It seems like a great idea to put the food in and keep it warm with the cable.
Ideal size for one serving.
It comes with a spoon that can be assembled and disassembled for eating and the cable.

The USB cable is thick, so the actual current flow is about 2A. After a few hours, when I opened it, it was about 64 degrees and felt hot to the touch. It’s a pretty good item. 👍
If you connect a weak USB cable at home or use an adapter that doesn’t provide 2A, the correct temperature may not be achieved. 👍 👍 👍

Ac電源を使う、調理もできるもっと高機能な製品は使っています。 価格も数倍高かったですが。 それと比較してこちらのメリットは、usb（type-c）で電源が取れることです。 加熱調理用ではなく、保温、再加熱用かな？でも、電子レンジで加熱したブロッコリーやニンジンなどの冷凍野菜を、顆粒のコンソメだしで煮て、スープにする、とかなら十分できそうです。
完全な丸洗いは危険ですが、コネクタ部分をカバーできるので綺麗に洗えそうです。 サイズ感も良く、ストラッブのつけ方にも工夫があり、低価格でも使えそうなガジェットで、実際に使うのが楽しみです！

This is a nice size while only weighing 320g. it’s only 10w so it’s more of a keep warmer than a warmer. that said, i tried it with some water and it gradually heated to 70c over 4-5 hours so it will warm things up eventually. i don’t think it’s capable of boiling water ever though. it’s easy to clean and has a little spoon in the lid. i’m happy with it.
