High Wattage Mods: will Your Device actually Deliver?
Over the past year, we’ve seen an inflow of high power mods hit the market. There was a time when twenty or thirty watts was additional than enough power for many vapers, but with the origin of sub-ohm vaping and quality of cloud chasing, there is a growing need for higher power devices. Manufacturers ar building mods that vary anyplace from one hundred to two hundred watts, and in some cases even higher.
Now you’re in all probability speculative, do these devices really push as a lot of power as they claim?
Let’s find out.
Getting two hundred Watts From a Regulated Device
Most manufacturers of high power devices (above 150+ watts) misrepresent however several watts their devices will truly smoke water pipe. A regulated mod is limited by each the chipset and therefore the battery.
Serial vs. Parallel Battery Configuration
There are 2 totally different ways that that batteries will be connected; parallel and serial. Parallel batteries are connected aspect by aspect, while series batteries ar connected as if they were stacked on prime of every alternative.
Serial configuration treats the batteries as if it’s one battery, although it combines the voltage that the batteries ar ready to output. Two twenty amp batteries in series configuration will output eight.4 volts, but will solely handle a most of twenty amps. To reach 200 watts on eight.4 volts would draw twenty three.8 amps from your batteries.
Parallel configuration willn’t combine the voltage like it does with the amp limit. Two twenty amp batteries in a parallel configuration will solely output four.2 volts, but they will handle a most of forty amps. Reaching 200 watts on four.2 volts would basically draw forty seven.6 amps from your batteries.
In either type of configuration, you cannot safely draw enough amps from two batteries to succeed in two hundred watts.
Some people argue that as a result of we tend to pulse our batteries once vaping, (as opposed to an eternal draw) we ar among the bounds of our best vape. Be that as it may, this is not generally thought-about to be safe. In fact, pushing batteries to the limits of their ratings can harm the cell over time, and ultimately lead to failure.
The Limitations of Your Batteries
Your vaporizer can solely draw a restricted quantity of power out of the batteries that ar put in within of it. One battery can hold a most of four.2 volts. When you use 2 batteries, that number is doubled, but solely once they're during a series configuration, giving you the power to push 8.4 volts. A chipset can conjointly store further volts.
Using associate degree Ohm’s Law calculator, below are the results of reaching two hundred watts:
● Voltage: 4.2
● Resistance: 0.09
● Amp Draw: 47.62
The first factor you’ll notice is that your batteries got to be absolutely charged. They won’t remain at four.2 volts for longer than 5-10 puffs at two hundred watts, so your power can decrease considerably as the batteries ar drained.
Secondly, the resistance of your atomizer desires to be at zero.09 or below. The majority of regulated devices fail to fireside atomizers built at this low of a resistance.
Lastly, the amp draw is at 47 amps. The best batteries on the market can handle between twenty to thirty amps. Other batteries ar rated as low as ten amps, despite what its label says (there are conjointly several fakes). Some manufacturers can even claim their batteries will sustain sixty amps, however tests show that there ar no batteries on top of 30A continuous. As a result, we don’t apprehend however safe some batteries actually ar unless you’re shopping for from a sure and honorable manufacturer. To pull 47 amps out of 2 batteries is risky, especially if you aren’t fully certain of the specs of your battery.
Battery Sag
The more amps you draw from the battery, the more the battery can suffer from battery sag. This is a short lived dip in voltage that happens to any battery while it's underneath load (when you’re firing it). Some batteries have less sag than others vape. This is partially owing to the age and therefore the quality of the battery. High-performance batteries ar your best bet for the least quantity of sag.
Due to battery sag, even a fully charged four.2-volt battery will not output a full four.2 volts. Some batteries might see a reduction of over one whole V whereas it’s underneath load. You’re likely to see even additional sag once drawing high amps for an occasional resistance load. Less volts equals less wattage.
The Limitations of Your Device
The computer chip within your device will draw further power, but solely to the purpose wherever it’s still safe for your batteries. Most of the boards installed in high-wattage devices deliver a scoop output voltage of seven to ten volts. Upwards of 8.4 volts needs pulse-width modulation (read additional concerning that below).
For example, let’s say that your vaporizer limits maximum output voltage to eight volts. In order to induce to 200 watts from eight volts would need twenty five amps drawn from your batteries. Drawing that many amps would end in a colossal decrease in voltage. The safety protections built into regulated mods can typically not enable you to fireside the device if the battery charge drops below three.2 volts every.
Pulse-Width Modulation (PWM)
Manufacturers will any increase voltage by mistreatment pulse-width modulation that takes place once combining capacitors reach a planned level and discharge back into the circuit. Although not continuous, the additional charge acts like an additional battery. You will not get a full two hundred watts whereas you vape, but could attain your desired power in brief bursts.
Can You Pull two hundred Watts with associate degree Unregulated Device?
Unregulated devices don’t bear any electrical components. A user has no restrictions from pulling as several watts as they wish from their batteries, making unregulated devices very dangerous for folks while not expertise and data of battery safety and Ohm’s Law. Batteries can solely take therefore a lot of stress and if the restrictions ar pushed, the batteries can vent and even explode.
With proper care, unregulated devices can be absolutely safe {for experienced|for dataable|for skilled} vapers UN agency have the knowledge and ability. The rule of thumb is don’t pull more amps than your batteries will handle.
Sure, you can technically pull two hundred watts or additional from associate degree unregulated device, but your batteries can not be able to handle the strain for long. Use an Ohm’s Law calculator to create certain you’re building safely.
Note: ALL safety precautions mentioned above apply for unregulated devices as well
Don’t Let Your Screen Fool You
Just as a result of the screen on your device says two hundred watts doesn’t mean you're truly touching two hundred watts, at least not out of a dual-battery setup.
Theoretically, you can get two hundred watts out of 2 batteries. By using pulse-width modulation, fully charged batteries, batteries with zero inefficiencies, efficient chipsets, and batteries with minimal voltage sag, you can seemingly reach two hundred watts some times before the battery loses its charge, but smart luck obtaining all of those variables to return along at once!
It’s very seemingly to safely reach some a hundred and forty watts with 2 absolutely charged batteries. With pulse-width modulation you can get higher power for brief bursts and solely till the battery charge drops, which could be simply some puffs.
The bottom line is you'll be able to expect accurate readings from dual-battery devices that push but one hundred twenty five watts. Any more than that's merely not safe or realistic.
