Is vaping better than smoking?

My answer to Is vaping better than smoking?

Answer by Allen He:

"E-cigarettes either do not contain or have lower levels of several tobacco-derived harmful and potentially harmful constituents compared with cigarettes and smokeless tobacco… [e-cigarettes] present an opportunity for harm reduction if smokers use them as substitutes for cigarettes."

Vaping vs Smoking – A Head-to-Head Comparison on all Fronts

Health and Safety

Vaping is still dangerous, and many vaporizers employ a liquid known as e-liquid or e-juice that contains nicotine, but usually not in the high concentrations that represent in cigarettes. The biggest change in safety comes from the way the product is produced and delivered. In smoking, the contents (usually tobacco and about 4,000 other ingredients) are combusted. They are lit and they burn and the smoke is inhaled by the user.

This also creates secondhand smoke which causes numerous health problems on its own. Overall, it is a very unhealthy situation, and that combustion creates a lot of the carcinogens present in cigarette smoke.

In vaping you usually don’t have that. You have to say “usually” because not all vaporizers manage to heat their product without combusting it. But once you eliminate the combustion, you do make the product safer. Instead of smoke, you would be inhaling vapor or steam. It’s likely much safer, but you are still inhaling a lot of chemicals that aren’t very good for you.


Cigarettes are pretty much everywhere. You can find them at the grocery, the gas station, online and in many of the shops you frequent. They have been a part of public use for so long that most people just accept that they are there.

Vaporizers are a little harder to come by. Back in the olden days of vaporizer sales, you could only find them in mall kiosks and mail-order catalogs. Now they have a huge presence online, and you can even find them in some markets and many tobacco and vaporizer specialty stores.

But you will have a much harder time finding vaporizers and their assorted product lines than you would find cigarettes and smoking paraphernalia. As vaping becomes more popular, it is increasingly easy to find them.

Legal Status

Here is where the debate between the two really heats up. Cigarettes have been banned in some form or another ever since they appeared. They were first banned on airlines, then in government buildings and later in pretty much every public location. Some states have looser restrictions than others, but for the most part, if you are in a public space, you either have to find a designated smoking area or just wait to smoke until you get home.

Vaping is a bit more complex, but it is slowly going the way of cigarettes as far as public tolerance. While those who vape claim that the secondhand vapor is not as dangerous as secondhand smoke, the research behind such claims is not conclusive. The public often perceives vaping as the same thing. It appears like smoke is emanating from the vaporizers, so non-smokers feel like they may be in danger while vaporizers are in use around them.

What this has meant for those who vape is that the use of vaporizers is slowly being outlawed in public places, city by city. These bans don’t seem to ever lift, so unless new research is discovered it is likely that the bans will continue until vaping is just as prohibited a smoking is.

Cost Effectiveness

When we compare smoking vs vaping in terms of cash you have to spend, vaping comes out as a clear winner. Although there are many cheaper options, the very best, high-end vaporizers can cost somewhere around $250. After that, all you need to buy is your favorite e-liquid, and almost all e-liquids come at a nominal cost. As for cigarettes, let’s suppose you’re a pack-a-day smoker, your monthly cost will be somewhere around $300 depending on where you live. So, in the long run, you’ll be saving big bucks by switching to vaping.

What’s the best way to control vaping?

My answer to What's the best way to control vaping?

Answer by Allen He:

Hey, i recommend you a site:How to Quit Smoking and Using Tobacco. Hope this is helpful:

Many treatments and resources can help you stop using tobacco, including medications and counseling. But the first step in quitting is to commit to quit. Then, you need to set a plan. Having a plan increases your chances of quitting successfully. A strong plan will include:

  • A quit date
  • Plans for dealing with situations that make you to want to smoke or use tobacco
  • A support network

Talk with your doctor about putting together a treatment plan to help you quit. Remember, it may take several attempts to successfully quit tobacco use. Don’t give up.


Using medication can at least double your chances of quitting smoking. The U.S. Food and Drug Administration (FDA) has approved several medications to treat nicotine addiction. If you have health insurance, medications to help you quit tobacco use may be covered.

Nicotine replacement therapy (NRT). NRT is the most widely used medication for quitting. It has mild side effects and is available over the counter and by prescription. NRT lessens the symptoms of nicotine withdrawal and cravings. Your doctor will help find the best dose for you based on your current smoking habits. NRT comes in several forms:

  • Gum
  • Lozenges
  • Skin patches
  • Inhalers
  • Nasal sprays

Bupropion (Wellbutrin, Zyban). This medication can reduce withdrawal symptoms. Common side effects include dry mouth and difficulty falling asleep or staying asleep.

