SOARAISE Solar Charger Power Bank - 25000mAh Portable Charger with 4 Solar Panels Fast Charging External Battery Pack for Cell Phone and Tablet

Charged to full before first use. Here is what I managed to do with it.2x Charged P20 pro from 0 to 100%1x Charged Samsung note 4 from 0 to 100%P20 pro again from 0 to 56% and power bank gone flat. It's certainly not 25k mAh as I can do the same thing with my other 20k mAh bank. Charged P20 pro in two hours on switched off phone. Will try it again but most probably I'll return it as its false advertisement by stating it's 25000mAh. More like 20k.

I have charged this unit once since having it and it just keeps going, very much recommended for that... I haven't had the opportunity to test the unit out camping but I'm looking forward to seeing how long it will last and how good it is in better weather.

Charges fast both in and out good product.on button hard to press.
