  • This Yocan product has everything that can suffice your need. The Yocan UNI Box Mod is a portable vaporizer that is easy to use and advanced customization with its functions and practical use.

    Here, in this post, we are going to walk you through the detailed review of this Yocan uni portable vaporizer and how to use its various functions.

    What’s in the box?

    • Instruction Manual – It does come with an instruction manual which shows you how to use it and includes some tips & tricks and disclaimers.
    • MicroUSB – You get the USB charging cable to charge the device
    • Magnetic 510 adapter
    • Yocan UNI Box Mod


    Yocan UNI box comes in four colors including the black on silver, the black on black, the red on silver, and the blue on silver. Now what’s nice about this box mod is that it is designed to be able to use a vast variety of different prefilled cartridges. It has the adjustable width which goes from 6 millimeters all the way open to 12 millimeters. You get a height adjustment from the lowest to the middle to high, depending on the height of your prefilled cartridge and it does have a window to show you the level of your cartridge regardless of height you choose.

    The body is made of aluminum and zinc alloys which make the device more durable. The main power switch is located with flashlight indicators. The charging port is placed on the side the vaporizer will be upright while it is plugged in. It has three different voltage setting. The lowest setting is 3.4V indicated by one light, 3.8V indicated by two lights, and highest 4.2V indicated with all three lights. The voltage can be set by pressing the power button in a different way that we shall discuss in the latter part of the review.

    Battery Performance

    Yocan UNI Box mod is packed with 650 mAh battery and it seems very good compared to other similar portable vaporizers. When fully charged, Uni can get around 200 hits but the number of the hit may change according to the voltage you have chosen, the resistance of the cartridge and the frequency of its use. The device took about an hour to get fully charged but users don’t get the battery indicator so they have to keep on the track the usage of the device as it battery can die without any indication.

    Performance and how to use it

    This portable device supports any cartridge without any trouble. All you have to do is, screw the cartridge on the magnetic adapter, drop it in and you will hear the magnetic connection. You can adjust the height of the cartridge according to your preference and then you have to close the width off so cartridge doesn’t rattle around and doesn’t fall out. So it’s super easy and heats up times are fast, which is good.

    To turn on the device press power switch five times. Pressing it three times will get you to voltage settings and after it gets heat up, you can inhale from the mouthpiece.

    Vapor Quality

    Although it has three voltage settings, we recommend you to use the highest setting. The only reason behind this thing is that other lower settings don’t have enough power but they can be used to save the battery. It comes with preheat function but it is useful only with cartridges that have ceramic or silica wicks so don’t use this function with cotton wicks. So the multiple voltage settings seem pointless.

    Yocan Uni Box mod costs $39.99. With this price and all customization options to fit in any 510 cartridges and 650 mAh battery life with quick charging function, this portable vaporizer is one of the best under $50 price range.

    Yocan Uni Review

    Yocan Uni Pro

    The Yocan Uni Pro is a bigger, more advanced version of the Uni. It’s larger size is used to accommodate its other new feature, the addition of precise voltage control and an OLED screen to monitor the voltage level. In every other respect, it is similar to the Uni, since it retains the innovative shutter adjustment feature that allows it to use any sized cartridge. If you want a closer look at how the Uni Pro differs from the basic Uni, keep reading.

    Kit and Accessories

    • Yocan Uni/Yocan Uni Pro
    • Magnetic 510 threaded connector
    • Micro USB charging cable

    Compatibility: The Uni and Uni Pro are compatible with pre-filled THC and CBD oil cartridges.

    Design and Features

    Yocan Uni Design

    The Uni definitely stands out from the crowded field of box style 510 batteries because of some unique design touches. One of the first that you’ll notice is the knob just beneath the opening of the cartridge receptacle. It is used to adjust a shutter in the receptacle opening that allows it to accommodate cartridges of any diameter. You just turn the knob until the shutter clamps down firmly on the cartridge so that it doesn’t rattle or shift around.

    This works in conjunction with the other notable feature, a lever on the bottom of the battery that adjusts the cartridge chamber to three different heights. So, now you can choose how far you want the mouthpiece of your cartridge to stick out. The magnetic 510 connector is taller than normal in order to enable this feature. The combination of these features makes the Uni a truly universal—which is what Uni stands for—battery that can fit any type of cartridge.

