It's light and compact with a juicer and a USB charge jack for the 14550 which vapes great at 3,7v with a LR atty. It's "Perfect"!! Vapes great, less filling!
The mini USB jack is installed and charges perfectly! I put the jack under the bottle facing out the side. The second batch of bottles I got was shorter,,, another unintentional perfect fit! It's the same charger plug as my cell and I have plenty of those around.
The meter isn't needed but I got use to having it attached while testing and it fit... so I figured I'd add it. I have a separate switch on the meter to conserve power and stop it from flashing all the time.
The board fits just under the curves of the bottle and the battery. There's enough clearance for the meter to fit in sideways. In that same space, the atty could be recessed over the USB charge board if insulated properly. I had the larger USB plug wired in and stored in that space and it folded out for charging w/o a cable. It could have a jack and plug for charging versatility. There are a lot of options!
The charge light stays on when main power is on and dims as power decreases so you get an indication w/o the meter. I use the Perfect as kind of a pass through a lot so it's always charged up.
I can charge it from my Tekk mod!!
