EHPRO Epoch S1 Tank Review | Vape Tank Reviews

The Epoch S1 tank is one of the newest tanks to be released by the EHPRO brand.

This brand became popular with the Billow RTA. Now they are taking their own chance at creating and manufacturing a high end sub ohm tank.

What’s New – EHPRO Epoch S1 Tank?

Some Concerns

One of the things that makes the Epoch S1 different is that has an RBA section included.

The tank can hold 3.5 ml of e-liquid and comes with two coils to choose from.

The tank comes with the 0.5 ohm Kanthal coil and a 0.2 ohm DIY SDC coil for your variable wattage needs.

It also includes the 0.2 ohm Ni200 which are used for your temperature control vaping needs.

Now there a few things that you can do when you are vaping with your new EHPRO Epoch S1. One of these is that you can vape with the 0.2 ohm Ni200 coil when using a temperature controlled mod.

Remember that you have to use temp control with these coils. They are not the right type of coils to use if you are not going to be using a temp control mod.

 I noticed that when I was using the 0.2 ohm Ni200 coil that there was a bit of gurgling and some spit back.

This is not something that I enjoy so I wanted to share this issue with you so that you would be aware before you used it.

I was not aware that this would happen and it was a rather unfortunate incident when I found out.

I was able to get a really great vaping experience with the Ni200 coil. I chose to vape at around 180 degrees with this one and I was able to produce some large sized clouds.

There are a lot of tanks that fall flat at this temperature and do not produce the clouds that I am personally looking for.

I noticed that this was not the case when this coil was used in the this tank.

Even though there was a little bit of spit back I would still recommend this to other users but if you hear gurgling I would avoid taking too large of a draw.

When I was vaping with the 0.5 ohm Kanthal coil I was able to have a different type of vaping experience.

Remember that this coil is recommended for vaping between 25W and 50W. With 25W your experience will yield a little bit of vapor.

At 30W you are still going to get minimal vapor but you are going to get a hint of flavor and some spit back or gurgling.

When I was vaping at 40W I was able to have a cleaner flavor and better vaping experience.

I got pretty good flavor here, but honestly it was not as good as the flavor that I got with the temp control mod and Ni200 coil.

I also noticed that there was quite a bit of gurgling and more spit back than what I had with the other set.

When you are using this tank at 50W you have to compare it to other sub ohm tanks that are available.

The vapor being produced from this tank is not the biggest.

It does produce a decent flavor, but this is not the best flavor that you will find.

When you are using this coil at this wattage you must prepare yourself for a constant spit back and gurgling.

I am not a fan of the spit back so I really was not as happy with the tank when using it for sub ohm vaping with a variable wattage mod.

However, if you are looking for the best flavor with the 0.5 ohm coil then this is the temperature where you need to use the tank.

The Good Things

There so many things that can be said that are good about the EHPRO Epoch S1 tank.

There is an RBA section. One of the things that is surprising with this tank is that the RBA section is actually included.

This is not the case with all tanks and is something that is pretty surprising when you are looking at tanks in this price range.

The deck has a dual post hole design. This allows for really nice air flow and a decent amount of juice flow.

While it is not the biggest deck, it is a deck that is going to work well for you with your single coil builds.

When you are using the 0.2 ohm Ni200 coil it is going to vape really well.

There is a little bit of spit back but the flavor is improved over many other options when using a temperature control mod.

You also get to control how warm the vapor gets which means that you do not have to vape at levels that are uncomfortable or not favorable for you.

Most users find that it works best at 180 degrees.

The overall flavor with the 0.5 ohm Kanthal wire is very tasty.

There are some issues with the experience, as you are going to find that it has a lot of spit back and makes a gurgling sound.

If you are vaping at around 50W it is not going to get too hot.

This makes the experience enjoyable the whole time. I prefer a nice warm vape and this never got hot, so that was a nice little bonus.

There are two large air flow holes that allow for superior air flow with this tank.

The Epoch also looks great. It will come with a stainless steel silver tank or a derlin black tank.

This is a tank that really looks great and can be used with many mods and still look great.

This is nice if you like to use different mods or play around from time to time. The black derlin drip tip that comes with the tank is also really nice.

This tip actually seems to have less gunk and buildup over time and that is a big bonus in my opinion.

With many of the stainless steel tips that I have used, I have found that there really is quite a bit of grime and build up on the tank.

This tip also stays nice and cool which is not always the case with a stainless steel drip tip.


Even though there are all of these great things, there are some things that I was not happy with when it came to the Epoch S1 tank.

One of the things that I did not like was the small capacity of the tank.

It is supposed to hold around 3.5 ml but in reality I was only able to use about 3 ml of e-liquid with this tank.

To me this is pretty disappointing as I was sold the tank with one thing in mind and what I really got was different and not as good as what was promised.

Even though this is a sub ohm tank it is not going to produce the biggest clouds either.

It is going to produce decent sized clouds but if you are trying to get those big clouds you are not going to be able to with this tank.

Sadly, because it is a sub ohm tank, it goes through the e-liquid pretty quickly.

If it had a slightly bigger tank capacity you would not run out of e-liquid all of the time and that is something that would make most vapers pretty happy.

Additionally I was not happy with the amount of gurgling and spit back this tank produced.

When I was using the 0.5 Kanthal coil, I got the most gurgling and spit back.

With the Ni200 coil I was able to vape with a little bit less but it still limits the way in which I would use the mod which is not something that I am happy with.

I also noticed that there was quit a bit of leaking when I was refiling the tank or putting in a new coil.

I personally hate to lose e-liquid since it costs so much so I always find it a disappointment when a tank leaks.

When I was changing the coil, the e-liquid actually leaked out of one of the air flow holes.

Final Thoughts – EHPRO Epoch S1 Tank

Overall I would rate the EHPRO Epoch S1 tank as being a decent choice for a sub ohm tank.

I will admit that it is not the best sub ohm tank on the market but it can adequately meet your vaping needs.

If you are looking for a sub ohm tank with a decent RBA deck or one that uses the Ni200 temp control coils then this is probably a great choice.

However if you are looking for something to use with variable wattage, then this probably not the best choice for you.

I also think that it is a good choice for you if you want an RBA and pre-built coils depending on the day or your mood.

The derlin drip tip is something else that I really think that you will like.

Even at the hottest temps you do not have to worry about burning your mouth. Plus it seemed like it was magically uncrustable.

It stayed so clean no matter how long I was using it. Overall the only negative things were the small tank size, spitting, and gurgling noises.
