The BTB kit is a box mod and tank kit that has just been released by Lost Vape. BTB stands for “Back to Basics”, and it’s an appropriate name for this kit because it’s relatively simple and offers a no-frills vaping experience.
The BTB is a single 18650 battery mod that can fire up to 100W. It comes with the Ultra Boost X tank which has a 4ml max capacity, and it takes the same UB coils as the recently released Lost Vape Gemini Hybrid that I just reviewed.
The BTB Kit comes with two coils, but I also have two other UB coils and the RBA on hand for testing. I’m gonna go through them all and let you know how this kit performs.
A big thank you to Lost Vape for sending me over the BTB Kit for review.

Design & Build Quality
The BTB is a slim and tall mod. It’s 91mm tall, 36mm wide, and 25mm thick which is a good size for a single battery mod. It’s made of zinc alloy so while it is sturdy, it’s also heavier than you would expect for the size. Still, I don’t think that it’s so heavy to the point where it’s inconvenient to bring around, it just has some weight to it.
There are seven color options available for the BTB: Red Camo, Blue Camo, Green Camo, Black Camo, SS Vintage Camo, Black Vintage Camo, and Matt Black Vintage Stars. Personally, I love how the Matt Black Vintage Stars looks, but the SS Vintage Classic that I received is almost just as nice. The paint is a satin finish that looks good.
The panels are finished with what feels like canvas and painted over smooth. This is different from other devices that tend to use plastic or resin panels so it’s a nice change. The canvas feels nice and rubberized to the touch and it appears to be high quality work. On one side the panel has BTB printed. On the other panel Lost Vape is printed.
The screen is 0.96” and full color. It’s the exact same UI as the Gemini Hybrid and I rather like it. It’s bright and clear and displays a host of vaping information.
There are four buttons on the BTB: a fire/power button, two adjustment buttons, and a mode button. The buttons are made of plastic but they feel good nonetheless. They’re all clicky and firm, but still easy to press and nice to use.
The 510 plate is small, but the mod is only 25mm thick so you can’t expect it to hold large atomizers.
The battery door is an issue on the BTB. The notch to remove the panel is so small that it’s difficult to get to, even with nails. I can only imagine trying to remove it without nails. Once the panel is off, the battery compartment is what you would expect. It’s not too tight and fits an 18650 battery snugly.
Features & Functions
The BTB uses the same UI as Lost Vape’s Gemini Hybrid, but it has a few extra modes that the Gemini Hybrid doesn’t. The BTB has power mode, voltage mode, and TC modes for Nickel, Titanium, and SS316. It has a maximum output of 100W.
The screen displays a battery life indicator, your coil resistance, your wattage, puff time, and a puff counter.
Seeing as this is the Back to Basics kit, the button combinations are simple:
- Power on or off: click the fire button five times
- Change mode: press the mode button, then use the adjustment buttons to cycle through the modes.
- Lock the adjustment buttons (device will still fire): hold the + adjustment button and mode button together until the screen displays “LOCKED”. To unlock the device, do this again.
- Clear the puff counter: hold the mode button and – adjustment button.
- Change UI color: Hold the mode button.
Ultra Boost X Tank
The Ultra Boost X Tank is a good looking tank. The color of the tank matches the color of the kit and they look good paired together. The Ultra Boost X tank has large ridges for design and grip on the airflow control ring. These ridges remind me of the bottle cap appearance on the Blotto RTA.
The UBX tank is top filled and the top cap pushes back to reveal the fill port. The top cap is easy to push back and this concerns me a little. It feels a bit too easy to open. The fill port is lined with a silicone gasket and easy to access and fill. It’s recessed a little under the top cap to make the chances of leaking minimal.
You get two drip tips in the box, one for MTL and one for DTL. The airflow further gives you the option of MTL or DL by having both slots and holes for airflow. If you want a DL draw you can set the airflow to the slot, while for a MTL experience it can be set to the small holes.
The UBX uses the same Ultra Boost coils as the Gemini Hybrid. These coils push into the bottom of the tank for easy, no-fuss installation. No need to fiddle about with threading the coils in. The UBX Tank comes with a 0.2ohm DL coil and a 1.0ohm MTL coil.