Varenicline (Chantix). This medication reduces withdrawal symptoms and keeps you from enjoying nicotine if you start smoking again. Common side effects include nausea, vivid dreams, constipation, and drowsiness.


In addition to medication, counseling can be used to help with stopping tobacco use. Counseling increases your chances of successfully quitting. Your doctor can refer you to a professionally trained counselor or mental health therapist. A counselor can help you set up a tobacco-free environment and change behaviors and identify triggers that make you want to use tobacco. It is helpful for people who:

  • Have tried several times to quit but have not been successful
  • Experience severe feelings of anxiety or depression
  • Do not have enough support from family and friends to quit
  • Are dependent on alcohol or other substances

Medicare, Medicaid, and private insurers cover different types of tobacco-quitting programs and offer different coverage levels. Talk with a nurse, social worker, or other member of your health care team to learn what may be covered through your insurance policy. If you do not have insurance, these people can help you explore other options.

Mobile apps

If you want a little extra help in stopping your tobacco use, you can try using a mobile app for your smartphone, laptop, or other mobile device. Studies have shown that using app like this can help motivate you to reach your goal. There are a lot of apps available, but only some of them offer reliable, science-based support. Some apps actively try to encourage people to smoke more! Be sure to choose apps carefully, and when in doubt, ask your health care team for guidance. A list of a few mobile apps is located in the Resources to Help You Quit section.

Electronic cigarettes and other forms of tobacco

Some people think that switching to smoking electronic cigarettes will help them quit smoking tobacco cigarettes. Electronic cigarettes are also known as e-cigarettes and vapor cigarettes. E-cigarettes vaporize a nicotine fluid, which mimics the smoke that comes from burning tobacco in traditional cigarettes. This is why some people refer to using e-cigarettes as “vaping.”

E-cigarettes are a relatively new product, and the market is changing rapidly. There are thousands of e-cigarette devices and liquids available. E-cigarettes are currently not regulated by the FDA. There are also no regulations or quality controls guiding the manufacturing of the devices. The FDA does not approve their use as a way of quitting smoking. In 2015, ASCO and the American Association for Cancer Research (AACR) issued a joint statement on electronic nicotine delivery systems or ENDS. ASCO and AACR agree that there is not enough scientific research to say that this is a safe and effective way to quit tobacco use and do not endorse their use as a quitting aid. More research is needed to understand if e-cigarettes can harm or improve health.

In addition to e-cigarettes, some people think about going from smoking cigarettes to smoking pipes or cigars instead. This is not an effective way to stop smoking. All forms of smoking tobacco, including pipes, cigars, and cigarillos, contain carcinogens and are not safe alternatives to cigarettes. Waterpipes, or hookahs, present the same dangers as other forms of tobacco smoking, even though the smoke is first passed through water. In fact, smoking through a waterpipe can expose you to higher amounts of toxins than smoking cigarettes.

Smokeless tobaccos, such as chewing tobacco, snuff, snus, and dissolved tobacco, are also not an effective way to stop tobacco use. Many people feel that smokeless tobacco is less dangerous than smoking cigarettes, cigars, pipes, and cigarillos. However, even smokeless tobacco products contain nicotine and other chemicals that increase the risk of cancer, particularly oral cancer.

Have realistic expectations

Different people will have different experiences with stopping tobacco use. However, it is helpful to prepare yourself for the reality of what it is like to stop using tobacco.

When you first stop, you will likely experience the symptoms of nicotine withdrawal. Common symptoms of nicotine withdrawal include:

  • Urges to smoke
  • Irritability
  • Difficulty concentrating
  • Restlessness
  • Increased appetite
  • Anxiety
  • Feeling depressed

These symptoms are usually at their strongest in the first few days after quitting. About 1 to 2 weeks after stopping, the symptoms will usually lessen. However, if you have a strong addiction to nicotine, these symptoms may last for weeks or months. Some people have mild withdrawal symptoms, whereas others have moderate or severe symptoms. The uncomfortable symptoms of withdrawal often draw people back to tobacco use. Even many years after successfully quitting tobacco use, people have gone back to a smoking habit because they’ve been exposed to other people smoking. Overcoming a nicotine addiction can be a life-long process. Do not be afraid to ask for help and support coping with the symptoms of nicotine withdrawal.

Is vaping bad for your health?

My answer to Is vaping bad for your health?

Answer by Allen He:

We know tobacco kills, and e-cigarettes, at least, seem to help people quit.

Research has indicated that e-cigarettes help people slow their tobacco consumption, anOctober 2014 study showed that six months of vaping led 21 percent of participants to quit traditional cigarettes, with an additional 23 percent cutting back by half.

