    Used this while in Vegas, because of course I took a ton of pictures and videos that killed my battery fast, this was fast to charge and lasted a very long time, I didn’t recharge it my entire trip ( I also didn’t use it 24/7) I was there for 5 days

    Had this for a few days now and it's a great charger. Came about half charged, so charged it fully up. So far charged my phone three times and it only went down to three indicator lights. A little heavy, but is solidly made. Highly recommended.

    I am quite pleased with my purchase. It works well and charges quickly. I had to search thru the phone accessories section. I finally found the charger on lower level of back of the display grid.That part of the store needs to be reworked. Overall, I am happy with my purchase.

    Purchased for a trip to Hawaii. Glad I did as the plane had no WiFi. I was able to watch downloaded movies on my ipad during the trip. Also used the charger when lounging by the pool as there are no outlets in the pool area of course. Great device.

    Really nice portable charger. Took it camping on and off for two months and it performed great. When charging an iPhone XR, easily got over 2 charges, plus handling a couple rechargeable LED lamps before having to recharge the battery pack.

    Perfect stocking stuffer for someone who is on the phone a lot. I got one for my birthday and bought the same charger for Christmas for the other person. They loved it and still use it over a year later. This power bank holds up very well.

    Very handy and useful. Especially when you are out and about, camping trip, hiking, off roading etc. Works just as advertised! Very well made! Get one or two because i can bet you will have friends and family asking to use yours.

    Small, portable, and does the job. We used it at the amusement park to charge our phones all day and into the evening. My only regret is not buying the larger capacity charger

    Great battery pack for the price. It doesn't fast charge, though I knew that before purchasing. It does exactly what I need and recharges fast for future uses.

    Product performs in accordance to what it states it would do. The price for this product is worth it, and actually, not pricey. I recommend to purchase. The tool has been very helpful as I go about my day and need to charge my smart devices. (Apple)

    Bought 2 of these for my twins for gifts and so far so good. They really like being able to plug their phones into them during long car rides. Also great to charge their headphones while charging their phones.

    Got this for my sister for when she goes camping with my nephew and needs to charge her phone. She loves it and said she should have gotten one sooner. She said she is able to charge her phone a lot of times before having to charge the device.

    I guess I am unsure if the usb-c port is used for charging of my device or charging of the portable charger but that was part of the reason why I bought the product thinking it would other than that good product.

    I really love how compact this little unit is. It's small and light enough that I don't even know I have it with me. I do recommend getting one of the more powerful units, it's worth the extra cost.

    This is super slim, so it's great for slipping into a bag. Not a crazy high capacity, so it's best for small or low-power devices, but it's a good budget battery pack.

    This seemed to be the best value for the capacity. It seems to be working well. I have not tested the duration by putting a DMM to the rate of discharge and time. But it seems to last for 3 days with my Xmas lights.
