Wireless Charging Head/MAG Charging Head (Car/Desk) FAQ

This is a collection of commonly asked questions about the operation of the Quad Lock Wireless Charging Head

If you're looking for installation instructions, scroll to the bottom of this article for links to those. 

What are the power adaptor requirements of the Quad Lock® wireless charger?

  • To achieve standard charging output of 5W - This requires an adaptor with a minimum output of 5 Volt/2 Amp*
  • Fast charging output 7.5W & 10W - Requires an adaptor with a minimum output of 9 Volt/1.67 Amp

*Most computer/laptop USB ports output 5V/0.5-0.9A so are not recommended for powering the Quad Lock® Wireless Charger. The minimum power requirements are 5V/2A but we recommend the use of a QC 2.0/3.0/4.0 (9V/1.67A) power supply as it will provide sufficient voltage and current required for fast charging (9V/1.67A)

The Quad Lock® dual USB Car charger is a good option for in car use:

What is the difference between standard and fast wireless charging?

Standard wireless charging is 5W. Fast Wireless charging is charging above 5W up to a maximum of 15W.
The Quad Lock Wireless charger only supports 5-10W wireless charging output, depending on your phone's wireless charging capabilities*.   

  • 5W (baseline power profile which works with all wireless charging phones)
  • 7.5W (iPhone)
  • 10W (Samsung Galaxy S7 up to S10/Note10)
  • 15W (Google Pixel and Huawei phones)

*Some manufacturers have implemented their own Proprietary Extended Power Profile (PEPP) for their devices. This means unless you are using a charger specifically designed to support that PEPP, you are limited to the Base Power Profile of 5W wireless charging.

Wireless charging Speeds seem slower than charging via a cable?

Yes, unfortunately, even fast wireless charging is slower than an equivalent wired charger of the same wattage. This is because wireless charging is only 70-80% efficient meaning 20-30% of the power is lost during the wireless transmission process. We have an in-depth article around expected wireless charging speeds over here: https://support.quadlockcase.com/hc/en-us/articles/360001578175

My wireless charging head doesn't automatically start when I start my car.

In some cases the wireless charging head may not activate when your ignition is started when plugged into a 3rd party USB charger. This may be resolved by using our 12 Volt Charger or simply reconnecting your USB plug to your adaptor.

My phone has stopped charging on my wireless charger when it was previously working.

This is usually down to a recent software update and is most commonly resolved by turning your phone off and on again. If you're still continuing to have charging issues please feel free to reach out to our support team.

My phone gets hot when using the wireless charger? 

Wireless charging is only 70-80% efficient so the additional 20-30% of energy is converted into heat. In normal conditions this is not usually a problem, however using the wireless charger in your car in direct sunlight can compound the temperature and cause some phones to overheat.

Apple's guide to temperature regulation recommends keeping your phone out of direct sunlight or operating in a hot vehicle.

If this happens remove your phone from the charger and allow it to cool before further charging. If possible, positioning the phone/charger near an A/C vent can help keep the phone and charger cool.

Why don't you recommend the use of the Universal Adaptor with the Quad Lock® Wireless Charger?

The thickness from the Universal adaptor plus the phone case can create a too large distance between the wireless charging coils for the charger to work efficiently. Additionally we cannot guarantee the alignment of the adaptor on the case/phone which can impact the charging performance.
