Yeah, that's pretty much exactly right. And that's not really because of the limitations of the Booster, its more because of the limitations of the battery. The Booster can handle up to 3A, which is more than an eGo Battery can supply.
Right now I tried to vape on minimum and maximum voltage. My own sense is the same: on maximum voltage power is less than on minimum, i.e. voltage is less. My atomizer is not too LR, almost 2 ohms...
Just for information: I basically understand electricity and electronics. I solder my own boards, read datasheets etc.

Slimest,
If I understand your question correctly (and I apologize if I don't) the reason there is a difference between load and no-load on the eGo battery is because the battery pulses as a way of limiting the current, and it does this in response to the load. If there is no load on the battery, there is no pulsing. As the load gets higher, the duty cycle of the pulse gets shorter (again as a way of limiting the current and protecting the battery).
The eGo Booster just superimposes its output voltage on top of the battery's output, so if the battery is producing 3.7 volts (for instance) at a 50% duty cycle, then the output of the Booster set at 4.7V will be 4.7V at the same duty cycle.
If you are worried about your Booster not functioning properly (i.e. to test it), then try the unit on an SR atty. If all is working correctly then you should see the nice change in vapor production that everyone sees. If you measure the voltage out of the Booster under load you will still get weird values (its impossible to predict what the numbers will be, since it depends on what duty cycle the battery is operating at, whether your multimeter is true RMS or not, and a bunch of other factors), but you should definitely notice the change in vapor production as you vary the dial.
Also, you should try different atties. You may find that one 1.9 ohm atty doesn't work the same as another 1.9 ohm atty. There are often manufacturing differences that can affect the performance.
The same goes for using different batteries of the same type.
MasterofChaos, my question was: why my eGo Battery can supply adequate power on load with atomizer with resistance 1.9 ohms and even lower (tried on 1.5 ohms), but if I use the booster, I just can not achieve ANY effect using absolutely standard resistance - 1.9 ohms. If this resistance is inacceptable for the device, the seller should explain this.
Shure I understand, that I could be not lucky and got bad device. Sometimes happens...
P.S. I tried 3 batteries, all genuine Joye. 900 ma-h.

When I got the Ego booster I was aware of its limitations with LR atos. I am satisfied with the way it works with SR atos. I have some G4, 2.6 Ohms on it on a 900Mah Ego bat, and it works just fine. For high amp aplications you just need another mod.
Then, at a 18650 NoEgo it works well, but doesn,t give the bite with 1.6 Ohm DC´s the madvapes VV box gives. To be honest, that box is the best with these DC´s.
On a 18650 NoEgo the booster with atys rating at 2 Ohm or more its perfect.

I am service representative on electronic company. If this was my own case, I decided that there is a bad contact inside... So we have voltage drop. Tried to find out if the device warms up, no joy, because everything warms...
Slimest,
Actually there is a fair bit of difference between using a battery with an eGo Booster attached driving a specific load and just the battery itself driving a specific load. The eGo booster will maintain the output voltage no matter what, even as the current draw goes up. A bare battery, on the other hand, will let its output voltage drop as the current increases. As the battery voltage drops, the current into the atty goes down, and eventually the battery reaches a point where it can maintain the lower current into the atty without dropping the voltage any further.
For instance, the output of an unregulated 3.7 volt battery driving an LR load will drop to, say, 3.2 volts or even lower to drive the load.
The eGo Booster, on the other hand, if set to 3.7 volts keeps its output at 3.7 volts. As the battery voltage drops below 3.7 volts, the switching regulator in the eGo Booster will draw more current to maintain the output voltage at 3.7 volts. This causes the battery voltage to drop even further, which causes the booster to draw more current, etc. Thus as the battery voltage goes down the system with the eGo Booster draws MORE current not less like the bare battery system.
This is why the Booster doesn't work on unregulated batteries or eGo clones like the Riva.
If you want to discuss this further, please PM me and I'm sure we can figure out what's going on. As you said, a 1.9 ohm atty shouldn't really cause any problems, so I'm not sure why your setup isn't working as it should.

My hands up 
I don't know how to explain: on standard eGo battery and load 1.9 ohms voltage even does not try to increase on booster and even drops. This battery (from my experience) has enough reserve in current to supply at least minimal voltage adjustment. But in my case voltage progressively drops.
Seems that my english so poor...

ummmm..medium resistance? lol my orders don't vary much, so i don't know what ohms all the gear comes in
Today I tried to measure output voltages with atomizer 2.4 ohm. Got these values:
Max - 4.20
Middle - 3.71
Min - 3.19
Used the same batteries - Joye eGo 900 ma-h, fully charged. I think, these results are acceptable enough for practical use. Declared parameters are slightly different because of nature of pulsed voltage, if I used constant voltage, output would be higher.
My conclusion: if we use this booster with usual eGo batteries, we should not use atomizers with resistance lower than 2 ohm, otherwise this device inefficient at all. I did not try the booster with more powerful power supply, but guess that with it the booster can effectively supply more power.
P.S. Maybe in my case batteries are guilty, but I tried 3, purchased in different times, and all of them are genuine Joye, I am shure.

Which is exactly what the manufacturer states in this faq and on their website
It's been double checked now by a third party, so I guess that's a good thing?Well, the booster should work (I've tested, it works fine) with a 650 mah ego battery. From my basic understanding of electricity, the mahs of a battery indicate the capacity of a battery or, more basically, the length of time you'll get before you charge. A 1300 mah battery will last twice as long as a 650, and a 900 will be somewhere inbetween. When upping the voltage with the booster, the only thing the mah affects is again, the capacity of the battery. So for example if you normally get 8 hours use out of a 650 mah, with the ego booster, you'll only get 6 hours. If you get 12 hours out of a 900 mah battery, you'll only get 9 hours, etc etc.
