What battery capacity do I need for daily use?

Light users consuming 10 to 20 puffs daily need 400mAh minimum. Moderate users taking 20 to 40 puffs daily benefit from 500mAh for full workday coverage without mid-day charging. Heavy users exceeding 60 puffs daily require 650mAh to avoid mid-session battery depletion during extended use. Most consumers fall into the moderate category where 500mAh provides optimal balance between capacity and device size.

How does a spring-loaded connection compare to magnetic adapter systems?

Spring-loaded connections offer faster cartridge swaps at 4 to 6 seconds while reducing thread wear by 20 to 30% compared to rigid screw-in designs. Magnetic adapters provide slower swaps at 8 to 12 seconds but protect the main device through replaceable components. For users changing carts weekly, spring-loaded provides excellent durability without extra parts. For users rotating through multiple carts daily, magnetic adapters justify the complexity by enabling indefinite device lifespan through replaceable wear components.

Is USB-C worth it for vape batteries?

USB-C provides universal cable compatibility with phones, laptops, and tablets, eliminating the need to carry multiple cable types. It charges faster than Micro-USB technology and features a reversible connector that works in either direction. For multi-year device ownership, USB-C future-proofs your investment as Micro-USB becomes obsolete in the broader tech ecosystem. The convenience of using existing cables you already carry makes USB-C particularly valuable for daily users.

What makes the hit timer feature useful?

The hit timer displays exact inhalation duration for each puff, enabling you to develop consistent technique and optimize vapor production. By tracking hit length, you understand your consumption patterns and can adjust voltage settings accordingly. This feature proves especially valuable for new users learning proper technique and experienced users wanting to maximize efficiency. Neither competitor offers hit duration tracking, making this unique to the Rokin Mini Tank Pro.

Should I choose Rokin Mini Tank Pro or Yocan Kodo Pro for moderate daily use?

For moderate daily use of 20 to 40 puffs, the Rokin Mini Tank Pro provides better value. Its 500mAh battery covers full workdays while the Kodo’s 400mAh requires mid-day charging. The Rokin includes a hit timer, dual-mode activation, and guaranteed USB-C at $29.95—the lowest price with highest feature density. Both devices offer nearly identical portability (48g vs 40g), making size differences marginal. Choose the Kodo only if you prioritize absolute minimum weight for light social use around 20 puffs daily.

When is the UNI Pro’s extra capacity worth the larger size?

The UNI Pro’s 650mAh capacity becomes necessary for heavy users consuming 60 or more puffs daily or engaging in extended multi-hour sessions. Its larger form factor proves worthwhile when smaller batteries would exhaust mid-session, creating frustrating interruptions. The magnetic adapter system also justifies the size for users rotating through multiple carts daily—the replaceable adapter protects the main device threading indefinitely. For home-based stationary use, the box mod size becomes irrelevant while the capacity advantage remains crucial.

How does puff-based activation work and why does it matter?

Puff-based activation detects when you inhale and automatically fires the battery without pressing any button. This enables discreet hand-free operation where your palm fully covers the device with no visible button pressing. It proves particularly valuable during commutes, in social situations requiring discretion, or for users with hand dexterity limitations. The Rokin Mini Tank Pro offers dual-mode operation, letting you switch between button- and puff-based firing depending on situation or preference—flexibility uncommon at this price point.

What’s the difference between 400mAh, 500mAh, and 650mAh battery life?

400mAh provides approximately 160 puffs per charge, suitable for light social use or single sessions. 500mAh delivers around 200 puffs per charge (25% more), covering full workdays for moderate users. 650mAh offers approximately 260 puffs per charge (30% more than 500mAh, 62% more than 400mAh), supporting extended multi-hour sessions for heavy users. For moderate daily use of 20 to 40 puffs, 500mAh hits the sweet spot—providing comfortable margin without requiring box mod bulk.

How does Powerwave™ prevent burnt flavors?

Powerwave™ technology automatically monitors the device’s temperature during use. When the system detects elevated temperatures from extended button holding or chain hitting, it pulses power delivery and automatically reduces voltage by 0.5V. This prevents cannabinoids from overheating and preserves terpene profiles, eliminating burnt harshness. The system works invisibly for disciplined users but provides valuable protection for casual vapers who lack perfect technique. Neither Yocan device offers automatic temperature regulation.

Which 510 battery offers best value for the money?

The Rokin Mini Tank Pro delivers the best value at $29.95 with the highest feature density in the category. It provides 500mAh capacity, digital display with hit timer (unique), button plus puff-based activation (uncommon), Powerwave™ auto temperature regulation (unique), guaranteed USB-C charging, and spring-loaded connection extending lifespan 20 to 30%. It provides the best cost-per-mAh ratio at $0.06 per mAh while packing more useful features than competitors at any price point. Over 24 months, total ownership costs remain similar across devices, making upfront feature density the key differentiator.

