Any tank/dripper with 510 connection will fit. 510 connector is the USB of the vaping world 

My vaporshark setup with a dripper. If you use a tank, it's unlikely you'll go till 40w.

Yes you'll need to drip juice after few puffs. I usually use this at home & when I'm out, a tank is more convenient. Think of it like a cigarette in a box & those that you need to roll yourself. That's the nearest analogy I can think of. Of coz, smoking is history liao 

Really quick explanation of the differences here, you have the RDA (Rebuildable Dripping Atomizer) and the RTA (Rebuildable Tank Atomizer). Many RDAs do not have a huge liquid capacity and would be required to be held upright most of the time to avoid leakages as they do not have a "tank/container" to hold the liquids in. It is called a RDA/dripper because you will be required to refill the liquids after a few vapes due to the lack of storage. RTA on the other hand will have a tank to hold the liquids hence the ability to carry/store more liquid and since it's secured it is possible to commute and move about with it tucked in your bag without the fear of spillages. With that being said, some RTAs have the tendency to leak despite it's intended design so I wouldn't say all RTAs are leak proof. However as stated earlier, main difference is RDA = drip e-liquid/juice after every few puffs and RTA = higher liquid capacity.

Also the term Rebuilable means that you are able to rebuild your coils which is different from tanks such as the Aspire Nautilus and Subtank Mini as they have replaceable coils (except when a rebuildable deck if provided, in this case the Subtank Mini)

RBA = Rebuildable Atomizer / RDA = Rebuildable Dripping Atomizer / RTA = Rebuildable Tank Atomizer.
When they say RBA it means it's a rebuildable and basically it's like a blanket term for RDAs and RTAs.

I cannot confirm if Aspire replaceable coils last longer than replaceable coils of other makes but generally coils that are built/rebuildable will have a longer shelf life if you maintain it. I haven't read your previous posts and I assume you have not started vaping and if that's the case, don't jump into rebuildables just yet but rather try out a set with changeable coils until you're ready

Since you're into eGrip's RBA, you will encounter leaking juices from the bottom of the airflow hole... Please ensure that you stuff more cotton to the coils, enough to cover 2 out of 4 liquid holes... That will stop leaking...

I almost gave up on eGrip many, many times until I found the solution... The last attempt cost me like 3 hours and quarter bottle of Rude Beer liquid.... 

u r using the 0.5ohm coils based on ur watt settings..

coils will deteriorate over time, same like light bulbs..

the difference is, light bulbs is not in direct contact with liquids..

vaping coils do..and more over, liquids contents will build up carbon on ur coils..

overtime, build up carbon will become gunk and affect ur wick/cotton..

take out the cotton, dry burn ur occ head by firing no longer than 5 seconds, with 5 seconds interval from the next firing..

do this until u can see the coils, not the balck gunk.. make sure u dont fire more than 5 seconds as the longer u fire, the faster ur occ head insulator will deteriorate as well and will melt too.. this will render ur occ head useless..

once the coil head is clear, stuff in new cotton, wet em up with ur choise of liquid and fire up to look at the vapor production..

then, off course fill up ur tank, and ur good to go..

U can get 10ml @ RM10~RM15. Or 30ml around RM30+. Vaperslegacy @ Klang do lelong stock @ RM1 juice, got 30ML and 15ML.
