Rock explains the differences between GaN, PD and traditional charging for mobile tech

A new tech has emerged for charging your mobile devices called GaN (Gallium Nitride), but what is this GaN and do I need to change my traditional mobile phone charger?


GaN Charging Explained


1. Power Packed in a Compact Size

One of the best things about GaN chargers is their ability to deliver higher power output without the bulk. Traditional chargers need larger components to provide more power, but GaN chargers can do it all in a smaller, lighter package. Imagine having a charger that’s as powerful as your current one but fits easily in your pocket.


2. Super-Efficient Charging

GaN chargers are more efficient than standard chargers. Thanks to their lower resistance and better energy conversion, less energy is wasted during the charging process. This means faster charging times for your devices and savings on your electricity bill.


3. Less Heat, More Safety

Ever noticed how warm your charger can get? GaN chargers generate much less heat compared to traditional chargers. This not only makes them safer to use but also extends their lifespan. GaN chargers are designed to dissipate heat efficiently, so you don’t have to worry about overheating or damaging your devices.


4. Eco-Friendly Charging

In today’s world, being environmentally conscious is more important than ever. GaN chargers consume less energy due to their high efficiency, reducing their carbon footprint. By opting for a GaN charger, you’re contributing to a greener future and helping to minimise electronic waste.


Advantages Of GaN Chargers

Now that we know the benefits of GaN chargers, let’s compare them to the traditional ones we've used for years. While traditional chargers have been reliable, GaN chargers offer some advantages but the technology will come at an extra cost:

  • Size and Portability: GaN chargers are smaller and lighter, making them perfect for travel and everyday use.

  • Efficiency: They charge devices faster and waste less energy.

  • Heat Management: Less heat generation means safer and longer-lasting chargers.

  • Future-Ready: GaN technology is at the forefront of innovations, including wireless charging.


GaN vs. PD vs. Traditional Chargers: What’s the Difference?

GaN stands for Gallium Nitride, a super-efficient material used to power electronics. GaN chargers use this material to boost efficiency while reducing the size and weight of the charger. On the flip side, PD stands for Power Delivery, a technology that lets devices charge at higher wattages for speedier charging times. Are you confused which is best to purchase for a speedier charger over a traditional charger?


Speeds:

GaN Chargers:

  • Super Speeds: GaN chargers are famed for their super-fast charging, up to 4 times faster than traditional chargers.

  • Power Density: Their secret is they have a higher power density, which means they can pump more power into your device in less time.

PD Chargers:

  • Quick and Steady: PD chargers leverage Power Delivery tech to charge up to 3 times faster than traditional chargers.

  • Not Quite GaN: While speedy, they aren’t quite as fast as GaN chargers.

Traditional Chargers:

Steady: Available in a range of speeds suitable for charging your mobiles and tablets, the higher the amperage/wattage the quicker the charge so choose a charger that is suitable. If charging multiple devices choose a charger with a higher output.

Sizing:

GaN Chargers:

  • Pocket-Sized Power: Thanks to the lightweight and efficient GaN material, these chargers are small and portable.

  • Travel-Friendly: Perfect for throwing in your bag without adding bulk.

PD Chargers:

  • Still Compact: PD chargers are pretty portable too, though slightly larger and heavier than GaN chargers.

  • Lightweight, But Not Lightest: While compact, they can’t quite match the featherweight nature of GaN chargers.

Traditional Chargers:

  • Small Enough: Traditional chargers are still very portable and sizes are the same as PD chargers.


Compatibility

GaN, PD and traditional chargers are versatile and work with a variety of devices like smartphones, laptops, tablets, and more; the difference between all these chargers is the spec, speed, efficiency and size.


Rock's Verdict

When it comes to choosing between GaN, PD and traditional chargers, it really boils down to what you value more? Do you want the absolute fastest charging and lightest weight with GaN, the solid performance and versatility of PD, or do you prefer a reliable traditional charger that charges your devices safely and efficiently but is not so compact and is affordable? Either way with GaN or PD charging you’re looking at scope of a lot faster & more efficient charging but with an increase in price.
