I’m happy to be back with you for another review for JWEI (eleaf). This time I was sent the Eleaf iJust P40 kit in order to provide you with a fair and honest review. The P40 is a simple, versatile, and portable kit. The kit consists of the iJust P40 mod that has an internal 1500mah with a charging rate of 5V/2A. I may have to plug it into my USB tester and check that charging rate later. You can probably tell from the name that is has a maximum output of 40 watts but is also adjustable from 10-40 watts in five watt increments. It’s a simplified output system with this type of adjustment and may not be a good fit for those that need to adjust output in .5 or 1 watt increments. Instead it adjusts in 5 watt increments. The P40 has what they are calling an intuitive battery level indicator which in reality is a three color battery level indicator that I’ve seen on many pod type devices.
Also included in the kit is the D20 Pod Cartridge. The D20 looks similar but is different from the GTL D20 pod tank that I reviewed with the iStick i40 kit. The main difference is that the GTL version had a 510 base that the pod connected to with magnets where the D20 is just the pod portion. It holds 3ml of liquid in the version I received but there is also a 2ml version available I’m assuming for the UK market. It is compatible with all GTL coils and is targeted at RDL and DL vapers.

INITIAL THOUGHTS:
I haven’t been doing reviews for Eleaf for very long but I continue to be pleased with their products. There is something attractive to me about a simplistic device after having reviewed and bought many other more complicated devices. The P40 comes in a basic package that I find appropriate for a device like this. Instead of the usual slide out box or two piece box with a wrap, the P40 comes with a frosted plastic cover on the front where you can only make out the color and the basic shape of the device. The name iJust P40 is printed on the front in large green lettering and there is the large warning on the bottom that has become common place with a lot of the samples I have been receiving. The back side of the box gives a contents list, specifications, company information, and another large warning on the bottom. I find it interesting that Eleaf included the filling hole diameter of 3.2mm in the specification list. I don’t know that I’ve ever seen another sample where this information is given.
To access the device you simply lift the plastic cover up from the convenient cut out on the bottom. The back side stays attached so the cover doesn’t come off completely. Initially the P40 with the D20 pod is sitting in a foam insert. There is not a coil pre-installed in the pod. Lift the foam insert and underneath is the user manual, warranty card, two coils, and a USB-C charging cable. The two coils included are the GTL .4 and .8 ohm coils. The GTL series coils are the same ones that came with the iStick i40 and can be used on a few other Eleaf products.
I received both the black and yellow versions but the yellow seems to show up much better for picture taking for the most part. One side of the mod has the iJust P40 name printed on it while the opposite side has the Eleaf name printed in a different orientation for design aesthetics. The body is made of plastic but the way that it is finished gives it the appearance of being made of a softer material. It is very smooth to the touch but not soft. Near the top on either side is the airflow inlet. The airflow is adjustable by moving the protruding tab on the back from side to side. The sliding control is a bit stiff at first and you should have no issue with it moving accidentally if carried in a pocket.
The P40 is a pod mod so of course it has a pretty standard pod mod opening on top. There is the metal ring that the magnets from the pod attach to which is secured by four small torx head screws. Below that are the two spring loaded contacts that make connection with the coil in the pod. There isn’t an airflow sensor in this one since it does not do auto draw. I think this would have been a good feature to add since the P40 only weighs in at 65 grams.
The bottom of the P40 is where we find the USB-C charging port that allows you to charge the 1500mah battery at a rate of 5V/2A. It seems like an odd place to me for them to locate the charging port but as lightweight as this one is, it might not stand up to charge anyway. Also located on the bottom there are three battery vent holes. Always a good safety feature to have in case a battery were to vent. It’s a small detail but I like that the USB charging port is recessed so when you sit it on a table or something the port isn’t making direct contact and picking up dirt and debris.
