My sister-in law had the same question so I sent her the following. It relates to a US vendor but the descriptions may help.
Easy Vaping Is one of the better web sites for vaping hardware but Joyetech hardware is generally mfg.
by Kranger and should be available at most vaping shops.

Nicotine concentrations:
2.4 % or 24 mg/ml unfiltered cigarette
1.8 % or 18 mg/ml filtered full flavor cigarette
1.2 % or 12 mg/ml filtered light cigarette
Kanger Recommended Resistance
1.7-1.9 (1.8 ohm) - 3.1-3.4 volts--- standard li ion battery
2.1-2.3 (2.2 ohm) - 3.5-3.8 volts--- variable volt or standard li ion battery
2.4-2.6 (2.5 ohm) - 3.9 -4.2 volts--- variable volt li ion battery
2.6-3.0 (2.8 ohm) - 4.3-4.7 volts--- variable volt li ion battery
Coil/wick life
Our experience is about 60 ml. e-liquid before toss and change and that is the reason for the extra coil
units. Generally the wick gets clogged with non-vapable krud.
The following are components Sandy and I use and are of good quality and trouble free:
Part: Kanger T3 eGo Bottom CC (Coil Changeable) Clearomizer, Black- $6.49
Part Number CKEGO2.4T3Blk--- purchase 2
Description: The Kanger eGo T3 is a 2.4ml Clearomizer with a bottom coil to reduce dry hits. It still has a
replaceable coil like the T2 but it is inserted at the bottom of the Clearomizer. The T3 is compatible with
eGo/eGo-T/eGo-C/eGo Twist battery and should work with any eGo compatible battery. It has a 2.4ml
capacity and scale on the transparent body so you can see clearly how much e-liquid is left. The
advantage of the Coil Changeable clearomizer is that its coil can easily be replaced and at a lower cost. It
has 2 detachable parts: clearomizer body, and the bottom coil unit. The bottom coil unit can be easily
screwed on/off, so you can add e-liquid and/or replace the coil unit when it's burnt out or needs replaced.
Resistance: 1.8 ohm +/- .2 ohm.
Part: Kanger T3 Bottom Coil, CC Replacement Coil 1.8 ohm Part Number CKEGOCcoil1.8T3---
purchase 4.
Part: Joyetech eGo-T 2 Upgrade 1000 mah passthrough battery (Stainless Steel) Item Id: B002 ---
purchase 1.
Description: Joyetech eGo-T 2 Upgrade USB passthrough has a built-in 1000mah eG0-T battery and a
USB port, which allows the user to vape during charging. The battery has "5-click protection" and
generally, the battery is shipped in the off position. In off position, the eGo-T will not function.
To turn the battery on, press manual button 5 times within 2 seconds. You will see the white LED flash,
which means it is on. To turn it back off, press manual button 5 times within 2 seconds, again you will see
the LED flash telling you it is off. "5-click protection" can protect the battery from being activated when
eGo is not in use.
