It’s coming to be practically required for firms that make sheathing mods (specifically those with detachable batteries) to supply a common 510 adapter as an optional added.

I believe this is a fantastic suggestion as it enables individuals to relocate from sheathing systems, to various other storage tanks, whilst still preserving several of making use of their financial investment.

With many firms this is an optional added, however I was interested to see that the Hotcig RDS Double System features it in package.

As a matter of fact not just does it have the alternative of utilizing it as either a mod or a shell, the gadget will in fact inform which one you are utilizing and also change properly!

Extremely expensive.

What Can We Anticipate From the Hotcig RDS Double System?

Hotcig was started in 2013, so it’s definitely been around for some time.

The brand name obviously came from the United States, however are based in Shenzhen where it has both the WARM brand name and also Hotcig.

Recalling with the archives it doesn’t resemble we’ve examined a number of their outcome in the past.

As a matter of fact the just one I can discover was Red Beard Vapes’ testimonial of the Kubi Refillable Covering below (looter, he liked it!)

As a matter of fact I have actually never ever made use of a Hotcig item myself, so I’m entering into this a little blind.

This was sent out over from Heavens Present for the testimonial (thanks), customarily this will certainly not influence my testimonial, and also I will report back truthfully on what I discover!

Style and also Construct Quality

The body is constructed from clear PCTG and also is available in among 4 various colours.

I obtained the brownish-yellow variation, and also it additionally is available in Clear (without a doubt the very best searching in my point of view!), Black, and also Purple.

Hotcig RDS Dual System Colourways

The purple one is absolutely an intriguing option!

Something that deserves keeping in mind is that the brownish-yellow one is not in fact constructed from ultem, so it might not pair up with an ultem storage tank.

Hotcig RDS Double System Body

It’s a reasonably high gadget, with an eliminated to display the battery tube on the back.

On one side it has a USB C link that bills at 1A and also can additionally be made use of for firmware updates.

Hotcig RDS Double System Battery Cap

The base of the gadget has your regulative marks, in addition to RDS Created by Hotcig.

It utilizes a screw down battery cap, which is a little crispy and also doesn’t capture the strings really conveniently.

So a small disadvantage for fit and also surface.

On the straight bar of the battery cap, it has an additional remove to represent the truth that this is for the adverse get in touch with of the battery.

There is a favorable indication inside the back of television, however as it’s molded right into the PCTG body, it’s not extremely simple to see.

There are additionally 2 air flow slows down in the body that associate the sheathing when it is put.

Hotcig RDS Double System the RDS Covering

Checking out the sheathing you have a selection of 2 drip pointers that feature the package.

Hotcig RDS Dual System pod

One is a thinner birthed flower holder designed pointer, better to mouth to lung, the various other is a much more stumpy broad birthed pointer, for straight lung.

Hotcig RDS Dual System drip tip options

Naturally if you don’t like either of these, it is a common 510 link so you can change it with your favorite drip pointer.

One minor problem I did have, was that the broad birthed drip pointer rejected to take a seat right into the sheathing effectively.

Due to the fact that just the base of the sheathing beings in the gadget, it is constantly really simple to watch on your e-liquid degree.

This might be a little bit much more tough on the black clear variation (depending upon just how dark it is) however on the brownish-yellow it wasn’t an issue in all.

Hotcig RDS Double System Air Flow Control

Air movement is changed on the gadget by turning the entire of the sheathing, aligning the twin cyclops air flow openings on the sheathing.

Because of the remove it will just suit one means, and also will certainly shut completely open or shut.

If you place the 510 adapter in, the air flow openings are entirely concealed (as they would certainly offer no function).

As well as the adapter (unlike the sheathing) does not revolve in all.

Just How To Fill Up the Hotcig RDS Double System Covering

  • Eliminate the sheathing from the gadget and also situate the red silicone stopper
  • Disconnect the red stopper and also full of your recommended e-liquid, it has a big sufficient fill opening however you ought to still watch out for attempting to load it to rapidly
  • When complete, change the the silicone stopper and also bear in mind to leave it to rest for 5-10 mins to prime

Take care however, I had the red stopper separate totally a number of times, and also it’s a discomfort to obtain it to return in!

