Buyer Guide


If you are looking for a power bank, one of the most important things is the capacity of the bank. This is often indicated in mAh and the number represents the capacity of the energy the battery can hold when fully charged. So for example, if you have 3000mAh phone and you want to fully charge it, you should get a power bank with a capacity of more than 4000mAh. Since there is not a direct 100% rate, you should aim for more than the device itself.

Most power banks come with capacities of over 5000mAh. And most modern cell phones have batteries of around 3000-3500 mAh. Also, you should consider how many times you want your device to be completely charged. For example, you can use up your cell phone battery for 1 day and you have 3 days hiking trip, so you would need 3 full charges? Then if the phone has a 3000mAh battery, you would need at least 10000mah power bank.

Power Bank or Charger
