and want a portable cooker that uses retained heat instead of continuous electricity or fuel.
  • Cooks preparing a larger batch of liquid-rich food who can keep the lid closed and let the insulated pot retain heat until serving; Sunpentown says a fuller pot holds heat longer.
  • People who want to carry a hot meal after cooking and keep it warm for several hours without relying on an electric warming setting.

Real-World Use Scenarios

  • Start a soup, curry, or stew on the stove before a busy day, then place the pot in the cooker; it continues cooking without needing a burner and can be ready to serve later.
  • Make a hot meal for a camping or RV day: bring the food to a boil on a camp stove or kitchen stove, pack the inner pot into the cooker, and return to a warm meal without simmering it the whole time.
  • Cook dried beans or lentils with less time on the stove: heat them thoroughly first, then let retained heat continue the cooking; some batches may need another boil if they are not tender yet.
  • Bring a hot dish to a picnic or shared meal: the insulated cooker helps keep food warm after it leaves the stove, so it can be served later without plugging in an appliance.
  • Reduce burner time when making a dish that normally simmers for a long time: once the food has reached a full boil, move it off the stove and let the cooker retain heat instead of leaving the burner on continuously.
