Here Is a chart comparing charging speeds. At best the one you linked will charge at 7.5 W. If it’s not compatible with some special Qi thing that Apple does it will charge at 5 W.
The best budget charger is to use an iPad charger. Or look for a charger that can supply 12 W per port like this which can charge 2 devices quickly. You can use the cable in the box and it works fine. For cars anker also makes this which does the same.
