I bought this item because it was on sale. The quality is good and works almost 100%. Got the unit for 2days now and the only part of the power bank does doesn't work correctly is the solar charging. The LED light is super bright and the wireless charging works well. The unit was left out to charge in direct sunlight for more than 4hrs and never even charge up a single notch. Very disappointing that the solar charging does not work. Unfortunately the product cannot be returned as it is a sale item.
