Here's the components of a modern
Advanced Device Kit
Although both create a vapor by bringing liquid in to contact with an electrically charged coil that is where the similarities end. The Battery
(also referred to as a Mod, Box Mod. Personal Vaporizer or PV) - A modern battery is much larger & more powerful and the power is adjustable. A typical battery can supply from 5 watts to upwards of 200 depending on the model and most are also capable of coil temperature control when using a compatible coil, Nickel or NI, Titanium or TI and Stainless Steel or SS. When using the temperature control feature the user sets a desired coil temperature and the battery automatically controls the power to achieve and maintain it.
As for capacity, the old 510 batteries had a storage capacity of 180 mAh (milliamp hours) while a Mod battery will typically feature a capacity of 2000 to 5000 mAh. Keep in mind though that these devices use much more power & they also go through liquid more quickly.
An important distinction with Mod batteries is whether they use an internal power cell(s) (permanent) or external (removable) batteries, i.e. 18650. The internal mods have the advantages of increased convenience as nothing has to be disassembled to recharge them and they can be used while they are charging, they also are generally smaller in size & lighter. With an external Mod the batteries in most cases are removed for charging (although many can be charged using a built in USB port). One key advantage to the removable batteries is that when the batteries no longer charge properly you simply replace the batteries and not the entire Box Mod. The Tank
(also referred to a Tank Atomizer, Subohm Tank or Subtank) - In the illustration above components 2-5 comprise the tank. Tanks are available in a wide range of liquid capacities, coil types, metal the coil is made of and also how they are filled with liquid. Most of the newer tanks allow you to fill easily without removal from the battery or any disassembly. Coils made of Nickel (NI), Titanium (TI) & Stainless Steel (SS) are capable of temperature control.
