The Bohr Chaser Kit likes to do things a little bit different. Controlled with a smart phone chip, and featuring amperage control, lets see how it vapes.

This product has been sent with the kind generosity of BOHR for the purpose of an impartial review. The thoughts that you find below are mine and are no way influenced by the fact that this was gifted.

Available in Silver and Gunmetal

Packaging for the BOHR Chaser Kit is nice, consisting of an inner box and outer sleeve. On the front of the outer sleeve is the BOHR logo, the product name and a silver outlined image of the Chaser Kit. Additionally on the sides we have the usual social media references, the product colour and a QR code for the technical support. Furthermore on the back of the packaging, we have the description of the contents, usual health warnings, and the scratch and check authenticity.

Removing the outer sleeve reveals the inner box, which has a faux leather texture to it and the BOHR logo in silver. Further more, upon opening you are greeted with the Bohr Chaser Mod and a box containing the USB cable and spares. Moreover sat underneath the Bohr Chaser is the Archer tank and the spare straight 6 ml glass.

Build quality

Bohr Chaser Mod

Once in your hands the BOHR Chaser Kit feels comfortable, sturdy and well made. In addition the BOHR Chaser is possibly made out of zinc alloy, sadly there is not documentation for material of the Chaser mod. Furthermore the Chaser has a central 510 which is very nicely milled.

While the 510 plate may have cut outs they are for display purposes only and would be no good for bottom air feed tanks or atomisers.

Alcohol from cleaning is still evaporating and not e-liquid on the silicone washer.

Critically the rubber washer that keeps juice out of the electronics is too big, and has gaps down the sides, this is not good, but more on this later.

Hopefully this is just a one off and the sample I received just has a random naff silicone washer. However it doesn’t serve to promote BOHR’s care towards quality, which elsewhere is in abundance.

The metal battery door is covered in a nice soft rubber coating making it easy on the hands. Moreover it easily pulls off giving access to the battery compartment, where there is an extra metal small pogo connection by the negative terminal. Importantly although easy to remove, the battery door is held in place with good magnets leaving the BOHR Chaser mod without any rattles.

Buttons are responsive with a louder clicking sound on the plus and minus than the fire button. However there is a tiny amount of inward play in the fire button. In spite of this it isn’t too noticeable all of the time, it can just feel slightly weird when you do find it.

Standing at 95.1 mm tall, 28.8 mm wide, and 42.6 mm deep from front to back. However the total height with the Archer mesh tank on is 149.7 mm tall.

It is nice to see a good screen, and the screen on the Bohr Chaser mod is nice, clear and very bright. Indeed the display will have no problem on bright days when it comes to reading the settings.

Bohr Archer Tank

The Archer Tank is well made, and deeply resembles a SMOK TF Tank, this isn’t necessarily a bad thing. But does however make you think of SMOK and not BOHR when you see the Tank.

Featured with a 8 ml bubble glass fitted and a 6 ml straight glass as a spare, there is plenty of juice capacity for its mesh coil. Furthermore the glass tanks sits nicely on the Archer, with no movement or loose glass. However the Archer tank is not a small tank, but does look reasonably good sat on the Chaser Mod. Shame however they didn’t match the finish on the tanks to the mods.

BOHR M1 0.15 Ω Mesh Coil

When it comes to the coils they are nicely made with plenty of cotton pushing against the 0.15Ω mesh coil. In addition there is plenty of air coming through from the bottom and huge juice intakes, so wicking should not be a problem.


Bohr Chaser Mod

Bohr’s Chaser Mod is a single 18650 / 21700 mod and thankfully the Bohr’s long 18650 battery adapter prevents any rattle.

The wrong way to use the 18650 adapter, thankfully Bohr have now changed this on their website.
Correct way of using the 18650 adapter on the BOHR Chaser Mod

A supposed unique element of the Chaser mod is its ability to detect an 18650 or 21700 battery, by means of an extra connector on the negative terminal. Furthermore this helps cut the excess output when using 18650’s, in-turn protecting both the user and the device.

BOHR’s Chaser Mod is powered by the SAGA Player chip that is reported to have been used in the smartphone industry and powers the Chaser mod and its 9 safety protections.

  • Battery reverse protection
  • 10s switch time out protection
  • Over temperature protection
  • Out-put over-current protection
  • Overcharge protection
  • Over-discharge protection
  • Short circuit protection
  • Intelligent battery recognition
  • Intelligent atomiser recognition

Like many vape mods, if you are just using wattage mode, then its super easy to use. However in modes such as temperature control you will need to refer to the manual until you remember it.

