This question is one of the most common concerns of users, and to answer it, we need to look at various factors, including standards, quality of parts and technical specifications.
Charging standards and protocols
Table of Contents
Today, most smartphones and chargers use fast charging standards designed for cross-device compatibility. The most important global standards developed by standard organizations or large companies for widespread use are:
- USB Power Delivery, which is supported by many mobile phone manufacturers such as Apple, Samsung and Google.
- Quick Charge This technology was developed by Qualcomm and is used in many Android phones equipped with Snapdragon chips.
- Power Delivery PPS is a more advanced version of USB Power Delivery that allows more accurate voltage and current regulation.
These standards somehow guarantee a safe connection between the charger and the devices, so if a charger from another brand supports the standards compatible with your phone, you probably won’t have a problem with it.
We remind you that mobile phone manufacturers have their own charging standards. For example:
- Apple MagSafe for wireless charging of new iPhones
- Adaptive Fast Charging for Samsung phones
- Hypercharge for Xiaomi phones
- Warp Charge for OnePlus phones
- VOOC and SuperVOOC for Oppo and OnePlus phones
- TurboPower for Motorola phones
Global standards are compatible with a wide range of devices, while proprietary standards usually only work with products of the same brand.
Quality of parts
If the chargers of one brand are of lower quality than another brand, they may not provide a stable and suitable current for your phone (higher brand); For example, these chargers may be made of poor-quality electronic components that lead to output fluctuations, or they may not have the necessary protection features against overvoltage, overcurrent, or short circuit at all.
A low-quality charger with low-quality electronic components leads to output fluctuations
The importance of research and choosing a valid charger is also clear at this stage. Some chargers do not use proper insulation material and this is really dangerous. High-quality chargers, even if they are not of the manufacturer’s brand of your phone, usually have high-quality parts and necessary protections.
Technical specifications
Technical specifications such as voltage, current (amps) and output power of the charger also play an important role in its safety and efficiency. Despite the explanations in the previous sections, it is still recommended to use chargers whose technical specifications match or are higher than your phone; Thus, you minimize the challenges.
Physical damage to the charging port
Sometimes the damage caused by the charger to the phone is not due to electric current, but due to damage to the charging port.
For example, inserting the charger with too much pressure can bend or break the pins inside the port. Also, using the charger at an inappropriate angle will lead to the gradual erosion of the port. Of course, keep in mind that the accumulation of dirt in the charging port will destroy the optimality of the connection, and as a result, the battery will overheat.
