Charging Speeds Explained

Charging Speeds Explained

Let’s face it, we could all do with a faster charge. But is it as easy as it sounds? Do we all just want to shove as much power into our phones in as little time as possible? Here’s a quick breakdown of how phone charging works, how speed is calculated, and what you can do to optimise your charging speeds.

So How Does Phone Charging Work?

Let’s start off with the basics of how a battery works. To do this properly we’ll need to throw around words like “electrons”, “electrolyte”, “cathode”, and “anode”. Electrons flow through a circuit, and through the battery (which completes the circuit), which contains electrolyte, a chemical liquid or dry powder. This process creates a chemical reaction on each electrode (at the ends of the battery), creating a flow of electrical energy. The electrons flow in 1 direction to generate an electrical current, which powers the device. In a rechargeable battery (like that in a phone), the process is reversed when recharged.

What is “Fast Charging”?

Fast-Charge, or Quick-Charge does exactly what it says on the tin. Charging speed is a product of voltage and amperage, the higher these are, the faster the charge. Keep in mind that not all phones are capable of handling the voltage and amperage required for a fast charge. Fast charging phones are built to withstand higher amps and volts, with some able to go from 0% to 50% in just 15 minutes.

Why do some phones charge faster than others?

When it comes to phone charging speeds, the cable and charging station will only provide as much power as the phone will allow, so think of phone charging as a “pull” of power by the phone, rather than a “push” from the charging device. Some phones have a greater battery capacity, so if you’ve put your iPhone in a Chargesafe for 30 minutes, you’ll go from zero to about 40%, but a phone with a greater capacity will show a lesser percentage, but will have received the same mAh.

To make sure you’re receiving the fastest possible charge for an iPhone, you’ll need an MFi cable. All of Chargebar’s cables are MFi certified, including our new Kevlar cables, which you’ll soon find in Chargebars everywhere.

How fast do Chargebars Charge?

Chargebars recharge phones at the fastest speed allowed by the devices’ manufacturers. Using a Riley on the wall of a bar, club, or late night venue for a few minutes is a great way to make your phone last the distance of a night out. We touch on a few common misconceptions in our “Biggest Phone Charging Myths” article, so check it out.
