Well seeing as you were interested in it, thought I would include a bit about MTL even though I vape DTLthanks for your review and also lately you've been including specific thoughts on mouth to.lung which I for .one greatly appreciate!
I received the efest luc6 unfortunately it seems amazing warehouse did not.fully check the device so it appears notbto be working fully.
Slot 1/6 charge at 2a 2-5 1amp.max unit has a 4 amp so you can do
1/6 2a each
1-4,2-5,3-6 or any variant of.4 bays at 1a each
All bays .5 each
I haven't set the Bluetooth up
Theh don't have a regular.app in the app store. They have an enterprise stand alone download that requires a blanket trust and installs from.a Chinese website. I don't know if what they were thinking but I don't trust them enough to.jnstall..an unsigned app.on. IOS
So..with the issues and the app ridiculousness I am probably sending this back
I got the Luc6 from Amazon UK and it works just fine, very fast at charging the batteries, although they do get a bit warm unlike the i4 but they soon cool down once they have charged, and being an Android user the App works as well, just have to remember to switch BT off after use otherwise it messes up the WiFi as noted on my Router logs (phone keeps disconnecting/reconnecting).
with the i4 bays 1&3 and/or 2&4 are used for matched pairs, but I think on the Luc6 they are 1&6 and/or 2&4 and/or 3&5 but it doesn't say anything in the instructions about it.
