I'm very pleased with the Rush charger. I've been using it to charge multiple devices. Very slick device.
I tried the new RushCharge on my IPhone Pro14 and it would not charge the phone. By trying other IPhones I realized that the protective cover on my IPhone prevented proper contact. So I recommend you indicate to customers to strip all covers from your phone to make it makes contact. I bought a thinner protective cover that allows proper contact and RushCharge works as advertised.
My order from Rush charge was delivered directly to my address as expected.
