Tips When Buying a Portable Battery Pack for Your Mobile Device

Phone, Smartphones and tablets these days are effectively like pocket computers. But being multi-talented comes at a cost of considerable battery drain. Until the next battery breakthrough, most people today opt to carry an external battery pack with them. Here are some tips on how to go about choosing one; or put another way, reasons why some battery packs are more expensive than others.

#1. Capacity vs. Portability

The main spec to look out for in a portable battery pack is capacity, which is measured in mAh. The capacity of your device’s battery is also measured in mAh, so loosely speaking, if your phone has a 2,000mAh battery, a 2,000mAh battery pack is able to recharge it fully once. However, because of power lost due to voltage conversion and remember, the rated capacity is usually for 3.7V, but during charging, the output is at 5V, and sometimes, the quality of the charging cable, this is rarely the case in reality. While you can get one with a there are battery packs which go up to 20,000mAh so that it’s able to recharge a device multiple times over, keep in mind that this usually also means that it’s bigger, heavier, and pricier.

#2. Your Mobile Device’s Input Current

Most smartphone-oriented battery packs output at most 1A (at 5V) over the USB port. While this works fine for most people, some may notice that their smartphone now takes a longer time to recharge as compared to when a wall charger is used. This is especially true if the phone is able to accept a higher current. Many recent Android smartphones have a 1.5A charging interface, and those which support Qualcomm’s Quick Charge 2.0 standard (e.g. LG G2) can draw as much as 2A. So, manage your expectations.
Most tablets require at least 1A to charge too, with some drawing up to 2.5A. Take the Apple iPad Air for example, which comes with a 12W USB wall adapter that provides 2.4A. If you were to plug the iPad Air to a battery pack’s 1A USB port, it’ll either not charge or charge super slowly. So if you’re looking to charge a tablet, our advice is to buy a battery pack that’s capable of outputting higher than 1A (at least 1.5A if you’ve an Android tablet, and 2.1A if you’ve an iPad). Lastly, there’s no harm using a higher-powered port on a smartphone, as the device only draws what is required. In fact, it may even charge faster if it’s able to draw more.

#3. The Battery Pack’s Input Current

It’s easy to persuade yourself to buy a large-capacity battery pack. But one tends to forget that the higher the capacity, the longer it takes to recharge. In fact, most people we know who have 15,000mAh battery packs leave them to charge overnight. Another factor that affects how long it takes to top up the charge is the battery pack’s input current. Most battery packs accept between 0.8A and 1.5A, with the higher currents typically found on the higher capacity ones. If you come across two seemingly identically-spec’ed battery packs and both cost the same, this little detail could be the tiebreaker.
Some battery packs allow themselves to be charged while they’re charging other devices. However, we don’t recommend it because constant pass-through charging may affect the battery’s lifespan.

#4. Number of Ports

Many recent battery packs come with a built-in USB cable that wraps around the case so that you don’t need to worry about leaving the USB cable at home. To cater to iOS users, some of them come with a built-in Lightning cable instead. These Lightning connector-compatible battery packs tend to cost more than their USB counterparts because of the Made For iPhone/iPod/iPad licensing and certification program fees the manufacturers have to pay.
Higher capacity battery packs also usually come with more than one USB charging ports. Naturally, more ports cost more money, and the number of ports you should go for depends on how many devices you carry. The biggest advantage of additional ports is that you can charge more devices at the same time. The tip here is to find out the total output current of the battery pack when more than one ports are used. For example, a battery pack with two 2A/5V ports may output the 2A when only one port is used. When both ports are connected, the total output may be limited to 3A, with each port getting 1.5A. There are of course others that have a total output of 4A, but as you might expect, they usually come at a premium.

#5. Quality vs. Price

Batteries can explode, and the one measure we can take to (hopefully) prevent this is to buy from name brands or reputable vendors. To allay such fears, some battery pack makers will tell you (usually on the packaging) where they source their batteries from. So while that $10 brand-less battery pack sounds like a great deal compared to a branded one that costs three times as much, we would think twice about it, because it’s often impossible to know if it cuts any corners with the short circuit, over charging, and temperature protection mechanisms in order to achieve the low price.

So how do we choose an external battery charger, also called a power bank?

There are a few factors which are quite important upon selecting a portable charger (like RAVPOWER EXTERNAL BATTERY ). The first one is what is called size or portability: a number of of the power banks on the market are light and small enough to put in a pocket, and yet others are huge and unwieldy. Obviously, what you will choose depends on your needs. The second factor is capability or capacity. It should be noted that the power bank you choose to purchase will not match the advertised capacity on the device, as some energy can be lost by means of heat generated voltage change. Unless stated differently by the manufacturer, some 70% efficiency should be expected. Therefore, a power bank advertised for 10000 mAh may deliver only 7000 mAh power. Hence, some of the top power banks render about 90% efficiency. What is also important here is to check the phone’s specification or the battery of the tablet in order to make an estimate of the amount of full charges which can be expected.

