Buyer's Guide

The Tech Savvy Mobile User

It might be painful to admit it, but most of us are all but lost without our smartphone and various smart devices. With everything from airline ticketing to driving directions and up-to-the-minute stock market information just a click away, the modern person is firmly tethered to his or her devices.

And while reliance on a smartphone might involve the sacrifice of a bit of independence -- there's no reason to explore a city when you can be directed right to a destination, for example -- the convenience afforded by these multitasking devices is truly remarkable.

It's little surprise that so many members of the younger generations have chosen to give up on traditional landline phones and use their cellular phone as their primary means of communication. As the capabilities of and applications for smart devices continue to grow each and every day, it's hard to say how much further they will infiltrate into our lives in another decade hence.

What can be said with certainty now is that as convenient as a smart device has become, the other side of that equation is the extreme inconvenience we experience when our smartphone or tablet is not working properly. Woe to the traveler who neglected to print his or her ticket, much less even their itinerary or confirmation information, who has a dead smartphone and a flight to catch. And anyone who has ever been caught far afield in unfamiliar territory only to have their phone shut off, leaving them without maps or GPS capabilities, can describe their abandonment.

Whether you find yourself traveling for work or pleasure, or simply navigating your way through your own city to a new destination, chances are good that you be use your phone as an aid in the process. And whether you're placing calls to help you close a deal or just to catch up with friends or family, it's a safe bet you're doing so via cell phone. This is likewise true for checking news updates, sports stats, and email while you're away from home. In short, unless you're sitting at a computer, you're probably going to be counting on your mobile device for multiple tasks. Don't let your access to all the info and communication to which you're accustomed be compromised by a dead battery.

An External Battery Pack For Mobile Convenience

When considering the purchase of an external battery pack, instead of first looking at the various units available on the market, first take a look at the smartphone, tablet, and/or laptop computer that you actually use on a regular basis. While the circuitry inside a good external battery pack is complex and impressive, the choice of which unit is right for you need not be rocket science, but rather basic math.

Ask yourself how many devices at most you would need to charge in a given day, and consider their voltage requirements for proper charging. You can then conduct a process of elimination exercise, ruling out external battery packs that offer a surplus of power beyond your needs, thereby passing on units that cost more than you need to spend.

There are perfectly adequate external battery packs that cost a reasonable amount of money and are capable of quickly providing a full charge to any smartphone. If your issue is a battery often drained by the mid-afternoon, then one of these units should be more than suitable for your needs.

If, on the other hand, you frequently use your devices during travel and are often not in the proximity of convenient outlets, a pricier unit with the ability to recharge your device multiple times may be warranted. Just keep in mind that with this added power, so to speak, often comes more size and weight, which can be an issue during travel.

Using An External Battery Back For Emergency Preparedness

If power lines are down and you don't have access to a landline phone, your cell phone might be your only means of communication after a severe storm, a natural disaster, or even during periods of civil unrest or terror activity. And that can mean you are just one drained battery away from being totally cut off from communications with emergency responders, friends, and relatives, and from getting any news from the outside world.

In these situations, an external battery pack extends your lifeline of communications to those who might be able to help you, or to someone you might be able to help. It's a wise idea to make a modest investment in a decent external battery pack that you might hardly ever use; you'll be glad you kept it on hand and charged that one time you need to breathe life back into your phone and make a call for help, or to follow the news and see what's going on and when things are again safe.

First responders are well advised to keep an external battery pack on hand in their vehicles if not on their person. The communication afforded by a phone or a radio is critical in emergency situations, and many smartphone apps offer diagnostic and informational attributes that can be helpful in the field. The more reliable access an emergency responder has to information, the more effective he or she can be in helping to mitigate whatever situation has arisen.
