While power banks come in many different styles, colors and sizes, one of the primary differentiator amongst powerbanks is their capacity. Their capacity, which is measured in mAh (milliampere-hour), 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 1000-2000 mAh, you are looking for a small quick fast charge to your smaller type device. This capacity will only give you a small bump in battery power for small devices like a mobile phone or small portable speaker. This size of power bank or charger is great for a lower price point giveaway for a small quick boost in battery!
