World's First UL Certified Vape Pen

Vaping Safety

The Joyetech eGo AIO, an acronym that stands for All-In-One, is a graceful design that has stood the test of time. It has also withstood the rigors of safety certification testing at Underwriters Laboratories (UL). As the world's first UL certified vape pen, it brings the issue of vaping safety back into the forefront. Vape pens have an enviable safety track record. The London Fire Brigade recommended smokers switch to e-cigs because vaping prevents house fires. This is just another example of the UK being light years ahead of the US in regards to the benefits of vaping. Perhaps because of this record of safety, the occasional vape battery injury almost always goes viral and results in plenty of hand-wringing from vaping critics.The truth behind the headlines is far different. There has been one recorded vape battery fatality. In the US alone, house fires caused by cigarettes have killed an average of 625 people a year since 2003. Vaping devices have been proven reliable but every vaper should be well-informed about battery safety. This is especially true for anyone who uses a vape mod, where swapping out the 18650 or 21700 lithium ion batteries is a regular occurence. For common sense pointers, check out our 18650 battery safety guide.  At the bottom of this article is an infographic that outlines these safety procedures, which also apply to the slightly larger 21700 batteries.

UL 8139 Certification for Vaping Devices

Underwriters Laboratories (UL), a recognized global authority on battery safety testing, developed UL 8139 as a voluntary industry standard to help vape device manufacturers address potential safety issues with lithium ion batteries. Joytech eGo AIO is the first device to complete the intensive certification process. The UL 8139 testing procedures focus on the battery:

  • Battery management system evaluation for normal use and foreseeable misuse
  • Mechanical stress testing
  • Accidental activation
  • Compatibility with interconnected systems
  • Environmental resilience

Joyetech eGo AIO

With its classic tube mod design, the eGo AIO wants to be all things to all vapers. It has a few obvious audiences: smokers looking to switch to vaping, fence sitters who occasionally vape, vapers who are looking for a device with a bit more cloud production than a cig-a-like and anyone in the market for a discrete tube mod for personal use. For all intents and purposes, it is a subohm starter kit. The AIO is an efficient piece of kit. Powered by 1500 mAh battery and sporting a 0.6 ohm coil, the AIO measures a bit over four and a half inches in length. It weighs about two and a half ounces and has a juice capacity of 2 ml. If primed properly, the coils have a decent life and  they have been paired to the specific power output of the eGo AIO.  It is not a particularly thirsty device, another bonus for someone new to vaping. The AIO features an advanced anti-leaking structure, boldly described as “the best” in company literature, and the tank cap relies on a simple childproof locking mechanism to provide additional piece of mind. Safety is a recurring theme with the AIO. It has two sets of battery protection circuitry. This prevents over-charging, over-current and over-discharging. As described earlier, a big selling point of the AIO is its attention to detail and the fact it was recognized by the American National Standards Institute (ANSI) as the first UL certified vape pen. As far as performance, the 0.6 ohm coil is well-matched to the AIO’s power. You can track battery life easily with a seven color indicator life. There are two mouth pieces available. The spiral design is meant for mouth to lung hits, and the standard design for straight lung hits. You can customize your experience with the adjustable air inlets. For a smaller device, the AIO generates great flavor and a decent amount of vapor. This is pretty much a perfect device for someone who is looking to transition to vaping from smoking or has already tried smaller, higher resistance devices and is looking for a bit more cloud production. It has enough power to be a convenient device for anyone who does not want to lug around a larger box mod.


There is a reason why this device has sold well. It is well-engineered, reliable, has a user friendly design and provides quite solid flavor and cloud performance. It is a sleek, small and attractive device. By removing multiple coil options and swappable batteries from the equation, it is truly an “all-in-one” device. The AIO comes in a range of colors and Joyetech did a great job with the ergonomics. From a clearly marked “max fill” line on the tank to the action on the fire button, this tube mod makes vaping easy. The tolerances are outstanding and everything is where it should be. Because the eGo AIO serves as such an effective entry into subohm vaping, it makes sense that Joyetech would go to the effort get it UL certified. A vaper who is already deep into powerful box mods is probably already sold on the benefits vaping and the safety of the devices. Someone who is looking to dip their toe in the water for the first time, or invest in a slightly more powerful device, is more likely to be swayed by UL 8139 safety certification. Let’s hope that the UL certification helps convince fence sitting smokers to take the plunge into the world of vaping. The AIO has everything you need to start your vaping journey, but there is no reason that veteran vapers can’t enjoy its small size and commendable performance. The safety certification is an added bonus.
