I purchased this with the intention of putting it in a truck, but I never used it. It's compatible with both 24V and 12V. According to the description at the time of purchase, it's rated for -20° to 20°C, weighs 9.5kg, and has a capacity of 15L. Since it's unused and has never been powered on, I can't confirm these details... It also comes with a household power outlet plug, so it might be useful as a personal refrigerator in your room or somewhere within easy reach. It didn't come with a shoulder strap from the beginning. Shipping costs are to be paid by the recipient. I plan to use Yamato Transport. The size is likely "140". It's shipped from Aichi Prefecture. Use at your own risk. Immediate purchase is welcome. If you purchase it, I would appreciate it if you could contact me within 24 hours.
