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 powerbank capacity for long autonomy." 2. "
" 3. "On average, a mobile phone battery has a capacity of 3500-4000mAh, so a 20000mAh powerbank can give us approximately 4 charges."

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.

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 can provide sufficient intensity for fast charging. To charge a device with fast charging, it must also support it, otherwise it will charge normally with regular charging.
