Located in Shenzhen’s Bao'an District, Merryking Electronics has been manufacturing high-end power adapters and chargers since 2005. We design and produce our own power adapters and power supply units, and have certifications for our adapters for 1-420 Watts. Our 20 Watts USBC Power Adapter is one of our finest adapters. All of our adapters undergo performance and reliability testing, including aging tests, and we do this despite the fact that our adapters offer optimum performance. As a result, we are able to offer a brand name reputation to our manufacturers, and that is the reason Honeywell and Calix have branded us as their manufacturers and we have the complete right to brand them as our manufacturers. Since we are 100% our own manufacturers, we have the complete right to state that we have low pricing. Our design and produced power solutions, for this reason, have a 3-year warranty which designates our power solutions as a world preferred solution.
