Welcome to
vaping (i.e., "smoking" e-cigs) and to ECF, Quinn!
Yes, one
can become "overwhelmed with a seemingly endless sea of information." But ECF (this electronic cigarette forum) and some suggestions I'll provide can help you with that.
The phrasing of your question indicates to me that some guided education about "
vaping" could be very helpful for you. I urge you to read or, at least, peruse the WWV Illustrated Guide linked in my signature. In a
sense, it is
ECF: The Readers Digest Version.

You'll gain a much greater understanding about what this stuff is all about. And, since it is "illustrated" with photos and videos, you can actually see various types of e-cigs and how they are used.
What I provide here skims the surface to address the specific question you asked.
Like a personal computer, an "electronic cigarette" is both hardware and software. The
hardware is the device
– that thing you hold in your hand and suck on, and which vaporizes the
software, i.e., the e-liquid you put into it.
Unlike a tobacco cigarette (what we refer to as an "analog") such as your Camel Straights, the hardware and software do not come prepackaged. It's as if you rolled your own cigarettes using tobacco and papers.
So there are really two parts to your question:
- What looks and feels most like a very short cigarette such as Camel Straights?
- What tastes most like a Camel Straight cigarette?
The answer to the first question is
hardware-related, i.e., what
model of e-cigarette is the smallest (while still performing well)? The answer to the second is
software-related, i.e., what
e-liquid tastes most like Camel Straights?
The Hardware
If you want your e-cig to be as small as possible, you will need to purchase a "super-mini." The various models (and their sizes) are described in
Part 4 of that guide. Some of these are the same size as a regular king-sized cigarette.
None are quite as small as an unfiltered Camel.
Quite frankly, there is a considerable trade-off required by a super-mini. On average, the battery, atomizer, and cartridge (the components of an e-cig, described in
Part 2) are just not big enough to deliver the same throat hit, vapor, and flavor (also described in Part 2) as a "mini" or "penstyle," and the frequency of battery recharging leaves a lot to be desired.
After Part 4 of that guide was written, at least two other super-mini models have been introduced:
- The M702 (also marketed as the Revolver Elite) which comes with its own PCC (personal charging case) so that you can recharge those rapidly tiring batteries while you are out and about. It is described in Part 6.
- A short battery for the KR808D-1 two-component e-cig (battery + integrated cartridge and atomizer), which puts it into super-mini range.
The Software
I'm going to leave this as "an exercise for the student."

That is, e-liquid is described in detail in
Part 3 of that Guide I keep referring you to.
You'll learn that no e-liquid tastes exactly like an analog cigarette. [After you have been vaping for awhile, you'll find that you wouldn't want it to.] An obvious flavor for you to try is "Camel" (often deliberately mispelled to avoid trademark infringement). Many suppliers carry it and it is even available in
KR808D-1 cartomizers (look for "Camule"). However, there are a great many tobacco flavors, some of which you probably will enjoy. That is where samplers can be helpful. And, yes, you can find sources for samplers in that Guide, this time in the second half of
Part 5.
Enjoy your investigation of this exciting new world, Quinn!
