The capacity printed on the label is rarely the capacity you actually get — manufacturers use inflated mAh figures, low-quality cells, and inefficient circuitry that delivers a fraction of the advertised power. You buy a 20,000mAh power bank and wonder why it only charges your phone three times instead of six.\u003c\/p\u003e\u003cp\u003eThe 18650 Power Bank Battery Box from Elanique takes a different approach: build your own. By using your own 18650 lithium cells — the same cells used in high-quality laptops, torches, and electric vehicles — you know exactly what capacity you're getting, from cells whose quality you've chosen yourself.\u003c\/p\u003e\u003ch2\u003e8 or 10 Cell Configuration: Scalable Capacity\u003c\/h2\u003e\u003cp\u003eThe 8 or 10-cell configuration allows you to choose your capacity based on your needs. With quality 18650 cells rated at 3,000–3,500mAh each, an 8-cell configuration delivers 24,000–28,000mAh of genuine capacity — enough to charge a modern smartphone 6–8 times. A 10-cell configuration scales this further, providing exceptional capacity for extended travel or multi-device charging.\u003c\/p\u003e\u003ch2\u003eDual USB \u0026amp; Type-C: Universal Compatibility\u003c\/h2\u003e\u003cp\u003eThe dual USB output allows simultaneous charging of two devices, while the Type-C port provides compatibility with modern smartphones, tablets, and laptops that have moved to the USB-C standard. The combination covers virtually every device you might need to charge — from older USB-A devices to the latest USB-C flagships.\u003c\/p\u003e\u003ch2\u003ePortable Shell: Compact \u0026amp; Durable\u003c\/h2\u003e\u003cp\u003eThe battery box shell provides a compact, durable housing for your cells that is genuinely portable — sized to fit in a bag or large pocket without the bulk of a commercial power bank of equivalent capacity. The hasp closure keeps the cells secure during transport.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Perciron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCell configuration:\u003c\/strong\u003e 8 or 10 x 18650 cells\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e Dual USB + Type-C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Battery storage box \/ DIY power bank shell\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible devices:\u003c\/strong\u003e iPhone, Xiaomi, Huawei, universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e 18650 cells not included\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Elanique","offers":[{"title":"8 Slot White","offer_id":51555811000663,"sku":"14:173#8 Slot White","price":28.06,"currency_code":"USD","in_stock":false},{"title":"8 Slot Black","offer_id":51555811033431,"sku":"14:29#8 Slot Black","price":27.98,"currency_code":"USD","in_stock":true},{"title":"10 Slot White","offer_id":51555811066199,"sku":"14:193#10 Slot White","price":30.61,"currency_code":"USD","in_stock":false},{"title":"10 Slot Black","offer_id":51555811098967,"sku":"14:175#10 Slot Black","price":29.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/8463\/0103\/files\/8-10-18650-power-bank-battery-box-holder-portable-dual-usb-type-c-charge-shell-for-iphone-xiaomi-huawei-cases-electronics-186.webp?v=1778085639","url":"https:\/\/elanique.shop\/products\/18650-power-bank-battery-box-portable-dual-usb-type-c-charge-shell-8-10-cell","provider":"Elanique","version":"1.0","type":"link"}
