Welcome @Askcoppola and I hope you enjoy your stay~!
To answer your question NO but there are advantages to High Powered MOD's and one being when I was using a 3 cell 200W box vaping at 10 Watts or so, boy did the batteries last a shit long time~!
Most dual battery mods have way more power than needed. For me it's more about run time between charges and not the higher wattage.
One of my fav's is a dual battery 75 watter.
If you like the smaller form factor of single battery mods [lower watts], you may still find yourself carrying around a charged battery.
I have the Aegis Legend and the Voopoo Vmate. Don't think you'll go wrong with either one. They're very different from each other, though, so might come down to a style choice for you.
