    I’ve owned many portable chargers and this one is by far the best! You can charge 2 things at once & it charges pretty quickly

    I purchased this charger for our Disney World trip this summer. It was nice to use my iphone throughout the day without the fear of my phone dying. The recharge time was a little too slow in my opinion otherwise I would have given this product five stars.

    Can’t beat the price and the size of the battery. Main reason for purchase was to have a backup when power goes out and travel.

    Got it on sale. Good for sale price. Charged my S9plus 2x and a iPhone 6plus 1x. Think they should give the size of phones as a reference when they say how much devices it can charge. Like the size.
