This time I’m going to be looking at the newly released Geekvape Obelisk 120 FC box mod.

This device has two internal lipo batteries and will fire at 120w, and has the capability of fast charging!

Founded in 2015 GeekVape is based in China, and has a great name for innovation within the vape industry.

Geekvape has a large back catalogue of products which include the Aegis range of mods, and tanks like the Zeus X RTA, Zeus X Mesh RTA, Zeus sub ohm tank, and their new tank the Z Max Tank

What Can We Expect From the Geekvape Obelisk 120 FC?

I’ve got to say I love the attention to detail that Geekvape give its products, I love my Geekvape Aegis Legend I always included it within my daily rotation!

So when I was asked to review the Geekvape Obelisk 120 FC mod, I literally jumped at the chance!

The Obelisk 120 FC mod has shiny side panels almost mirror like in a way, it has two internal lipo batteries that total 3700mAh, the device can be used for OTG reverse charging.

Its menu system is intuitive and easy to understand, the device has a USB type C charge port, all this and a full colour TFT screen as well!

Geekvape has produced the device in 4 distinctive colours – Silver, Black, Blue and Gunmetal.

As always my thoughts and views are my own after a considerable testing period.

I received the mod only kit!

The Geekvape Obelisk 120 FC mod come presented in a cardboard box with a paper over sleeve, the only other thing to be included in my kit was a double ended USB C charging cable – oh and the usual paper work.

I was sent the silver coloured version of the mod.

Standing at 80mm tall with a tank diameter of 25mm and a width of 45mm the Obelisk 120 chassis is constructed of Zinc-Alloy with almost mirror like side panels.

The GeekVape Obelisk 120 Body

Sadly Geekvape has moved away from the indestructible, waterproof, dust-proof and shock-proof design of the Aegis line, making this device look totally different from what we are used to seeing from the company – they say that the innovation is on the inside this time!

Geekvape Obelisk 120 FC like a mirror sort of

The body has chamfered edging and the back has 2 lines milled for decoration, the device is comfortable to hold in the hand.

The clean straight lines give an interesting fresh look to the device.

On looking at the top of the mod you will note it is flat and that the connection is slightly off centre.

The 810 connection has been recessed in to the body with a gold plated spring loaded connection pin and well turned threading, whatever topper you put on the device will sit nice and flush.

The bottom of the mod has all the relevant information printed, however with this silver version the info is quite faint to read!

Out of the box the Obelisk comes with some charge to it, the TFT screen is colour and measures in at 0.96in.

The mod has the normal fire and adjustment buttons which are made of a plastic material.

The GeekVape Obelisk 120 Sides

The side panels have a mirror like quality to them, if moved in the light you can see a swirl pattern in them – “I feel they could be scratch prone” they are also big finger print magnets!

On the right side to the screen is the USB C charge port.Geekvape Obelisk 120 FC close usb c port

For advertising the panels both sides have the word “Geekvape” printed on them.

GeekVape Obelisk 120 FC Kit Options

While I was sent the mod only version, Geekvape have released the kit in several different versions, i.e. with or without the charger all other kits include a rather nice looking tank the Obelisk Z Tank.

Charging the Geekvape Obelisk 120

This is really strange while the kit comes with a double ended USB C charging cable!

I don’t have a USB C adaptor so I had to source a USB to USB C cable from elsewhere LOL.

Be aware – while advertised on the box as a fast 15 minute charge! Without the charge kit the mod will not charge at the fast rate! But will charge on USB 2.

How Does the Geekvape Obelisk 120 FC Perform?

For this review I will be using the mod with my Vapefly Core RTA with my own DIY dual Kanthal Fused Clapton coils, which work out to around 0.13Ω!

I will be using Kwik Vape “Wild Cherry” a locally produced E-Liquid to me, see what I thought of it at the end of this review.

Basic Operation Of the GeekVape Obelisk 120!

