I also love my Therion, it is 75 watts but with 2 batteries I get 2 full days of use from a single charge. Once again it is only 75 watts, but it is parallel not series. With two batteries I get solid performance all the way to the blinking battery icon. Wattage on many of these mods is a marketing gimmick. They are not pushing the actual wattage stated. Pick what you like.
I'd recommend the Lost Vape Therion 166 over the 75. Same form factor but a more efficient chip (better battery life) and 2 amp charging (if there's need to charge the batteries inside the mod). Also has reverse battery protection (not sure if the DNA75 chip has reverse battery protection, the DNA200 doesn't).
