    I wanted/needed an external power source with more USB-C and fewer USB-A. Also, I wanted 20,000mAh (not 10,000mAh). This charger provides 2 USB-C and 1 USB-A. So far, so good.

    This little pack for the cost is awesome. I use it when im put and about, though its going to come in good when my son and i are playing pokemon go over the holidays. It does a fast charge with one device connected, and regular charge with two.

      Glad to hear this power bank is keeping up with your adventures! It’s great that you’re getting fast charging with one device — that’s exactly how the smart output management is designed to work. Hope it powers plenty of Pokémon catches this holiday season!

    We purchased these power banks to use in heated stadium seats. They worked very well and hold a charge for a good while. I'm not sure of the exact timing. Very pleased!

    Although heavier than I expected, this battery charger has replenished my phone multiple times (about 25% per charge) before needing recharging itself.

    This is a substantial battery backup at an attractive price. I also like that even though it is an imported product, it is a familiar brand that has always been reliable.

    The best portable charger because it can charge my phone 3 times without needing charging itself. It's a bit heavy but I'm okay with the weight because of its power. I bought it on sale so the price was reasonable.

    Perfect for my power needs on the road. Has long battery life and the remaining power display prevents being surprised when it runs out. Charging time is very reasonable for the size of the battery. I am thoroughly satisfied with this product.
