Weight: 450

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.

    I start the evaluation with only a first contact and I will come back later with a more complete opinion. The packaging cable is unacceptable, the USB adapter does not connect easily, as it does not hold the charging mAh. So, I use the cable from the charger and it charges my wife's mobile phone as much as the wall socket, about 2,600mAh. Mine, which is 22.5w, charges it around 3,500mAh, while the wall socket gives me 4,200mAh, so it is about 15% slower than the promised 22.5W. When both mobile phones are charging, we fall to a maximum of 2,700mAh in total, meaning we fall quite a bit in terms of time. I don't know if I should give it 3 or 4 stars. I'll give it 4 and see!
