Actually, the Protege
is a step up in voltage. Standard 510
batteries put of about 3.1v (I dont know why), and the Protege uses a standard 3.7v supply so you will notice an even bigger difference. I read somewhere a poster was checking the voltage output on different c-cig batts - they all came in at 3.7v except for the 510's. Even the ego's run at 3.1 volts. I had a hard time believing this so I did a vape test at home with a 510 atty on a 901 batt (w/adapter) - sure enough, the hits are stronger (and more vaper) with the 901 battery than a 510.
I also have a protege and love it. You made a good choice.
