In today’s digital world, running out of phone battery can feel more stressful than losing your keys. But did you know you can make a functional portable charger in just five minutes using items you probably already have at home?
In this article, we’ll show you how to build one with a clever, low-cost method—perfect for emergencies.
What Is a DIY Portable Charger?
A DIY portable charger is an improvised device that lets you charge your phone when you don’t have access to a power outlet. While it won’t replace a commercial power bank, it can save the day in situations like travel, power outages, or outdoor adventures.
Materials You’ll Need
- An old USB cable (ideally the type that fits your phone)
- A battery holder (for 2 to 4 AA batteries)
- 2 to 4 fresh AA batteries
- Electrical or duct tape
- A female USB connector (if your battery holder doesn’t already have one)
Step-by-Step Instructions
1. Cut the USB cable
Use scissors or a utility knife to cut your old USB cable. Keep the end with the USB plug—you’ll connect this to your phone.
2. Strip the wires
Inside the cable, you’ll find several wires. The ones you need are the red wire (positive) and the black wire (negative), which carry the current.
