About 18 months ago I bought my first Syncwire products, some USB cables. They were so good that I started adding more Syncwire components, specifically power supplies and cables. From now on I only buy Syncwire components. I bought a 4-port adapter for use on airplanes to connect to the onboard power supply. It turns out to be too heavy to stay in the vertical outlet under the seats. If you look at the outlets they are grounded so I bought a Syncwire 2 grounding adapter and it works great. Remains in place even in gross turbulence and gives me strength across every ocean. Great products with excellent support.