And according to a new British survey of 1,800 people, e-cigs are replacing approved aids for quitting tobacco, too. They are now used roughly twice as often as government-regulated nicotine gums, lozenges, and patches across the pond. (Similar data does not yet exist for U.S. consumers.)

Meanwhile, the California Department of Public Health just declared e-cigarettes a public health threat.

The week before last, a study claimed hidden high levels of the carcinogen formaldehyde were found in e-cigs, potentially increasing lifetime cancer risk by 5 to 15 percent.

The American Lung Association has also stated its fear of the “potential health consequences” associated with the use of unregulated e-cigarettes — with almost 500 different brands, 7,700 different flavors and wide-ranging nicotine levels. ‘There is much to be concerned about, especially in the absence of FDA oversight,” the organization said in a statement.

When it comes to e-cigarettes, there are those who argue for the pros and there are those who voice the cons. There are no clear answers, leading new U.S. Surgeon General Dr. Vivek Murthy to call for more guidance on e-cigarettes use as an aid for smoking cessation.

“There’ve been theories and ideas around the fact that e-cigarettes may be helpful from a harm-reduction perspective in helping people who are already on cigarettes [and who] have had trouble quitting actually get off cigarettes,” Murthy said on Tuesday, Jan. 27 in Richmond, Va., as part of a cross-country listening tour. “If the data indeed bears that out, then I think we should absolutely embrace that and use e-cigarettes in targeted ways.”

However, don’t mistake Murthy’s words for a wholehearted endorsement. “I’m concerned about e-cigarettes, and I think this is an area where we are in desperate need of clarity,” Murthy said. “I think it’s important for us to understand the impact, particularly on youth, before we allow the full-fledged spread of these e-cigarettes and then later have problems that we have to deal with.”

What are those problems? Let’s take a look at the pros, the cons, and exactly what we do and don’t know.

The Good

As previously mentioned, e-cigarettes aren’t all bad. They do seem to help people who are trying to quit traditional cigarettes curb their tobacco addiction, leading the surgeon general to say we could potentially use these devices in “targeted ways.”

According to a 2013 study of 657 smokers published in the Journal of the American Medical Association, e-cigarettes were as effective as nicotine patches in helping people kick their tobacco habit for at least six months.

According to Charles Powell, MD, chief of pulmonary medicine at Mount Sinai Hospital and a professor of medicine at Mount Sinai Medical School in New York City. “they are essentially a delivery device for nicotine,” he tells Yahoo Health. “Just like gum or patches, they have similar replacement effects, and they’re potentially a more comfortable, attractive way to deliver the substance.”

Is there power bank for laptop?

My answer to Is there power bank for laptop?

Answer by Allen He:

Is There A Power Bank For Laptop? Many people will ask this question. We usually use power bank to charger our smartphone ,tablet , Go-pro or other smart devices. But we seldom or never see people use power bank to charger laptop. So the question is "Can we charge laptops via USB with a power bank?

PLUG – The World's Most Powerful Battery Pack

With PLUG you can live life on your terms. Imagine working from the beach without having to rely on your laptop battery. How about taking a family camping trip with the convenience of electricity at your campsite? Or being able to capture those special moments in perfect clarity because you can now use studio lighting anywhere. PLUG makes all of these situations and many more a reality.

And hey! Since it has two outlets, why not share the power with a friend?


Yes, The answer is positive. The power bank capable to charge a laptop needs to supply not only the USB standard charging port but also (or only) a DC output port, or a build-in power inverter with an AC outlet. Usually they have in their name a “multi-voltage portable charger”. I will say if the portable power bank can charger for Surface 3 Pro, most of them are capable to power (recharge) a laptop battery as well. Here are some samples: Surface Pro 3 External Battery – Options And Accessories, Extend Your Surface Pro 3 Battery Life

There are power banks available with various plug in connectors for laptops, but they cost around 15,000. I have seen one on ebay india, and the ad says that they’ve even sold 29 units. These are not marketed by laptop manufacturers so I am not sure what your laptop warranty status will be if you purchase one of these banks and use it charge your laptop. Most laptops charges through its adapter only. Powerbanks on the other hand have only usb 2 output interface. Replacing laptop batteries with Extra cell batteries available in the market can help. One desi jugaad is using a UPS to charge a lappy but it wont make it handy and portable.

How do I repair a Samsung phone dropped in water?

My answer to How do I repair a Samsung phone dropped in water?

Answer by Allen He:

Take your phone out of the water!

Remove your phone from the water or liquid as quickly as possible if you have not done so already.

