    Haven’t gotten that much use of, but, its been fantastic of that that we have been able too. Just make sure it’s plugged in well when charging. Other than that, the price is stellar for the product you receive.

    I enjoyed using this product because it allows for me to use my smartphone the entire day without worrying about the battery. There’s enough power in this product so that neither does my friend!

    We recently used it on a flight to Hawaii. My husband and I used it for our Airpods Pro, iPad, and a MacBook Pro. It worked great! Just be certain you have enough USB ports for you devices. It only has 2 outputs. I also bought an adapter on Amazon so, when needed, I could charge all 4 devices at once.

    Great portable battery charger. Took it on a cruise and recharged our cell phones several days and still had 70 percent charge left.

    I love this charger. My girlfriend and I used it on a recent camping trip and it supplied multiple charges to our phone over the trip so that we could stay connected to the world when needed. It's heavy and sturdy, and withstood the elements (heat, banging around a bit in our bags, etc.). I would definitely recommend it to others.

    Love this! I bring it to work and use it to charge my phone, ipad and earbuds. That's a limited places to sit in the breakroom where i work and even less places near an outlet to charge things if they are low, which is why i night this. It charges great!

    Way bigger than expected, charges up to 3 devices at once (very quickly as well). I’ve charged my IPhone, portable speaker, and vape at the same time to a complete charge and the battery pack never went below a 70% charge.

    This portable battery phone charger works great! It will charge the phone many times. Just a precaution, if you discharge the battery to below 25%, be ready to let it charge for several hours.

    Got this as a gift with a heated wearable blanket. Although it is bigger than less mili amp batteries, it still fits into the pocket. Lasting longer than smaller batteries. Does take longer to charge.
