Laptop power banks
What does mAh mean?The abbreviation mAh stands for milliamps per hour and is the unit that indicates how long (per hour) the power bank can deliver a certain amount of current (mA). A standard adapter with a smartphone has an output of 1000 mA. When you charge your smartphone for an hour, your smartphone contains 1000 mAh. With a power bank of 10,000 mAh you can then charge your smartphone 10 times. |  |
The difference between power banks.
Each power bank has its own capacity and that shows how often your electrical appliances can be charged with your power bank. A power bank with more capacity (mAh) can therefore charge your devices more often compared to a power bank with less capacity. Some electrical appliances consume more power and therefore require a higher capacity charger. For example, a 40,000 mAh power bank is suitable for charging your Macbook or Laptop where other power banks can not.
How often can I charge my phone with a power bank?
The number of times you can charge your smartphone, tablet or laptop with a power bank depends on the capacity of the battery. You can easily calculate how often your devices can be charged with a power bank when you devide the capacity of the power bank by the capacity of your electrical device. For example: Capacity smartphone is 4000 mAh and power bank 12000 mAh. Then you can divide 12000 mAh by 4000 mAh and the answer is three times.
