Newbie battery question

dammit, choices. I also like the look of the variable voltage version of the plain USB passthrough they have there, for the sake of £10, too. Although I should imagine it canes the USB port a bit...

Yeah I have heard they are pretty good. Not sure what effect they would have on a USB port, but you could always plug it into a socket with a USB adapter...
 
You might want to try one of these from http://www.liberty-flights.co.uk/product.asp?id=98 before you spend out:

EGO VV PASS-THROUGH (MANUAL)


This pass-through offers variable voltage output, the 4 stages out power output are 3v, 3.6v, 4.2v and 4.8v.

Simply press the button 3 times in quick succession to cycle through the voltage settings. Cable length, 1.2 meters. You can turn off your device by simply pressing the Button three times in a row.

The LCD display colours are as follows:


Blue light - 3 voltage output
Pink light - 3.6 voltage output
Red light - 4.2 voltage output
Green light - 4.8 voltage output


To use this device from a USB wall plug, the USB wall plug must be rated at least 2 amp. E-cig chargers only tend to come with 0.5 amp USB wall plugs these will not have enough power to drive the pass-through.


eGo VV Pass-through - Black - £11.99
eGo VV Pass-through - Steel - £11.99
 
Well thanks everyone, looks like there are a few choices, if I wasn't so tight I'd try a few, as it is I'm going to give the britvapes one a go as it's closest to the ones I've seen in the US - but just get the one for now since they are only 650 maH and then hope an 1000 -ish one comes out eventually - (although that might start making them silly sizes with the additional lcd bit).

As a side note re the high ampere usb wall chargers - I've found the chargers I've got for thirsty android smart phones tend to be rated for a couple of amps and do the job pretty well, if you've got any lying around.
 
The ones for a certain fruity product do the trick as well, just switch cables
