One of the worst things about working from a laptop, especially one that’s much older, is that you don’t have much juice to stay portable. In fact, at the rate you’re always plugging a laptop into an outlet and recharging the battery, the total life cycle ends up depleting fast. My laptop, for example, will only last for a little longer than an hour when unplugged from the power adapter. When I first bought it about a year ago, it lasted nearly three hours when fully charged.

If you want to get any amount of work done while you’re away from a wall outlet, and it does happen quite often, then reduced battery life becomes quite a serious problem.

You can always buy a new battery, but I’m of mind that it’s a waste of money since the new battery will just deplete fast eventually. That leaves only one option, an external power pack that will provide extra juice for your laptop, notebook or netbook.

According to Powertraveller, a portable power pack manufacturer, one of the most asked questions is:

“Can you make a battery with enough charge to run a laptop all day?”

After all, it’s a valid question. A full day of battery power would afford sufficient time to get work done while you’re traveling or just out in public somewhere.

Well, now Powertraveller is offering a massive power pack that will actually provide a full days charge. The Silverback Gorilla is a 60,000mAh lithium polymer based battery pack that will provide an extra boost of up to 14 hours at a time. Rightly so, it’s designated as a UPS or uninterruptible power supply and it’s meant for use while traveling, obviously.

It includes a 240-volt AC output socket which can be quickly swapped to DC power and dampened, in order to charge other devices like a smartphone or tablet. Two additional USB outputs allow for several devices to be charged all at once. This is especially useful if you’re always on the go and you rely on multiple gadgets out in the field.

An integrated LCD relays all the necessary information including output voltage amounts, remaining battery life and more.

Better yet, this thing is quite efficient. A distinctive auto-cutoff system will cease all power connections if nothing has been plugged in for two minutes. That way you don’t have to worry about the Silverback losing power when nothing is connected.

Of course, this thing is pretty solid with dimensions of 9.6 x 8 x 1.3 inches and a total weight of 5.5 pounds (2.5kg). It’s obviously not going to fit in your pocket, but it will probably drop nicely into a laptop or messenger bag. At 5 pounds, that’s about the same weight as a bulky laptop so the total carrying weight shouldn’t be an issue.

The Silverback Gorilla is slated to launch this summer, with a cost of $460 (£300). That’s not exactly a bargain, but you can’t deny how valuable a power pack of this caliber would be. Luckily, Powertraveller also makes smaller power adapters for those of us who are okay with just a little extra charge instead of a full day.