Turning on the device is the usual 5 clicks, however to lock / unlock the Bohr Chaser you need to press the fire button and the up button.

In order to cycle through the modes you must press the fire button 3 times in quick succession.


  • Power Mode (Wattage)
  • Play Mode
  • Voltage Mode
  • Temperature Control
  • Custom Mode – Available in W, V, and TC

Using the menu system on the Chaser mod is easy to use. But as you delve deeper in the menu system you will need the manual.

Power Mode

In power mode you are able to set the wattage from 5 W to 80 W with an 18650 and 5 W to 127 W with a 21700 battery.

Access to Custom Mode, Series Number, and Software Version via holding + – buttons simultaneously.


Allowing you to select the amperage output as opposed to setting the wattage or even the voltage. Presumably designed to alter the pulse modulation and up and downing the output to bring out various flavour profiles.

Voltage Mode

Much like wattage mode with the exception that you are setting the voltage output as opposed to the wattage.

TC Mode

Temperature control functions with Stainless Steel (SS), Nickel (Ni), and Titanium (Ti). Furthermore access to Custom Mode, Ω Coil Cooling Value, and Coil Coefficient is via holding + – buttons simultaneously.

  1. From wattage mode press the fire button three times to cycle through modes.
  2. In Temp mode up and down changes temperature
  3. Quickly press fire button four times to reach wattage output
  4. Use up and down buttons to change wattage
  5. Confirm by pressing fire button

Custom Modes

Custom modes are all available in the same section when you enter the custom menu. For example by pressing the fire button three times you can move through custom wattage, custom player mode, custom voltage and custom temperature control.

To change elements such as wattage curve in each custom mode you enter the option by pressing the fire button quickly four times.

Bohr Archer Tank

Designed as a bottom airflow, top refillable stock coil tank. The Bohr Archer is limited with having only one choice when it comes to coils. However it is reported that the SMOK TFV12 coils are compatible. As a result there are a lot more coils to choose from that will work with the BOHR Archer.

The top cap slides backwards revealing the refilling hole, which is a good size for most bottle types, making refilling quick and easy. Revealed when the top cap is open the implementation of a dedicated ventilation hole for refilling is a great idea. Especially as this allows air to escape up through the mouth piece. Thus allowing for faster refilling and no airlock issues slowing down the refilling process.

Importantly there has been no leaking from the tank and the top cap remains in place without a problem and is stiff enough not to move about. Flavour is good, and whilst it may not be the best on the market for a mesh tank, it is up there with some of the higher performers. Furthermore vapour production is also very good for those who like to chuck some decent amount of clouds.

The 18650 adapter used with the Chaser mod can be easily used the wrong way, allowing the higher ranges reserved for 21700 batteries to be accessible. Essentially the method used for the battery detection needs to be improved upon.

Wether that’s a further element that sticks out from the rubber adapter, that then forces it be used in only one direction within the mod. As it stands at the moment, there is going to be someone out there who will use it the wrong way set the wattage to 127 and have a firework display.

From a personal standpoint, Playmode or amperage control tends not to give any more better flavour or performance from that of wattage / power mode and seems pointless. Furthermore I personally would prefer the Amps to be shown on the Wattage mode instead of how long I had just vaped for.


I am actually very impressed with the BOHR Chaser Kit, especially when you remember this is a new company and is there very first mod and tank. Furthermore the flavour from the M1 coil is very good and the mod itself is a solid build. Additionally the M1 coil has great flavour but way overrated, personally the best range was between 45 – 65 watts.

What initially was going to be a very big negative has turned into a major positive for the Chaser Kit. In particular the gap between the 510 silicone washer and the centre pin was initially a possible huge problem. The chances of juice running down into the circuitry appeared to be high.

Bohr Chaser Kit 510 great leakage protection

However this is far from the case, upon removing the 510 plate I was impressed with the amount of protection this had for juice ingress. Furthermore the 510 plate itself has an o-ring that fits very snugly to the mod. Additionally the 510 connection is covered in some form of sealant, that ultimately means there is no chance that the juice can get in. However the lack of detail spent on the o-ring fitting could have easily got the BOHR Chaser Kit a bad review.

BOHR’s Chaser Kit is a great start for BOHR and they should be pleased, yes the mod requires some firmware tweaking and better silicone washers. However as it stands it is not a bad kit and retrospectively there have been companies in the vaping industry for a lot longer, that have made the same mistakes.

BOHR should become a company that we hear more from and are well on the right track with the BOHR Chaser Kit and I for one am looking forward to what they release next.
