Battery - it charges really fast, however - since day 3 it has been a struggle, You can't vape, it says battery empty, You put it on charge - and it still has 46% - like wtf. Alex is a cannabis enthusiast, long time vaporizer lover, writer and filmmaker. He is also a board and video game nerd with a penchant for hosting a weekly board game night. Partygoers have been heard saying things like “is anyone else going to show up?” and “I don’t think I can make it next week”. He strives to make people laugh at every opportunity and sees cannabis as a helpful tool in doing so. Coils for light pod give more flavour (in the beginning) last long, even with sweet liquids, however it looses the taste after few days, (and I don't vape much) vape becomes like a ghost of flavour that You had before. Didn't even bother to use dark pod as it leaks, and also I hate the fact that it's so dark, that You can't see how much liquid You have left. The mouthpiece is part of the included 4.3ml capacity RPM Standard and 4.5ml capacity RPM Nord pod (depending on the installed coil) which fits in snugly with the body of this device. There are no issues with pulling out and re-inserting the pod to the body, they fit perfectly and sits flush with each other.

I personally found this to be a cheap & nasty pod system. The side pieces with the colours on peeled off & it wasn't any good as MTL or DTL.The display and fully adjustable settings are spot on and make the unit super versatile. Again it is leaps and bounds ahead of any of it's rivals at this price point. For the Mesh and Triple coil options, we recommend 60% and 70% VG e-liquids, while the DC MTL, Quartz and SC editions will perform best with high PG e-liquids of 50% PG and above.

The relative centrifugal force (RCF) or the g force is the radial force generated by the spinning rotor as expressed relative to the earth's gravitational force. The g force acting on particles is exponential to the speed of rotation defined as revolutions per minute (RPM). It has a respectable 1500ma battery that with most of the coils and careful use of power will last you all day. Rpm 40 wouldn’t turn on, battery has a defective solder. Ground lead disconnected from battery with no effort. I’ll post pictures of my solder if it’s successful, should be straight forward.I've tried pretty much all variants of Coil wattage, resistance. These coils are 0.6 ohm, used on a Smok Nord 50w with 50/50 juice, burning at 15 to 18 watts is my best combo to date. When the RPM is unknown and you are given a g force and radius ( r), you can calculate RPM using the following formula: RPM Formula

With a range of coil build options to choose from, these include the RPM Mesh 0.3 Ohm and 0.4 Ohm which produces increased cloud production with a larger surface area, the RPM Triple 0.6 Ohm which delivers for a fast ramp-up time, the 0.8 Ohm DC MTL coil as well as the RPM Quartz 1.2 Ohm and RPM SC 1.0 Ohm options for those who prefer reduced cloud creation.

Review: Smok RPM40

KEEP OUT OF REACH OF CHILDREN. IF SWALLOWED: Rinse mouth. IF ON SKIN: Wash with plenty of soap and water. Call a POISON CENTRE or a doctor/physician if you feel unwell. To avoid risk of fire, injury and/or damage to your E-Cigarette product or other property, only charge your E-Cigarette device with the equipment provided in your kit, or with compatible charging accessories. SMOK RPM 40 combines the advantages of both pod devices and box mods. It is small in size but has a battery capacity of 1500mAh and a power range of 1W-40W for you to adjust. The internal IQ-R chip shortens the firing time to 0.001S, and charging time to two hours. In addition the newly designed RPM Mesh 0.4 Coil is designed for both great flavour and excellent vapor production. I have a PhD in Pharmaceutical Technology & oversee the quality & safety of all products that we carry I have been trying for months and months to find the perfect pod system that does not just bridge the gap between MTL pods and DTL tanks but to do both and fill every section in-between. RCF or g force is dependent on the speed of rotation in RPM and the distance of the particles from the center of rotation. When the speed of rotation is given in RPM and the distance (r) is expressed in centimeters, RCF can be calculated by using the following formula. G Force Formula

There are two types of 2ml refillable pods that can be used with the kit. The Smok RPM standard pod uses replaceable RPM coils, for use with high VG e-liquids that are 60% VG or higher. The Smok Nord pods allow you to use the entire nord coil range, supporting high VG and high PG e-liquids. SMOK’s RPM40 does everything you could ask from a pod vape system and then a little more too! With battery capacity and wattage for any occasion along with SMOK’s fantastic Nord and RPM coil range, you’ve got a device for any instance that’s as portable and stylish as it is satisfying! We’re certain you’ll love the RPM40. Smok has always been known in manufacturing vape pods that are easily accessible to any type of vaper with the simplicity and ease of use that you just cannot compare with most of the vape pods available in today’s market. That trend continues with the Smok RPM40. Relative centrifugal force (RCF) refers to the amount of force applied when using a centrifuge. To convert revolutions per minute (RPM) to relative centrifugal force (RCF), or g force, use the following formula: RCF = (RPM) 2 × 1.118 × 10 -5 × r. Relative centrifugal force is dependent on the speed of rotation in RPM and the distance of the particles from the center of rotation. When the speed of rotation is given in RPM and the distance ( r) is expressed in centimeters, RCF can be calculated. I have tried at least 15 or so pod systems marketed at DTL & MTL and have found some beauties like the GeekVape Bident and the Lost Vape Lyra but not found one that will work perfectly as a MTL and DTL with no real sacrifices.Tried both tanks with the included coils. Vaped loaded 6mg cotton candy through the rpm tank at around 35watts and it produces great clouds and flavour. Same results using the nord tank with pod salt peanut butter 20mg at 20watt. The device is more airy than the smaller pods smok make due to the vents...something to keep in mind (less of a tight draw with this), but im incredibly happy with it and my poor nords might now be sitting on the shelf with my drag2, snow-wolf and species sub-om devices! Poor babys!
