Why does my phone get 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 issue and cause some phones to overheat.

Apple's guide to temperature regulation, which has some crossover with other phone brands, 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 continuing to charge. If possible, positioning the phone/charger near an A/C vent can help keep the phone and charger cool.

We have further information about expected wireless charging speeds and the effects of heat over here.

What are the power adaptor requirements of the Quad Lock Wireless Charging Heads?

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 and as such are not recommended for powering the Quad Lock® Wireless Charger. The minimum power requirements are 5V/2A but we recommend the use of a Quick Charge 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).

What is the difference between standard and Fast Wireless charging?

Standard wireless charging is 5W whereas Fast Wireless charging is charging above 5W up to a maximum of 15W. The Quad Lock Wireless charger supports a 5-10W wireless charging output which is dependent 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 PEPP, you are limited to the Base Power Profile of 5W wireless charging.

Wireless charging Speeds seem slower than charging via a cable, why is that?

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 support article around expected wireless charging speeds which can be found here.

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 too larger 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.

Why doesn't my Wireless Charging Head automatically start when I turn my car on?

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 Dual USB 12V Charger or simply reconnecting your USB plug to your adaptor.

What's the difference between Weatherproof Wireless Charging head and the standard Wireless Charging Head?

There are several differences between bother of these charing heads. The weatherproof version of the charger is designed for outdoor use on motorcycles as it needs to withstand vibration, impacts, UV, and be resistant to chemicals (petrol, oil etc) which requires more durable materials and a very robust design.

Our Weatherproof Wireless Charger provides the following features:

  • Patented Dual Stage lock for secure mounting
  • Anodised Aluminium rear housing to keep it cool while charging.
  • IP66 water resistance enclosure so you can ride in the rain and wash your bike
  • Thermal protection to prevent overheating.

  • The standard Wireless Charging Head is for indoor use such as in your car or desk.

    Will the Weatherproof Wireless Charger drain my battery while I'm parked?

    The Motorcycle Wireless Charger may draw a small amount of power from your battery when not in use depending on how you have wired it up.

    If you wire the charger via a factory USB port or wire it into a switched supply (light circuit or accessories), it will switch off when the circuit switches off and will not draw power.

    If you wire it via a SAE connector directly into your battery, the device will draw a very slight current when not in use (unless using our 12V to USB Smart Adaptor in Auto mode of course, in which case the device will shut off when the battery drops to 12.5V)

    If the power button on the wireless head is switched on, it will draw 12mA. If the power button on the wireless head is switched off, it will draw 6mA

    An average motorcycle battery this will take about 1 month to drain at 12mA or 2 months at 6mA. We recommend disconnecting the charger from the battery if your bike is parked and not started for prolonged periods.

    If your phone is left attached to the charging head it will continue to draw current and charge, even if your bike’s ignition is turned off if wired directly to the battery.

    What kind of charge rates should I expect from a wireless charger?

    There are many variables which can impact the charge rate of your phone such as battery percentage, applications, having the screen on/off and ambient temperature all have an impact.

    Different phone manufacturers also implement different approaches to manage the charge rate in the aim to protect the phone's battery.

    Best Case Scenario

  • Almost flat battery (Less than 5%)
  • No Apps running, especially ones which use the GPS
  • Screen off
  • Low ambient temperature (~20 degrees C) in shade

    We've seen charge rates of 1% increase every 2 minutes or a 30% increase in battery charge every hour.

    Worst Case Scenario

  • The battery is almost full (Above 80%)
  • Running lots of Apps, one using GPS (maps etc)
  • Screen on
  • Hot day (30 degrees C) and in direct sunlight
  • You may only see a 1% charge increase every 10 mins. 6% battery level increase in 1 hour.