Now on to the front of the P40. It is adjustable using the + and – buttons located near the bottom of the mod. It is adjustable in 5 watt increments from 10-40 watts. It doesn’t have a standard screen. Instead as you adjust the wattage then that number is illuminated on the front of the mod. There is not a standard display screen with puff counter, resistance, etc. They were going for a very simplistic design with this one and they have accomplished that. The button operation is also simple with just pressing the fire button 5X to turn the device on or off. Above where the 40 watt indicator is located there is a single indicator light which tells you that it is being fired as well as telling you the battery charge level. The three battery levels are as follows.
The pod tank included is the D20 tank which has a 3ml liquid capacity for the standard kit which is what I received. The D20 is compatible with the iJust D20 and the GTL D20. All three use the GTL series coils. The top cap has a slide to fill operation. There is an arrow on the top cap indicating which direction to slide the cap to expose the 3.2mm fill port opening. If you look on the bottom of the top cap in the first picture you can see that there is a ball bearing on the underneath side and when you close the cap then you can feel that ball snap into place. The top cap has a decent amount of resistance without making it too hard to slide.
In the second picture below you can see that there are four magnets on the base of the D20 tank. These make contact with the metal ring in the pod opening on the mod to hold it in place. Honestly, I wish that the magnets were a little stronger. With a small device like the P40, I find myself resting a finger on the back of the tank and have popped up the back side of the tank multiple times until I trained myself not to rest a finger on the tank. The coils are a simple push in style. The drip tip is a 510 style but there is a shoulder built into the top cap so some tips that are wider on the bottom will not look right when used on this tank.
The coils included in the kit are the newer mesh style. One is a .8 ohm mesh which is rated for 12-18 watts for MTL and the other is a .4 ohm mesh which is rated for 20-30 watts for RDL use. These are the GTL series coils and are compatible with the iJust D20 and the GTL D20 tank.
FINAL THOUGHTS:
Eleaf set out to make a simplistic device that is user friendly and performs well. In my opinion they have accomplished just that. The 1500mah battery seemed to charge very quickly and when I attached my USB current tester it showed 1.72 amps while charging which is pretty close to the 5V/2A rating on the P40.
At a weight of 65g it is indeed very lightweight and portable. The sliding top cap clicks into place so I can’t quite figure out how it happened but one day before leaving work I put both of the P40 review samples in my coat pocket. When I got to my car and reached into my pocket to retrieve them, I got a wet hand. One of the sliding tops had slid open and dumped a couple of ml of liquid into my pocket. So, I guess the morale of the story here is to be careful when pocket carrying this. My best guess is that it somehow got opened prior to sticking it in my pocket since there wasn’t anything to catch on in my pocket.
Due to the small size of the P40, I had a tendency to rest my pointer finger against the back side of the pod tank and it would often lift up some. If the magnets were a little stronger then I feel like this wouldn’t happen.
I didn’t mind at all that the P40 adjusts in 5 watt increments. Both coils were very flavorful. I used the .8 ohm coil with a NET tobacco mix and very much enjoyed the flavor production at 15 watts. I was able to turn it up to 20 watts for a little warmer vapor but felt like it took away from the flavor production some so defaulted back to 15 watts for better flavor production. The .4 ohm coil was very good also and for this one I used an RY4 mix. The flavors came through very good with the wattage set at 25 watts. I ran both coils with the airflow wide open. The .8 ohm coil restricted the airflow due to its construction but with the airflow open it was a very nice loose MTL. The .4 ohm coil allowed much more airflow and with the airflow open it produced a nice RDL vape. I liked that the sliding adjustable airflow control was on the back while the actual airflow inlets were on the sides and had no issues restricting the airflow with my hand.
The P40 doesn’t have a puff counter so I can’t really tell you how many puffs I got with a charge but refilled both pod tanks several times and felt like I got very good battery life using both coils. For a 1500mah battery it seemed to last a long time. I ran each until the battery level indicator was red then would recharge and start over. I had zero leaking during my time using them.
I’d like to thank Eleaf and Adela for sending the Eleaf iJust P40 kits for this review. As always a big thank you to the readers. Below is a link to the Eleaf website. They have been around since my early days of vaping and one of my very first mods was an iStick. I get a little nostalgic when I use their kits.
