Riva/Ego.. same or differant

[mom2-7girls]

I was wondering if these are the same thing or are they totally differant? What is the power and or vapor like, and can I incorprate my v4l (kr8) in with these with an adapter at all....?

Was thinking about going to Denton this weekend and want to know as much as I can before going.

The Riva is a clone of the Ego, the main difference being the battery (standard Ego = 650 mah, standard Riva = 750 mah). The ego does have a 900 mah batt available too.

The parts (atomizers, cartos, cones) are interchangeable between them. I think the main difference is the chargers.

IMHO, it's a nice step up from the regular models (I used 510s). Enhanced vapor production and definitely longer battery life. The cone helps to warm the vapor and that gives a different mouth feel compared to the same juice on a standard 510 batt.

There are also adapters for the kr808 to use either.

So I could still use my v4l stuff with the riva? I know my husband will still use the vfl. But I think I just need the next step up. I just dont want all my vfl stuff to go to waste. What parts are interchangeable and how would I adapt the 2 together...if I wanted to and what would be the reasons I would do that?

I think the main advantage to the Ego/Riva is battery life. The smaller devices may give you a couple hours of vaping before needing a charge (or batt swap). The desire for longer times between charging resulted in the bigger battery. But that also involved some sort of aesthetic consideration prompting the use of the cone (which in turn helped with minimizing leaking on the outside and kept the whole device cooler on the outside).

The main part that you would be interchanging is your atomizer/carts (which would need to screw onto an adapter). I expect many of the places that sell the Egos/Rivas also sell adapters.

As far as vapor and performance they are the same. The Riva has a button that seems to be preferred and a slightly higher rated mah stock battery, 750 vs 650. The Riva usually cost a little less. The Ego does have a higher rated batt available but it's not in the base kits and I've heard one is coming for the Riva but I haven't seen it yet. Both are compatible with 510 attys, others as well with adapters and they both use the same charger. I've had the Riva Kit for 5 weeks and I get several days in between charges on each batt. In fact I haven't had a dead batt yet I just charge cuz I think it's time. I must be a lightweight tho because others have reported 6-8 hours or more under heavy vaping.

As far as I know the Ego will need an adapter to use with KR8 stuff. Elegant (cigeasy) and defender (vapornine) do not need an adapter. They are made to be used with KR8s. I see Eastmall (maybe others too) has a Riva that is 510 and a Riva that is 901 which I'm pretty sure is compatible with KR8 cartos. (double check the 901-KR8 compatibility. Not sure on that one.)

This one is compatable with V4Life cartos. It's a Riva with KR808 (V4Life) threading.

The Riva uses the same capacity battery as the eGo, they just chose a different way to measure it..
Both have a voltage reduction circuit to drop the (nominal) 3.7 volts down to a constant 3.1 volts. Joye use 3.7 volts as the base to measure capacity, EM use 3.1...

That's the first explaination for the difference that makes sense to me!

May I ask where you got the info? (sorry, old habit, always go for source material)

 

[mom2-7girls]

Thanks for all the info, I am going to try a higher nic. first...and a manual batt. and then If I am still lacking then I will buy a RIVA for sure.... ( i just love the pink one...lol ) I will go to Denton and buy it so I can try it first and test out some flavors before I buy....

Nobodyatall,
Was by chance actually. Another member had pulled a Riva apart and the Wh (Watt hour) rating is printed on the battery - it was something like 207Wh if I remember correctly. Doing the sums.. 3.1 (volts) x 207 = 641 (pretty close to 650), 3.7 x 207 = 754 (near enough to 750). Interestingly that batt has "Joye" printed on it..
The other way I know they are similar in capacity is that I did a real world test by timing how long the batteries lasted under load.
I used a 3.3 ohm 5 watt resistor soldered to a 510 atty connector and timed how long each lasted. Suffice to say that I wont be doing that again in a hurry as both have a 15 second timer (ie: hold button until the light goes off, release, press again, repeat...) and each took over 40 mins to go flat!
The end result was that the eGo lasted about 40 seconds longer than the Riva - of course one has to take into consideration that I'm not a button pressing machine and some time differences are inevitable, but to get within less than a minute of run time to each other is a pretty fair indication they are much the same capacity.
Note that the run tests were done on a genuine eGo and an EM Riva - other copy/clones may have differing results (and/or claims) but my way of thinking is that it's not likely you can get a larger capacity battery using the same (Li-Ion) chemistry in that size casing.

Somebody posted that other day that the 510/eGo/Riva voltage output is actually 3.2 volts (using switch mode technology). As an oscilloscope was used to conduct that test, it would be a more accurate figure than my cheapy multimeter gave and I figured my calculations could be out...

Starting with the eGo batt at .65 Ah (650mAh): .65 X 3.7 (volts) = 2.4 (Wh). Doing the same for the Riva: .75 X 3.2 = 2.4
Can't get closer than that.

I tried the calculations on the the bigger 900mAh eGo and comparable 1100mAh Riva batts too. These didn't come out all that close (try them yourself), but not having either for a visual comparison I don't know if they are the same physical size. My guess is they are similar though and, as above, they are using the lower voltage to fudge the capacity figures.

It sure is 3.1v.

Here's more info, with pictures.

Basically what my meter shows too Katya, and is what my original calcs are based on.
Either way, my point was/is to show how figures can be manipulated to favour one brand over another.

Yup, yup.

Nominal voltage doesn't tell us much.

The small difference between the basic Riva and basic eGo is that the eGo is 650mAh, while the Riva--750 mAh, so it lasts a bit longer, maybe 1/2-3/4 hr. But then there are longer lasting versions of both on the market, like 900 and 1000 mAh eGo and 1300 mAh Riva, but they are also bigger.

 

[mom2-7girls]

I started out with the Riva, was happy with the round about 8 hrs....then I jumped on the LF deal on the eGo.... it lasts about a day and a half. I really like the eGo much better.

Did you read my original findings Katya? - the batts are as near enough to the same capacity. There is basically no difference, just that one manufacturer chooses to claim higher figures through using different starting parameters. I guess both could claim to be technically correct though.

I had to change my vaping procedure to get good results out of C-E2 XL cartos. They're somewhat sensitive to juice viscosity. All my juice is at least 50/50 blend. To provide a dwell time for the wick to recover I decided to use two different color PV's, and two carto's. For the past four days I've had a Riva, and an eGo, both connected to identical carto's, filled with same quantity and flavor juice. While at home I have one in my right hand and one in my left hand. I vape one until I detect a change in the vape, then switch to the other. Virtually no difference between the vape I'm getting out of both. There are tactile differences, the button, and the eGo button collar is recessed slightly. But, for my money they're essentially the same. I happen to prefer the Riva button, but that's getting pretty nit pickey. I have many more Riva's because I'm givin any my relatives that smoke one for Christmas. And it made more sense to choose the more economical brand when buying in quantity. JMHO

Cheers,

I just reread them. Sorry, I was concentrating on the voltage delivered and completely missed your point. Very interesting, indeed. I honestly believed that the EastMall somehow managed to squeeze additional 100 mAh into the Riva. I only own a 750 mAh Riva and a 900 mAh eGo. The eGo lasts longer than the Riva, but it is also physically larger; the eGo is about 1.5 cm longer. So it makes sense. Very clever. Thanks.

Riva's math makes a bit more sense, though, as the true working voltage is closer to 3.2v.
