With a street price of $144, at first glance the Energizer XP18000A seems expensive for a battery. But consider that this 1-pound, 18,000 mAh device has enough power to more than double your notebook’s endurance or quadruple how long your phone lasts on a charge.
With this much juice, you can save money on extra notebook or smartphone batteries. If you were thinking of replacing your older notebook because it doesn’t get as much battery life as you need today, you can delay that purchase for a while, saving yourself hundreds of dollars this year. Being able to get work done in areas that don’t have AC power (example: an airplane) also saves you time — and time is money.
