Best iPhone Battery Backup

Just as cellphones and music players and game consoles are designed to cater to the current demand for mobility, so are computers. Some computers have been reduced to the size of a cigar box, and isn’t much heavier either. And guess what? It runs on batteries.

Back in the olden days, portable computers used nickel cadmium (Ni-Cad) batteries which weren’t environmentally friendly, and then nickel metal hydride (NiMH) batteries, which were much more efficient. However, NiMH batteries ate the dust when Lithium Ion batteries became the de rigueur power supply for most mobile technology including mobile phones and portable computers. Some battery manufacturers claim that their laptop batteries can run for more than 5 hours, but it’s probably more realistic to expect about two to three hours of normal use.

So what do you do when you’re on a transcontinental flight and you simply have to finish that report before you get to your destination? You have three choices: work really fast and finish before your laptop shuts down on you; have an extra battery (fully charged); or get an external battery extender.

Most laptop battery extenders in the market have about 13200mAh and can only be used for gadgets that take 5V. One product that packs a whopping 19500mAh of juice is the IMP19500 Universal Battery Pack by IMaxPower. While this product is primarily designed for laptop use, it can also accommodate other gadgets such as mobile phones and game consoles. These include all models of the iPhone, iPod Touch, iPod, Blackberry and Google’s G1 Phone.

To give you an idea of what to look for in a battery extender, consider this: At 19500mAh, the IMP19500 can fully recharge a laptop taking 11 volts just once. This means that most laptop battery packs can only partially charge your laptop. Now if your laptop requires less juice to recharge, then you can probably use it longer with 19500 mAh than with any other battery extender. In addition, laptop battery extenders are priced from $134.00 plus shipping while the IMP19500 is priced at $109.95 with free shipping in the US.

The IMP19500 is compatible with most brands of laptops, including Dell and HP with a voltage range of 12 V, 16V and 19V. When purchasing the IMP19500, specify your laptop model to get the adapter you will need. You may check out the IMP19500 at www.imaxpower.com.

The world has changed considerably since the advent of mobile devices. It is now accepted practice to be on the move at all times with no worries of missing that important call, email or message because we carry most of this capabilities in our pockets. Nor is it a hassle to bring your children along to long trips because they have their own diversions whether it be their cell phones, MP3 players or portable game consoles, often all in one package.

What does serve to ground most people is the need to be near an electrical source to charge their batteries. Because of the extended capabilities of most mobile devices, there is always the problem of running out of the necessary juice to sustain one through all those applications and amusements. This is where the IMaxPower IMP500 comes to the rescue.

There are quite a few battery extenders in the market today, but none really live up to the capability of the IMP500, simply because it provides 5000mAh of juice in one charge, much more than other battery extenders. And when it comes to battery extenders, isn’t the proof of the pudding in the amount of extension it actually provides?

Sure, there are some battery extenders that are sexier, being cableless and allowing the mobile device owner to slip their gadgets into it and continue using it comfortable as a phone or whatnot while recharging. However, the advantages of using the IMP500 with its retractable USB cable are significant.

The most important advantage, as pointed out earlier, is that none of these devices provides for multiple charges as much as the IMP500. The IMP500 provides up to 4.8 charge cycles for a 3G IPhone, for instance. That translates to as much as 38 hours of use per charge of the IMP500, the time varying depending on the actual applications used, but even for video there has been testimony of as many as 6 full-length feature videos of continuous play. What does this mean? This means you no longer need to worry about running out of battery even on a long flight of more than a day, even with continuous use of the mobile device.

Another advantage of using a USB cable is that it makes the IMP500 much more versatile. With the correct cable type, the IMP500 can provide charge for almost any kind of mobile device that accepts a USB connection for charging such as the IPhone, Blackberry, Kindle, Nintendo DS, and so on. It is really just a matter of having the right kind of cable i.e. micro versus mini USB, which makes the IMP500 a multipurpose item, certainly worth much more than its $59 price tag. Try fitting your Nintendo DS into that sexy cableless battery extender designed specifically for an IPhone! One user even reported using a 4 port USB hub to charge four gadgets at the same time and was amazed that the IMP500 was able to charge each one simultaneously. That’s convenience.

Moreover, you have a choice of charging the IMP500 itself with the rapid AC charger (available online at a minimal additional cost when ordered with the unit) or the accompanying USB charger that you can plug into your portable or desktop computer. With the rapid AC charger, the IMP500 is fully loaded and ready to go in as little as 1.5 hours.

And last but certainly not least, the price for an IMP500 is considerably less than for cableless battery extenders, which start from $80 up, even with the lower power capacity. Many of the other battery extenders are also more fragile than the IMP500 because of its tough yet elegant casing, and it is not much bigger than the IPhone, so you will be able to use it much longer with more gadgets and still be highly portable.

Despite these advantages, some users do have a beef with the fact that the IMP500 does no automatically shut off when a mobile device is fully charged. The worry is that this may cause the mobile device to overheat. The presence of the LED indicator is meant to indicate to the user that the mobile device has finished charging. There is actually little danger of overheating as the IMP500 has a built-in current protection unit that prevents the mobile device from accepting more than the capacity of its own battery.

However, the designers of the IMP500 welcome such feedback and are determined to improve an already great product by addressing minor concerns such as these at the earliest possible opportunity. There are plans to adjust the LED trigger threshold of the next generation of the IMP500 so that the unit will automatically turn off when the charging is done. This is also one other good thing about the IMP500; the manufacturers stress not only excellence in product design, functionality and safety, but also after sales service. All concerns are addressed immediately with a minimum of fuss or dispute.

IMaxPower has been in the battery extender business since 2003 and has continuously come up with better products that satisfy the needs and address the concerns of the mobile device user. The increasing demand for the latest model IMP500 is testimony to its capabilities, and the people behind IMaxPower are determined the product will continue to go beyond expectations of its customers by unflagging research and development of an already amazing product.