EGO LB5302


Lots of power. The EGO LB5302 is considered very powerful (as TROY-BILT FLEX ) for a cordless leaf blower. In comparative testing it performs as well or better than some corded electric blowers, with enough air moving power -- 530 CFM of volume at speeds up to 110 MPH -- to lift and push piles of matted and damp leaves in testing by The run times are also impressive compared to other cordless -- around 20 minutes on high speed. There's an even more powerful Turbo boost feature that will eat up the battery faster, but experts such as Clint DeBoer at say that's a feature that, when used correctly, should only be used on rare occasions. On low speeds, the rechargeable 56-volt lithium-ion batteries can keep going for up to 75 minutes. The battery is compatible with all other EGO outdoor tools, a plus if you are already invested in that equipment.

Ease of use

Quiet and maneuverable. While no leaf blower is silent -- or even very quiet -- if you value peace and tranquility, the EGO LB5302 is among the top options. It's so quiet that says that noise levels are low enough that hearing protection is not needed -- something that can be said of few other blowers. Most experts and many users describe the EGO blower as easy to handle and control. DeBoer compliments the lack of vibration, which makes it easier to use the blower for extended periods of time.


Great warranty, with a caveat. This EGO blower is covered by a long, five-year warranty, but the company will only honor that if you buy from an authorized retailer -- currently Home Depot along with some local retailers. Overall, durability looks excellent. Reports of faulty blowers or batteries are not unheard of, but the majority of complaints we spotted were about the short run time on high speed -- and some of those cases might be the result of unrealistic expectations as the high-speed run times reported are in line with manufacturer claims and independent test results.

AUKEY Mini Drone Review

This is an unbelievably stable and easy to fly drone. Incredibly great and fun. I have had many drones and for a micro drone, this thing is more fun, especially indoors, than any other I’ve had. The flips are especially fun, almost hilarious. I highly recommend this drone. The other drone that I have seems like the gyros and are not as effective as this one. A good test is to bring it up and release the sticks. You see it drift very slowly, which is normal. To test the effectiveness of the gyros, you can fly it forward quickly and then just release the stick. The drone quickly stops moving forward and becomes stable almost immediately. What a great drone.

This thing is a blast to use. It is much easier to fly than I thought it would be. It balances rather well and will actually hover in place when you are not moving the joysticks. If it ever does not hover in place there is a calibration procedure that is easy and quick to do that will get it hovering in place again. This has full 6 axis control, forward, backward, left, right, up, and down.
This also will do flips in any direction with just the press of a button. There are red and blue lights on this AUKEY MINI DRONE. Always keep the red set of lights facing you, that is the rear of the drone. This will make it much easier to fly.

This drone includes a spare set of propeller blades, however I do not think that I will need them for quite a while as the set that came with it is not showing any signs of wear.
I have crashed this thing more times than I can count and it is still in 100% perfect condition.
You will need to supply 2 AAA batteries for the controller.

Overall this is an excellent mini drone and a perfect toy for kids. Please watch the video and leave a comment if you like it. Follow us on facebook and twitter.

Dangers of Smoking Cigarettes

Hazards of Smoking

In the past, I've told you concerning the effect toxins can have on your health. But nowhere can you locate a more focused source of environmental pollutants and chemical toxins than in single vaporizers e cigarette.

As vaporizers e liquid junkie, I understand this isn't what smokers want to hear. But, whether you currently illuminate, have stopped the habit, I've never smoked at all, this is information you want to understand.
Vaporizers E Cigarette

The sad truth is that every eight seconds, someone in the world dies from tobacco use. That translates to about 5 million deaths yearly. In reality, half of all long-term smokers may die a tobacco-related death. As Clint Eastwood once said, "Do you feel lucky? Well, do ya?"

Then there is secondhand smoke, which impacts anyone living with a smoker - or those working in or visiting a smoke-filled atmosphere. Secondhand smoke contains over 50 naturally-occurring chemical substances, 11 of which are known to function as Group 1 carcinogens. And what about that vaporizers shop smoldering in an ashtray? It turns out that the smoke from a smoldering vaporizers may contain higher concentrations of the toxins present in vaporizers for sale smoke than exhaled smoke does.

Make Me an Addict

In case you think cigarettes are simply tobacco leaves rolled in paper, you're about 597 ingredients off. Some components are added for taste, but research shows that the essential intention of using additives would be to enhance tobacco's potency. And that means more folks who try smoking become hooked. Along with the additives, they are employing are shocking.

I remember hearing something about "the list" of tobacco additives back from the 1990s when tobacco companies first began being taken to work. But viewing the list again today that I'm a former smoker can be quite a jolt. After burning, a cigarette spews over 4,000 chemicals, such as over 40 known carcinogenic chemicals and 400 other toxins. These include nicotine, tar, and carbon monoxide, in addition to formaldehyde, ammonia, cyanide, arsenic, and DDT. To think I used to place these toxins in by body, 1 pack at one time.

