Portable Chargers 101: Your Ultimate Guide

Picture this: You're on a road trip, your phone's battery is at 5%, and you need directions. Panic? Not if you have a portable charger! These compact lifesavers ensure that your devices stay powered up no matter where you are. Whether you’re on the go, interrupted by weather-related power outages, or experiencing an emergency, a portable charger is your best friend. This ultimate guide will walk you through everything you need to know about portable chargers – from how they work to what to look for in one!

What is a Portable Charger?

A portable charger is a compact device that stores electrical energy and allows you to charge your electronic devices on the go. These handy gadgets have become essential for modern life, ensuring that your smartphone never runs out of juice, no matter where you are.

How Do Portable Chargers Work?

Portable chargers store energy in their internal battery, which you can transfer to your device when needed. When your phone needs charging, you connect it to the portable charger. The stored energy is then transferred from the portable charger to your device, replenishing its battery.

Types of Portable Chargers

There are two primary types of portable chargers: rechargeable and pre-charged. 

Rechargeable Portable Chargers

Rechargeable portable chargers can vary in size and capacity and require users to pre-charge the battery before they can begin supplying power to their phones. For many of these types of chargers, a special charging cable is needed; it can take several hours of charging before a rechargeable portable battery is ready for use! Also, it can be easy to lose track of whether the charger was recharged before you take it on the go. With repeated use, rechargeable batteries lose their ability to hold a charge which means they can become unreliable when you need them the most.

Pre-charged Portable Chargers

With pre-charged portable chargers, there’s no need to charge the battery before use! That means you won’t have to deal with the hassle of plugging in the charger with a special cable just to get it ready to power up your phone. ChargeTab is a pre-charged emergency mobile device charger that comes in a sealed, eco-friendly, biodegradable paper shell, ensuring it’s ready to go the moment you need it. Simply break it out, plug its small, permanently attached cord into your phone, and start charging!
