It is just about which one could be used continuously. 由我女朋友使用S2S經驗, 這選擇只是在於是否能持續使用.
When you used S3S, the heater would be held till re-charged 3-4 hours. 若使用S3S, 該暖爐在電力用畢後須放著充飽電(約3-4個小時), 才能再度使用; 所以可能要買兩個輪替使用, 才不至於還要挨冷受凍個3-4小時.
When you used SL1S, the heater could be soonly worked after changed 2 new batteries. However, it might be reduced the heater's life span. 而用SL1S, 當電池沒電後, 再換兩個新電池就能繼續使用暖爐, 而沒電的電池則可趁此空檔拿去充電; 只是這樣持續操勞SL1S, 加熱器使用壽命應該會縮短!
