1. 36W GaN ultrathin charger manufacturers recommend checking the input voltage

　　For example, 100~220v/50~60Hz is a broadband input voltage. The input voltage of domestic and foreign charging heads is different. For example, foreign charging heads only have 110v voltage. If they are used in China, the consequences can be mild or serious.

　　2. Look at the output voltage

　　36W GaN ultrathin charger manufacturers suggest that you can choose an output voltage of about 4.9~5.1v, and the higher the output current, the better. But the allowable output current≠real output current.

　　3. Whether it has passed the national CCC certification

　　With the adapter approved by the state, the electrical safety and electromagnetic compatibility performance have reached the national safety requirements, which also ensures the safety of users.

　　4. Whether there is a "back" sign

　　36W GaN ultrathin charger manufacturers are next to the 3C certification mark, it would be better if there is a "back" type 0 mark. This mark represents that the charger has double-layer insulation protection. When one of the insulation methods fails, the second will be connected, also for safety reasons.

　　5. Whether the shell is flame retardant

　　36W GaN ultrathin charger manufacturers believe that the charging head is generally made of recycled plastic and virgin plastic. Recycled plastic is cheaper, and it is not flame-retardant, nor is it a hard material. Virgin plastic, on the other hand, is a high-quality material that is hard and flame-retardant.
