How to Buy Your First Portable Battery

There's someone says " happiness is a fully charged battery". If you travel a lot, you know how quickly you phone,tablets, iPads, and other device run out of juice. So, people trend to buy some portable charger to keep their cellphone charged whenever they go. Choosing the best battery charger from many choice selections is actually not an easy thing to do because of the possibility of being tricked by various low-quality battery chargers that proliferate in the market these days,especially true if this is your first time to buy portable battery charger.

All those question get into your minds. What kind of portable battery charger should I buy? They come in all shapes in sizes, with price tags to match. maybe you already have one in your mind which is lightweight and inexpensive, but you won't buy it if it won't charge your most essential devices. So how can you pick the ideal juice-box for your carry-on?

The very first things that you need to know in order to get the best quality of power bank is to look for the right specifications. That means you should know the size of the battery that your device has. Because the power bank you buy should have the same size as the battery of your device,at the minimum, so you can ensure at least one time's full charge for your electronic device.

Further, there are other features that you might be looking for an option to consider it as the best quality power bank. There are people who are quite particular about the display indicator. Some would prefer it to be a digital one so that they can easily see both the charging and discharging status of the portable charger. Aside from that, there are other people too who prefer to have multiple hubs or stations. This is for them to recharge couple of devices at once. This would be helpful if you own other devices aside from an iPhone.


Last but not least, one thing that I wanna stress out is: Although the chargers can easily be bought from any local store, buying online is yet another source from where you can buy quality products. Along with the good quality accessories can also save a great deal of time and money when making an online purchase. Besides, the product will also be delivered to your doorstep as quickly as possible. If you wanna buy that online, Poweradd is the reputable brand that you can trust.

You may say that you can type on the screen and finish the blog, yes, that's sure,but to me, I don't like typing long articles in that way. 

Let us start with types of computer keyboard. Everyone uses keyboard every day, but some of you may do't know how many types are there for computers. By knowing types of computer keyboard, you will find it's not hard to find the satisfactory one anymore.

Laptop Keyboards
The laptop computer keyboard is also called standard keyboard. Standard keyboards include Escape (Esc), Print Screen, Scroll-Lock, Pause-Break, Arrow and other functional keys. Functional keys allow you to tab, type in all caps, insert, delete and perform countless other functions. There's a new standard keyboards, it come with internet short cut keys, which allow you to check emails with a click of a button,store your fav websites and power on and off the internet. What's more, it is also ready for use with a USB port.

Ergonomic Keyboards
Ergonomic keyboards are specially designed computer keyboards with an aim to reduce stress on your wrists and forearms while typing. They have been around for quite some time now, and its been proven that the special contour designs of these keyboards are definitely worth the trouble. Ergonomics isn't a one-size-fits-all science, and there are some keyboards out there that claim to be ergonomic but are not such thing. If you can, test out a friend's ergonomic keyboard before you buy it. While there will probably be an initial learning curve, you should be able to tell pretty quickly if its something that's comfortable for you.


Gaming keyboards
As the name suggests, gaming keyboards are designed specifically for gamer. They include features meant to enhance gaming experience, as well as provide convenient usage for gamer. Those features like volume control, key lighting, programmable keys, interchangeable keys, touch screen to customize the keyboard, in-built joysticks,fancy lighting and so on. Gaming keyboards comes in all shapes and sizes,ranging from round keyboard to v-shaped ones, but this is mainly done as a marketing gimmick to attract gamer. There's some keyboards are just designed for specific types of games. 


Wireless Keyboards
Just as what the name shows, the keyboard don't need to be connected to the computer via a wire. The biggest advantage is that you are free from all the cables and it's really convenient. Wireless keyboards use three basic types of connections, Bluetooth, Infrared, and Radio Frequency to connect to the computer. All the three types of wireless keyboards need external power to function. The power comes from either 2 or 3 'AA' or 'AAA' batteries. A little of wireless keyboard may have an included battery,which can be charged with the help of a USB cable. Any they have one more thing in common, that is all of those types need a transceiver,which connects to a port on the computer and maintains contact between the computer and the keyboard. With so many types available in the market, choosing the right one can be difficult. Knowing the three kinds of keyboard can help you work comfortably and efficiently while keeping your office as cable-free as possible. Among the three kinds, the best one and most popular one is bluetooth keyboards. The technology is only effective over a short range, but it allows for reasonably high data transfer speeds and does not need a direct line-of-sight for connection.
Depending on your needs, one type of keyboard may be more valuable than another. The choices are plenty. as far as I am concerted, I don't think a cheap keyboard is suitable for you, since you use it every day,a relatively cheaper with excellent quality will save you money in the long run.

