Tips:
1.When working frequency is less than 500 MHZit get well gain flatness, can make it less than 1dB after careful adjustment. The lower frequency the higher gain consistency.
2.Amplifier working frequency of the lower limit is subject to input and output capacitor, the default value is 0.1 uF, working to 0.1 MHz. Increase the input and output capacitance appropriately, can extend the cut-off frequency, such as 10uF capacitance can work to 5KHz.
3.When the power supply voltage changes in 5-8 v, it can be used as a variable gain amplifier, gain increases with the increase of the power supply voltage, which suitable for radio frequency receive front-end circuit, using DA control power supply voltage, to control the gain of the amplifier, automatic gain control
4.When the power supply voltage in the 8-10 v, the low frequency end gain up to 30 db, at this time the amplifier has a low noise coefficient and good stability.
5.When the voltage is 12 v, reach maximum gain, the low frequency end gain of 32.5 dB.

EDIT:
I eventually ended up stripping an old 9v power supply that I found in the closet and switching it out for the battery connector I had before, and it's much less of a hassle that way. I would prefer not having to plug it into the wall, but it's better than switching batteries out ever other day.
So, I have raised my rating to 4 stars instead of my original 3 because it does exactly what I want it to do, and I knew before I bought it that these hassles were involved. So, if you like tinkering, or know your way around a simple wiring job, this thing is a good option.
5.5V is well within specification for this chip. I use this amp for filter sorting. My jig for filter measurement has 32dB of attenuation and this brings the signal back to 0dB
I added a shield to avoid pickup from outside.

Just one caveat: you'll need to BYOP (Bring Your Own Power) as its DC-blocking capacitors prevent it getting power from the coax. A nine-volt battery should do the trick however. Interestingly enough though, the amplifier ("N02" INA-02186 perhaps?) is designed to take bias-T power on its output pin (7V max), meaning that those adventurous enough to make some slight modifications might just be able to power the amplifier straight from the RTL-SDR!
As mentioned before, this amplifier performs quite well and can in fact attain its advertised +30dB gain. However, do note that, like any other LNA, it will amplify the noise floor somewhat as well.
In summary, this amplifier is ideal for anyone wanting an inexpensive upgrade for their RTL-SDR.
The main issue with this product is that it is NOT a 2000 MHz amplifier as RF amplifiers are specified. HP in its datasheet calls the INA-02186 a "3 db Bandwidth: DC to 0.8 GHz". As a narrow band amplifiers, as many reviewers seem to be intending, the amplifier will deliver some gain.

Absolute rubbish. Didn't work at all, if anything, it's a 30dB attenuator. Build quality looks shoddy, especially where the MMIC is soldered in place.