The RBA coil is sold separately but it’s worth the purchase. The coil has a small, two post build deck that requires your coil legs to be facing the same direction. There’s an airflow hole on the bottom of the deck that funnels airflow up and through the coil.
The RBA package includes two simple, round wire coils and cotton. There are also replacement hex screws. The hex screws on the deck are good and grip the coil legs firmly. I installed my coil so that it lined up with the wicking ports on the side of the deck. I tried installing it first positioned over the airflow hole but this made wicking much more difficult.
Once the coil is in and secured, I cut my legs. This deck doesn’t require you to pre-measure the coil legs so it’s really easy to build on. There’s a 510 adapter in the package that you can use to dry fire the coil and check for hot spots. My coil glowed evenly but if yours doesn’t, strum the coil with a pair of ceramic tweezers to work out the hot spots.
With the coil ready, I threaded through a small sliver of the included cotton. You want the cotton to be tight, but not so tight that it misshapes the coil. Your wicks have to be cut very short in order for the RBA cap to screw on; I found just above the base of the wicking ports to be perfect. Make sure to comb out your cotton a little, too.
Screw on the RBA head and push the coil into the tank and you’re done.
The coils for the BTB kit are the same coils as for the Gemini Hybrid. However, I felt like these coils performed better in the UBX Tank than they did in the Gemini Hybrid. This is likely due to the shape of the tank and chimney.
The airflow on the UBX tank is great because it lets you DL or MTL any of the coils due to the slot and hole airflow setup. For a DL draw, use the slot airflow. If you prefer a tighter MTL draw, set it to the hole airflow and you’re set.
This coil is rated for 4-60W and it performs best at the higher end of the wattage range. Flavor at 40W is okay, but the coil feels underpowered. Moving the wattage up to 50W gets better and the flavor starts coming through. At 60W is the sweet spot for this coil and the flavor and clouds are good. This coil was a great DL vape but delivered muted flavor and vapor that was too hot when I tried to MTL vape it.
This coil is rated for 8-15W and is a MTL coil. I used the MTL drip tip on the UBX tank when I vaped this coil and the results are decent. 8W doesn’t do much for this coil, with barely any flavor or vapor coming through. I jumped straight to 15W and got okay results. The airflow set to the two holes gives a tight MTL draw and the flavor is decent. This coil is better than in the Gemini Hybrid, but not by much. It’s still an average MTL coil, even in the UBX tank.
The coil that comes with the RBA came out to 0.48ohm. Where the Gemini Hybrid doesn’t let you adjust the airflow with the RBA, the UBX Tank does. The draw with the airflow open is an airy DL draw with no restriction, which changes to a MTL draw when you close off the airflow. Flavor from the RBA is noticeably better than either of the stock coils. Vaping at 30W is really nice with this coil and the vapor is smooth and warm. Very enjoyable to vape on!
This coil is not included with the kit and is sold separately. It’s rated for 20-28W and can function as either a DL or MTL coil depending on how you set the airflow on the UBX Tank. Flavor from this coil is good and makes my ejuices pop. It’s best at 25-30W with warm and pleasant vapor that makes it very enjoyable to vape on.
Last but not least, the 0.3ohm coil. This coil is rated for 30-40W. This coil is similar in performance to the 0.6ohm coil, only it works at a higher wattage. It can be used for DL or MTL depending on how you set the airflow, but at 40W it’s best used for DL. Flavor is good and the clouds are impressive, too.
The BTB starter kit is a decent little kit. The coils performed better in the UBX Tank than they did in the Gemini Hybrid and that’s a welcome change.
I like that you have a variety of options for coils and for the type of draw that you like, with some coils being able to go either DL or MTL. My breakdown of the coils is as follows: MTL coils are the 1.0ohm and 0.6ohm coil. DL coils are the 0.2ohm coil, 0.3ohm coil, and 0.6ohm coil. You also have the option of the RBA that can go either way.
Operating and vaping with the BTB kit is simple and will appeal to beginner vapers, but advanced vapers will also find it nice because of the coil and airflow options and ease of use.
