Water Bubbler Cart Battery – Smooth Hits Without Coughing!

Water Bubbler Cart Battery - Smooth Hits Without Coughing - Discount Vape Pen

Updated: 25 April 2024

It’s the great conflict for oil cartridge vapers. Cranking your cart battery up to the highest voltage delivers a more potent hit & a thicker cloud of vapor. The drawback? It feels super harsh on your throat. A harsh hit is uncomfortable. It creates a burning feeling at the back of your throat, and leads to coughing – which irritates your throat even further.

So how can you extinguish the flames in your throat?

Simple – Cool the vapor! Water percolation has long been used in water pipes to cool down the temperature of smoke and vapor. Bubbling vapor through water cools the temperature and generates smooth, milky clouds. Water cooling makes vapor more palatable – even for higher strength and harsher delta 8 oils. The drawback of water cooling 510 oil cartridges has been that most cartridge vapers enjoy vaping on-the-go. This hasn’t been possible with a cumbersome water pipe and rig setup. You’re confined to your couch at home.

But our prayers have been answered! The new generation of water bubbler 510 batteries are gifts sent from heaven. They’re small, handheld and 100% portable. You can now enjoy water filtered rips whilst out on the road! Take them with you to work, shopping, or hanging out with your friends. Check these 3 best water bubbler cart batteries, that open up a whole new dimension of vaping;

Hamilton KR1 Bubbler Cart Battery

The KR1 by Hamilton Devices is a revolutionary bubbler cartridge vape. It has 2 chambers. The first chamber houses your 510 cartridge, and fills with vapor when you take a hit. The second chamber is a glass water bubbler. Fill the bubbler with water, and the vapor will bubble up through the water and up the mouthpiece. Both of these 2 chambers are totally transparent, so you can see the magic happen! You can watch as your vapor pours out of the cartridge and bubbles through the water – all whilst illuminated by the color LED light. Hold your thumb over the carb hole, then uncover the carb to take a big hit.

The Hamilton KR1 measures just 2” across. This compact size fits comfortably in the palm of your hand, making it effortless to carry around. The chamber doesn’t hold a huge amount of water (only a fraction of what you’d see on a traditional water pipe). So although it won’t deliver the same experience you’d get from a bong – It still cools your vapor for a nice smooth hit and creamy clouds!

The Hamilton KR1 has another cool trick up its sleeve. As well as oil cartridge compatibility – It also comes with a 510 threaded concentrate atomizer for wax! This dish coil uses ceramic heating to release high quality vapor from your waxy concentrates. The dual-use concentrate compatibility of the KR1 allows you to switch between oil carts and wax. Under the hood there’s a rechargeable 500mAh battery, 3 variable voltage settings. All of this from a high quality brand, and an affordable price tag!

But don’t just take our word for it. Hear what our verified customers think;

“This has turned out to be my favorite 510 Vaporizer, with the bubbler and the battery life, nothing else comes close”
John R, verified buyer

⭐⭐⭐⭐⭐ 5/5
“I use pot for severe pain but do not like carcinogenic since I smoked OS pot recreationally as a younger man. I honestly never thought that I could have this kind of strength again in the form of a vape. I feel like it was a long quest to even find out that this was possible and that Hamilton made this line of products. If you’ve only been using a pen vape, you need to stop right now. Order this. Change your life.”
Uncle R, verified buyer


Hamilton PS1 Double Cartridge Bubbler

Do you like the sound of the Hamilton KR1? Well the Hamilton PS1 is the bigger brother. This water bubbler cart battery takes it up a notch. It has dual 510 compatibility. That means you can vape TWO oil cartridges or TWO wax atomizers – at the same time! It is a high performer in our range of multiple cartridge vape batteries. The Hamilton PS1 packs a serious punch, creating rich and potent vapor. Any harshness is counterbalanced by the water cooling bubbler, to deliver smooth and perfectly enjoyable hits.

The water bubbler function is even more valuable in this dual cartridge battery device. Drawing from 2 carts at once creates really strong and potent vapor. This is truly good fun – but most vapers will find it harsh on the throat! The water bubbler makes these potent hits much more comfortable on the throat. This is great for ripping massive dabs, without the scorching heat and coughing fit typical with stronger carts. Both the vapor and water chambers are transparent – so you can see the amount of vapor before you inhale it!

The Hamilton PS1 device is slightly larger than the KR1, measuring 2.3” across. Although a little less stealthy, it is still positively portable. The double cartridge bubbler device looks great with a brushed copper & glass finish. This elegant look hides the deceptively powerful 1,100mAh battery. Hamilton has generously included 2x ceramic atomizers for wax, so you can switch it up. We prefer hitting oil carts in the day, and hitting the wax by night!

Lookah Seahorse Max Water Bubbler 510 Vape

The Lookah Seahorse Max is primarily an electric nectar collector, with a heated quartz tip that you dip into wax. But these coils have a 510 thread. This means you can also screw in 510 oil cartridges! Whether you choose a quartz tip or oil cart, your vapor will bubble up through the glass water tank. This conical shaped bubbler works like a dream, and the bubbler has a much higher water capacity than the Hamilton KR1 and PS1!

Lookah Seahorse Max Cart Bubbler Vape - Discount Vape Pen

Like the Hamilton devices, the water bubbler is illuminated by an LED light that reflects the heat setting from low to high; blue, purple & white. Unlike the Hamilton devices, however, the Seahorse Max isn’t freestanding. It won’t stand up independently without using the tabletop arc stand. This means it is marginally less portable than the Hamilton bubbler 510 batteries. Still, the cone shape does easily fit in your hand!

This multi-use electric nectar collector and 510 cartridge battery is a statement. There are a number of products in the Lookah Seahorse family. Check out our Lookah Seahorse Comparison guide here (the Lookah Seahorse X also has a water bubbler attachment). But the Seahorse Max lets you take huge hits from CBD oil carts, and the water filtration will cool the vapor to a nice milky cloud. This means you get all the potency of a fat hit, without the coughing fit that often comes with it!
