If you want to achieve optimal charging speeds and ensure the safety of your device, always use certified fast charging accessories compatible with your smartphone. In most cases, it is either USB Power Delivery or Qualcomm Quick Charge. When you opt for certified accessories, you make sure that your wireless charger meets all the safety and performance standards. If you go with a non-certified charging accessory, you risk overheating and shorting and may end up damaging your device as well as the wireless charger. It is normal for a charger to get warm as it powers up your smartphone. You don’t need to worry about it at all as long as it is made by a reputed company and is certified to be compatible with your device. A product is only certified after evaluating it for different safety measures. They must use a controller chip for regulating power flow to your phone’s battery. These chips help avoid any dangerous current spikes while charging. Besides, there are voltage and temperature controls in place as well to ensure that your wireless charger keeps charging your device safely. When you go looking for a fast charger or accessory to use with your smartphone, make sure that the product you choose is: • Made by a trusted manufacturer • Qualcomm Quick Charge or USB-PD certified • Available with all technical specifications and includes the warranty details to offer protection for your device against damages caused by that charging accessory
