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).

As an example, an average mobile phone battery is 3500-4000mAh, so a power bank with less than 5000mAh can give us up to 1 charge.

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.

The current intensity indicates the charging speed that the power bank can offer. Higher intensity allows for faster charging in devices that support it.

This value refers to the maximum current intensity that the power bank can offer to the connected device, but it remains compatible with all devices that charge with lower intensities.

The power bank does not offer fast charging.

Magnetic wireless charging that snaps onto the back of iPhones (12 and newer).

Qualcomm fast charging technology, widely used in Android devices (Xiaomi, Motorola, Realme, etc.), mainly through traditional USB-A ports.

Simple wireless charging without magnets (place the device on the power bank).

 Holds the device securely with magnets while charging wirelessly (MagSafe / Qi2).

You can take it with you on the plane. It must be carried only in your hand luggage, never in checked baggage. Up to 2 power banks per passenger are allowed. Always check the airline’s rules regarding in-flight use.

 It features a solar panel for slow recharging from the sun outdoors.
