Yocan UNI Pro battery has a capacity of 650mAh, which is quite impressive for such a small device. Depending on how frequently you are vaping, the battery could last you a whole day. You will get at least 200 puffs before you’d need to recharge the device. The UNI Pro does not support pass-through, but it takes less than an hour to recharge it, so that’s a pro in my books. The device supports an adjustable voltage. The voltage range of the UNI Pro is 2V to 4.2V. There is an OLED screen on the device as well as two buttons for controlling the settings. The screen on the device allows you to monitor the battery level of the device as well as accurately control the settings. The Yocan UNI Pro is designed for use with pre-filled cartridges. You can use this device to vape CBD, nic salt, or oils due to its low voltage output. The lowest resistance that this device supports is 0.5ohm. The Yocan UNI Pro can fit any 510 pre-filled cartridge with a diameter of 14mm or less. It comes with an adjustable, magnetic 510 port. There is a knob that allows you to adjust the height of the 510 plate according to your liking. Also, the threaded magnetic connection ensures that your cartridge sits firmly. But that’s not all. Yocan also allows you to secure your cartridge using a shutter-like system. There is a dial near the top section of the mod that you can turn to adjust the collar. The adjustable width and height design is quite remarkable, considering that pre-filled cartridges do not come with a specific size. The Yocan UNI Pro is a device that I highly recommended mainly due to its versatility and also the fact that it comes with a screen. The mod has a 10 second preheat function. It also has a 15 seconds timeout, short-circuit protection, overheating protection, and more. Also, the UNI Pro works well. The functionality of this device leaves nothing to be desired. The Yocan UNI Pro is available at the company’s online vape shop for just $35.99. The device comes in five different colors. Yocan has many other exceptional vaping devices. If you are a retailer, you can apply for wholesale prices at this shop.
