What is Diy Power Bank Case?
A DIY (Do-It-Yourself) power bank case is an empty enclosure designed to house the internal components of a portable charger. It allows you to build your own power bank by incorporating Lithium-Ion or Lithium Polymer battery cells (typically 18650 or 21700 cells), a charging circuit board (PCB), and necessary protection circuits. These cases typically come with USB ports (USB-A, USB-C) for both charging the power bank and discharging power to external devices like smartphones, tablets, and other gadgets. Common models include cases with built-in LED indicators to show battery level. The cases are made from durable materials like ABS plastic or aluminum alloy for protection and often include features like overcharge, over-discharge, short-circuit, and temperature protection. Some popular brands of charging PCBs compatible with these cases include those from TP4056 and other generic charging circuit manufacturers. The DIY power bank case is a cost-effective and customizable solution for anyone needing portable power.
Key Features & Specifications
Our DIY Power Bank Cases boast several key features. They are typically constructed from durable ABS plastic, providing excellent impact resistance. They feature multiple USB ports, including USB-A and USB-C, with support for fast charging protocols like 5V/2A and, in some models, Quick Charge 3.0. Dimensions vary, but a common case size for 4 x 18650 cells is approximately 100mm x 80mm x 25mm. Most cases include a digital display or LED indicators to show the remaining battery percentage or voltage. They often include built-in protection circuits, such as overcharge, over-discharge, and short-circuit protection. Compatibility is usually with 18650, 21700, and sometimes even AAA batteries, depending on the case model. They are easy to assemble, usually requiring only basic soldering skills (for battery terminals) or no soldering at all (using spring contacts).
Use Cases & Applications
DIY Power Bank Cases are ideal for tech enthusiasts, students, travelers, and anyone who relies on portable power. They are perfect for charging smartphones, tablets, cameras, and other USB-powered devices while on the go. Imagine being on a long train journey and running out of battery – a DIY power bank solves this problem. They are also useful during power outages, providing a backup power source. Gamers can use them to extend their mobile gaming sessions. Photographers can keep their cameras charged during outdoor shoots. The flexibility to choose battery capacity allows users to tailor the power bank to their specific needs, whether it's a small, pocket-sized charger or a high-capacity power bank capable of multiple charges.
Buying Guide - How to Choose
When buying a DIY Power Bank Case, consider the number and size of battery cells you plan to use. 18650 and 21700 cells are common sizes. Check the case's compatibility with your chosen charging circuit and battery type. Ensure the case includes the necessary USB ports (USB-A, USB-C) and supports the charging protocols you require (e.g., Quick Charge). Look for cases with built-in protection circuits to safeguard your batteries and devices. Verify the case's dimensions to ensure it fits your desired capacity (mAh). Consider the quality of the materials (ABS plastic or aluminum alloy). Read reviews to assess build quality and ease of assembly. Finally, ensure the case comes with clear instructions or a readily available tutorial for assembly. Choosing a case with a built-in display or LED indicators is highly recommended for easy battery monitoring.
