Got one & it works pretty good. Out of the box into the charger took about 45 minutes for a full charge. That charged 2.5 automatic batts. Back in the charger, a little over 4 hours for a full charge. I'm charging my 2nd battery right now, got the 3rd waiting. Battery charge time is about 2 hours. That's ok, I get about 3 hours(normally) out of a 401 battery.
Once the battery is charged, the green led comes on briefly & then flashs green to red until you unscrew the battery. After about 2 hours, keep an eye on it. The flashes are slow & if you don't pay attention, you won't notice. If you want to leave the battery in that slot, just screw it out enough to shut off the led, no more, or the lid won't close.
Manual batteries, not without removing the button. It is possible that you could file a slot to make it work, but I'm not going to tear this up to find out. I just got it!
It holds 4 carts, 1 cart with atomizer, 1 battery in the charging slot & 1 battery behind that.
It's black plastic with a rubbery kind of feel to it. To open, the one I got, you have to put a thumb on both sides & push up. It has a locking clip on it.
Only problem I noticed was when the case battery runs out, if you are charging a battery, you won't know the case is out of gas. After 2.5 hours & it still hadn't finished the 3rd battery I unscrewed the battery & the led stayed red. I wish it would flash or something to let you know the case is empty. But, If I can get 3 batteries charged on one case charge, it won't matter. My work day takes 3 batteries & I use a passthrough at the house. I've got a 901, a 510, a 702, & a J118 PCC(or my manual 401 batts) I can use if I go anywhere else.
Overall, so far, I really like this. I'd like the case even if it didn't charge batteries!
One last thing, I took a whole 702 & it's too long to fit in the back battery slot & the battery would be to short for this to charge it. Had to dig it out with the atomzier.
Only a small sliver of the 702 batt was showing. I think the 702 batt is about the same length as the M403? It's possible that the M402 battery would work, but I don't have one to try.
Kudos to Kevin @ Sharp Smoker for finding & stocking these. I know that another supplier is waiting on a 'smart' 401 PCC & I will get one of those also when it breaks. I like the way the 702 PCC works.
Hope this helped. If you've got a question, fire away.

PS. 2nd battery just finished & 3rd is now charging. I'll edit this later & post how many batts got charged this time. I know that the first charge on a PCC is normally not as good as the rest.
Pt. 2
Ok, an hour in to the 3rd battery charging, I unscrewed it & screwed it back in. No joy. Got 2.5 charges this time also. Now I'm going to see if it will charge a battery & the case at the same time.
Pt. 3
Yes, it will charge batteries while it is charging. I finished up battery # 3 & charged a 4th one while the PCC was charging. It took an extra hour to charge the PCC, but the batteries seemed to charge quicker.
