膠柸有陣味, 瓷柸最好, 不過唔保暖, 我依家都係用 stainless steel, 用咗之後就只能裝咖啡, 飲乜都有咖啡味, 好似紫砂壺性質咁。

順帶一提, stainless steel 有好多 grades, 有啲好容易有 stain (氧化呱), 唔係咖啡漬, 洗嘅時候睇清楚。

老竇教落: 便宜無好貨 。 通常都啱。  幾蚊雞無乜机会好嘢, 多數暖唔到幾耐。 測試好困難, 信牌子喇, 用過嘅以 Nissan 同 Tiger 保温好。有一個「唔全面」嘅簡單測試方法, 就係裝一杯超勁濃盬水放佢幾曰, 如果有有点点就係流野。

I don't know how much mA provided by the USB, my guess wold be less than a hundred. The USB cable is simply not designed for higher current.

but who knows, they put everything to USb.

有, 以前我在 Starbucks 買過一隻, 高身瓷柸連塑膠盍, 設計用於 cupholder, 不過打爛咗。
