Over 2 packs/day: High to Extra High

Getting Started
When you first get your device, you will want to set it up properly for the best experience.

First, fully charge your batteries. Place them in the charger until the light turns green. Some recommend to charge for a minimum of 4 hours, regardless of the green light.

Second, blow out your atomizer. The atomizer comes from the factory with a “primer fluid” to keep it moist, but it tastes terrible. Simply place your mouth over the threaded end and blow hard onto a paper towel until no more liquid comes out.

Third, fill your cartridge. DO NOT OVERFILL. Use the dropper to drip the liquid until it no longer absorbs into the filler. Usually around 15 drops. If some liquid pools at the top, dab with a paper towel.

Fourth, drip TWO drops directly onto the metal coil in the atomizer.

Finally, attach the cartridge to the atomizer and then screw the atomizer onto the fully charged battery.

NOTE: There may still be some primer fluid on the atomizer, so you want to take a few puffs into your mouth and blow it directly out, to get the liquid flowing into the atomizer. Give 20-30 seconds between puffs, so the atomizer doesn’t get too hot. If you continue to taste a burnt/chemical taste, this is the atomizer burning off the primer fluid. Continue to “puff & blow” until the taste diminishes. If the taste gets worse, add two more drops directly onto atomizer again and continue to “puff and blow.”

For more information on the “burnt/bitter/chemical” taste issues, see this link: http://www.e-cigarette-forum.com/forum/tips-tricks/42077-10-tips-avoid-harsh-burnt-taste-510-atomizers.html

Once the primer fluid has burned off, you should be good for up to 20 puffs before you have to "top off" (adding a couple of drops to the filler) or refilling. Read the sections below on cartridge modifications for optimal filling techniques and using the batteries properly.

Remember that this is NOT a tobacco cigarette. You don't draw on it as you would a cigarette. You want to take it easy on the draw. Slowly inhale, to allow the atomizer time to heat the liquid. Don't draw on it hard or you'll end up with a mouthful of unvaporized liquid!

510 Components

Battery
This is what powers your device. It is recommended that you charge it fully before first use. Batteries come in assorted body colors and LED colors. They are also available with no LED. Batteries come in automatic and manual styles.

Automatic:
The automatic has a switch built into it that activates by the air that rushes through it when you inhale. It is good for hands-free use, however, it is very sensitive and is known to activate by sound and light impact. This may cause it to turn on while in a pocket or purse and may have to be recharged more frequently. Automatic batteries also have an automatic shutoff built in that frustrates some users who want a longer, deeper draw. The automatic batteries have a hole in them to allow air flow for the switch. Consequently, it is recommended that caution be used not to overfill the cartridge, direct drip or flood the atomizer, because it can get into the battery. (More on flooding & dripping later.)

When using an automatic battery, it is recommended to employ a "primer puff" before every draw, to pre-heat the atomizer for optimal vapor production. This is taking a short puff, followed by the actual inhale draw.

Manual:
The manual switch activated with a button. It is generally the more popular option with experienced vapers, because it allows more control over the draw and heat. It also allows the atomizer to get a little hotter and produce more vapor. It usually does not have a shutoff built in. With this kind of use, the battery life tends to be shorter. The manual battery does not have any hole and therefore, better adapted for dripping and less susceptible to damage from the liquid.

When using a manual battery, a "primer puff" is not needed. Simply press the button before you begin your draw, then release after you are finished.

Regular & Extra Long Batteries:
The 510 has two lengths of batteries available. The regular length is what comes in most kits. An extra long version is available from some vendors. The extra long battery, also known as the Titan MEGA, lasts longer, however, it takes longer to charge and will not fit in the 510 Personal Charging Case.

USB Pass-through:
This accessory allows for direct power from a computer or AC outlet. It looks like a battery, but has a cord with a USB plug. It can be plugged directly into a computer USB port or into a USB AC or Car Adapter and plugged into an AC outlet or car lighter outlet. There are two versions of this accessory – one has an actual battery that is continuously recharged by the USB port (in a small battery case near the plug) and the other just has wires that go directly from the connector to the USB plug. Neither has an LED.

Atomizer
The atomizer (atty) is a heating element that heats up the liquid and turns it into a vapor. One end screws into the battery and the other end fits the cartridge. It consists of a small pot or chamber, which holds a reserve of the liquid. There is a metal mesh coil or “bridge,” which draws in the liquid from the cartridge to a fiberglass wick. The heating element heats up the liquid and turns it into a vapor, which is then drawn back through vents in the mouthpiece by the user. The 510 atomizer is often the source of issues with performance and taste.

