Charging speed can vary depending on several factors. If your device is not charging as quickly as expected, this is usually related to power requirements and equipment compatibility rather than a fault with the cable.

This guide explains what affects charging performance and how to achieve the fastest possible speeds.

 

What determines charging speed?

Charging speed depends on the combination of:

  • the cable’s power rating

  • your wall charger output

  • your device’s power requirements

  • the charging protocol supported (e.g. USB-C Power Delivery)

  • battery protection and temperature controls

All components must support fast charging for maximum speed.

 

Cable power rating matters

Magnetic cable ranges support different maximum power levels.

Higher-power cables are required for charging larger devices such as laptops.

If a lower-power cable is used with a high-power device, charging may be slower or the device may maintain its battery level rather than increase.

👉 See the compatibility guide to identify your cable range.

 

Your wall charger is equally important

The cable cannot deliver more power than the charger provides.

For best performance:

  • use a high-output USB-C charger

  • ensure the charger supports fast-charging standards

  • use a quality cable designed for high power delivery

 

Devices only draw the power they need

Your device controls how much power it accepts.

For example:

  • phones draw less power than laptops

  • tablets draw moderate power

  • wireless accessories draw minimal power

Using a higher-power cable will not damage your device.

 

Why fast charging may not activate

Fast charging may not activate if:

  • the charger output is too low

  • the device does not support fast charging

  • a lower-power cable range is used

  • the battery is near full capacity

  • the device temperature is elevated

This behaviour is normal and protects battery health.

 

Charging slows near full battery

Many devices reduce charging speed once the battery reaches approximately 80–90%.

This helps:

  • reduce heat

  • protect long-term battery health

  • improve battery lifespan

Your cable is still working correctly.

 

Tips to achieve the fastest charging speeds

  • use a high-output wall charger

  • use the correct cable range for your device

  • ensure connectors are clean and fully aligned

  • avoid heavy device use while charging

  • keep devices cool during charging

 

Good to know

  • charging speed varies by device and charger

  • higher-power cables support faster charging for larger devices

  • wireless accessories charge at lower power levels

  • slower charging near full battery is normal
