Early Bird Compass Boro Tank – £11.99
The Early Bird Compass Boro Tank is a standalone boro tank designed for vapers who build their own setups. This moulded PCTG boro tank ships empty, allowing you to install your own RBA bridge and customise your vaping experience with any e-liquid ratio your coil configuration supports. It’s an excellent choice for experienced builders seeking a compact, colourful tank that pairs seamlessly with boro mods and billet box style AIOs.
The Compass stands out for its innovative front-facing borosilicate glass sliding door—a rare feature in mass-produced boro tanks—giving you a clear, unobstructed view of your wick saturation and liquid level at all times. Construction uses lightweight, durable moulded PCTG with magnetic swappable bases that let you mix and match colours between tanks without any threading or tools required. Side fill via a rear rubber plug ensures mess-free refilling without removing the tank from your mod. Available in eight vibrant colours—amber, smoked, clear, blue, red, toxic green, pink, and purple—the Compass offers genuine customisation options to match or contrast with your setup. The tank fits standard boro tank dimensions and accepts any compatible RBA bridge, making it versatile for builders already invested in RDA and RBA hardware. Pair with your choice of shortfill e-liquids or mix your own.

How It Compares
The Compass differs fundamentally from conventional sub-ohm tanks and prefilled pod systems. Unlike mass-produced boro tanks, it features a sliding borosilicate glass front door rather than a traditional transparent tank body, providing superior wicking visibility and a distinctive aesthetic. The magnetic base system—absent from most competitors—eliminates threading and allows genuine cross-tank colour customisation without tools. As a standalone tank requiring your own RBA bridge, it suits experienced builders rather than beginners; it offers complete flexibility in coil configuration and e-liquid ratio, unlike fixed-coil sub-ohm tanks or sealed pod kits. Its compact boro footprint makes it lighter and more portable than larger billet box mods, yet it retains the aesthetic and build customisation that appeal to hobbyist vapers. The eight-colour range provides genuine visual variety, setting it apart from the limited colourways typical of mainstream vape tanks.
Frequently Asked Questions
What’s included in the box?
The Early Bird Compass Boro Tank ships with just the tank itself. The RBA bridge is not included, so you’ll need to source a compatible standard boro RBA bridge separately. This allows you to choose or reuse a bridge that suits your building preferences.
How does the Compass compare to a traditional sub-ohm tank?
The Compass is a boro tank designed for experienced builders, not a pre-built sub-ohm system. Sub-ohm tanks come with fixed coils and are sealed; the Compass ships empty and accepts your own RBA bridge, giving you complete control over coil design, winding, and e-liquid ratio. Sub-ohm tanks suit convenience seekers; the Compass suits hobbyists who enjoy building and customising.
Can I swap colours between my Compass tanks?
Yes. The magnetic swappable base system lets you mix and match colours between multiple Compass tanks without any threading or tools. If you own several tanks in different colours, you can combine bases and bodies to create new colour combinations.
What e-liquids work with the Compass?
The Compass pairs with any e-liquid ratio your RBA bridge and coil configuration can handle. Many builders use high-VG shortfills for cloud production or balanced 50/50 ratios for flavour-focused builds. You can also mix your own using DIY supplies. The tank itself has no liquid restrictions—only your coil’s wicking capacity matters.
Is the sliding glass door durable?
The front door is borosilicate glass, which is heat-resistant and durable. The sliding mechanism is designed for frequent opening and closing. However, like all glass, it can crack if dropped or subjected to heavy impact. Treat it with care, and it will provide reliable visibility for your builds.