Flooding:
If you get a “gurgling” sound when you draw on the device, you have flooded the atomizer. This means that there is too much liquid in the atomizer for it to properly vaporize. Remove the atomizer from the battery and cartridge and blow out the excess liquid onto a paper towel from the threaded end.

Cleaning:
The atomizers, by design, are not meant to last forever. However, you may be able to extend the life of your atomizer and improve performance with occasional cleaning. There are many tried and UN-proven methods for cleaning, some more successful than others. Most agree that occasionally blowing out the atomizer is a safe practice, as the liquid tends to build up in the atomizer.

Some signs that your atomizers may need cleaning are:
-Reduced vapor production
-Hard or difficult draw
-Burnt/Harsh taste

Here are the recommendations by the manufacturer, Joye Technologies: 510 usage and maintenance instructions from Joye Technology

The following cleaning methods have been tried by various ECF members. It is advised that these cleaning methods be tried ONLY AS A LAST RESORT. There are many, many opinions on cleaning and it is STRONGLY suggested that you read the various threads on this topic.

Hot Water Rinse: Run under VERY hot water. Dry 48 hours.

Soaking/Baths: Soak in one of the following; Everclear or 100 proof vodka, isopropyl alcohol, diet cola, Polident (denture cleaner), hydrogen peroxide, vinegar or ice machine cleaner. Rinse VERY well under hot running water. Dry 48 hours.

http://www.e-cigarette-forum.com/forum/experiments-equipment/10475-cola-method-taken-another-level-works.html

Hot Water Boil: Boil for 2-3 minutes, stirring continuously. Dry 48 hours.

Hot Water Boil w/Baking Soda: As above but with 1 tbsp baking soda added to the water. Rinse well. Dry 48 hours.

Dry Burn: Rinse under hot water. Dry 48 hours. Attach atomizer to battery. Press and hold battery button 4-7 seconds. Repeat until there is no vapor produced during the dry burn.

Burnt/Chemical/Bad Tastehttp://www.e-cigarette-forum.com/forum/tips-tricks/42077-10-tips-avoid-harsh-burnt-taste-510-atomizers.html

Cartridge/Mouthpiece
The cartridge on a 510 is more complex than it seems at first glance. It is a combination of mouthpiece and filler/liquid chamber. One end is open to a chamber to add the filler material and liquid, the other end has another, smaller chamber, which is closed off with a removable end cap, with a hole in the center. This end can be round or have a “whistle tip,” which is flattened on two sides. If you look closely, there are two slots on the flat sides of the liquid chamber, going into the mouthpiece chamber. This is how the vapor gets from the atomizer to the mouth. The vapor does not travel through the filler material, it travels around the liquid chamber, into the mouthpiece chamber. When the filler end is fitted into the atomizer, the metal coil acts like a wick, drawing the liquid into the atomizer to be vaporized.

Loose Cartridges:
The diameter of 510 atomizer was recently made larger, resulting in the older, smaller cartridges not fitting properly and falling off. Loose cartridges were also a problem with the M-401 model and an ECF member came up with a modification to fix the problem. With the 510, you would make the modification to the outside of the cartridge, but you can get the idea here: Fixing loose cartridges on an M-401 electronic Cigarette

Filler
This is the material inside the refillable cartridge. It is a polyester batting material. It acts like a sponge, to keep the liquid from spilling out of the cartridge and available for the atomizer wick. This may be removed and replaced with another material, which is called a “modification” or “mod” for short. The liquid can eventually get "gummy" and affect the taste, throat hit or draw, so the filler should occasionally be removed, rinsed and dried for reuse.

Filler Modifications:

More Ideas: http://www.e-cigarette-forum.com/forum/cartridge-mods/index2.html

Dripping:
Some owners eschew filler altogether and choose to "direct drip." This simply means to take the filler out of the cartridge and "drip" 2-3 drops of liquid directly on the atomizer coil. Then, replace the mouthpiece and use as normal. Be careful not to over drip or you will flood the atomizer! Proponents of this method feel this gives a more consistant vapor and throat hit, without relying on filler materials.

