While power banks come in many different styles, colors and sizes, one of the primary differentiators is their capacity. Measured in mAh (milliampere-hour), their capacity determines the amount of charge they can hold and consequently, the power they can supply your devices. While it’s hard to determine an exact number of charges, the general rule of thumb is that the higher the mAh rating, the more capacity the power bank holds.

Power banks with a mAh between 2500 and 3900 can provide either close to or a complete charge, depending on how much battery life the device has left. An average smartphone requires around 3000 mAh for full battery life. Purchasing a 2500-3900 range power bank will provide your clients a boost to their tablets. People will begin to remember your brand favorably when they see your logo on such a handy item. With many customization options, ranging from full-color printing to engraving, you’ll be sure to find the perfect portable charger for your promotional needs.