Empty Vape Cartridges Guide

Browse our selection of empty vape cartridges. Available in different capacities and styles, they’re perfect for pairing with our 510-thread batteries or with a vape battery you already own.

How to Buy Empty Vape Cartridges

If you’re new to filling your own cartridges, it’s important to ensure that you’re getting the right cart for your needs before you buy. Here’s what you need to know.

Choose what type of cartridge you want. Our Titan 2, Titan 3 and Easy Fill cartridges are intended for use with oil-based concentrates, which are liquid at room temperature and can be dispensed with a blunt-tip syringe. Our Wax Tank is designed for waxy concentrates.
Choose between a single-use cartridge and a refillable cartridge. Our Titan 2 and Titan 3 cartridges have tamper-proof mouthpieces and are intended to be used until they’re empty. The Easy-Fill cartridge, on the other hand, can be refilled several times.
Choose which capacity you want. Our empty vape cartridges are available in half-gram (0.5 ml) and one-gram (1.0 ml) capacities. A larger cartridge holds more oil, but smaller cartridges are more discreet and may be required for certain vape batteries.
Confirm that the cartridge will work with your vape battery.
- Some vape batteries with recessed threading or concealed designs only work with cartridges in specific width or capacity ranges.
- Our Titan vape cartridges have their air intake vents on the bottom and will work with a battery that has inhale- or button-based activation. Our Easy Fill cartridge has top airflow and requires a battery with a manual fire button.

Benefits of Empty Vape Carts

When you shop for vape carts, you can buy empty cartridges or pre-filled weed cartridges, which are filled with oil and ready to use immediately. Pre-filled cartridges offer convenience, but there are several benefits to buying empty carts instead.

Empty Carts Let You Choose Your Own Vape Oil

Although there’s a wide variety of pre-filled carts on the market today, one drawback of using pre-filled products is that you’re limited to the oil types and terpene blends that the manufacturers have chosen for you. You can’t choose your own oil and can’t refill the cartridge once it’s empty.

Empty vape carts, on the other hand, give you much more freedom because you can use your own oil from any source and can choose something that fits your exact use case.

Empty Carts Cost Less Over Time

You’ve probably noticed that pre-filled weed cartridges cost substantially more than empty carts. That’s because most of the cost is in the vape oil and not in the hardware. Empty cartridges are less expensive, and vape oil is more affordable if you purchase it in bulk rather than buying individual pre-filled cartridges. Filling your own vape cartridges can help you save a lot of money in the long run.

Empty Vape Cartridges: FAQ

How do you fill an empty vape cartridge?

Titan 2 or Titan 3 Cartridge: Insert a blunt-tip syringe between the cartridge’s central air chimney and outer wall. Squeeze the syringe until the cartridge is nearly full, leaving a bit of room for the mouthpiece. Place the mouthpiece over the cartridge and push until it snaps into place.
Easy Fill Cartridge: Insert a blunt-tip syringe and squeeze it until the oil reaches the fill line on the side of the glass. Place the mouthpiece assembly inside the cartridge, line up the threading and twist to close the cartridge.

When you fill a new cartridge, you need to allow plenty of time for the thick oil to absorb into the ceramic wick. Wait about a half hour before you start vaping.

How do you use an empty vape cartridge?

After filling the cartridge and waiting for the oil to absorb into the wick, connect the cartridge to your vape battery.

If you have a puff-activated battery, inhale gently through the cartridge to vape.
If you have a button-activated battery, inhale gently while holding the battery’s fire button.

Regardless of what type of vape battery you’re using, you should always use light air pressure to prevent a clogged cartridge. If your cartridge makes a gurgling sound, you’re puffing harder than necessary. Learn more about how to hit a vape properly.

How many times can you refill a vape cartridge?

The Titan 2 and Titan 3 cartridges have snap-fit mouthpieces and are designed to be discarded when they’re empty.
The Easy-Fill cartridge has a twist-on mouthpiece and can be refilled several times. You can continue refilling the cartridge until you’re no longer happy with the flavor.

How long do vape cartridges last?

A 1-gram cartridge typically lasts up to 300 puffs before running out of oil.
A half-gram cartridge typically lasts up to 150 puffs.

What is the Rokin Wax Tank?

The Rokin Wax Tank is designed for waxy concentrates, which are solid at room temperature. The Titan and Easy Fill cartridges, on the other hand, are designed for oily concentrates only. The Wax Tank allows you to convert almost any 510-thread battery into a dab pen on demand, eliminating the need to buy a separate device for dabbing.
