Wireless charging - is it safe?

How Safe Are Wireless Chargers?

Wireless chargers are very safe! In fact, you can be in close proximity to a wireless charger at any time. This means you can leave it on your desk at work, or let it charge your device overnight on your nightstand. Your wireless charger emits a harmless signal searching for a receiver coil while its not in use. But because the coil inside your smartphone requires contact with the charging base, signal does not disperse into the surrounding air. Anytime your phone makes contact with the charging base, the signal focuses on its receiver and begins to charge. The entire process emits less radiation than that of a phone connected to a mobile network.


Does the Charger Get Hot?

Both wired and wireless chargers release heat energy during a charge. Chargers that have been extensively tested regarding their efficiency tend to minimize the amount of heat energy they waste. Therefore, its worth choosing a well-known brand to ensure the charger’s efficiency. STARQ chargers contain further safety measures pre-built within their circuitry. Advanced chipsets in each charger automatically shut down if any excessive heat is detected - protecting both you, and your device.

We designed chargeONE with heat in mind. chargeONE comes with a fabric that keeps your phone cool (both in terms of temperature and aesthetics) while charging.


Should I Look for a Specific Certification?

Yes! Always look for Qi certified wireless charging pads. Doing so ensures compatibility with your smartphone and any other devices.

If your charger is accredited to have been specifically developed for your smartphone, this guarantees a higher likelihood that it will work better with your device. For you, this greatly reduces the chance that your device’s features and capabilities will be compromised. Compatibility icons on your smartphone model make this easy to find out.

Check for international safety standards that guarantee your charger adheres to legal safety guidelines. Each one assures safe emission levels and manufacturing with the use of non-hazardous materials. The laws are different for each country, but key standards to look for include:

  • FCC
  • CE
  • And RoHS 

Can My Wireless Charger Get Wet?

Many smartphones promise water-resistance or waterproof capabilities. However, most wireless chargers are not. Just like wired electric devices, liquid can be dangerous to the health of your wireless charger. Keep your wireless charger dry, and make certain it is never wet before you charge.

 
Is it Possible to Overcharge my Smartphone?

Duration
The majority of wireless charging pads will trickle charge phones to keep them fully charged at all times. Trickle charging is a technique that applies a small amount of current to a device’s battery if it dips below 100% while charging. This method is safe, and you won’t have any issues with charging your phone for an extended period of time.

Voltage
Our chargers are equipped with intelligent microchips, known as smartchips. Smartchips deliver the precise amount of power that your smartphone requires. The microchips are also capable of delivering greater power, but will only do so for devices with a higher charging threshold.

Surges
The charging base is connected to a wall outlet which may be affected by power surges, such as lighting strikes. You will be happy to hear that its not possible for your wireless charger to pass an increase in voltage to your smartphone. This makes wireless charging safer than using a wired charger connected to an outlet.

 

What if I Place an Object on my Wireless Charger?

A charger of poor quality may be unable to detect a foreign object on the pad under your device. The lack of detectability allows the charging pad to continue emitting power, causing damage to your smartphone and potentially melting the object onto the pad. That’s why its important to search for a charger with built-in foreign object detection like our chargeONE is equipped with. A foreign object detector stops charging immediately, and alerts you when anything other than a compatible device makes contact with the charger. This functionality helps prevent any unsafe charging.
