To access the menu of options and adjust the voltage on the ProVari, you simply press the button 6 times in a row. The digital display will turn on and you can flip through the voltage settings with each button press. Once you are done making changes, leave the button idle for 4 seconds and the ProVari will automatically save your settings and the display will turn off. You are now ready to vape!

Your settings will always be saved even when you change the batteries.

Lighted Pushbutton

 ProVari-variable-voltage6

The ProVari variable voltage e-cig has a translucent lighted pushbutton that alerts you when the battery is low by slowly flashing a red light.  When the battery is fully depleted and needs to be recharged, the light will flash rapidly and the ProVari will turn itself off to protect the battery from over-discharge.

The lighted pushbutton can also light up every time you press the button while using. This function can be toggled on/off in the menu.

ProVari with AccuSet™ technology

Provari_variable voltageThe built-in dynamic self-calibration algorithm keeps the output voltage accurate to 1% or better over the life of the product. The ProVari will constantly monitor and adjust itself to ensure you always get accurate voltage settings. Now a ProVari owner can tell another ProVari owner to try a certain voltage setting with their favorite brand and flavor of e-liquid and the flavor experience can be shared.
Every device will autotune itself so it's always precise!

Batteries

The standard ProVari takes a single 18490/18500 battery.

AW_18490

The ProVari uses a special boost circuit to adjust the voltage to your desired level and it only needs a single battery to operate.
We recommend only using AW IMR high drain batteries in your ProVari.
You must use batteries that have a positive button on the top.  Flat top batteries will not work. Installing magnet(s) on top of your battery is very dangerous and will void the warranty.

Provari_onoffOn/Off Mode
You can put the ProVari in standby mode so it will not turn on the atomizer when the button is pressed. This safety feature prevents the atomizer from turning on while it's in your pocket or bag and it prevents any settings from getting changed without you knowing.

 

ProVari_stopwatch16 Second Cutoff
If the button is held down for 16 seconds or longer, the ProVari will shut itself off until the button is released. If you forget to turn it off before storing it in your pocket or bag, this protects you and prevents the device from activating.

 

ProVari_shortShort Circuit/Atomizer Protection
This protects the ProVari against shorted atomizers/cartomizers.  If this error occurs the ProVari will alert you by displaying E1 on the digital display.  Fix: Remove the atomizer or cartomizer and replace with a different one.

 

ProVari_batt2Reverse Battery Protection
Protects against reverse battery installation.

 

 

ProVari_lowbattBattery Monitoring/Over-Discharge Protection
The ProVari monitors the battery voltage and will automatically turn off when the battery is discharged.

 

ProVari_amperageAmperage Limiting to 3.5 amps
The ProVari will monitor and shut itself off if it detects any excessive over-current conditions. If this error occurs the ProVari will alert you by displaying E2 on the digital display. Fix: Lower your voltage setting.

 

ProVari_thermThermal Monitoring
Shuts the device off if it detects a high temperature condition.  Once the device cools off, it will resume normal operation. If this error occurs the ProVari will alert you by displaying E3 on the digital display.
Fix: Let the device cool off for several minutes before using again.
(This is a very rare event and something you will most likely never see.)

 

How can the ProVari take a 3.7V Battery and bump it up to 6.0V?

The ProVari uses a special circuit called a Boost Circuit. This technology has been around for many years and is very reliable. This same technology is also used in the new hybrid electric Toyota Prius™ vehicles.

The boost circuit is capable of increasing the voltage from 3.7 to a higher setting of your choice and it does it very efficiently.

Most variable voltage devices on the market use a linear regulator which are only about 50% efficient. The ProVari is 95% efficient. This means longer run times and on a single battery. Single battery devices are the safest you can own!

What is the difference between regular and high drain batteries and why do you recommend I use the high drain over a standard 18500/18650 battery?

We recommend only using the IMR High Drain battery in the ProVari. These special batteries are rated to have a higher power output than non-IMR batteries. Non-IMR batteries can't flow enough energy for the conversion circuitry in the ProVari.

You can use non-IMR batteries in the ProVari, but since the conversion circuitry might become power starved, it might think it's dealing with a dying battery and turn off. The unit was designed to use the high drain batteries and we recommend using these for best performance.

What kind of charger do I need for the AW High Drain Batteries?

Any charger that can accept the 18500 or 18650 batteries will work.

The most common chargers are the TR-001 which has the spring loaded legs that extend when you insert the battery. These chargers are ideal. If you need to get a charger, we offer one on the Charger page.

If I want to convert the 510 to a 901 or 801 do I need a special adapter?

The ProVari has a standard 510 atomizer adapter and any of the mini adapters that we offer will work.

