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.
When looking at a power bank that has a charging capacity of between 4000 to 5200 mAh, you are typically able to charge a smartphone and tablet 1.5 to 2 times. Having this extra charging capacity is great for the times you need more than one boost before you can get to a wall charger. For business people on the go who use their devices throughout the day, this power bank size is the perfect gift. With customization options ranging from engraving to full-color printing, you’ll be sure to find the right charger to fit your brand. Your logo will get maximum exposure when it’s imprinted onto one of these popular, on-the-go promotional items.