Here is a modification made to aid with the drip method: Direct Drip Cart Mod (DDC)

There is also a cool little gadget for dripping called an e-Dobbit: .. : Sticker to it!, Vinyl Graphics & Lettering

Dipping:
Similar to dripping, dipping delivers the liquid directly to the atomizer. Dipping does not work well with the 510 atomizer, as the coil is recessed within its casing. Other models have an exposed atomizer coil, which allows for the owner to "dip" the coil into a small container of liquid. If you would like to try dipping with your 510, you can purchase a 306 model atomizer, which is compatible with the 510 battery. Proponents of this method sometimes prefer this over dripping, because it is less likely to flood the atomizer.

Chargers
There are three common chargers available for most 510 batteries: USB, AC and PCC.

USB:
Charges a single battery and plugs directly into your computer’s USB port. Place the threaded end of the battery in the hole and screw it in place until the light turns red. It will turn green when charged.

AC:
Charges a single battery and plug into a standard wall outlet. Has a removable cord. Also has a port for a car charger. Place the threaded end of the battery in the hole and screw it in place until the light turns red. It will turn green when charged.

PCC (Personal Charging Case):
Charges a single battery and also holds one atomizer and two cartridges. Plugs into a USB port, with a mini USB on one end and a standard USB on the other. Place the battery in the far right hole, thread side down. The pressure from the lid will push it into place to charge - it does not screw in place.

There are three lights on the PCC:
Top Light - Red indicates a battery is charging. Turns off when charged.
Middle Light - Red indicates the PCC battery is too low to charge the battery inside.
Bottom Light - Red indicates the PCC needs to be charged. Green means the PCC is fully charged and ready for your battery.

USB to AC Adapter: Allows any USB cord to plug into a standard AC outlet.

USB Car Charger Adapter: Allows any USB cord to plug into a car lighter outlet.

Car Charger: Allows the AC charger to charge a battery using a car lighter outlet.

e-Liquid
This is the liquid which gets vaporized by the atomizer. If you bought pre-filled cartridges, it has already been filled by the manufacturer. If you bought empty cartridges, you need to buy the liquid from a reputable vendor. Some liquids are factory-made in China and resold directly to the customers. Some liquids are custom-made by the vendor. The best way to decide on which liquid to buy is to visit the Supporting Suppliers forums: http://www.e-cigarette-forum.com/forum/supporting-suppliers/ and read what their customers have to say about them.

e-Liquid is made of water, propylene or vegetable glycol, nicotine and food flavoring. Some also contain glycerine.

Common Nicotine Levels:
NONE (Zero)
Extra Low: 6-8MG
Low: 10-12mg
Medium: 16-18mg
High: 24-26mg
Extra High: 36mg
For Mixing/Diluting Only: 48mg, 60mg

Some vendors have created special mixes for higher temperature devices, which also work well with the 510 manual batteries. No one can tell you what tastes the best, it’s a matter of trial and error. It’s recommended that you buy samples from different vendors and find what works for you.

You can mix flavors to create your own. A couple of drops of "cola" with a drop or two of "vanilla" makes a great vanilla coke! Experiment and have fun. Don't limit yourself to just tobacco flavors, either - it's one of the best features of vaping.

Some people new to vaping complain that the flavors of the liquids are too faint or all taste the same in the 510. Give it some time. You have to break in/season the atomizer, to really get the full flavor. Also, after being off tobacco cigarettes for a few days, your taste buds will start to recover and the flavors will become more distinct. Some vendors even offer an option to double the flavor in their liquids. After a while, you be noticing all of the subtle tastes and smells you've been missing all of this time!

If you like menthol, you can increase the menthol content of your liquid by adding menthol crystals or menthol drops. Suprisingly, menthol liquid is popular with both former menthol tobacco smokers and non-menthol smokers alike. It's believed to add extra throat hit to other flavors, as well. Read more: Menthol fans!

It's recommended that you use a fresh atomizer for each flavor, as it's difficult to get certain flavors, such as menthol or clove, out if the atomizer wick. You don't want to have to do a throrough cleaning and wait 48 hours for drying time, every time you want to change flavors. So, get a new atomizer for each flavor you use. Some people label their atomizers or color code it with paint/nailpolish. You can also put the atomizer, with the cartridge, into a Ziploc Snack Bag with it's bottle, to keep them organized.

Governor Schwarzenegger Protects Adult Consumers’ Access to E-Cigarettes

Industry hails veto of anti-smoking alternative bill as victory for consumers, common sense Washington, D.C.

October 12, 2009

Matt Salmon, president of the Electronic Cigarette Association (ECA), today praised California Governor Schwarzenegger’s wise decision to veto Senate Bill 400, which would have banned electronic cigarette sales in the state, protecting adult consumers’ access to these alternative smoking devices.

