The Riva may be higher voltage with no load, or fresh off the charger, but it's not regulated. So the Riva may only be "higher voltage" for a short period of time. Because as it loses it's charge, it also loses voltage. The eGo has a PWM circuit which keeps it's voltage steady until it's dead. That's the reason why the ego booster works only with joye eGos, and doesn't work on batts suchas the Riva. With the eGo have a constant voltage, it can boost that voltage and keep it steady up to 4.7v. With a Riva and it's constantly dropping voltage, it doesn't work.

I'm sure there's more to it than that, I'm not electrically smart enough to give you any details, that's just what I've read.

Hmm... Interesting.

I was under the (assumption?) that the Riva was also modulated, just to a higher average voltage. IDK about that booster thing... it's designed for one or the other, but not both since they differ. If the Riva is not modulated, then my post #11 is wrong too.

Of course, once they get to 100% duty cycle... they begin to drop off until cut-out threshold is reached.

Guess I'll have to dig in.......

my riva seemed to stay pretty consistant after the initial drop off, never really tested it but i never noticed any diminished performance untill the last few hits before the battery died, my old riva battery was before they were 3.7 and i noticed a huge difference in performance, even the end of the life of my 3.7 riva was about the same as my old riva battery, i just didnt want to deal with 3.2-3.4v's i prefer 3.7+ i need a strong kick in the throat n lotsa vapor

Quote from the thread: http://www.e-cigarette-forum.com/forum/happyvaper/202635-ego-booster-faq.html

"Does the Ego Booster work with the Riva or other 3.7 fat batt devices?

Sadly, no. We found that 3.7 volt fat batts just could not produce the current required by the Ego Booster. As mentioned previously, if you connect an Ego Booster to one of these devices you will not damage the Ego Booster, however you may damage the battery.

The Ego Booster uses the fact that genuine eGo batteries use what is called Pulse Width Modulation (PWM) to control the power going to the atomizer. If you use a device which does not use PWM, the battery must be capable of producing adequate current to power the Ego Booster. This is why we recommend high-current batteries for non-eGo devices."

Hope this helps

**edit** I don't know personally, but supposidly 1st gen Rivas had PWM chips, and would be compatible with the booster, so they should be constant voltage batts. It's the Riva SEs that aren't. FWIW.

I like my e-power, it's cheap and cheerful, but actually a sturdy enough battery mod. For the price it's hard to argue with IMO.

Still, like others here the paint coming off already after barely a week is a little alarming... Might go for a chrome one next time to avoid this. It looks sorta gold/brass underneath. When I've the time I'll look at chipping it all off and either re-painting with metal paints or maybe insulating tape or somethin similar.

My paint started chipping on my black e-power 18650, I also have a titanium e-power 14650 and had no problems with the finish. I came up with this easy inexpensive fix.

I bought some 3/4" heat shrink tubing black fits pretty close. Had to sand off all the tube paint, left it rough to grip the heat shrink tubing, used a hair dryer to shrink the tube. Looks great and now have a rubbery grip.

I like all my e-powers.

    Fresh bat , no load

    2 ohm Boge carto for load

    Looks like it is regulated, just not the same way an eGo is

    Testing that under load right off the charger won't show anything. You would need to test it under load fresh, after 30 min, after 1 hour, after 1 1/2 hours, etc, to see the difference that I'm referring to. You will probably see the voltage drop from 3.23 to 3 to 2.7, or something along those lines, after those testing phases. Testing it one time right off the charger isn't really going to tell you anything.

    I am having a weird thing happen with mine...it stops working so I unscrew the battery out & back in then it works for a few puffs then stops again...is that the switch...both bat & atty are fine....anyone know?

    I agree with the bad connection, but it may be the center pin on the carto isn't touching (this happens to me all the time). The threads on my unit weren't drilled very well and my connection is all screwed up now. It really is cheaply manufactured and I would not buy another one.

    I have both the E-power (18650) and NoEgo (14650) and I can tell you the NoEgo is better quality. I know it's made by the same manufacturer but the NoEgo is better built.

    I purchased a black 14650 E-Power for my mother (I was buying the silver NoEgo and she wanted one but doesn't come in black) and when it arrived, I inpected both 14560's for differences. My opinion is the NoEgo is better built.

    So in other words....Perhaps you should forget the E-power and look into the NoEgo. It's only $25 and you have the batteries already.

    Yes those things seem to help...Is this a reason to send it back or should I just put up with it?

    Do you want to put up with it?

    I ordered a new switch and another battery, but I'm not expecting much better. The only reason I didn't buy a new unit (different brand) is I'm waiting to see how Ikenvape's Ikon (ego-w) pans out and the new switch and battery for the e-Power were the cheapest option.
