The capacity indicates how much energy the power bank can store. The greater the capacity of the power bank, the more times it can charge your phone. It is measured in milliampere-hours (mAh).

"The most popular capacity for a very lightweight power bank is around 5000mAh. For reference, an average mobile phone battery is 3500-4000mAh, so a 5000mAh power bank can give us approximately 1 full charge."

MagSafe

The MagSafe technology for power banks allows for wireless charging through a magnetic connection. Simply place the power bank on the back of your device: it connects magnetically and charges, remaining securely in place. For example, with a MagSafe power bank, you can charge the iPhone 12 or a newer model without a cable, just by placing it in the correct position. Compatible devices with MagSafe mainly include the iPhone 12, 13, 14 and newer, as well as other devices that support the same technology.

If your device is compatible with MagSafe, power banks with MagSafe offer high portability without the need for cables.

The weight of the power bank depends mainly on its capacity, but also on the material and functionality it offers (such as additional charging ports, wireless charging, flashlight, etc). For example, 10000mAh power banks start at around 200g, while 20000mAh ones start at around 300g.

Heavy-duty powerbank. Not recommended for frequent transportation, mainly useful for periods when we do not have access to electricity for several days, e.g. camping.
