Power banks are a must have if you’re on the go all day, a frequent traveler or simply someone who goes through a full charge more than daily. Having a one can be a game changer, and lifesaver, when you need a charge. They allow you to charge any device such as cellphones, tablets, cameras, gaming devices, laptops, Smart Watches and even laptops if it’s big enough. This “Charge no matter where you are” convenience makes a good one is worth every penny. Cheap ones tend to lose their power over time ours are of higher quality and should last you for years. In stand-by mode they can hold a charge for 6 months. Lower quality products tend to lose their charge in 4 to 6 weeks.
