Lost Vape Grus 100w mod

Many thanks to Lilia @Sourcemore for sending this for review. These are my opinions & have no affiliation to Sourcemore or Lost Vape.

After a bit of a lean spell Lost Vape have been creating some nice mods lately & the Grus is one of the latest additions to the stable. Read on to see how I got on with it.

Package is a sleeved outer depicting the colour/style of the mod on the front & contents list & usual warnings on the rear. Remove the sleeve & the lid of the main box & you have the mod, wrapped in an HDPE sleeve, sitting in a foam tray underneath which is the manual. Unbagging the mod & removing the battery cap reveals the 18650 adaptor & USB C charging cable stowed inside. The supplied model is the Black frame with wooden inlays & SS 510 & base. Other colours are available.

In the hand

This is not a lightweight mod even without a battery. Using quality materials this gives an air of higher end mod without the price tag. Paint finish has, so far, showed no signs of chipping or scratching and the top is a substantial 30mm with a sprung 510 pin. On the base is a screw on battery cap, with a lift up catch to make fitting and removal easy. The battery tube isn’t marked for polarity, save for a + embossed into the contact at the top of the tube. Three vent holes are drilled into the battery cap, although the battery is fitted positive up. The “wooden” inserts on the sides appear not to be stickers/vinyl as they don’t take an impression if you push a fingernail in.

On the front face is a fire button, 0.96” TFT colour screen and three navigation/menu buttons with the USB C socket completing the finish. The button/screen surround is a gloss finish with the rest of the body being matt black and gives protection to the inset screen. The screen is clear and bright, and the important info is easy to read. At the top is a battery meter graphic & coil resistance. Underneath is the Mode, then Power/Temp. Below the chevron is the Puff timer & counter and right at the bottom is a row of coloured dots relating to the optional colour schemes available. The watts increments by 0.1 on single clicks and 1w when held. The watts round robin back to 5w when the 100w limit is reached. The temperature can show either Celsius or Fahrenheit by scrolling through to min/max and pressing again to change.

In use

All testing was done with a 21700 battery to try to maximise run time. Once installed, a standard 5 clicks turns the mod on/off. Anybody who has used a DNA C boarded mod will immediately recognise the 3 button layout & like those boards the top/bottom buttons are used for increasing/decreasing settings. The middle button, when pressed will highlight the mode in red and up/down button will scroll through the Power, SS316, Ti, Ni and Voltage. Pressing the centre button locks the selection.

Given the similarity to a DNA C device it seemed logical to try out the temp control first. A dual SS316L coil set up at around 0.3ohm seemed a good place to start. Selecting the SS316 profile and a temp of 240c started well. One thing to note though, there is no way to set the output power only temp. The temp control worked well & prevented a dry hit even when chain vaping. Without wattage adjustment it was impossible to fine tune and it felt somewhat under powered. Power mode worked equally well with output consistent and quick firing with single coil or mesh but seemed under powered with dual coils. Voltage mode worked equally well for those who prefer using volts over watts.


The Lost Vape Grus is a very capable, well built mod that delivers decent performance at a very reasonable price. The big 30mm 510 plate allows bigger tanks to be used but 24mm and smaller RTA/RDAs can look a little lost. The only other thing that let it down was battery life. I compared the run time with a 21700 DNA75C and sadly this lagged behind with the same 0.3 SS dual coil build in both power and Temp mode. At the same wattage it also felt weaker compared to the DNA mod. Most likely cause is an apparent lack of boost/preheat. TC mode did give better runtime as it won’t be outputting constant power, instead dropping to control the temperature.

There’s no battery rattle, thanks to the screw in cap, on either 21/20700 or 18650 with the adaptor. Although not recommended, on board charging is possible via the USB C port & peaked around 1.4 Amp, although there is no pass through available. Battery cut off averaged 3.3v.

Currently it is available at Sourcemore and there’s a discount code LVG making the LV Grus $26.99 Lost Vape Grus 100W Mod . Thanks again to Lilia at Sourcemore.


Nice Review.
Running mine with The Samsung 30T and Steam Crave Aromamizer V2 with dual core Claptons read at .18ohm and wicked with Rayon. Good little piece! performs well. Im wondering if there were a memory limitation preventing the ability to dial in the wattage adjustment in TC. Thats the only minor objection I have to it.
Is it as punchy as my Paranormal 250C? No(boost settings/preheat settings and a more elaborate chipset. Will I keep it in my daily rotation? Hell yes! Love the ability to charge from USB-C if needed.
At the price point it is a great option for anyone to consider.


Thanks bud, much appreciated.
To be honest I’m a little disappointed. A DNA75C outperformed it on battery life & that shouldn’t happen. The 75C is a custom job & the wiring is to or above spec. It’s a well built mod but do think that board lets it down. The Ursa uses an updated Quest board & apparently it’s better so hopefully there’s a firmware upgrade.


I would guess that the DNA75C’s efficiency and the wiring you used in your custom build are the reasons for that. Yes a firmware upgrade adding the wattage feature on TC would be ideal. Lostvape must have had their reasons for not including it, and Im suspecting size of code might have been their reason. Above my paygrade, though. lol


Awesome review brother :ok_hand: :wink: nice job :+1:


Thanks bro, much appreciated. And congrats again, don’t be tripping over your halo though :rofl: :rofl:
