    SmokTech usb 510ego passthrough

    Posted by Miss Di on Nov 20, 2018

    I have been vaping for over 5 years and this is my first SmokTech product and first passthrough battery...and i love it a bunch. It last all day without any issues with my Kanger protank ll mini. Wish I would have done it sooner. The white cover feels smooth and I dot believe the color willwear off,so in a year I should still be looking good.

    The only backup you'll ever need. This is the one I keep in the car or coat pocket. Packs enough heat to fire a dual coil. My only wish is that it had Ego-T option to earn a solid five stars.

    Best Battery Quality yet!

    Posted by Aaron on Oct 27, 2013

    This battery has been around since order for over six months and still works as new! It last all day on a full charge and the usb pass-through feature is great. I've had quite a few different e-cigs and batteries such as Blu, Mistic,v2, J tech, and vivi nova and this is one of the best yet. Will definitely buy another whenever this one finally gives up.

    Fully Satisfied!

    I took care of my ego battery very well, in fact I babied it because I am newly off cigarettes. Not even 3 weeks later, the button quits working, and I'm out a battery :( Won't order this again

    Great little battery

    Posted by Tonya Mosher on Aug 15, 2013

    I've tried various sorts of batteries and seriously, this is an awesome product. I vape it all day on a single charge and I'm NOT a light user. If you're on the fence between this and a smaller manual or auto cig-a-like. Go with this, just do it. The battery unit itself really isn't that big, a bit shorter than some of the longer (xl) pen styles I've used. A bit longer than a cig-a-like. And it's thicker, but you can still keep a pretty low profile with it. It's thinner than most highlighters.

    As a previous Variable voltage mod user (it broke on me, bummer I loved that thing), I'm not disappointed in the slightest. This little thing has some serious power. Pair it with a low res or duel coil juice delivery system, and it'll knock your socks off. I'd even compare it to high voltage vaping. Very nice.

    Works well, but paint job is poor

    Posted by Hugh Messenger on Aug 14, 2013

    Great battery, haven't run out of power since I got it a few weeks ago, just plug it in to my laptop USB when I'm working. Only complaint is I got a black one, and within a week it was atainless steel one - the paint job just scratches and flakes off.

    Good battery

    Posted by Brandon on Mar 21, 2013

    Battery worked great I can’t speak on the life of it yet. I really like the USB pass-through at the bottom. Not having a 510 charger, being able to charge/run it through the usb is great!

    Great Battery!

    Posted by MJ on Dec 30, 2012

    Great battery..plenty of staying power (even for this previous 2 pack a day puffer!!) and the added convenience of recharging/vaping at same time. Nothing negative to say about this one. Didn't order my first from EC but will be getting any future ones from here. The price is always!
