The Curator's Notes: Aspire's Dynamo & Nepho
- 24 Jan, 2019
Aspire is one of our featured brands at Coval Vapes, largely because of their innovative approach to vaping and track record of reliability. The Dynamo & Nepho takes the “dual battery mod with a sub-ohm tank” category and improves it in every way. The Dynamo is a dual battery mod (18650, 20700 or 21700) and charges via micro-USB. The included Nepho tank is a refinement of what a sub-ohm tank should be and a staff favorite at Coval. Let’s dive into what makes this setup so special.
The first thing you see when you turn on the Dynamo is a bright and very readable display. A number of customers have told us the display is the first time they can easily read a mod's screen in sunlight. The screen is slightly recessed to protect it from scratches when laid down. The 2 inch circular TFT screen can also display the current time with 11 different watch faces. When it's in wattage mode, the Dynamo will display the wattage and voltage output and atomizer resistance.
The Dynamo can fire up to 220w and has wattage, voltage, bypass and temperature control modes built in. While the Dynamo can use 18650 batteries with the included silicone adapter, we recommend using a pair of the Sherlock Hohm batteries.The micro-USB port allows the Dynamo to be charged up to 2A. A spring loaded 510 adapter can accommodate almost any atomizer on the market.
When you insert the batteries the screen will come on. Like all aspire mods, 5 clicks unlocks the mod and 5 clicks will lock the mod.When the mod is locked, holding down the fire button for 2 seconds will turn the mod completely off. Pressing the fire button and "up" button at the same time will allow you to change display - modes, data, system, time and about. The wattage adjustment buttons let you scroll through the modes and the fire button will select the mode.
Most users will stay in wattage mode. When in wattage mode, hold the up & down button to choose between "soft", "normal" and "hard" for power output. Soft will ramp the power up slower, normal will fire like a normal mod, and hard will ramp the power up faster with a little extra boost to heat the coil quicker. You can go from 5w to 220w. Bypass mode will behave like a mechanical mod. CPS mode is for custom power curves - similar to the "soft", "normal" and "hard" but with more flexibility and customization.
TCR is for temperature control and is only recommended for advanced users with knowledge of temperature control and compatible coils.This lets you limit the output based on the temperature of the coil which can be useful for flavor. The most common use case is to prevent dry hits by limiting the temperature based on the wicking material used in your coil. Again, this is for advanced users. If you want to learn more, stop by any Coval Vapes location or email us and we will be able to explain more about it and provide some resources for learning more about it.
In the system menu, you can change the automatic cut-off from 5 to 15 seconds, the screen on time from 5 to 120 seconds, the watch time from 5 seconds to 30 minutes, screen brightness and main UI settings.
The Nepho tank is one of the, if not the best sub-ohm tank we've come across. Rather than have thirty coil options which can be confusing at best, there are only two coils at this time. The kanthal coil, similar to what most vapers are used to, has a recommended wattage range of 65-75w and a resistance of 0.5 ohms. The mesh coil is 60-75w with a resistance of 0.15 ohms.
We've found most users prefer the kanthal coil for a slightly tighter draw and lower wattages and the mesh coil for an airier vape and higher wattages. I personally prefer tobacco and cream flavors on the kanthal coil while I prefer fruits, menthols and desserts on the mesh coil which has more surface area.
The Nepho coils have giant wicking holes and has no trouble keeping up with chain vaping. Replacing the coils is easy - remove the base, lift out the coil, insert the new coil, replace the base and wait for the new coil to wick. This prevents eLiquid from getting on your fingers and reducing the mess that can sometimes be present when changing coils. We recommend letting the tank sit for 5 minutes with a new coil to prevent dry hits and allow the cotton to fully saturate. We also recommend filling the tank when it's at ~20% to extend coil life.
Aspire's innovation extends to the filling of the Nepho tank by incorporating a child resistant lock mechanism. To fill the Nepho, lift the top cap, push where the triangle is located to reveal the fill hole. Fill your tank and then slide the cap back and then gently push it down to lock it. The best benefit of this for me is, it prevents the tank from opening in your pocket. I've had a number of sub-ohm tanks that leak in my pocket because the cap got pushed just right and opened. This innovative top cap design prevents this.
The airflow is controlled with a cyclops style design with three inlets. Rotating the airflow control ring lets you completely cut off the airflow or fully open it up for an airy vape. There is just enough resistance to prevent accidentally changing your airflow while also being easy to adjust. I typically have my airflow ~1/3 closed off for my style of vaping.
I'm sure by now you see why we love the Dynamo and Nepho - it took the "dual battery mod and sub-ohm tank" format and refined it into an incredible combination. The dual batteries and high output ensures long battery life even with higher wattages. The tank improves on the typical sub-ohm tank in every way. The coils last a long time and wick very quickly while providing outstanding flavor.