Replacement Battery for Your Cell Phone

Cellphone is a convenient means of communication. Nowadays, people always wish to stay connected with their friends and relatives, we are trend to use their handheld equipment several times in a day. This will surely have an impact on the battery life of our devices. In order to keep the phones working, a cell phone requires a battery that needs to be recharged periodically to keep the phone adequately powered. Mobile phone today have a lot of functions, certain media-intensive activities such as watching a television episode or streaming music will drain the battery faster than a simple phone call of the same duration can. But, users sometimes don't worry about this kind of things, for they can purchase quality alternatives from the firms offering cell phone battery replacement from good quality manufacturers.

Then do you know when your battery chargers need to be changed? There are some mistakes about this question. Some may say when the battery can't last as long as before and change is required. Some may think this is a waste of money, they will change until the battery really can't work anymore. When this internal device stops power supply, the device become inactive. By way of recharging, the power supply can be resumed thereby bringing back the equipment to the live mode. When this interna part exceeds its life span, it becomes ineffective and fails to hold the charge throughout the expected duration. In such situations, the old battery must be replaced with new one.

A battery's charged life does go down as you continue to use it but if it has halved or gone down considerably then it is a sign that you should change your mobiles battery. And you have to charge your phones more times then before.

Second, does your phone feel hot to the touch? This may be the case when your battery needs to be replaced. Most phones will warm up when you use them a lot, much like laptops do. If yours gets excessively hot though, it’s time to consider getting a replacement battery. This will be most apparent when you are playing a game or browsing the Internet on the device. The battery is working much harder than it should have to just to make sure your phone stays running. And too hot is not safe for you to use it anymore, it may be dangerous.

Third, use the phone as normal and pay attention to the battery level. If the phone dies within a few hours, or the battery level drops rapidly, this is a sign that the battery should be replaced. Yeah, I think you will notice this for charge a lot is really unpleasant thing. And when you go for holiday, you have to bring a cellphone battery with high capacity. Even at the mention of this will make me go crazy. I have experienced this.

Here comes the another question: where to buy cell phone batteries. You can find your replacement alternatives for mobiles from the retail shops,supermarket,or online stores. The customer can choose where you get your cellphone battery prepared. But one thing I should stress out is that you should make sure you buy it from a reputable store.

Why Cellphone Battery Dies So Fast

iOS 8 is here for iPhones, iPads, and iPod touches, and iPhone 6 and iPhone 6 Plus are available now for everyone, and while they provide more features and functionality than ever before, some people already worried about its battery. Updating to new software and upgrading to new phones can often have an impact on battery life. Samsung Galaxy S5 is currently one of the best smartphone in the market which stand tall above most of the other competitor brand. There's still so many people complaint about Samsung's cellphone battery life saying they dies really so fast. Battery life is the bane of smartphone owners everywhere. It's lovely being able to browse the net, play games, watch videos and update your status from everywhere and anywhere. But doing so too much can turn your phone into an expensive paperweight- at least until you get home and get it plugged in.


Tired of carrying your Android phone charger or backup battery to ensure a full day's worth of use? Then you should figure out what make your phone battery a rubbish? In fact, this is not difficult for we can always find out some tools telling us what's killing your battery. Once you've identified it,chances are you can longer your battery life by simply changing some settings and taking a couple of steps.

1. Overcharge our cellphones. I think most people may have experience like i do, when i go to bead, I usually put my cellphone for charging over night. We neglect the way we charger our phones.
Actually, this is not good for our phone's battery,as overnight charging may hamper the its life very badly dye o which you may even end up spoiling battery sooner than expected. Normally, It takes 3 hours for phone to fully charge, so never charge your phone more than this time.


2. Charger your cellphone more than it need to be charged. You may think everybody knows this, we charger only when we need it. But, we just sometimes charge phones so regularly, for example, when you see the battery goes below 50-40%, you can't wait to charge it. I have a friend who feels so uneasy when she see the battery is below 40%,in her words"I just have no sense of secure,so i have to charge it ASAP". Unless and until you are going away from the charging point, it’s not a wise decision to charge it way ahead than the battery zeroing point. Of course, it is also not wise to charge your phone when the battery goes to zero,it's too late.

