JOYETECH EGo Aio series design is a pen style AIO (all-in-one) device, which means it is capable of both mouth to lung or direct lung vaping and includes a inbuilt battery(except EGO AIO PRO C, it is W/O battery) The Ego AIO comes with a 2ml leak-proof tank similar to that of the Joyetech Cubis tank. It also features a unique top fill that has a child proof lock on it.

There are common features for the three members EGO AIO D16 EGO AIO(D19)  EGO AIO D22:

All-In-ONE Style:
eGo AIO applies all-in-one style with atomizer inserted inside, which is quite convenient to use.
Though petite but it is powerful enough to produce large vapor.
Childproof Lock to Ensure Security:
The atomizer cap is equipped with child lock so that one should press the cap to screw or unscrew the atomizer cap.All of the Joyetech Ego AIO has a great top fill which makes re-filling its 2ml tank really easy. The top fill lid is also locked with a child proof cap. This means you need to push down on it to open it. We have child proof caps on e-liquids, so why not have them on tanks? We think this is a great feature.
Spiral Structure Mouthpiece:
The inserted spiral structure mouthpiece is more beneficial for mouth inhale and is more secure.
Choose Your Color:
In power-off condition, long press the fire button to turn off the indicate light or shift among the color of red, yellow, green, blue, indigo, white or purple.
E-juice filling:
Press the cap to unscrew the atomizer cap, then inject the liquid directly into the cambered slot.We like these new AIO devices that are coming out. It gives vapers a lot of flexibility when it comes to their vape. Whilst the Ego AIO is more suited to MTL vaping, the direct lung draw isn’t too bad if you don’t mind it being more restrictive than the draw on sub ohm tanks.
Battery Life:
The Joyetech Ego AIO has a 1500mAh battery, which is pretty great considering its small size. It is smaller in size compared with the Innokin Endura T18 and yet has a 1500mAh battery compared to the 1000mAh battery on the Endura!
Coil Selection:
There are plenty of coils to choose from giving vapers plenty of options. We tried both the 0.6ohm coil and the 1.5ohm Clapton and they both vaped well and produced nice flavor and vapor. We think these might be newer version of the original Cubis coils, as we were not impressed with the initial Cubis coils. It seems Joyetech have ironed out these issues. This isn’t a device for flavor chasers and obviously can’t compare to some of the best sub ohm tanks, RDAs and RTAs. For beginners however, I think the Ego AIO provides a terrific vaping experience.
Adjustment of Air Inflow:
Rotating the ring on the atomizer cap clockwise or counterclockwise to adjust the air inflow.
Charging:
Simply charge eGo AIO by connecting it with a computer or a wall adapter via USB cable.
When it’s fully charged, the button light will go out.
Simplicity and efficiency is how you will think of Joyetech’s new product, the eGo AIO kit series. It is the first all in one kit in eGo series. Anti-leaking structure and childproof lock are applied in the device.

Vapeyaya Comments:
We are super excited about this new vaporizer, we have been testing this new Joyetech eGo AIO Kit and we are impressed. The Joyetech eGo AIO Kit is truly elegant, its ease of use is second to none, it is also small and discreet, and it performs very well thanks to its Joyetech BF Coils (the same as the coils used in the Joyetech Cubis Atomizer). The Joyetech eGo AIO Kit Tank inside light is both cool and gimmicky at the same time, we like the fact that it can be turned off easily.
