Best 18650 Batteries
Some batteries are better than others
Vaping is a very personalized experience and not every battery is the right pick for a given situation. For instance if you are using a high ohm / low wattage build, you might not pick the same battery as you would for some low sub ohm / high wattage vaping.
Batteries are typically designed in 3 ways:
- High Continous Drain Rating (A) / Low Capacity (mAh)
- Low Continous Drain / High Capacity
- Mid Continous Drain / Mid Capacity (a good general usage battery that is a good fit for a large portion of vapers)
Most of the time you might pick something right in the middle of high capacity and high amperage for a good general use battery.
Check out our battery safety guide for some more in depth detail that explains Amperage and battery capacity as well as how to stay safe with regulated vape mods as well as unregulated mech mods and more.
Best 18650s for general usage vaping
solid, all around picks
These general use batteries usually are good middle of the road picks that can suit low powered all the way to higher (but not the highest) wattage situations. They provide a good mix of battery life and amperage.

Batteries for High Wattage (Regulated Mods)
or Low Sub-Ohm Unregulated
The higher wattage ranges on regulated mods or lower ohm builds on unregulated need to be primarily concerned with the continuous drain rating on their battery selection.
Batteries that are capable of putting out more power without becoming unsafe are an absolute must.
The trade off for having a higher continuous drain (A) is that the battery capacity is not high.
Lg Hb6 18650 1500mah 30a Rating: 9/10
The LG HB6 is a very highly regarded 1500mah 30A 18650 battery that is perfect for vapers that need extra amperage for higher wattage vaping or lower ohm mech builds.
- has a 30A (continous drain) that is awesome for vaping at higher watts on a regulated mod or lower ohm builds
- *(always check your build with an ohms law calculator if you are using unregulate or mech)
Batteries with Higher Capacity
By higher capacity, it is understood to mean higher mAh. This is the rating that indicates how long a battery will last.
These typically have a lower continuous drain rating (A) meaning they are designed to be used in a higher ohm build (mech) / low wattage (regulated) situation.
These higher capacity batteries are really good fits for single coil builds and in a single battery mod.
Vaping at 12w with a 1+ohm coil one of these high capacity batteries can last more than a day or two, depending.
Samsung 30q 3000mah 15a Rating: 9/10
The Samsung 30Q is a great 3000mah that provides long battery life for low wattage all day vaping.
- Long battery life
- Mooch has tested this battery to be 20A, higher than the 15A advertised by Samsung
Lg Hg2 20a 3000mah 18650 Rating: 9/10
Often referred to as the Brownies, the HG2 provides a great mix of long lasting life (3000mah) and a suprising 20A continuous drain that will suit most vapers needs.
- 20A continuous drain
- very popular and highly regarded
- Can also come in a three pack for savings

Best Battery Charger
Vaping uses various battery types and not all chargers are created equal
Far and away the most common battery used in vaping today is the 18650 battery. However some of the more recent vape mods are starting to use the wider 26650 battery.
When looking for the right battery charger we want it to have the following features:
- handle a wide array of battery types focusing on those that we use
- 'Smart' - meaning it can show the current voltage of the battery and know when to stop charging
- high quality and well regarded manufacturer - you don't what to get cheap batteries or cheap chargers for purely safety reasons
- optional but nice: variable speed (0.5A, 1A, 2A), dedicated wall charger for max safety, extra USB port for pass through of another device such as a cell phone
Efest Luc V4 Battery Charger Rating: 9/10
This high quality, 4-channel battery charger will charge most 3.7V Li-ion or LiMn batteries including 18650 and 26650 at variable power rates of 0.5A, 1A and even 2A.
- 4-channel, variable power modes
- has additional USB output that can charge most consumer electronics
Built in safety features:
- reverse polarity protection
- short circuit protection
- over-current protection (will stop chargin when batteries are full - HUGE)
- Zero voltage activation function
Supplies for Rebuilding your own coils
Best Cotton Wicking for Coil Builds
Cotton Bacon V2 Rating: 9/10
Wick'n'Vape has come up with a really great wicking cotton blend here in Cotton Bacon version 2.
Cotton Bacon was designed with the goal of making a 100% safe, pure and durable wick. Some organic cottons can still contain some traces of organic pesticides or fragrances, but not Cotton Bacon.
Wick'N'Vape uses a U.S. grown dual fiber blend that has been cleaned thoroughly and had all non-cellulose fiber removed. This process leaves just super clean pure cotton wicking material behind.
In the resealable pouch you get several 4" 'bacon' like strips which can easily be separated, torn or cut. No more cutting a strip off your cotton pad or trying to deal with cotton balls. This stuff is very easy to build with and looks very clean.
Wick'N'Vape claims no break in period as it is a 100% tasteless wick. When tested it actually did have a very short break in period but it was only a handful of drags as opposed to the half a tank or more break in with other cottons.
Cotton Bacon can keep up with my chain vaping.This is a very absorbent wick and I have only experienced dry hits when I accidentally let the tank get too low. When this occurred, the cotton was able to recover without giving me that residual 'dry hit' burnt flavor.
Love this stuff. Provides a great vape, easy to use, and it is fairly inexpensive for the amount of cotton strips you get.
- U.S.A grown cotton, processed and cleaned for a safety
- looks great
- very short break in period and tasteless
- fast wicking, which helps prevent dry hits on chain vaping
- easy to use, separate and tear
- comes stacked in a resealable pouch; just pull a bit out like big league chew and reseal
- doesn't burn as easily when a dry hit does occur
- very low flavor retention when switching juices w/o rewicking which could be effected by the coil itself
Measuring Coil Resistance
If you don't have an ohm meter you are forced to build directly on your regulated mod and as well know they don't have a wide enough base to remain stable and upright very well.
We want an ohm meter that:
- is well constructed and from a well known manufacturer
- wide and stable base to make building easier
- is accurate (tolerance within 0.01 ohms)
- can handle a large range of resistances but focus on sub-ohm builds
- a niceties would be built in fire button, errors
Coil Master 521 Mini Ohm Reader Rating: 8/10
This easy to use ohm-reader is an accurate reader that can read down to .02 and up to 9.99. It is powered by a standard 18650 battery and is able to fire while on the device.
This ohm reader is an easy to use and accurate (some tests available show error to be 0.01 ohms at 0.1 resistance) for builders.
The shape makes it stable to build on and is designed to no have any places where juice could flood the device easily. It has two modes, read and fire modes making it perfect for vapers who like to dry fire their coils to reduce hot spots.
Full Rebuild Kit
All the tools necessary to rebuild a coil
Complete rebuild kits are a pretty easy way to get all of the tools and items you need to get started rebuilding coils.

- tweezers (metal and ceramic)
- precision clippers (diagonal pliers)
- coil kit - sized coil wrapping assist tool (2, 2.5, 3, 3.5 mm usually)
Coilmaster Diy V3 Rebuild Kit Rating: 8/10
The DIY kit is further improved in version 3 with the improved world famous Coil Master Jig and the new 521 mini ohm meter.
The complete kit comes with all of the tools you will need to build your own coils with ease:
