Definitely i had the SD, Tornado a few micros and in the end I decided screw this and bought the pass through. Never looked back. It holds a great charge for when your away form a pc but when your at one you can charge, If your in a car you can charge (just get a car adapter with a usb port on it they cost about £1 form ..you guessed it Poundland) then you can vape away in the car or if you drive for a living.
Also you can just buy a usb wall plug they to cost a few £ and you can stick the cable in there and bam your now vaping straight from a wall socket woohoo.
Only regret was i bought a new one a few weeks before the new ego c pass through came out and i would have preferred the option to turn it off as i carry it in my pen pocket which often hits the button frying my atty. so something to think about. Id rather spend a few quid extra and have the option at least, you dont have to use it.
That is good for me
As i have a iphone i can just use the adaptor i have when at home and i have an adaptor in the car to as i travel alot
So its a win win in my books roll on pay day as i want to get one of those cases to keep everything in aswell, my glasses case i was using is starting to fall apart