“This is not just a victory for consumers and common sense but is smart public policy as well,” said Salmon. “Rejecting this bill is the right step and should serve as a model for other states to follow.”

In his veto message, Governor Schwarzenegger reiterated the stance of the ECA that strongly supports restricting access of electronic cigarettes to children under the age of 18. “We agree with the original intent of SB 400 to ban sales to those under the legal smoking age. And we support that on a national level as well,” added Salmon.

The Governor affirmed that this restriction should not apply to adult consumers: “If adults want to purchase and consume these products with an understanding of the associated health risks, they should be able to do so unless and until federal law changes the legal status of these tobacco products.”

The ECA actively communicated to the Governor its members’ concerns about the bill and the fact that banning these electronic cigarettes would disenfranchise thousands of California adult smokers who have difficulty quitting but want an alternative to combustible cigarettes without the host of carcinogens and harmful chemicals. Salmon credited this legislative victory to the efforts of thousands of consumers and ECA members who appealed directly to Governor Schwarzenegger to protect their rights.

“While we know that combustible tobacco smoking kills over 400,000 Americans annually, and the percentage of smokers that quit every year is dismally low, we ought to be looking for more alternatives to traditional combustible tobacco products,” said Salmon.

Electronic cigarette kits usually include the electronic cigarette, a replaceable cartridge pack (that may or may not contain nicotine), rechargeable lithium batteries, and a charger. There is some variation between different companies in what is included in their starter kit, but all components are listed on their Web sites. While ECA members do not market these devices as a healthy alternative or smoking cessation device, it is clear that they do not contain the harmful tars and hundreds of carcinogens that consumers get from combustible tobacco products.

“We look forward to working with all government agencies, including the FDA, to ensure that consumers who want an alternative to combustible tobacco products have access to e-cigarettes that contain fewer harmful substances and produce no secondhand smoke,” concluded Salmon.

FDA Miscalculates Real Danger to Smokers

The FDA is at a loss.

It knows why people want to quit smoking tobacco cigarettes - exposure to first and second hand smoke is proven to cause numerous health problems, from heart disease to cancer.

Up until now, the only way thought to quit smoking was to cure nicotine addiction. Beat the nicotine cravings, beat the urge to smoke - or so the theory goes. Consequently, the term "smoking cessation" has become synonymous with curing nicotine addiction with the use of Nicotine Replacement Therapies or NRTs.

However, focusing solely on nicotine addiction has been proven to be ineffective.

FDA-approved medications are tested in clinical trials and the enthusiasm of participants, close monitoring and counseling may all inflate the success numbers found in those studies, according to a report released in a 2002 edition of Journal of the American Medical Association (Vol. 288, No. 10: 1260-1264). "These products are designed to help with the cravings associated with smoking, but not the behavioral aspects," stated co-author Professor Elizabeth Gilpin, of the University of California. The report also pointed out that NRTs were originally by prescription only, giving patients trying to quit access to a physician's support and behavioral counseling.(1)

In the 2006 study, "Nicotine replacement therapy for long-term smoking cessation: a meta-analysis," the authors wrote, "Due to relapse, the overall efficacy of NRT treatment in terms of additional ex-smokers declined from 10.7% over and above placebo (6.6% to 14.8%) after one year to 7.2% (3.8% to 11.3%) at an average of 4.3 years follow up. "

"Because the long-term benefit of NRT is modest," the study concluded, "tobacco dependence treatment might be better viewed as a chronic disorder, requiring repeated episodes of treatment."(2)

So, why the extraordinary failure rate?

What Nicotine Replacement Therapy and other medications designed to solely treat nicotine addiction fail to address is the basic human tendencies of habit and ritual. Smokers don't just crave the nicotine. The physical act of smoking becomes integrated into their everyday activities to the point where the smokers are essentially lost without it. They become loyal to their cigarette brand. They find just the right holder and the best lighter.

Certain activities trigger the desire to light up, mostly common activities such as morning coffee, driving or after a meal. Just as people may bite on pen caps, twirl their hair or chew their lip, the act of taking a cigarette out, fiddling with it, lighting it, the sensation of inhaling the smoke, the feel of the smoke at the back of the throat and seeing the smoke swirling in the air are all part of the comfort mechanism for a smoker. That comforting ritual and habit is far and away the greatest reason why treatments that focus solely on nicotine addiction fail. After a year, there shouldn't be any more cravings for nicotine. Ask smokers why they started up again and they'll most likely point to a stressful event or period that caused them to seek out the comforting ritual of smoking, giving them a sense of control over their stress, not the craving for nicotine.