Don’t draw as well hard, and also simply carefully bar it up where the arrowhead on it reveals.

Just How To Modification The Hotcig RDS Double System Coil

  • Take out your present coil

Hotcig RDS Double System Display and also Controls

The front of the gadget has an uncommon account, however it creates a remarkably ergonomic gadget.

There’s just one control on this however it takes care of to do every little thing it requires to.

rds controls

It’s an instead intriguing gear formed wheel.

Scrolling clockwise boosts your power level in 1W increments, from 1W to 100W, scrolling anticlockwise will certainly lower it.

It does not rounded robin, so it’s fairly a great deal of transforming you need to do to go from one extreme to the various other.

Nonetheless I believe this makes many feeling, as if you’re utilizing it near it’s minimal power level, you would certainly not wish to unintentionally knock the wheel and also have it rounded robin as much as 100W!

One more adverse niggle from me is that the control wheel on my instance is inclined away a little bit.

It definitely doesn’t appear willful, as it’s practically as though the entire wheel as been affixed lop sided. Depending upon where it gets on it’s turning it will certainly be either essentially obvious.

Hotcig RDS Dual System wonky control wheel

With any luck this is simply my one, however once more it doesn’t talk to the very best quality assurance. I truly like the control wheel as an idea, and also I’m glad it’s constructed from steel as I believed it might be plastic when I initially saw pictures.

You can additionally click it in to make options, and also it is your fire switch in addition to this.

  • 5x Clicks – On/Off
  • 2x Clicks – Lock/Unlock Power level Modification (can still terminate)
  • 3x Clicks – Food Selection

The small display is resting right at the base of the front, and also there’s a void of empty plastic in between it and also the control wheel.

Nonetheless this makes a practical area to relax your thumb when you’re not shooting it.

front view with pod and screen on

Among one of the most smart techniques of this gadget is it’s capacity to recognize whether you have actually put the sheathing or the 510 adapter, and also the display will certainly present a couple of displays revealing either Covering or Mod.

With the sheathing in position the power level will certainly be restricted to the optimum that the coil in operation is suggested for. Clicking right into the food selection you just have the alternative to transform the colour of the display screen.

rds screen themes

Conversely you can click Mod, and also change it right into the various other setting to gain back complete control and also neglect the power level limitation.

If you put the 510 adapter right into the gadget it will certainly change right into Mod setting. This makes a minor distinction to the display screen.

pod vs mod screens

Nonetheless the major distinction is that if you click right into food selection you have the alternative of all the numerous settings

  • Power (variable power level)
  • Variable Voltage
  • Bypass
  • Temperature (with a submenu offering Ni, Ti, SS and also TCR)
  • Modification Show Colour
  • Covering Setting

510 Adapter

The 510 adapter is a relatively standard little package, as you would certainly anticipate it has a springtime placed 510 adapter on top, and also it will certainly occupy to a 25mm storage tank prior to it begins to overhand.

 510 adapter

On the reduced fifty percent it has an instead huge item of steel which includes an encouraging weight to it, in addition to working as your battery calls and also magnet.

Just How Does the Hotcig RDS Double System Perform?

So I’ve done a reasonable little screening over the previous couple of weeks, both with both coils that suit the sheathing, as well as additionally the 510 adapter.

For the 0.3Ω coil I made use of Ohm Kid’s Apple, Elderflower and also Yard Mint at 70/30. I additionally utilized this for the 1.2 Ωcoil, prior to trying some Vape Simple Berry Ice at 50/50.

0.3Ω Coil – Air Flow and also Cloud Manufacturing

Although it’s provided as a 0.3Ω coil, the gadget registered it as being a 0.45Ω

Air movement is fairly a limited DL make use of this coil. On a 1-10 range from limited to broad open, it starts around a 6.5.

Closing it down completely you still obtain a suitable quantity of air coming with, such that it can still do a loosened MTL. On the 1-10 range it closes to a 4.

Something that’s worth keeping in mind is that just like a great deal storage tanks that have plastic AFC, storage tanks and also drip pointers, it is fairly a loud sheathing on the inhale, there’s a great deal of “whooshing”.