Does the ProVari need maintenance?

No, it's maintenance free. The only thing we suggest is that you clean the excess juice out of the reservoir and clean the metal contacts down inside the atomizer adapter once a week. You can use a Q-tip or paper towel to clean off the parts.

Does the ProVari use PWM? (pulse-width modulation)

Yes, the ProVari is using the PWM pulse-width modulation technology.

What happens when there is a shorted atomizer and how do I clear it?

Anytime there is a shorted atomizer condition, the ProVari will turn off and the digital display will show you an error message (E1) for 4 seconds.

As soon as you replace the atomizer and press the button again, the device will automatically reset and you can begin using the ProVari again. There is no need to reset the device and it's always monitoring for a short and it will clear itself once you install a new atomizer.

Can I order the ProVari without the 18500 battery cap. I only want to use the 18650 cap?

At this time all devices come standard with the 18500 battery cap and you purchase the 18650 cap separate. This gives you more options and a backup end cap.

Is there a preferred atomizer to use with the ProVari?

Yes, we recommend using a higher resistance atomizer. This will give you the most voltage options. For Cartomizers we prefer the 3.0ohm and for Atomizers High Voltage 2.8-3.2 ohm work best.

Low Resistance - Low resistance atomizers/cartomizers are not the best to use, they will limit the voltage options that you can go up to. Also note that as a atomizer heats up, their resistance drops. When they get dry the resistance also drops. If you have your voltage set higher and the resistance drops, it will cause the E1,E2 errors.
When using a higher resistance atomizer you will be able to dial up the voltage into the higher ranges and have more room for the atomizer resistance to move around without getting into the limits of the device or driving the atomizer into a very low range or short.

Tips for Ego Tanks

If you don't fully snap the cap on after filling or if you don't make the tank fully seat in the atomizer, some leaks can occur.

1 - Pre-puncture the empty tank and remove the chad.

2. Wipe the tank down before inserting it.

3. Insert the tank slowly.

We suggest you insert the tank cartridges into the eGo-T atomizer vertically, the tank cartridges up, eGo-T atomizer down.

Sometimes the pressure system created by inserting the tank can blow the wicking out of the spike down inside the ego atty. This may require you adjust the wick.

Adjusting your Ego adapter if its not working

1. Screw the eGo adapter onto the ProVari

2. Turn the slotted center section (post) out (counter clockwise) with a small flat tip screw driver, so it will come into contact with the atomizer.

Screwing the adapter onto the ProVari first will keep the other side of the center section from turning while making the adjustment.

This should allow you to adjust the adapter so it works with your Ego-T atomizers.
This is for older Ego adapters. The new Ego adapter's that we manufacture don't need any adjustments.

Why does the ProVari need to use high drain batteries?

The ProVari uses an internal DC/DC converter that continuously monitors the output to the atomizer load and maintains a constant voltage with an output current limit of 2.5 amps ( each unit is tested to this limit in production, most exceed this limit by .1 to .2 amps). This output voltage is usually higher than the input battery voltage, depending on what the ProVari is adjusted to.

Battery output current is NOT the same as ProVari output current.

Here is an example that shows why. When the ProVari is putting out 5.0 volts at 2.5 amps into an atomizer load, that calculates to be 12.5 watts.

That means the battery has to supply 12.5 watts to the ProVari, at a minimum. In reality it is more because nothing is 100% efficient.

If the battery voltage is 3.7 volts it will need to supply 12.5 watts / 3.7 volts or 3.378 amps minimum. Because nothing is 100% efficient, let's add that in. Most ProVari devices are 90% to 95% efficient. Picking the worst case, 90%, the battery current must now need to be 3.378 amps/ .9 = 3.75 amps. That is a more realistic current draw, but it could be even higher.

WHY?

Let's take a look at what happens when the battery voltage droops lower than 3.7 volts. At 3.5 volts the battery current goes up to 3.968 amps.

But it can be even higher still when the battery droops to near end of charge, say 3.2 volts. The battery output current now goes to 4.34 amps. And we have to keep in mind that this is ONLY the average current. Because the ProVari converter is a pulsing device, the pulsed battery current can be a factor of 2 higher than the average current.

The battery needs to supply pulsed currents of over 8 amps. These engineering calculations show why you need a high quality, Low Internal resistance battery to supply what the ProVari converter needs.

Where does the internal resistance come into play? According to ohms law, when you are drawing 1 amp out of the battery , the battery voltage will droop .1 volts for every .1 ohms of battery internal resistance.

At 4 amps this means the battery voltage is no longer 3.7 volts but 3.3 volts.

If it won't match up to the demands of the converter in the ProVari , We won't sell it. This is why we recommend using AW red high drain batteries only!.

