You should be aware that wireless charging is less efficient (if more convenient) than wired charging. (I assume you know that the base has to be wired to the bike.) For desktop charging, the chargers come in different watt ratings - presumably a higher wattage base will charge your phone faster. This is up to a point since it also depends on the rate at which your phone will accept the power.
I'd suggest that you do a search on the internet and educate yourself about wireless charging options for your particular phone. The thickness and material of your phone case (aftermarket, if you use one) will also affect the charging rate. The case must be made of plastic (not usually a problem because most are) and you may not have a piece of metal such as a mounting lock on the back of the case.
