SBS Mod Guide 2026 - What Is a Side-by-Side Vape Mod
What Is an SBS Mod?
SBS stands for Side-by-Side. An SBS mod is a type of vape mod where the battery sits beside the atomizer rather than underneath it. This side-by-side layout makes the entire setup significantly shorter and more pocket-friendly than a traditional tube or box mod, while still accommodating standard 510 atomizers.
Imagine a traditional box mod: the atomizer sits on top, the battery below, creating a tall "T" shape. An SBS mod folds this layout horizontally -- the atomizer and battery sit parallel. The result is a compact, almost square-shaped device that fits comfortably in a palm or pocket without the atomizer sticking out like a tall antenna.
SBS mods bridge the gap between boro-style AIO devices and full-sized traditional mods. They offer the compactness of an AIO with the flexibility of using any standard 510 atomizer.
Why Choose an SBS Mod?
- Compact and pocket-friendly -- The side-by-side layout drastically reduces height. An SBS with a 22mm RTA is often shorter than a pod system with its drip tip.
- Atomizer versatility -- Unlike AIO or boro devices that require specific tanks, SBS mods use standard 510 connections. You can use any RTA, RDA, RDTA, or tank atomizer.
- Battery options -- Most SBS mods accept 18350, 18500, or 18650 batteries (some even 21700), giving you flexibility between size and battery life.
- Stable center of gravity -- Because the atomizer sits beside the battery rather than on top, an SBS mod is much less likely to tip over on a desk.
- Less lever force on the 510 connector -- In a traditional tube mech mod, the atomizer acts as a lever, putting stress on the 510 threads. In an SBS, the atomizer and battery share the same horizontal plane, reducing mechanical stress.

| Width | Medium (45-55mm) | Narrow (25-35mm) | Narrow (25-35mm) |
| Atomizer compatibility | Any 510 atomizer | Any 510 atomizer | Boro tanks only (bridges/RBAs) |
| Battery | Single 18350-21700 | Single or dual 18650/21700 | Single 18650 or internal |
| Max atomizer diameter | 22-24mm typical | 25-28mm+ | Boro-specific |
| Pocket-friendly | Excellent | Poor (tall) | Excellent |
| Customization | High (change atomizers freely) | Very high | Moderate (boro ecosystem) |
| Best for | MTL vapers, EDC, travel | Cloud chasers, DL vapers | Boro enthusiasts, tinkerers |
Types of SBS Mods
1. Mechanical SBS Mods
Unregulated SBS mods with no electronics -- the battery connects directly to the atomizer when you press the fire button. These are simpler, more durable (no chip to fail), and preferred by purists. They require battery safety knowledge and familiarity with Ohm's Law. The Timesvape Sidekick is a popular mechanical SBS that accepts 20700/21700 batteries for extended battery life.
2. Regulated SBS Mods
Feature a chipset (typically DNA60, DNA60C, or proprietary) that provides variable wattage, temperature control, and safety protections. These are safer for beginners and allow you to fine-tune your vaping experience. Regulated SBS mods like the SENSIYU Noble SBS offer a compact 18350/18650 platform with full regulation, perfect for MTL vaping.
3. Boro SBS Mods
A hybrid category: an SBS body designed specifically for boro tanks. These combine the side-by-side layout with the boro tank ecosystem, allowing you to use bridges and RBAs while keeping the ultra-compact SBS form. The AOP Style DNA60C Boro SBS is a prime example -- a DNA60C-powered SBS designed for boro tanks with an embedded 18650 battery.
How to Choose Your SBS Mod
1. Regulated vs Mechanical
If you are new to rebuildable atomizers, choose a regulated SBS for safety. The chipset protects against short circuits, low resistance, and low battery voltage. Mechanical SBS mods are for experienced vapers who understand Ohm's Law and battery safety.
2. Battery Size
- 18350 -- Smallest form factor. ~700-900mAh. Good for half-day light MTL use.
- 18650 -- Most common. ~2500-3000mAh. Full day of MTL vaping.
- 20700/21700 -- Largest. ~4000-5000mAh. Best for extended use or DL vaping.
The SENSIYU Noble SBS supports both 18350 and 18650 batteries with included adapters, giving you flexibility to choose between ultra-compact or longer battery life.
3. Atomizer Compatibility
Most SBS mods support up to 22-24mm atomizers. If you plan to use larger RDAs or tanks, check the maximum atomizer diameter. MTL RTAs (typically 22mm) pair perfectly with SBS mods.
4. Material and Build Quality
SBS mods come in various materials: POM (lightweight, durable), PEEK (high-temperature resistant), brass/copper (heavy, conductive), stainless steel, and 3D-printed nylon. The SENSIYU Noble in PEEK offers excellent heat resistance and a premium feel.

Frequently Asked Questions
What does SBS stand for in vaping?
SBS stands for Side-by-Side. It describes the layout where the battery and atomizer sit beside each other rather than stacked vertically.
Can I use any RTA on an SBS mod?
Most SBS mods support 22-24mm atomizers. Always check the maximum atomizer diameter specified by the manufacturer. 22mm MTL RTAs are the most common pairing for SBS mods.
Are SBS mods good for beginners?
Regulated SBS mods are suitable for beginners who already have some rebuildable atomizer experience. However, if you are completely new to vaping, a pod system or AIO device is a better starting point. SBS mods are ideal as a second or third device upgrade.
Can I use an SBS mod for DL (Direct-to-Lung) vaping?
Yes, if the SBS mod uses a 21700 battery and supports enough power output. Mechanical SBS mods with 21700 batteries (like the Timesvape Sidekick) can handle DL builds. However, the 22-24mm atomizer size limit may restrict your choice of DL tanks.
What is the difference between SBS and Boro mods?
An SBS mod uses standard 510 atomizers (any RTA/RDA). A boro mod uses proprietary boro tanks with bridges and RBAs. Boro SBS mods (like the AOP DNA60C Boro SBS) combine both: an SBS body with a boro tank compartment.
How do I maintain an SBS mod?
Clean the 510 connection regularly with a cotton swab and isopropyl alcohol. For mechanical SBS mods, polish the contact points periodically to maintain conductivity. Store with the battery removed if not using for extended periods.
Final Tips for SBS Mod Buyers
- Pair with a short 22mm MTL RTA -- The classic SBS setup. A short atomizer like a By-Ka SE or Monarchy OST keeps the overall height minimal and looks proportional.
- Consider 18350 for ultimate compactness -- If you MTL at 12-18W, an 18350 battery lasts half a day and makes the SBS incredibly small.
- Check the 510 pin protrusion -- Some hybrid-style SBS mods require atomizers with a protruding 510 pin. Always verify compatibility before use.
- Buy a spare battery set -- Single-battery SBS mods benefit from having a charged spare ready to swap in. Browse our full mod collection for more options.
