Green Cell power banks

1. Battery capacity in the phone The most important thing we need to check is the battery capacity in our phones, and this can vary from just over 1000 mAh to as much as 4000 mAh. Please note that there is an inevitable loss of energy during the charging process, which can reduce the actual performance of the Power Bank by up to 75%. This is a completely natural phenomenon and must be taken into account.
2. Power Bank for smartphones - What parameters to consider? If you have a phone that can charge quickly, it's worth choosing a power supply that supports 2.1A or QC 3.0 charging, so you can charge up to twice as fast as other models. Please note, however, that the quick charge option is useless if the phone is not compatible with it.

Ultra Charge is based on three charging profiles - 5/9/9/12V. Depending on which device you connect, you can be sure that the correct charging voltage is selected and that the intensity is as high as possible. The technology guarantees safe and fast charging regardless of the connected device. With Ultra Charge we can charge most smartphones in 1-1.5 hours from 0 to 100%.

Each power supply comes with a USB micro-USB or USB C cable (see specifications) that can be used to charge the power supply, and if the phone has a suitable wall outlet, it can also be charged via this cable.

In fact, any Power Bank will be suitable for our phone as long as it is a smartphone. Everything depends on our preferences and purpose. If you need a handy device that doesn't take up much space and can be carried in your pocket, we recommend Power Banks up to 10,000 mAh. However, if we want a particular power bank to provide power to other devices, we suggest a model twice the size of 20,000 mAh.
