A Quick Look at The SD Keychain ecig

Ripple Pod System Vape Kit is the Alternative to Cigarettes

I’m not sure what made me decide to buy one of these SD Keychain ecigs. I wasn’t really in the market for a small battery ecig- but something piqued my curiosity and the order was placed. The SD was created by Trog, the same Trog that created the original Screwdriver PV mod. The SD is a very small and pocket-able ecig with an automatic switch and 510 threads. At 300Mah and 3.7v, it’s not an all day device for a heavy vaper- but it beats a 510 stick battery in performance any day.

So far, I’ve put about 3-4 charges through my SD keychain and I have to say- this thing hits really well with an LR cartomizer. Included in the package were 2 standard cartos that tested at around 3.5Ohm. The cartos are prefilled, mine were “CML” flavor, which was a tobacco flavor. After a few pulls on the pre-filled cartos, I quickly threw on an LR carto with juice of my choosing. The SD Keychain produces nice clouds of vapor and is satisfying.

The battery charge lasts me between 4-5 hours, and it takes equally as long to charge.

The only negative that I’ve experienced is when I put on an atomizer. First attempt with an LR atty and it wouldn’t fire. Second attempt was with a LR HH 357 and it produced a small puff and then nothing- as if it was dead. Going back to the carto and everything was fine again. That’s not much of a deal breaker IMO as I would ruin the SD if I used an atty on it by over-dripping.

All in all, for the price this is a neat little unit to keep in your pocket, car or as a spare device for at work. It would be an economical way for anybody to easily decide if vaping will work for them. Since the SD isn’t a kit, nor a pass-through -this unit is not intended to be used as your only ecig. *If you are just starting out with ecigs- make sure to either get two, or look into more robust kits such as an Ego. The SD will make a great back-up, but you won’t want to wait for it to charge if it’s your only unit and you “were” a heavy smoker or are a heavy vaper.
