This is the Iwatani RC-1500, a portable 3-way refrigerator. It's a product jointly developed by Iwatani and Electrolux. It can cool in three ways: AC100V (household outlet), DC12V (car cigarette lighter socket), and cassette gas canister (CB can). It is currently confirmed to be working. External dimensions: Width 50cm x Depth 41cm x Height 43.3cm Internal dimensions: Width 34cm x Depth 21cm x Height 33cm (approx.) Capacity: 20L (effective volume 17.5L) Weight: 12.5kg While regular portable refrigerators use a compressor, this refrigerator uses an absorption system, so there is no vibration noise. It comes with the instruction manual and ice trays. The interior is relatively clean. The exterior is old, so there are scratches and discoloration due to aging. (Please check the photos) The plug of the original DC cord melted due to poor insertion, so it has been replaced with a new plug. Please be aware of this. A refrigerator is a necessity for camping in the coming season! Thank you.
