Type...Carbon Heater Thank you for viewing. TEKNOS Senju CH-305M Mini Carbon Heater No instruction manual or box included. I purchased this as a supplementary heater and have hardly used it, so it's in good condition. Press the top button to turn it on for quick heating. Press it again to turn it off. Very easy to operate! It has a safety device that turns off the power if the unit is knocked over. Please refrain from purchasing if you are sensitive to used items or are looking for a perfect item, as it has been stored at home. I plan to pack it compactly and ship it in simple packaging. Thank you. Senju CH-305M color: WHITE Heating appliance type: Carbon heater Electric stove heating capacity class: Under 499W
