Getting to know the Marvec Priest AIO90

Maybe you have never heard of Marvec, I know I hadn’t until I stumbled on there booth at the ECC show back in August 2017. Well let’s just say there booth left an impression on me and I put them in my show report, just look at there stab wood mod.

I made an album with some of there other products you can check out: https://imgur.com/a/8wivE2K

I left a card with Nic and a few month later he contacted me about a review and of course I was on board. I was actually expecting different products but when I opened the package for the Priest AIO90 my first thought was, wow, this is nice. I then went into the owners manual to check the specs and it read 18650, 20700 and 21700 compatible….ummmm, Hellz yeah…..oh wait, misprint in the manual, only takes 18650 so my excitement went down a notch. I then looked at the accessories and wait, what is this, a RBA for single coil that looks to be Baby Beast compatible, excitement right back up again!

I got the black resin version and let me tell you this thing is a beaut and the resin has that nice satin texture that feels great. Mine had a little rattle on the door of one side but settled in after a few weeks to hardly noticeable. Both panels are removable and you will need to do so to remove the battery.

The pic on the bottom left the space under the fire button is to put a spare coil…slick.

The included drip tip just would not do for me but luckily it is a 510 so I had plenty of options and they all fit just right.

Comes with there own baby beast compatible coil 0.20 ohms rated from 40 to 130 watts, best from 70 to 90 watts but whatevs, there is a single coil RBA included!

Easy to fire with either my thumb or middle finger, whichever way I picked it up finding the fire button was never a problem.

Building the RBA

The problem with the RBA is you will have to build on it without a base unless you have a baby beast compatible tank already, that way you can use that base. You will have to remove the thick o’ring first though like the pic below.

That will of course make it easier but if you don’t have a baby beast compatible base to build on I tried it without. The trick is to do a spaced coil, spaced coils do not have to be dry burned to work out the hotspots so you can build and wick. Just make sure the coil is not touching anything on the deck and has sufficient space from the posts.

Both of the above builds works great but my favorite was my first build, a 5 wrap 2.5mm post 26g dual core with 36g wrap fused kanthal clapton. Since it was a contact coil I built it on a baby beast compatible based to work out the hotspots.

This build was crackling good, so good in fact I was on the phone with a friend who could hear the coil crackling. He asked me what is that, I told him it was the new Marvec Priest AIO90 with the RBA section installed and I was loving it. I used that first build for close to 2 weeks and everytime I reached for the Priest it was like I was getting a blessing, flavor and all around performance for an AIO is the best I have experienced using the RBA section.

Building on the RBA is fairly easy even if you don’t have a baby beast compatible base although that does make it easier and safer. All the builds came out between 0.22 and 0.30 ohms and the Priest fired them all with ease.

For me the RBA base made the whole kit that much better and the performance was at another level. It has the added benefit that it can be used in baby beast compatible tanks and unlike Smok’s baby beast RBA you don’t have to use a bigger glass. You do have to change the bottom o’ring though, just remove the thick o’ring on the RBA coil and replace it with the bottom o’ring of a baby beast compatible coil. I did use it this way in a couple of baby beast compatible tanks like the Squid Peacemaker and Vaptio Frogman XL and got great results. It is a tighter draw than the Smok baby beast RBA and Advken Dominator RBA but both of those have compatibility issues with other baby beast coil tanks.

The premade coil and other baby beast compatible coils 

After probably a month with various builds on the RBA I knew I had to try the coil Marvec includes and sells in a 5 pack at a good price. Flavor and clouds are decent, about as good as most baby beast compatible coils. I was already spoiled by the RBA coil though, the premade doesn’t match it but there are hardly any premades that will match a good RBA with a great build.

I found that Eleaf coils like the HW1-C will work with no problems, you just have to replace the bottom o’ring with the thicker one that comes with the RBA or Marvec’s own premade.

You won’t be able to use some of the newer coils from Eleaf or Joyetech that use the mesh or net as those coils are just too big. I was able to use the new Smok V8 Baby Mesh coils though but installing it is a little more tricky due to the size, the coil won’t fit through the bottom hole, it is too big. I found a solution though.

