The e-cigcity passthrough has been designed and built in the UK.
It has been described as one of the most reliable, sturdy and best performing passthroughs available today. Backed with a 6 month return to base warrantee a problem free device is guaranteed.
Please note: To use this device from a USB wall plug, the USB wall plug must be rated at least 3.5 amp. Ecig chargers only tend to come with 0.5 amp USB wall plugs these will not have enough power to drive the pass-through.
