Does Anker offer anything that would function as a potential product upgrade? I have an old model of the 4 port 36W charger and it is still working properly, but it does not have any of the features of the newer models, like Power IQ or any fast charging ports. It is standard and can output 2.1A in two ports and 1A in the other two ports.
I would like to upgrade to a new model, is there any way to do like a trade in for credit? The item still functions.