3. Turn on your phone when it's charging. I should say you may turn off the phone, but most of people can't do this. Hmmm... some people can't live without even a few seconds, they just so addicted to phones. Think about your own behavior. It’s both being used and charged at the same time,watching movies when charging would happen to most of us. http://amzn.to/1oM82Xs
So, by changing the above behavior you will be easily saving the battery power which eventually increases the battery life. The battery is being stressed and is also unsafe. So, we may change the view that all things about battery is small things.We should pay attention to some ways when we charging,which is good for you and cellphone.so, why not?

How to Improve Your Cell Phone Battery Life

Most of us have replaced our old dinosaur land-line phones with newer, more modern and versatile smart cellphones. Some cellphones including some big names, just as HTC,Huawei,Samsumg, all most all of them have some cellphone types that claimed powerful, but unfortunately, it sometimes isn't the same as advertised. In fact, many Android phone users would be happy to make it through a single day, hoping that a nightly recharge is sufficient.

Why did this happened? There are many factors, we just name a few here. Firstly, a number of factors trend to make their devices more thinner and lighter, since nowadays, people prefer something that is slim but powerful, why not? I like this kind myself. Anyway, who wanna bring a thick brick in his pocket? It not only not beautiful in appearance, but also not convenient. But, this also caused some trouble for our customers. Thinner designs with less room for batteries, larger and brighter screens, faster quad-core processors, more software that runs in the background, and power-hungry GPS radios all share responsibility. Another very important factor is that, your smartphone is a minor miracle, a pocket-sized computer that can fulfill almost every whim. modern people just can't live without cellphones. Not only do it wow us with their ability to connect us to anyone, anywhere, at any time, they also allow us access to the vast knowledge base of the world, the ability to stay connected via email and instant messages and keep us entertained.

All the above reasons caused the endless complaints for all mobile user. There's the reasons why the battery seems never to last as long as promised. You must still remember clearly the disappointment when you needed to access your phone and found it all but useless thanks to a flagging charge on your battery? When there's a problem, there always some solutions. You can maximize the life of your battery by taking a few simple steps to prevent premature discharge. Here are a few of my favorites. And our Amazon store: http://amzn.to/1oM82Xs

Determine What is Using Your Battery the Most. To start off, let's see what's using your battery the most,there's always some APPs where displayed what has been using your battery the most since last you charged it. One thing to watch out for is if there are some APPs that you don't use often, but give a big burden to ur battery. If the answer is yes, consider uninstalling it or figuring out how to use it less.

Use the Battery Saver or Power Saver mode if your phone’s operating system has one. These features help you to control the functions that sap your battery’s power, including background apps, widgets, animations and screen brightness.

Never go to zero. I don't know if you found the phenomenon that when ur phone goes to zero, it takes some time to recharge it before the screen flash again. It is said that if you're going to be shelving any lithium-ion battery for a long time, try to leave it with at least 40 percent battery power to tide it over. Lithium-ion batteries don't hemorrhage power when their not in use, but they'll lose maybe five to ten percent of their charge each month. And when lithium-ion batteries get too low—like, literally zero percent—they get seriously unstable, and dangerous to charge. To prevent explosion-type disasters when you go to charge one that's been sitting around for a month or two, lithium-ion batteries have built-in self-destruct circuits that will disable the battery for good, if it reaches rock bottom. Now, you know how important it is, so, for your safety and the battery's lifespan, please never go to zero.
Update your apps. Applications often get updated to use less battery power, so you should make sure your apps are up to date. Even if you configured the phone for automatic updates, some apps still require that you manually install updates.

Heat is the enemy of all batteries, whether your phone's battery or your laptop's. You might be able to eke out a bit more life out of your phone if you take it out of a hot case or your pocket, don't leave it overheating in a hot car, and can manage to find other ways to keep it cool.

Choose a reputable battery bank pack for your cellphone. With removable batteries becoming more and more rare, you've got to take good care of the one you got. A lot of people will equip their phone with portable battery,a reliable provider is prominent. Poweradd maybe your best choice, with so many customers' reviews, you can believe your choice!
