Car chargers all suck

Why is it so hard to create a true 2.1A 5v car charger? Isn't it just a step down transformer 13.5 to 5v with all the amps the phone will take? My little charger barely keeps up with the phone galaxy S7. Will have to jump on the inverters 115VAC wall plug to charge this friggin phone.

You might just need a better charging plug, and using the factory phone charge cable (or HIGH QUALITY aftermarket) actually makes a big difference in charge times. I have the same phone and was a delivery driver for a while (and a Lyft driver before that), needed solid in-car phone charging for those jobs.
