The SD Keyring is a stealth PV mod created by Trog, who brought us the original Screwdriver PV mod. At only 44mm without cartomizer, this is a very small device, and is easily concealable for “undercover vaping”, and extremely portable as a backup.
The unit is rated at 300mAh, and comes complete with a USB charger, and two prefilled cartomizers.
Only slightly larger than a cartomizer, and smaller than a roll of candy, the SD is tiny.
Okay, we can see this PV is portable, but how does it vape?
First things first…the packaged prefilled cartomizers aren’t the best tasting, but are easily replaced, of course.
The compact battery is rated at 300mAh, and from my vaping, seems to be inline with this claim. At just under a full charge with my DCT, I was able to measure the output voltage at 3.32v. I was unable to get a reading at full charge.
Because this is an automatic battery activated when inhaling, there is no need for a shutoff switch. It is also not conducive to using with atomizers, as they will continue to burn beyond inhalation.
With a cartomizer or tank though, this small package does indeed provide big things. It produced surprisingly good vapor volume and taste from my carts and tanks.
One thing I managed to find out while testing this device, it will automatically shutoff after approximately 5 seconds of activation. No, you still shouldn’t use atomizers!
Sitting under my Depth Charge tank, this PV looks freakishly small!
You can outfit the SD mod with whatever you like (not including atomizers)…be careful though, it could get top heavy!
What I think of the SD Keyring
Nothing I would rely on, or recommend to someone who is entering the eCigarette scene by far. If your looking for a simple, backup device, this might fit the bill.
- Size – The SD Keyring is the stealthiest of them all.
- Price – Awesome performer for the price.
- Activation – Auto “suck” activation is convenient for a stealth vape.
- Size – Did I already say this thing is really small? Sometimes, good things do come in small packages.
- Because this is such a small device, it could easily be lost?
Final notes on the SD Keyring
No, it’s not an all day vape, nor is it the most flexible PV mod. But than again, it wasn’t meant to be. The SD Keyring is a conveniently small device that performs great as a stealth vape, or used as a backup.
