The device took 5x longer to charge than it claimed and could not fully recharged simple devices like an iPhone 7, iPhone 6s,Samsung Galaxy 7, and could barely charged to full a Samsung Note 5.#3 in the test worked until it hit half capacity and then popped and no longer would take a charge while the other 4 showed accelerated degradation meaning bad quality parts or recycled battery cells
