Amazing charger with smart display. I’m using this as a backup charger for my laptop/phone, etc. It works perfectly charging my Lenovo Yoga 9i laptop and fast charging my Galaxy S25 Ultra phone. The connections are nice with USB A and USB C ports. They all work intuitively. The digital display is great. It shows the percentage of power left, power delivery, and estimated time left. It also shows the estimated time to charge while charging the bank,” said one reviewer.