Nicotine is already acknowledged by the FDA and medical professionals to be one of the safer ingredients in tobacco cigarettes, as it's commonly used medically to assist smokers in the attempt to quit. Therefore, the FDA and medical professionals must agree that the greater danger in cigarettes is contained in the actual smoke, the known source of the tar, ammonia, acetone, carbon monoxide and other toxins and carcinogens.(3) So, why isn't the urgency to improve the smoker's health focused on removing the exposure to smoke, rather than the addiction to nicotine? Up until now, there hasn't been any alternative.

Enter the Personal Vaporizer or "electronic cigarette," a device whose growing popularity has left the FDA at a loss of how to properly categorize it.

For the first time in history, there is a device which, when used in lieu of tobacco cigarettes, targets the smoker's ritual and habit instead of the nicotine addiction. Nicotine is still present in the electronic cigarette and smokers are still comforted by the look and feel, as if they are still smoking, but the component most lethal to tobacco cigarette smokers and bystanders - the smoke - is absent.

Unlike NRTs, the consumer decides when and if they will reduce or eliminate their nicotine intake. The nicotine liquid sold by reputable manufacturers is available in measured levels of nicotine content, chosen by the consumer to match their former tobacco use. It consists of water, propylene glycol, nicotine and flavoring. Propylene glycol, a substance which is generally recognized as safe and approved for human inhalation by the EPA (4), is often confused with diethylene glycol, which is a toxic ingredient found in tobacco cigarettes (and antifreeze.) Propylene glycol is actually FDA-approved for human consumption and is used as a base for consumable products such as imitation vanilla and toothpaste and is the same substance used to create theatrical fog.

In July 2009, the FDA announced that laboratory analysis of two brands of electronic cigarettes found traces (approximately 1%) of diethylene glycol in one cartridge and certain tobacco-specific toxins, which are also found in tobacco cigarettes and FDA-approved NRTs. (5) However, the agency's analysis was also quite positive in the fact that researchers did not find the dangerous levels of toxins and carcinogens, such as the tar, carbon monoxide, ammonia, etc., that is found in tobacco smoke.(6)

The FDA, however, objected to some manufacturers' claims that the electronic cigarette is a smoking cessation device - falling back on the now outdated view that smoking cessation must involve nicotine replacement therapy - and electronic cigarettes have not been proven effective as NRTs through the proper studies. Electronic cigarette companies countered that their products are not intended for use as an NRT smoking cessation device, but rather as a smokeless alternative - one that mimics the habits and rituals of tobacco smoking, without giving up the nicotine. An FDA rebuttal cited numerous reports, including testimonials on vendor web sites, that consumers were using the device as a way to quit smoking and that indicated "intended use." As all NRTs fall under FDA jurisdiction, electronic cigarettes, the agency maintained, must be tested and shown to be as effective as other medicinal drugs.

Another July 2009 press release stated, "The FDA has been examining and detaining shipments of e-cigarettes at the border and products it has examined thus far meet the definition of a combination drug-device product under the Federal Food, Drug, and Cosmetic Act. The FDA has been challenged regarding its jurisdiction over certain e-cigarettes in a case currently pending in federal district court. The agency is also planning additional activities to address its concerns about these products." (7)

Most would agree that the FDA has some valid points. The nicotine liquid does need to be regulated for consistency in ingredients, labeling and safe packaging. Studies should be done for the long-term effects of its use. Laws should be passed limiting the use and sale to legal adults. However, in its zeal to gain control over the regulation of electronic cigarettes, the FDA insisted that the product be removed from the market altogether, rather than cautious use while the studies are being made. This caused a snowball of misinformation in the media and gave the general public the impression that electronic cigarettes have all of the same dangers of tobacco cigarettes, if not worse. These concerns have prompted several anti-smoking groups and legislators to call for a complete ban of electronic cigarettes, ignoring the undeniable fact that, in the absence of an alternative, most electronic cigarette owners will return to smoking deadly tobacco cigarettes.

Because the FDA is at a loss as to how to categorize electronic cigarettes as a smoking cessation device without classification as an NRT and furthermore, by insisting that a smoking cessation device must address nicotine addiction, many believe the agency has miscalculated the greater danger facing current tobacco smokers - the actual smoke.