Don’t Press Anything

Resist the urge to see if it’s still working:

  • Don’t turn it on
  • Don’t navigate
  • Don’t press any keys
  • Don’t use the phone

Remove the battery

If your phone will allow you to then remove the battery, and cut all the power to the device to decrease the chance of a short.

Remove it from its case

If you keep your phone in a protective case then dry the outside of the case and then remove it. Try not to rock the phone to much to help prevent water from running into any of the phones ports, plugs, holes, cracks or spread further throughout the inside of the phone.

Take off the removable parts

If your phone has a SIM card or Memory card then take it out and if necessary set it aside to try as well. SIMs are replaceable if needs be and most memory cards (at least the best memory cards) are waterproof.

But take them out of the phone and leave the battery cover or back plate off to help with the drying process and allow those parts of your phone to vent.

Dry the phone with a dry towel or cloth

Dry the outside and any visible areas with a dry cloth or towel. Again take caution not to let any water into the openings of your device if possible.

DO NOT Blow it

I do NOT recommend air in a can, a blow dryer, or even blowing air through your lips or a straw.

You might cause heat damage with a blow dryer or adversely blow water into the phone or blow the water around that’s already into the phone and cause more damage.

Do not take the phone apart

Don’t unscrew the phone or try and open it to get access to the inside of the phone. Even though the LDI (Liquid Damage Indicator) on your phone was most likely activated voiding your warranty, taking the phone apart could void your warranty 100%. So I don’t recommend it except as a last resort.

Dry the phone

You dried the outside and visible moisture as best as you could with a dry towel but now we have to dry the moisture that you couldn’t get to.

  • Use a Vacuum – although blowing the water on the phone is a bad idea, sucking the water off and or out of the phone might not be. Just make sure that you use caution trying not to scratch the phone or create a static charge from the vacuum.
  • Use Rice – One of the most common tools for drying phones is uncooked rice. Get an airtightcontainer or zip lock bag and bury your phone in rice. The rice will absorb the moisture and help dry out our phone.
  • Silica Gel Packs – If you have any of these cool packets lying around (they are the gel packs you can find in shoeboxes) then these are great at absorbing moisture because that’s what they are meant to do. Place some packets into an airtight container with your phone and wait for them to help dry it out completely. Note: old packets that have already been used will have already reached their absorption capacity and won’t work.
  • Phone Drying Pouch – If you planned ahead and bought a phone drying pouch for just this situation then locate it and use it to assist you in drying the phone. If you don’t have one of these nifty packets then you can plan ahead for any future incidents and buy one for next time. These packets are often sold by stores as well (including Wal-Mart) if you want to check online to see if they have any in stock or place your phone in rice in the meantime and then run down to the store and see if you can locate one.

Wait for 24-48 hours

Wait for the moisture in the phone to dry out completely. If you have another phone that’s the same carrier as your current one you might be able to use that device while your primary phone dries. If your phone uses a SIM card then make sure your SIM is dry and insert it into another phone of the same wireless provider. Or simply take a break from your texting, tweeting, and networking and read a book or browse this awesome website instead /wink.

Check the phone

After a day or two of allowing the phone to dry check for moisture that might still be in or on the device. If moisture remains evident then do not re-insert the battery or accessories just yet. Continue the drying process with the suggestions above again until the phone is completely liquid and moisture free.

Attempt to power it on

Try and turn your phone on listening for any irregular noises and listening to make sure that the speakers still work on the unit. Check the screen and make sure that it appears to be working properly visually and if your phone has a touch screen make sure to check the touch screen to make sure that it too is responding correctly.

If your phone does not power on

If there is no response when attempting to power the phone on then plug your phone into a charger and see if you can get a response from the charger. This will help you to see if perhaps the battery was damaged or if it’s the phone itself.

If you a friend or a family member has a battery of the same type you can try that as well.

Addition things NOT to do to a wet phone

  • Freeze your phone – I don’t recommend that you put your phone in the freezer for many reasons. The chance of it causing additional damage is high because of many different factors.
  • Use an oven or microwave – don’t use an oven or microwave to help dry out your phone.
  • Apply heat – Applying heat from an external source will likely cause more damage to your phone. This could also cause your lithium ion battery to explode or start to leak, so don’t try it on your battery either.
  • Tap or bang your device – If your device isn’t working after drying it then read the article mentioned at the bottom of this article. DO NOT bang your phone against a hard surface to try and get it to work again. Along with liquid damage you might add some physical damage as well and it will be even more difficult to fix.

More Tips

If your phone was submerged at the beach and the salt water has gotten into it OR at a pool and has been exposed to water with chlorine in it then your phone might have a higher chance of being damaged or malfunctioning and you might also consider worrying about, minerals, possible corrosion or even calcium buildup forming and causing additional damage.

