The Zendure SuperPort and SuperTank are positively talked about on hundreds of blogs throughout the internet. I ordered (I paid for it) 2 SuperPort USBC chargers and a SuperTank 27,000 mAh battery. Both devices have the same design defect. When you have something plugged into the 100-watt port and then plug/unplug another device in the 60-watt port, it resets the 100-watt port every time.
My first 2 SuperPorts were sent back to Zendure for engineering review and the 2 replacements also exhibit the same behaviour. I just tested the SuperTank and can confirm it does the exact same thing.
I have been a Zendure fan and own all of their previous devices. None of them have this same defect. At this point I would recommend you look at other brands for your battery and wall charging needs. I have gone back to my Omnicharge Pro USBC for my battery and will carry an Elecjet and RavPower GAN USBC wall charger.
