First impressions
 
Once I opened up the box and took the Xtar Rocket SV2 out my first thought was, hmmmm, that’s pretty compact, I like it. My second thought was, great travel charger as it is compact and includes a car charger cable which is a great idea.
I went ahead and placed it next to the smallest charger I own, the Xtar VC4 which I have owned for a while and has been a work horse of a charger:
As you can see not only is it smaller width wise as it is a 2 vs 4 battery charger but they also compacted the length by including a smaller LCD screen.
The more I looked into the specs I saw that it has user adjustable charging current in a wide range from 0.25A, 0.50A, 1.0A and 2.0A. Then what really caught my eye was the 0V Activation Function which can revive a battery whose voltage has dropped so low that other chargers would not repair, very handy for on the road.
At home use
 
The first batteries I was anxious to try was a pair of 20700 as there length can be tricky on some chargers. My Hohmbase charger has a hard time with them, you have to lift the positive end just right to get it to make contact. The SV2 took the 20700 just as easy as a pair of 18650 batteries, no problem whatsoever to install and remove….nice. In fact every battery was easy to install and remove thanks to the smooth operation of the battery sled, once of the nicest I have tried.
Of course 26650’s fit without any problems as well
You can even turn off the LCD by pressing and holding the button on the LCD screen:
The default charging starts at 1.0A but it easily changeable but clicking small button on the screen, click twice quickly to charge at 0.25A.
I know why the called it the Rocket, in the 2.0A mode I was able to fully charge a pair of Sony VTC5A 2600 mAh batteries in under 90 minutes.
I even tried the 0V Activation Function with an old Efest button top 18650 from my Provari days that I keep around for such testing. I measured the volts at 1.68 prior to installing in the SV2. No need to select a mode or anything, the SV2 simply starting at 0% and when it was done I measured 4.19V and worked on my Porvari just fine. This is a very handy feature to have with you if on the road or vacation and no access to new batteries, it will keep you vaping instead of turning back to a pack of cigarettes.
I used the Rocket SV2 as my main charger at home and never once had a hiccup, it works like a champ and is simple as pie to use.
On the road
 
For anyone who spends a lot of time on the road I think this compact and versatile charger is a must have. I waited until I had a long commute, this one being close to an hour so thought it was the best time to try it. Loved that it fit nicely in my center console, here is a pic for reference:
I started out with a pair of Samsung 30Q 3000 mAh which I measured before hand at 3.58 and 3.56V prior to installing them in the SV2. Turned on the timer in my car to accurately measure the amount of time then plugged in the car adapter, set the SV2 to 2.0A charging and away I went. At the start of my journey the SV@ read 15% on one bay and 10% of the other and after 55 minutes of driving it was at 84% and 80%. I then removed the batteries and luckily remembered my Digital Multimeter and measured 4.1V on both batteries, very nice.
Conclusion
 
Never gave much thought about a travel charger that would work in my car until I got the Xtar Rocket SV2 in for review. Most mod manufacturers warn against charging in there mods and really the USB is usually the weakest link and if you break that while on the road your screwed. That is why the Xtar Rocket SV2 makes so much sense, not only is it safer to charge your batteries with but faster and saves your mod from possible damage.
I would recommend this mod to anyone who travels a lot and even for those that just need a reliable home charger that is reasonably priced. I really came away from this review enlightened to a solution I hadn’t even thought about before.
The Xtar VC4 was my first real charger and has been flawless over probably 2 to 3 years. The Rocket SV2 actually seems a little better built so I am confident I will get many years of great service from it, my travel charger from here on out.
I searched the web for the best prices I could find, here is what I found:
China shipper: $25.97 shipped
I want to thank Xtar for sending me the Rocket SV2 to review. At first I wasn’t excited but didn’t know this would fill a niche that I had not thought of before. Kudos to Xtar for packing a lot of there excellent technology into a travel friendly package and including a car charger to boot…well done.
