Design and Features
The Uni definitely stands out from the crowded field of box style 510 batteries like the KandyPens C-Box 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.
Ultra-portable 510 batteries like the Atmos Micro Pal 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.
How to Use
- Screw your cartridge onto the magnetic adapter and then place it into the cartridge chamber.
- Use the knob to adjust the shutter until it holds the cartridge firmly in place.
- (Optional) Use the lever to adjust the cartridge to the height you find most comfortable.
- Press the power button five times to turn on the device.
- Press the power button three times to select a voltage setting.
- Once the voltage has been reached, inhale from the mouthpiece.
Performance and Vapor Quality
The Uni is capable of securely holding any cartridge from Gold Line to Hemp Bombs 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.
The Uni has 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 battery 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.
