Hands-on review of the Ooze Twist Slim Pen 2.0 510-thread battery: specs, performance, battery life, and value in 2025. Read our full test. | TVape CA

TL;DR:
The Ooze Twist Slim Pen 2.0 is a budget-friendly, portable 510 threaded battery with variable voltage and USB-C charging. It’s well-built and reliable but has a smaller battery, so heavy-duty users may need to charge often. Great value for basic use.

The Ooze Twist Slim Pen 2.0 is a 510 Thread Battery that is a direct upgrade from its previous version. This Vaporizer can power most cartridges and 510 threaded attachments for vaporizing concentrates.

The Ooze Pen appears to be a generic, standard pen-style battery designed for budget-conscious consumers. We can only hope the updated version lives up to this. Ooze has upgraded many features while still offering the unit at an attractive price.

In this post, we will review the updated 2.0 version, and by the end, you will have a better understanding of what this unit is capable of and whether it fits your style.

How the Twist Slim 2.0 works

How it Works

The Ooze Twist Slim Pen 2.0 works by attaching a compatible cartridge or attachment to the battery using its pulse wave technology, which, in layman’s terms, means magnetic attachment.

The device features a one-button interface that allows you to turn it on and off, as well as control the sessions. To use the Ooze Vape Pen, follow these steps:

Step 1: Fully charge the device.
Step 2: Screw on your pre-filled cartridge or solid wax attachment.
Step 3: Press the button 5 Times to power ON.
Step 4: Choose your temperature setting using the dial at the bottom.
Step 5: Press the button twice to engage Auto heating. Let the preheat cycle run.
Step 6: Hold the Button Down while you take your draw.
Step 7 Optional: Inhale from the mouthpiece without pressing the button.

Temperature Flexibility of the Ooze battery

Temperature Flexibility

In this category, we can see one of the more noticeable changes from the previous version to this one. The Ooze Pen 1.0 offered a range from 3.3 to 4.8 Volts; on the other hand, the Ooze Pen 2.0 offers a range from 2.0 to 4.0 Volts. It seems that they chose to lower the range that the device offers to cater to users who prefer more flavourful sessions. While also reducing the risk of a burnt concentrate taste, which was an issue with the previous model.

Generally, lower settings are better for flavor and smoothness, while higher settings are better for potency and cloud production. The temperature settings also impact battery life and concentrate or wax consumption, as higher settings consume more power and concentrate than lower settings.

Manufacturing quality Ooze Vape Pen

Manufacturing Quality

The Ooze Twist Slim Pen 2.0 is crafted from CNC-machined 304 stainless steel with a matte anodized finish, maintaining a weight of approximately 28 grams while still feeling sturdy in the hand. The body panels align precisely, and the control button remains firmly seated without wobble, and the magnetic 510-thread connector grips cartridges securely. Over time, the matte surface may develop light scratches, and the slim profile can feel narrow for those who prefer a more robust grip.

The unit is not designed to be the highest-performing 510 Threaded Battery out there. Still, it feels heavier than some cheap vapes that primarily use plastic to cheapen costs. We can deduce that the heating element isn’t anything special, as the manufacturers don’t mention it on their website. With that said, it is more than enough for its basic functionality. All in all, this pen delivers solid construction and reliable performance for its affordable price.

Twist Slim Vape Pen Portability

Portability

The Ooze Twist Slim Pen 2.0 measures approximately 4.5 inches in length with a diameter of roughly 0.4 inches, making it one of the more compact pen-style batteries on the market. This elongated profile fits naturally in shirt pockets, narrow purse compartments, and slim jean pockets without creating noticeable bulk.

The slim design also makes it comfortable to hold for extended periods, with the narrow grip preventing hand fatigue during longer sessions. Its lightweight construction adds to the overall portability, making it easy to forget you’re carrying it until you need it. The smooth cylindrical surface reduces snags on fabric and pocket linings, contributing to hassle-free daily carry.

While box-style 510 batteries like the Zeus ION offer different advantages with their compact rectangular footprint, the choice ultimately depends on your specific carry preferences and pocket configurations. The Ooze Twist Slim Pen 2.0 excels in scenarios where linear storage space is available and the device protruding from your hand isn’t an issue.

Ooze Slim Pen Battery Life

Battery Life

The Ooze Twist Slim Pen 2.0 features a 320 mAh battery that provides approximately an hour of continuous use. In real-world testing, the 320 mAh battery was sufficient to last through approximately half a gram of oil, which translates to moderate daily use for most users. While this capacity is on the smaller side compared to some competitors, the device includes several features that help maximize battery efficiency.

One cool addition, which is a must at this point and can be found on most 510 thread batteries, is the automatic shut-off. Ooze chose to go with 12 minutes of inactivity. For most devices, such as the Utillian 50 or the Rhotron Pro, the time is approximately 10 minutes. This power management feature prevents the common issue of accidentally leaving the device on and draining the battery. Although in my personal experience, I would say 5 minutes would be even better, since if I’m not using it for 5 minutes straight, that usually means I forgot to turn it off, and the oil has cooled down already.

Where the Ooze Twist Slim Pen 2.0 really shines is in its charging capabilities. The device offers dual charging ports via 510 Thread USB Charger (Included) and a USB-C Charger (Sold Separately). More importantly, it now does pass-through charging when using a Type-C charger. Therefore, battery life is less of an issue than it was before. This means you can continue using the device while it’s plugged in and charging, essentially eliminating downtime.

I was able to charge it within about 90 minutes using a Type-C charger. It takes a bit longer using the old-style 510 charger. The USB-C port provides faster charging speeds, while the traditional 510 threaded charger offers a backup option that screws directly onto the battery connection point. This dual charging approach provides users with flexibility in keeping their device powered up.

Overall Experience with the Twist Slim Pen

Overall Experience

In daily use, the Ooze Twist Slim Pen 2.0 delivers a solid entry-level experience that punches above its weight class. The device feels noticeably sturdier than its predecessor, with more weight in hand that immediately signals improved build quality. The sleek design and compact form factor make it highly portable and discreet, while the variable voltage control from 2.0V to 4.0V provides enough flexibility for most cartridge types.

The twist-to-adjust voltage system works intuitively, though it can be slightly finicky when dialing in precise settings. Connection issues occasionally arise with certain cartridges, typically resolved by adjusting the threading tightness. The LED indicator system is straightforward but basic, providing essential feedback without unnecessary complexity.

Build quality feels appropriate for the price point. The stainless steel body offers decent durability considering its budget positioning, though it’s clearly not designed to compete with premium 510 thread batteries. The dual charging options and pass-through capability address one of the biggest pain points in this category, making it more practical for daily use than many competitors.

Within the broader 510 battery landscape, the Ooze Twist Slim Pen 2.0 occupies a sweet spot between affordable options, such as the Yocan Ziva Pro, and feature-rich, premium devices like the Zeus Ion. The main limitation is battery capacity, which may require more frequent charging for heavy users. However, the combination of reasonable build quality, useful features, and competitive pricing makes it a solid choice for its intended market.
