How to Choose the Right Power Bank for Your Device

Custom power banks are one of the most popular and useful promotional items on the market, but when it comes to deciding which power bank works best for your device, the options can be overwhelming. What’s mAh and why does it matter anyway? One amp or two? Big or small? While there might seem like a lot to consider, with the proper knowledge, choosing a power bank doesn’t have to be difficult.

Whether you’re looking for a power bank to keep on an office desk or to use at home, or for something more portable that’s easy to use on the go, it’s important to first decide how much power you want your charger to offer.  A mAh (milliampere hour) is a unit of electrical charge that is commonly used to measure battery capacity, and is often described as the battery’s fuel tank as it measures the amount of energy that the battery can supply on a full charge. For example, an Apple iPhone 6 requires about 2,100 mAh for a full charge (0% battery life to 100%). A 5,000 mAh power bank could therefore fully charge an iPhone 6 twice before the power bank itself needs recharging.  The mAh is important as it’s the easiest way to distinguish the strength or capacity of a battery, and in general, the higher the mAh, the longer the battery will last. When it comes to choosing your mAh level, choose a power bank with a capacity greater than, or equal to, your device’s mAh. If you do not see your phone listed on the chart below, please refer to your phone’s manufacture settings.

Another important area to consider is the amp output level. In short, the bigger the amp, the faster your device will charge. In most cases, power banks are designed to provide two amps of output current, however, some models only offer one. While two amps work most efficiently with tablets, most smartphones will charge just fine with one or less amps. Just be sure to choose a power bank with amps greater than, or equal to, your device’s requirements.
