Thank you for taking the time to view my review on the Laisimo F4 quad 18650 360 watt mod review. This was provided directly from Laisimo for the purpose of this review, more info can be found here: http://www.laisimo.com/goods-59.html
Update 12-4-2017: According to my contact at Laisimo they have resolved the "New Atomizer" prompt that was my biggest complaint. They have also removed the power bank feature as it was causing some of the problems. The F4 is now due to be released this month after they resolved these issues.
Please keep in mind that this is a pre-release version and my contact at Laisimo has assured me the engineers are still working out the kinks prior to final release. I have been letting them know any issues I have come across in the month I have had the F4, this is not just a review but a beta test as well.
There is a lot to get into so if you would like to save some time I go over most of the major points in my Pros and Cons as well as conclusion.
So you just got a Steamcrave Titan or Voltrove 41mm tank but overhang gives you the heebie-jeebies? Well Laisimo has a mod for you.....Enter the F4!
Look, No Overhang!!!!!!!!!! Woooot!
First impressions
First thing out of the box was it sure is lighter than what I was expecting but doesn't feel cheap. How light you ask (maybe you didn't ask but I am going to tell you anyway) at only 168 grams without batteries it is lighter than the Wismec Reuleaux RX200S at 173g, Lost Vape Triade at 191g and the Snowwolf 365 (4) battery mod at 180g. Loaded up with (4) Sony VTC5A batteries is weighs 360g which is not far off the Triade loaded with (3) batteries at 335g.
They used the same screen as there Wyvern 235 which is a good thing, I really like that color screen. It is easy to see even in direct sunlight, I think it is one of the better screens on a mod especially when you consider the price point.
You can even go into the menu with 3 clicks of the power button and see the levels of all 4 of the batteries.
It is pretty balanced just like in the pic, I took out all 4 batteries and measured 3.83 and 3.84 for all 4 batteries and repeated that on another occasion, it is evenly discharging the batteries.
Is it big....it holds 4 18650 batteries so yeah. They did a good job keeping it as small as you could possibly get it. Sure I got teased a little.... "hey can I get a beer out of your mini fridge" hahahaha, very funny....punks.
Here are some comparisons to the RX200S and Triade DNA250 so you can get an idea.
For holding an extra battery over these 2 triple battery mods it is not as bad as you would think. Is it as comfortable to hold, no but it is not uncomfortable to hold with my 8" paws.
It is actually more compact than the Snowwolf 365 quad battery mod but the Snowwolf has a better Reuleaux style configuration which makes it more ergonomic to hold.
The interface is basically the same as the Wyvern 235 with the exception that the F4 adds a Power Bank mode (yes it does work, I was able to charge another mod as well as my cell phone) the battery power screen I referenced earlier and a option to adjust the colors of the side Laisimo LED's.
You have a number of different options for the colors on the side including using the custom setting and leaving all the options as 0, this will essentially turn off the side lights.
I need to note and I also made Laisimo aware that at times the left side would be off but the right side of the LED would work. It would then come back on by itself for no apparent reason, this has happened 3 times in the month I have been using the F4. Doesn't affect performance any, just looks.
The battery door is secure but there is a little flex, I would have liked to see another couple of tabs on the sides rather than just on the end. I never felt like it was going to come off though but a little more secure would be nice.
Check out them guts
I have been known to take apart things and sometimes I put them back together. Ever since the "Press fit 510 scandal" I have been checking out mods to make sure my precious tanks aren't going to just flop off and crash. That is even more important if you are using one of these hot tub sized tanks, they are almost as heavy as the mod itself. Well, I am happy to report that Laisimo done it right, 510 is secured from under with a nut.
Good travel on the 510 and all my tanks sat flush and resistance was read fairly accurate. If resistance was off it was 0.02 at most which is a miniscule amount which won't make much of a difference if at all.
I try to fully disassemble every mod but the power button would have likely broke if I continued.
Power Performance
Now I don't have a tank that will take 360 watts nor do I want one, just not my style. I do have some Melo 300 coils which are rated at 300 watts and I know they will do 250 watts so I apologized to my esophagus and tried it......sigh. First I compared with my Triade DNA250 at 250 watts, both mods with fresh off the charger Sony VTC5A batteries which is at a minimum what you need to get those numbers. Really it was so hot that it is hard to compare but I was able to handle 1 second draws with just loads of clouds. From as much as I could take the F4 seemed to be a match, then I went to 300....idiot. At 300 watts on the F4 I was able to handle half second draws, not the He Man like 1 second draws I was taking at 250 watts. Whether it was hitting 300 watts I can't tell you for sure but it sure was hotter than 250. I will leave the oscilloscope tech ratings to the pros like @Anthony_Vapes and Daniel.
A couple of items are missing like a preheat or power curve. Not sure how popular those are but it would be nice to have the option. I did find myself taking a primer hit on a cold tank to get the coil heat up before taking a draw, this could be alleviated with a preheat but all in all it wasn't bad and minimal fire delay.
TC Performance
In general I have been happy with Laisimo's TC performance in past mods like the Snowwolf 200W Plus and the F4 was no different. It is not as accurate as a DNA or Yihi chip but it is pretty damn close and provides a very satisfying and smooth draw. At 430f I was able to vape my cotton dry without any burnt hits most of the time. On a few occasions with larger SS316L coils I would have to turn down the temp, sometimes as low as 415f to avoid dry hits. My theory is this was happening with large Alien coils and they tend to take longer to cool down, the F4 may have taken just a little too long to engage TC. With more normal SS316L coils I did not have this problem including some quad core fused claptons but they used 30g core with a 40g outer wrap.
There are 2 DIY modes in which you can set your own TCR, I did not get too deep into that as the preset SS mode worked so well for me but in my limited testing it worked reasonably well.
One thing I find to be a big con is wattage is limited to 120 when in temp mode, makes no sense to me and at times felt I needed more. I am hoping the Laisimo engineers can address this issue prior to release.
