On the subject of Eleif Isticks and all other mods that have built in rechargeable batteries built in.
Recently as I have written in another post, I lost a very expensive SMY 180S mod due to defective Sony 18650 batteries; that exploded / vented whilst being charged by the mod. Well at least they purport to be Sony as Sony categorically state they no longer manufacture VTC4 /5 batteries and I have been told on this forum that they are still being made, huh by which clone merchant?
The vendor of the batteries offered to compensate me for the batteries or replace them but how can I be sure that the replacement stock will be any better as Sony no longer make them? The compensation will not replace my destroyed Mod.
There is so much re-branded and cloned rubbish coming out of China now that no one seems to be assured that they are getting genuine articles and the authentication bar codes are being forged and fake websites set up for you to verify your product.
Remember folks, China is a Communist country, under Communism private property be it material or intelectual property does not exist. Any invention in China is supposed to be shared by the Communalism Communist Ideology and hence there is no Copyright unless of course they have been copied by the West and then all hell breaks loose. Hence all the cloning B.S. that goes on in China.
Back to the topic, I now refuse to buy mods that have no vent holes and have built in batteries. If I cannot remove the batteries for charging on my LUC Efest charger or on my Nightcore intellicharger I will not buy the mod. Now please do not get me wrong, My three Eleaf I sticks have not given me one ounce of trouble. I have all three 20W, 30W and the 50W, the 20W is in use by my wife and has been going well for over three months. I personally use the 50W and the 30W is in reserve. My issue is that internal batteries no matter how good the charging circuitry can malfunction and this is also true for other devices such as mobile phones, two way radio's and torches etc., Yet by the same token I have only heard one story of Ego style category 2 batteries venting or exploding whist being charged and that was years ago when vaping was in its infancy.