Some people recommend submerging your phone in clean water to remove the salt/minerals/chlorine water but I don’t recommend that because water, as you know, is a conductor and clean water can lead to a short, corrosion or calcium buildup just as well. Read the article mentioned below for some tips on fighting these forms of water damage.

Still not working properly

If your concerned with corrosion, calcium buildup or other damage, or your phone is simply not working properly even after drying completely, then I strongly suggest that you read How to fix a water damaged phone for some tips on how to get your phone working properly again.

Fixed and working correctly

If your phone is up and running again then make sure everything is working properly, keep an eye on the functionality of your device and enjoy the continued use of your phone. I hope you enjoyed the article. If you have any other tips or tricks then don’t hesitate to leave a comment below.

With a 10400 mAh Xiaomi PowerBank, how many times will I charge my samsung A5?

My answer to With a 10400 mAh Xiaomi PowerBank, how many times will I charge my samsung A5?

Answer by Allen He:

2300 mAh battery

How many times can a 10400mAh power bank fully charge your samsung A5? Actually, this is a difficult question to answer.

The number of times a 104000mAh power bank can fully charge your device is relevant top 3 primary factors.

1.— What device you are charging with a 10400mAh power bank —

Generally speaking, a good rule of thumb is to divide the mAh of 10400mAh power bank by the mAh of your device battery.

So a 10400 mAh power bank can “theoretically” charge an samsung A5 from 1-100% 2.7 times (10400 / 2300 = 4.5). –iPhone battery capacity is 1810mAh

Keep in mind: this is never 100% accurate as there still some other factors involved which will influence the charging times, which is always higher than what a 5000mAh power bank can practically give. Keep reading…

2.— What is the device doing while it is being charged —

It’s not strange to see the device charged, for example, by a 10400mAh power bank, while you’re still using the device. So is there any difference between using the device while it’s plugged into and leaving the device alone or on airplane mode while it’s charged? The answer is undoubtedly YES.

If you are watching a movie on your device while the 10400mAh power bank is charging it, more power drained from the 10400mAh power bank and meantime it seems that your device is never charged. That is because you’re taking the power more quickly than the 10400mAh charges your device.

If you leave your device alone or on airplane mode while charging, you will get more fully charges since the device is not taking much battery charge at all while the 10400 mAh power bank is charging up the device.

3.— The charging cycles of the power bank 10400mAh —

More charging cycles the power bank gives, its capacity will reduce. Theoretically, the capacity will reduce to 80% after 300 charging cycles. If so, a 10400mAh power bank may have a 8320 mAh capacity. This is also relevant to the temperature when you’re using your power bank. And this point I believe you could find out on the manual when you brought the power bank.

4.— Both the calculation we mentioned above i think are right.


The power of 38.48KWh keeps unchanged when power bank output raise to 5V.


so 7696mAh/1810mAh = 4.2 times

The second one we usually we need multiply a transfer rate of the power bank capacity. usually 10400mah power bank will get only 10400mah * 0.8%=8320mah or so capacity in real.

8320mAh/2300mAh = 3.6 times


5000mAh rated power bank charge an iPhone 6 2 times

5.—Other Tips: As you can see, this is a very difficult question to answer. But I hopefully the information given here will be helpful. And welcome all to comment below or share to Facebook and twitter for more charging tips about samsung A5.

Why are Samsung phones catching fire?

My answer to Why are Samsung phones catching fire?

Answer by Allen He:

The explosion was triggered by the battery heating and fire while charging, according to the description of the victim of Galaxy Note 7 battery explosion, the charger and charging cable he used were not genuine, he applied an old Type-C adaptor which was connected with an unbranded cable, some bloggers deduced a conclusion that unmatched charger and cable caused Galaxy Note 7 battery explosion, hence, charging with original Samsung charger and cable is highly recommended.

Is that all? Probably not. Citing an unnamed company official, it is said that Samsung’s investigation found that faulty batteries caused the phone to catch fire. The number of the Galaxy Note 7 phones with a faulty battery accounts for “less than 0.1 percent” of the products in the market. Some shipments are being delayed due to additional tests being conducted for product quality. People started to worry that the Galaxy Note 7 on hand hit that 0.1 percent.

Samsung officials did not reply to questions about how Samsung determined which phones are deemed safe and which require further testing. It did not say if those phones are different from the ones sold in South Korea. As the latest iteration product of Samsung, several Galaxy Note 7 battery explosion cases happened within such a short period after the launch, it created a perfect chance for the upcoming iPhone 7 to take the lead again.
