Compatibility: The KandyPens 350 mAh battery is compatible with pre-filled cartridges.

Design and Features

Design

The KandyPens 350 mAh battery is a pen-style battery rather than a conceal type, which has its share of advantages and disadvantages. The biggest advantage is that it can hold any sized cartridge so you never have to worry about whether a cart will fit like you do with most conceal batteries like the Rokin Viper. Another pro is that using the 350 with a cartridge feels more natural since the combined length of the battery and cartridge feels very comfortable to hold.

Portability is where the main disadvantage lies, specifically, portability with the cartridge attached. The length that makes the 350 feel comfortable also makes it very awkward to fit into any pocket with the cartridge connected to it. It’s not too big a deal since you can just carry the cartridge and battery separately, but if you’re the type who likes to take a quick hit every now and then, you might find the pen style batteries a little inconvenient. Otherwise, the 350 is pretty unremarkable and nondescript in its design, which isn’t a bad thing if you value discretion and ease of use.

Features

The 350 mAh battery is designed to be used with cartridges that output a higher voltage than the norm, which is why its voltage settings are 3.7V, 3.9V, and 4.1V. It also has a sesh mode that keeps it turned on for a while. Since the 350 is draw activated, the battery normally only turns on when the user inhales, but with sesh mode, you can keep the heat going without any inhalation necessary. 

How to Use

1. Screw the 510 cartridge onto the battery.
2. Press the power button 5x to turn on the battery.
3. Select the voltage level from one of the presets.
4. Once the voltage is reached, inhale from the mouthpiece of the cartridge.

Performance and Vapor Quality

Performance

The 350 heats up quickly and offers users three different voltage levels for a decent amount of customization. Ultimately, it’s as convenient and simple as you would expect from a 510 battery.

Vapor Quality

Vapor quality in 510 batteries depends on the quality of the cartridge, so great cartridges, like the ones from Gold Line, give you the best results. Once you do have a great cartridge, the 350 makes a great companion for it because of the voltage selection and overall convenience. Those are the attributes that you want from a great 510 battery so the 350 has everything you need.  

Battery Performance

You don’t need any guesses as to the size of the battery here since KandyPens had the good sense to include it in the title. It’s not the biggest you will ever see in a 510 battery, but it lasts for a while before it needs to be recharged. Recharges take about an hour so you won’t be waiting long. I don’t like the key fob style charger used with the 350, mainly because I prefer a charging cable, but that’s more of a personal issue than a serious problem.
