    "這是一塊 4x18650 移動電源模組，板上絲印可見 Input（Micro-USB 輸入）、USB-A 輸出、ON/OFF 開關、3.3V 穩壓（U4/U5/U6）、鋰電池充電（U2）、鋰電池保護（U9/F1）、DC-DC 升壓（U7）等區塊。安裝 18650 時務必確認正負極，板上已有標示，裝反會燒模組。電池正常工作電壓 3.2V–4.2V。5V 輸出額定 3A、最大約 3.6A，實際可用電流取決於電池品質與數量；3V 輸出名義 1A。多路輸出同時滿載時發熱明顯，需注意散熱與電池內阻。螺絲孔為 M2.5。輸入端 Micro-USB 與 Type-C 的實際接法、各 3V/5V 排針的確切絲印與極性，圖上無法逐一辨識，接線前請以實物絲印為準。"
