Batteries over two years old or with over 300 charge cycles typically exhibit poor durability. Symptoms include intermittent charging, short runtime (minutes to tens of minutes), or inability to fully charge a phone—all indicating severely degraded battery performance. Additionally, the product does not support modification or soldering. After-sales service is not provided for issues arising from non-compliant batteries. The mainboard incorporates a reverse-installation protection chip. While installing batteries backwards will not burn the mainboard, the integrated spring contacts may be damaged if the battery casing is punctured, short-circuited, or connected in series (one positive, one negative). However, after correcting the installation, the mainboard will remain fully functional and will not burn out.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S88f802b5f0b24a73b0abb3a3aa989f27T.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S44cce9b0dce449e89ce11858739ffb92n.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S06ac8ba2cd534d70a7e448255469e7dfw.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S240de04187ca4f64a3a16f21e18ac6fd1.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S97215349f25a41d98d62ba63e459fade6.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sbf6ee8a3390144b8af9cedbeb334f482L.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S2caabac8baac47b197ea7dd39b5b75dao.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S16649df3daff41db93be46fe37e429beO.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Seaeef100e17f47a790c561605e5d7309o.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e","brand":"URBANCREW CO.","offers":[{"title":"Black","offer_id":44470364700765,"sku":"14:193#Black","price":16.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/1928\/5853\/files\/S88f802b5f0b24a73b0abb3a3aa989f27T.webp?v=1779574734","url":"https:\/\/12wcir-ik.myshopify.com\/products\/transparent-4-port-22-5w-fast-power-bank-solder-free-4-cell-21700-battery-case-portable-pd-battery-storage-box-with-outdoorlight","provider":"URBANCREW CO.","version":"1.0","type":"link"}
