To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Super slow. It took 2 hours for this to charge my phone from 41% to 48%. It is long which is nice, but not worth it. The charge is too slow. I wasn't even using mybphone. It sat and charged. I was expecting a full battery but no. Buyer beware.