Cloud manufacturing is quite satisfactory, however this coil definitely isn’t targeted at cloud chuckers!

0.3Ω Coil – Flavour

Flavour it respectable from this coil, it’s definitely dealt with all the e-liquids I’ve tossed at it.

Offered you remain within the suggested power level (which you are secured right into unless you change to mod setting) after that I’m really happy with the flavour outcome.

1.2Ω Coil – Air Flow and also Cloud Manufacturing

This coil reviewed as a 1.4Ω on the gadget.

This is a far more limiting coil (as you would certainly anticipate). With a thinner birthed, also broad open you are mosting likely to have a hard time to obtain a straight lung draw.

At it’s largest, it’s 4 on the 1-10 range. Closing it down and also it makes relatively little distinction, also entirely shut it’s about a 3 on the range.

Being a much greater resistance coil, it additionally creates a great deal much less vapour.

1.2Ω Coil – Flavour

Flavour is okay in all for a mouth to lung coil. It can take care of 70/30 e-liquid without trouble, however it absolutely executes at it’s ideal with a thinner fluid like a 50/50

Flavours are clear throughout the power level array, however there wasn’t much of a throat hit.

It additionally wasn’t as excellent as the flavour from the 0.3Ω coil. As a matter of fact for mouth to lung usage, I in fact wound up liking that coil with the air flow closed completely down.

Hotcig RDS Double System As A Mod

I did a little bit of screening utilizing this as a pure 80W solitary battery mod, and also whilst it really feels quite simple to make use of, the dimension of the coil appears means off.

By contrasting the very same storage tank and also coil on the RDS Double system, to a DNA mod as well as additionally my ohmmeter, I saw fairly a substantial distinction.

510 adapter and a 22mm tank

I usually run in between a 0.5Ω and also a 0.8Ω coil depending upon the storage tank for mouth to lung.

The Hotcig RDS Double System would constantly review it as concerning 0.2Ω more than the real resistance. I’m uncertain precisely what is creating this, and also I initially believed that the 510 adapter might be the wrongdoer.

However I was additionally obtaining a little greater analyses than I anticipated on the supply coils, so it might simply be that chipset itself is overstating the resistance.

Currently clearly it is completely useful when the mod reads the incorrect resistance (specifically if you change to variable voltage). However it doesn’t load me with self-confidence, and also apart from the screening that I did, it’s not something that I would certainly proceed utilizing this way.


I believed I was mosting likely to have the ability to do my typical examination of the battery life by watching on the smoke counter.

Nonetheless, I wound up taking the battery out a number of times throughout screening, and also it was just later on that I became aware that this resets the smoke counter!

Having stated that, it did appear to carry out in addition to I would certainly anticipate most solitary battery 18650 mods to carry out. Definitely I faced not a problem!


  • Creative changing from Covering to Mod
  • Features a 510 adapter
  • Control wheel functions truly well


  • 510 adapter reviews resistance expensive
  • Drip pointer doesn’t fit effectively
  • Control wheel leans over away
  • Battery door is grindy

Last Testimonial Decision

It’s an intriguing take on the sheathing mod, and also the control wheel is in fact among my favorite user interfaces.

I like it on a Dual Barrel, and also Hotcig have actually done a qualified task of developing one below. It’s simply a pity mine gets on the wonk!

As a matter of fact there were a great deal to times when assessing this item where I had a first favorable impact, just to be pull down by the fit and also surface of it.

I such as screw down battery doors, however this is grindy and also doesn’t capture well.

It’s excellent to have a choice of a number of drip pointers, however one doesn’t rest effectively.

Actually smart to have the gadget button from sheathing to mod setting when you connect the 510 adapter, however it’s resistance analysis is escape

Simply put I truly wished to like this gadget, the control technique is intriguing and also functions well, it has some smart dress up it’s sleeve, and also it really feels comfy and also light-weight in the hand.

It’s simply not quite possibly created.

It deserves keeping in mind that every one of my objections have absolutely nothing to do with the layout of the system itself, so there is an opportunity that I was simply truly, truly unfortunate and also I obtained a duff one with great deals of little imperfections.

Nonetheless if that’s true, after that it doesn’t talk to their being a fantastic quantity of quality assurance either!
