^^^ Had similar problems with the dock
but just with the Apple cube or any other 1A and under USB cube. Honestly, it worked 9/10 times but took almost two hours to charge 0-100%. Pain in the ass as this was my only vape at the time (thus, charging time would cut into session time at
some point a casual day). Bought the ever-so-loved FF1 external charger--no longer an issue on my end.
As far as I know,
@chaosst33l, there was
one person here who
might have sent what he thought was a problematic dock in. Other than that, people have just been getting away from the iPhone white cubes (read: slow charge, also not always successful for folks, myself included). Just as you and many others did, I switched to using my Macbook for the time being. Then, I purchased the FF1 external charger.

^This is what you should be if you're really concerned and want to keep using the dock. Item description speaks for itself and it's proprietary AKA it betta' work
I know you probably don't to hear spending money will solve the issue. As per others, there are numerous options for charging.
