    Needed two USB for charging multiple devices, it did take about 7 hours to get to a full charge, but after that, it was nice and fast charging.

    The power last a longtime and it charges fast. It should be 4 1/2 stars only because it is kind of heavy. It still will fit in your pocket but will be sticking out.

    The capacity and dual ports are ideal for people with too many devices who routinely forget to check the charge of said devices before going on explorations in foreign cities. The only downside is the size is a little big for a small purse, but considering how many times it charged my phone and even my wireless earbuds once, I can deal with the size and weight.

    Anker is a great, reliable brand. This lasts and lasts but is easy enough to pack into a day bag. I like the carrying pouch that comes with to store cords.

    We got this before going on a week long trip and we didn’t have to charge it once. If we needed to charge a phone we just plugged it in and put it in the bag. Incredibly easy to use.

    This is a great charger. Being able to charge 2 items at a time is helpful and we have used it to charge phones several times on one full charge of the device.

    My son was going thru a spit up & he was staying at friends & when he would call me his new phone would always be low on power. He told me it was the best present I got him for his birthday as he could power up all his devices one day & have Power on all items for four days. Excellent produce & 2 years later still using it. He also said it not heavy so it could be in ones pocket or backpack. I’m so glad I researched this & found this at Best Buy. Today I purchased a refrigerator, big Purchace but I was happy with sales and service, I get it in a few weeks. Thanks Best Buy
