Review on WELAKER Lightning Transfer Charging Compatible by Omar Allen

9/20/21. This Welaker 2 port charger is actually an Intertek GS-50210A charger which I have been using for over a year since I bought the Ruideng voltage and current tester you see in the photo. I then went through all my chargers and cables to see which ones could handle 1.0 amp. Many chargers OR cables (you'll have to test each individually with known good ones) only handle 0.6A or 0.8A etc. so it will take longer to charge your device. Some will not work at all. The test device clearly shows all your good chargers and cables. Anyway, this Velaker combination works very well. See photo. Each USB port (even with a new cable) delivers the same output current of 1.0A or more. Since the charger model is the same one I've been using consistently for over a year, I don't expect any failures.
