How does fast charging work and what do you need for it?

You know that feeling when you need to quickly recharge your phone before you leave and a regular charger only delivers a few percent in ten minutes? That's where fast charging comes in - the technology that gives you peace of mind (and a battery over 50%) in minutes. We explain how it works, what you need to use it, and how Cubenest products support fast charging.

What is fast charging?

Fast charging means that the device is charged at a higher wattage (W) than the standard 5 watts.  This is achieved by a combination of higher voltage and/or current.

For example:

• Standard charger: 5 V / 1 A = 5 W
• Fast charger: 9 V / 2 A = 18 W
• Some models reach up to 30-100 W or more (e.g. for laptops)

What do you need for fast charging?

1. A device that supports fast charging

• iPhone 8 and newer: support 18-27 W via USB-C/PD
• New Android phones: often 25 W, 33 W, even 67+ W

• Tablets and laptops: require even higher power (30-100 W)

2. A charger with sufficient power

• For example, Cubenest GaN chargers with outputs of 30 W, 65 W or more.
• GaN technology (Gallium Nitride) allows smaller size and higher efficiency without overheating
• Our most powerful charger Gan S6D0 with 240 W can handle fast charging of up to 6 devices 👉 link here

Tip: even if your phone has a 20W limit, a 65W charger will still help - it will provide exactly as much as your phone can safely take.

3. A cable that can handle more power

Not every cable is the same. Fast charging requires a quality USB-C cable, preferably:

• Certified for Power Delivery (PD)
• Supporting a minimum of 60W/3A
• Cubenest products often include quality cables already in the package - or they can be purchased separately

Fast charging and wireless technology

• MagSafe charging for iPhones: up to 15W (when using an original or certified charger)
• Qi wireless charging: typically 5 W, some power banks up to 15 W
• Qi2 - a new wireless fast charging standard with magnetic alignment and higher efficiency
• At cubenest, we offer chargers with both Qi and Qi2 support, so you're ready for the future of wireless fast charging.

Summary: What do you need for fast charging?

• Phone/tablet - Support for fast charging (PD, QC...)
• Charger - Power of at least 18-30 W, ideally GaN
• Cable - USB-C with 60W support or more
• Wireless - Qi2 or MagSafe 15 W compatibility
