As a kit, it provides the housing and circuitry necessary to safely combine up to six standard 18650 lithium-ion cells into a single, functional power bank. Its primary advantage is flexibility, allowing you to utilise existing 18650 batteries, commonly found in laptops, power tools, and other electronics, to create a reusable charging solution. The case features both Type-C and Micro USB input ports, each supporting a 5V2A charge, and delivers a consistent 5V2A output suitable for smartphones, tablets, and other USB-powered devices. With a compact form factor and a choice of colours, it offers a practical DIY alternative to pre-assembled power banks.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and white DIY 18650 battery power bank charging case kit for six cells\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US13\/1059\/2025-10-04\/original-image\/1620226150676.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis power bank kit centres on a hard shell case that securely holds the internal components and battery cells. The design prioritises a straightforward assembly process where the user supplies the 18650 batteries. All electronic components for managing charge and discharge are pre-installed within the case, requiring no soldering or technical expertise to set up.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe case is made from a rigid plastic shell that provides structural protection for the batteries and internal circuitry. This material choice offers a balance of durability and light weight for portability. The kit is offered in two colour variants, black and white, providing a basic aesthetic choice. The external finish is designed to be functional, with clear port labelling and a form that is easy to grip and carry.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe case measures 22mm in thickness, 76mm in width, and 150mm in length. These dimensions create a slender profile that is designed to fit comfortably in a bag or large pocket. The size is directly determined by its capacity to house six cylindrical 18650 cells in a specific configuration. It's important to note that these are manual measurements, and a slight deviation of 1-3cm may be present. This size makes it a portable solution, though its capacity is directly tied to the specifications of the six 18650 cells you install.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and white DIY 18650 battery power bank charging case kit for six cells\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US13\/1059\/2025-10-04\/original-image\/193459488150.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe primary use for this kit is to create a personalised, high-capacity power bank for on-the-go device charging. It is suitable for a wide range of scenarios, from daily commutes to extended travel, where access to wall outlets is limited. The ability to use your own cells means you can tailor the power bank's total capacity and potentially refresh its performance by replacing older batteries.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor events, fieldwork, or professional settings requiring extended periods away from power sources, this DIY kit allows for the creation of a power bank with significant capacity, depending on the chosen 18650 cells. Photographers, event staff, or tradespeople can build a bank that meets their specific power needs for cameras, comms equipment, or tools. The dual input feature (Type-C and Micro USB) adds convenience, as it can be recharged using more than one type of common cable.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eIn everyday home and personal use, this power bank serves as a reliable backup charger for smartphones, e-readers, Bluetooth headphones, and other gadgets. It can be assembled once and kept ready in a living room, car, or work bag. For households with multiple devices or for individuals who are frequent travellers, having a customisable power bank means not being dependent on the fixed capacity of a commercial product. It also offers a sustainable option by repurposing 18650 cells from other devices.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and white DIY 18650 battery power bank charging case kit for six cells\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US13\/1059\/2025-10-04\/original-image\/3520097831401.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe core value of this product lies in its customisability and reuse potential. Instead of buying a complete power bank, you purchase the case and provide the cells, which can be a cost-effective approach if you already have suitable 18650 batteries. It also gives you control over the quality and capacity of the power source.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eA significant benefit is the ability to reuse 18650 batteries. If you have cells from old laptop battery packs or other devices that are still functional, this kit gives them a second life as a portable power bank. Maintenance is straightforward: simply recharge the bank via the input ports as needed. The design does not require specialised care; standard handling for electronic devices applies.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eChoose this 18650 charging bank case if you seek a flexible, build-it-yourself power solution. Its support for six cells allows for higher capacity builds than many small commercial power banks. The inclusion of both Type-C and Micro USB inputs offers charging flexibility, a practical feature as the tech world transitions between connector standards. It is a functional, no-frills kit focused on the practical task of creating a reliable power bank from standard components, making it a sensible choice for DIY enthusiasts and practical users alike.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and white DIY 18650 battery power bank charging case kit for six cells\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US13\/1059\/2025-10-04\/original-image\/4742600409947.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and white DIY 18650 battery power bank charging case kit for six cells\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US13\/1059\/2025-10-04\/original-image\/483882245450.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black and white DIY 18650 battery power bank charging case kit for six cells\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US13\/1059\/2025-10-04\/original-image\/5748645748292.webp\"\u003e\u003c\/div\u003e","brand":"b1iedb-mh","offers":[{"title":"White","offer_id":54838985261385,"sku":"CJSJYDSJ00082-White","price":14.0,"currency_code":"GBP","in_stock":true},{"title":"Black","offer_id":54838985294153,"sku":"CJSJYDSJ00082-Black","price":14.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3643\/3225\/files\/193459488150.webp?v=1783797005","url":"https:\/\/hhomeenjoy.com\/products\/18650-battery-charging-case-diy-external-power-bank-kit-with-type-c-and-micro-usb-dual-input-5v2a-output-fits-6-x-18650-cells-portable-black-or-white-mobile-charging-bank-case-measuring-22mm-x-76mm-x-150mm","provider":"hhomeenjoy.com","version":"1.0","type":"link"}