They have passed all our tests and are rated to work with the full range of voltages that the ProVari can offer.

Why do the cheap batteries work at all?

They work when the output is not adjusted to supply high power. They 'get by' running at low power but the full capacity of the battery is never available because of the voltage droop. This is due to the higher internal resistance causing them to shut down early. To avoid problems, only use the approved batteries that we recommend.

Are Li-ion Batteries Safe and which ones should I use?

The amount of power required to run an eCig requires a battery that can store a large amount of energy and deliver that energy on demand rapidly. Because of this requirement lithium ion batteries are the best choice. We all need to respect the amount of energy in these batteries.

But are they safe?

We all hear about the occasional incident where a battery fails in a violent way. This is caused by a short circuit within the cell or if stacked cells are used, one cell can discharge into the other with high discharge rates when one cell depletes its energy before the other.

A mild short will only cause an elevated self-discharge. Little heat is generated because the discharging energy is very low.
If, however, for whatever reason any of the following conditions happens;

1. Internal short circuit
2. Excess external charge current
3. Excess external discharge current
4. Environment conditions

The temperature can rise to the point where thermal runaway can happen that results in 'venting with flame.'
There are two basic types of lithium-ion chemistries: cobalt and manganese (spinel). Typical battery chemistry mixes are cobalt, nickel, manganese and iron phosphate.

Lithium-ion cells with cobalt cathodes should never rise above 130°C (265°F). At 150°C (302°F) the cell becomes thermally unstable, a condition that can lead to a thermal runaway in which flaming gases are vented. To achieve maximum runtime, cell phones, digital cameras and laptops use cobalt-based lithium-ion. Because of the lower temperature whereby the cell becomes thermally unstable, electronic protection circuits are added.

Manganese is the newer of the two chemistries and offers superior thermal stability. It can sustain temperatures of up to 250°C (482°F) before becoming unstable. In addition, manganese has a very low internal resistance and can deliver high current on demand. It is these two features that make this battery the best choice for use in the ProVari. The drawback of spinel is lower energy density. Typically, a cell made of a pure manganese cathode provides only about half the capacity of cobalt. The higher inherent safety of the spinel system permits the exclusion of the electric circuit in the battery. In the ProVape eCigs we incorporate the protection circuit into the eCig thus providing an added layer of safety. We know of NO safer combination then to use the manganese lithium ion battery with the ProVape eCig.

The AW IMR type cells that we carry use the manganese chemistry and are the safest of the lithium chemistry types.

The higher capacity cells use the cobalt chemistry with the electronic protection circuit.

The ultimate in safety is to have multiple redundant safety layers whereby if one layer of safety fails the other layer prevents an unsafe condition. This is what we strive for at ProVape, even if it means more internal components with its associated higher cost.

Asia produces many non-brand replacement batteries that are popular with users because of low price. Many of these batteries don't provide the same high safety standard as the main brand equivalent. A wise shopper spends a little more and buys a higher quality battery with its higher level of safety.

It is NOT recommended you use an unidentified lithium-ion battery from an Asian source.

As a consumer, you are in a position to select the highest quality and safest equipment. With each purchase, ask yourself,”Are a few pennies or dollars saved worth the safety risk?” Ultimately, your personal safety is in your hands with the equipment you buy.

Today, lithium-ion is one of the most successful and safe battery chemistries available. Two billion cells are produced every year. But be aware that there are several lithium ion battery chemistries being sold in the market. Some are safer than others.

Considering the number of lithium-ion batteries used on the market, this energy storage system has caused little harm in terms of damage and personal injury. In spite of the good record, its safety is a hot topic that gets high media attention whenever an incident occurs.

My LED is flashing rapidly like its out of power but my battery is fully charged. What should I do?

There are a couple of things that can cause this to happen.

1. If any of the contacts are dirty and the battery is not able to supply enough power because of a weak connection it can cause the light to flash rapidly. Its best to clean the tops of your batteries often and once a week clean the contact down inside the ProVari. You can clean the small metal contact inside that the battery positive touches with a long Q-Tip and some isopropyl. Rub the pin for a good 20-30 seconds to make sure you get any dirt and grime off and you can also use the isopropyl on the battery tops and bottoms to get them nice and clean.

2. Make sure you are using the correct battery. The AW high drain red battery is the one we recommend because it has a high output capacity and a low internal resistance. All protected batteries like the trustfire cells and other brands have a protection circuit that limits the output of the battery which can cause issues. If you are already using the AW batteries, try cleaning all the contact points and see if that helps. Make sure you are not using old batteries. Rechargeable batteries should be replaced every three months as they wear out.