Chemical Soup

Once on a time, smokes were only tobacco and paper. But, allowing the full "flavor" of this pitch to come through resulted in a bitter flavor. The alternative was to incorporate filters and flavorings to enhance the flavor. However, the vaporizers e cigarette manufacturers did not stop there. They found that a compound similar to rocket fuel helps keep the tip of the vaporizers e cigarette burning an extremely hot temperature, which effectively vaporizers e cigarette smoking. Adding ammonia to vaporizers e cigarette enables this smoking vapor to be absorbed through the lungs quickly. This, in turn, means that your brain can get a higher dose of nicotine with each inhalation. Now that's efficiency.

Here's a listing of the most poisonous ingredients used to create smokes tastier, more stimulating, and even more addictive:

Ammonia: Household cleaner.
Arsenic: Used in rat radicals.
Benzene: Employed in making dyes, synthetic rubber.
Butane: Gas; utilized in lighter fluid.
Carbon monoxide: Poisonous gas.
Cadmium: Used in batteries.
Cyanide: Lethal poison.
DDT: A banned insecticide.
Ethyl Furoate: Reasons liver damage from animals.
Hint: Poisonous in large doses.
Formaldehyde: Employed to keep dead specimens.
Methoprene: Insecticide.
Maltitol: Sweetener for diabetics.
Napthalene: Ingredient in mothballs.
Methyl isocyanate: its own accidental release murdered 2,000 people in Bhopal in 1984.
Polonium: Cancer-causing radioactive element.

How New Technology Is Changing the Way We Earn (And Retain) Customers Online

Did you know that Twitter was launched less than 10 years ago? Or that Instagram is only five years old?

One of the most exciting things about the internet is the pace at which innovation happens. New products can quickly become an important part of the everyday lives of hundreds of millions of people in the blink of an eye.

The story is no different when it comes to marketing on the internet. While many of us are familiar with “tried-and-true” ways to acquire and retain customers online -- paid search, email marketing, etc. -- there’s a whole new wave of exciting technologies that are emerging right now.

What are they? And more importantly, how can you leverage them? To find out, let's take a look at some of today's most promising new technologies for earning new customers online, and how these new channels can influence retention.

3 New Technologies for Earning Customers Online

1) Native Advertising

Native ads are designed to “look and feel” like they belong with the content on the rest of the page.

According to research from Dedicated Media, native ads are viewed 53% more than banner ads. In other words, native ads give you a better chance of getting the visitor to look at your ad and visit your page. Not to mention, spending on native advertising is expected to grow to $21 billion in 2018, rising from just $4.7 billion in 2013.

Source: Business Insider

More specifically, sponsored content is a form of native advertising that aligns with the subject matter and design of the page in which it is displayed. It serves as an excellent way to engage site visitors by crafting material that they're genuinely interested in reading about. In fact, when done correctly, it can even be difficult to figure out which content is sponsored.

Here’s a version of the Buzzfeed homepage which was highlighted in August 2014 in TechCrunch:

Can you spot the ads?

Were it not for the small yellow tags which read “Promoted By," it would be nearly impossible to distinguish between ads and the rest of Buzzfeed’s content, right?

Here's another example from The New York Times of how leverages sponsored content:

See how the advertisement adheres to the card design used on the page to blend seamlessly into the rest of the content?

“Many publishers like Allrecipes are also offering native advertising products, which are increasingly seen as an effective way to reach consumers. Excluding ads on social networks, the research firm Forrester estimates that native display ads will increase to about 15 percent of the online display ad market by 2020 …The goal is to give consumers something that feels less like an ad and more like content they would choose to read or watch,” explains advertising and marketing reporter Sydney Ember.

Native ads are also becoming increasingly popular on mobile. For example, Deadspin -- a popular sports website (and a favorite of yours truly) -- intersperses sponsored content with the rest of its articles:

This ad fits both Deadspin’s formatting and writing style exceptionally well -- it has the same layout, some type of graphics, and same writing style.

Guest Post: Compare Used Hamilton Watches

The market of used Hamilton watches is very large and complex and also requires detailed study. No matter if you are new to this market or someone very experienced, you would be required to have knowledge in this field.

So the main Basis for Comparing Used Hamilton Watches with each other should be:

Brand Names: From new watches to the watches which were made in very old times, every watch has a brand name or the ancient watch house's name. In the fast increasing number of names, each has its own uniqueness which reflects its theme and history.

Period in which the watch was made: Many of the years have passed since these watches came into existence. So there had been many different types of designs, mechanical movements. As the watches of the 18th century would be different from the watches of 19th century, so each hold its own value and some are simply priceless.

The Factory Condition: The condition in which the watch is now is a very important factor to be considered. Also make sure of the all the important accessories are the default accessories or the genuine stuff. The most common things changed are the original screens are removed and replaced with a lower graded screen. Change in the original dials with different colored ones is also one field where genuine state of the watch has to be taken care of.

Limited Editions: the limited editions are always preferred over the other watches. The limited editions are limited in number and are often auctioned at high rates. So this is also the region of the comparison of used Hamilton watches with each other in their class.

Taste: the most important factor while comparing the used Hamilton watches is one's taste. One should buy the watches according to taste, not according to the uniqueness or any other factor. You should be totally satisfied after buying a used Hamilton watch else there is no fun of spending huge sums on it.
