Review on Portable battery Romoss Sense 8P , 30000 mAh, white by Ada Kowalczyk ᠌

It is strange that there is little description of the function of indicating the input / output current and voltage. By actually pressing the button, when charging the phone, you can see the voltage and by pressing again - the current (by the way, it helps to understand when the cable is bad) photo 1-2. when charging the device itself, he sees what voltage and current it is being charged (photo 3). At home, you will understand what the charger gives out and what quality the cable is. On a hike, I, using the charge ammeter, positioned the solar panel.