The GeekVape Obelisk 120 has a very familiar menu system, if you have used one of the Aegis mods you will find this menu system very easy to navigate.

  • To turn the device on or off hit the fire button X5 fast.
  • X3 presses of the fire button allows you to change the operating mode from Power to TC SS, TC TCR, VPC, BYPASS as well as activating the OTG reverse charge.OTG screen
  • To change the theme colour press the adjustment buttons together while in the X3 mode.
  • While in TC mode you can scroll through to lock your resistance as well as change the TCR values and Puff count.
  • To alter any adjustments use the + or – buttons.
  • Pressing + and – together locks the adjustment function, the mod will still fire.
  • By pressing the fire button with either adjustment button you will be able to change the brightness of the screen.

To be frightfully honest, while I like the mod and it functions very well, at this time I cannot test the kit to its full potential without the charge kit!

The device looks great and works well with all of the menu settings!

tank and mod liquid

But one of my biggest complaints is the battery case is it’s a real finger print magnet, which sets off my OCD so I am constantly wiping the mod with a cloth!

prints of fingers on sides

Using these 0.13Ω dual coils in my Core RTA at 60w, I can get around 5 hours vape time!

Of course I have tested the mod with several other toppers such as the Innokin Aries 2 RTA at 20w with very good results, I get over 2 days vape time!

However I found with one of my favourite tanks the VooPoo Maat tank even at 75w it lacked the normal oomph I get with other devices, as one might expect the vape time is reduced at higher wattage.

My experience charging the mod

I guess my biggest disappointment with the kit is the double ended USB C charge cable, I can’t understand why Geekvape have not included a standard USB to USB C cable in the box?

The charge time was stupidly long with USB 2! In fact I thought it had just stopped after 2 hours, it took another 2 hours to complete charging!

On the back of the box Geekvape state that this is a fast charging 15 minute device – what they have left out is the Obelisk 120 will only charge at the faster rate with the optional charge kit!

Power Bank option (OTG)

I can confirm that the OTG power bank option works well with my mobile phone charging it to full charge without problem.

A quick word about the e liquid I have been using during this review, KV “Wild Cherry”.

This is a new liquid to me while a very nice fruity flavour I felt it had something missing so I added ½ an ice shot to the bottle, now it reminds me of summers spent as a child drinking ice cold Corona Cherryade in my Grans garden!

Pros

  • Good quality and great looking
  • Very well designed
  • Functions well as a mod and as a power bank
  • Comfortable in the hand
  • Great battery life

Cons

  • Finger print magnet
  • Not a fast charge mod without charge kit
  • No USB to USB C charge cable in box

Final Review Verdict

I am impressed by the mod as it stands it looks good and functions well, however I can’t get over the fact that Geekvape has not included a standard USB to USB C cable in the box, to me it feels like they are pushing you to spend more to buy the charge kit!

Would I recommend the Geekvape Obelisk 120 FC Mod?

I’m conflicted, on one hand this unit functions well in all modes, on the other the time it takes to charge the mod without the charge kit is silly!

Would I buy this kit again due loss or damage?

Personally “No”, I have however grudgingly spent the extra money and ordered the charge kit!

Hi my name is Kevin, I started vaping back in 2009 mainly because my little boy at 3 years old was starting to copy the way daddy smoked a cigarette! Over the years I have gained a good amount of experience with different types of vaping hardware but I'm just a normal guy who enjoys sharing my experiences. This is why I started my Youtube vape review channel in 2014. To date the channel has had over 500,000 views. Being disabled, vaping has given me a gateway to meeting people from all different walks of life, many of those I would not have met under other circumstances. The way I look at my reviews is, if I can convince just one person to give up the stinky’s my job is done. I class myself as a tinkerer as I like to take things apart to see how they work and put them back together, yes that includes e-cigarette mods! One day I would like to be able to design my own mod. I am a dedicated father, and husband to my sweetheart of nearly 30 years! Family to me comes before anything else.