[​IMG]

You first replace the bottom o’ring from the V8 Baby Mesh coil with the one from the RBA or Marvec’s premade, they do include a spare. Install the chimney first then screw the coil onto it from the inside. Then push down until the bottom o’ring is seated and screw on the bottom ring which is used to secure the coil and make your negative contact.

This is my first experience with the Smok V8 Baby Mesh coil and with it being 0.15 ohms might not be the best match for battery life. Took a little while to break in and with a fresh battery would get dry hits when chain vaping on my 3rd hit. After it broke in though the dry hits went away and wow is it a tasty and cloudy vape, you would be shocked what it puts out. Still not the equal of the RBA coil but I have been using it for the past 4 days and it is really enjoyable.

What’s not to like? 

I lost track of time and just saw I have had the Priest AIO90 for almost 6 weeks with daily use. Really the main thing is the condensation needs someplace to go and will settle mostly behind the door on the USB side. There is a airhole to the side but condensation always finds a way to settle behind that door.

[​IMG]

I need to clarify that the pic above was the worst example while using the Smok Baby Beast mesh coils. That coil burns through juice like no other and the airflow is also the loosest. While using the included premade and the RBA section the condensation build up was minor. With that said I would not recommend the Smok Baby Beast Mesh coil for use in the Priest AIO.

It never gets into the battery compartment or into the USB as that is raised. It is something you have to wipe down daily though but is never noticeable on the outside.

I still have a little rattle on the panel where the power button is, was worse when I first got it. I do consider it a minor con but it should be mentioned.

A base should be included to build the RBA section on for those who do not have a compatible tank. Just from a safety standpoint it is important to note so you can check your ohms and dry fire your coil.

Battery life

With the RBA or a prebuilt coil in the 0.25 to 0.30 range the battery life is great, really one of the few single 18650 mods I am willing to use. With a lower ohm coil like 0.15 ohms it is not as good but I can get through half the day with a single 18650. I measured 3.48V when I got the low battery warning and it stopped firing while using a 0.15 ohm build. 3.33V when using a 0.27 ohm build.

I used the USB to charge it a few times on the road and no problems there. It is a passthrough charge so you can vape at the same time. While it is always recommended to charge with an external charger I can confirm it worked fine and is claimed to be 2 amp charging.

Overall the battery life is great for a single 18650, I had no complaints there and I am someone who hates single 18650 in most cases.

Final thoughts

I was surprised when I saw the date I received the Marvec Priest AIO90, nearly 6 weeks and it feels like I have had it for maybe half that. I have really enjoyed my time with this little gem and it mostly has to do with the performance I got with the RBA coil. Don’t get me wrong, I am really enjoying the Smok V8 Baby Mesh coil now that it has broken in but that RBA coil…..ohhhh yeah. I don’t think there is a day that went by that I didn’t pick up the Priest and give it a vape and I can’t say that about all the other items I have in for review. I never thought there would be a single 18650 mod I would enjoy again but that is not the case here.

The Priest is a looker as well, I walked into a local vape shop to get some supplies and one of the employees asked me what I had in my hand. I handed it to him and before I knew it all 3 employees were around just oohing and ahhing and all 3 said they had to have one. This is a vape shop with all the high end goodies as well and I was a little surprised at the reaction but the Priest sells itself. If you see it in person and to try it out you will be convinced you have to have one as well.

I generally don’t rave about products with the exception of those that just perform to another level. The Marvec Priest AIO90 is the best AIO device I have personally ever used but keep in mind I have never used a Billet Box. I am thinking if the Billet Box works like this though I can now understand why they were so popular.

Make sure you get the version with the RBA section, they sell other version with just the prebuilt coil which is still good but not RBA good. If you have a favorite baby beast compatible prebuilt coil though it will still perform, just make sure it will fit, not all of them will.

Even though I didn’t get the stab wood mod from Marvec this came out so much better than I expected. There is no money or commissions for me with this review gig but the pleasure of getting an item I will continue to use and enjoy. Yeah, that makes it worthwhile and thank you to Marvec for sending me this surprise. Really I just do reviews as I was tired of getting burned by YT reviewers who sometimes only spend a couple of days with a product. I don’t accept money from mfg’s to do a review and if they can’t wait 3 to 6 weeks for a review then don’t send me products, simple as that.
