Product Description

19V 4.74A 90W AC Power Adapter For SAMSUNG

ac adapter products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, LCD displays, LEDs Lamps, communication equipment, audio-visual products, security, computer cases, digital products and instruments

The benefits of ac dc adapte are many, but many people confuse the role of power adapters and batteries. In fact, the two are essentially different. The battery is used to reserve power, and the portable charger is a conversion system from the power supply to the device to the battery. If there is no power adapter, once the voltage is unstable, our computers, laptops, TVs, etc. will be burned. So, having a power adapter is a good protection for our household appliances, and also improves the safety performance of electrical appliances. In addition to improving the safety performance of electrical appliances, it is the protection of our own bodies. Imagine if our electrical appliances do not have a power adapter, once the current is too large and suddenly interrupted, it may cause electrical appliances to explode or spark, etc. The blasting or fire of the world is a great threat to our lives and health. It can be said that having a power adapter is equivalent to insuring our home appliances. Don't worry about those accidents anymore.