    Adding to the convenience, the Uni has a window that enables you to view the oil level of your cartridge regardless of the height you choose. The power button is placed easily within reach high on the device and the USB port is on the side, so it will stand upright while it’s charging. It is made from aluminum and zinc alloys so it feels quite durable and it has a nice heft to it as well. The Uni is a highly portable device even though the extra features make it a little taller and wider than other 510 batteries in this price range. It also has three voltage settings: 3.4V | 3.8V | 4.2V. However, you’ll probably stick with the highest one.

    Yocan Uni Pro Design

    The Uni Pro has an updated design to accommodate the brand new voltage controls and OLED screen. It is noticeably more angular than the original Uni with shallow ridges jutting out at the top and bottom of the device’s front end. Just below the top ridge lies the redesigned power button, which now has a square shape instead of the round shape of the original Uni. Below it is the OLED screen and at the bottom, just above the bottom ridge are the triangular voltage control buttons.

    The bottom ridge also features another big change from the original because that is where the USB port is now located, whereas it is located high on one side of the basic Uni. Overall, the new look suits the Uni Pro, it is a more geometric design than before, which gives it a stronger design language. Plus the new USB port placement is an improvement since you can place the Uni Pro upright or on either side while it charges. It is about the same height as the original Pro so it is still an eminently portable device.

    Yocan Uni Features

    These ultra-portable 510 batteries aren’t exactly feature-rich. In fact, their simple operation and easy portability are part of their appeal. Aside from the adjustable cartridge receptacle, the Uni keeps things simple.

    Yocan Uni Pro Features

    Naturally, the addition of precise temperature control is the Uni Pro’s most prominent feature because it gives an already customizable 510 battery even greater customization.

    Performance and Vapor Quality

    Yocan Uni and Uni Pro Performance

    The Uni and Uni Pro are capable of securely holding any cartridge used with them without any problems. The adjustable shutter does a great job of holding any cartridge nice and tight without any jiggling or looseness. Height adjustment is also great because it means that cartridges can be adjusted for comfort or stealth. The tallest height feels the most comfortable, but the lowest one is great for vaping low key. Heat up times are quick too, so no complaints on that front.

    While it’s nice in theory to have multiple voltage settings, in practice, it’s kind of pointless with the Uni. That is because many of these super small, ultra-portable vapes only have a single voltage setting, and with good reason. The reason is that they typically don’t have a lot of power, so multiple settings wouldn’t make any sense, they just output the highest voltage the battery is capable of producing.

    So, with the Uni, there isn’t really any good reason to choose any other voltage besides the highest one. The only reason why you would want to do so is if you want to preserve battery life. Otherwise, any cartridge you use is best served by the highest voltage level. The preheat function is useful, but only with cartridges that have silica or ceramic wicks. I wouldn’t recommend that you use that function with cotton wicks because they could get burnt.

    Yocan Uni Pro Vapor Quality

    The addition of granular voltage control gives the Uni Pro a slight edge over the basic Uni. Now you can more precisely select the voltage level you want instead of having to rely on presets. That allows you to choose a voltage level that better fits your vaping style. That being said, you still get a great experience with the basic Uni, the Uni Pro simply gives you more options.

    Battery Performance

    Both the Uni and the Uni Pro have a capacity of 650 mAh, which is good for a battery this size. That is good for about 200 hits, though the number varies depending on the resistance of the cartridge used with it, the voltage setting, and the frequency of its use. When it is time for a recharge, you don’t have to wait long because it charges in under an hour.

    The main downside to the Uni is that there isn’t an indicator to show you how much juice is left, so it can suddenly die on you if you don’t charge it regularly. The Uni Pro does have a battery level monitor integrated into the OLED screen, so it is more convenient than the Uni.

    Uni or Uni Pro?

    SInce there isn’t a big price difference between the two, the decision comes down to whether the additional features of the Uni Pro are worth it to you. If you want the maximum amount of customization and control over your 510 carts, then the Uni Pro is what you need. If you don’t mind giving up some control for more convenience, then the Uni should be your choice.

    The only other advantage the Uni Pro has over the Uni is that it allows you to better monitor the battery level. Ultimately, you can’t go wrong with either model, so there won’t be any buyer’s remorse no matter which one you choose.

    The Yocan Uni has a few tricks that other 510 batteries don’t, namely the ability to use any sized cartridge. Learn more in the complete review. ]]>
