E-Cigs co uk has in stock Usb Pass
through Batts for both the DSE901'S and the White (and Black or Silver)Classic eCigarette USB Pass
Through Battery which say's Fits all Classic RN4072 and DSE801 atomisers.
I have just bought two for my RN4072 and neither will work properly with ANY of my RN4072 Atomisers and i have Eight including 2 New one's which i got about a week and a half ago.
Now there are other
threads in the Tech Problem section which have a lot of different people complaining about USB passthrough batts not working and there are a few theories including "if the atomiser has been used with an ordinary battery (which mine have) it may not fit correctly" and people are suggesting doing things like "fit a small piece of foil in the hole"etc.
I've ordered a new Atomiser which should arrive tomorrow and it will only be fitted to the passthrough's and if that does not work correctly i'm afraid they will be going back.
What's happening with mine is when i take a drag the light will flash 2or 3 times and then nothing happens. Then i'll try again and i may get a couple of drags from it then the light will stay on for about 6 seconds and it's dead again.
I do have an Usb passtrough which i bought last year from China and one which i bought second hand from an ECF member and they work fine with all my Atomisers.
'Tis a puzzlement.
