    This charger is WORTH THE MONEY! I've charged my Kindle, 2 iPhones, and my wife's iPad several times on one charge! It takes a while to recharge, but that's the only price to pay for an awesome battery. Get one...it's worth it!

    There are many out there that cost more, and this charger is just as good. My son requested it for his birthday. He uses it for camping and day trips to keep his phone charged. It holds multiple charges. He has no complaints.

    It is small but charges my Oculus Quest, allows me to use it while charging, and is small enough to attach to the headset, and store in my Quest carrying case. It has USB C and Regular USB charging ports.

    Always been a fan of Anker products. Very reliable and great value. I recently got this for my parents for a trip they went on. They love it. This pack does take a while to fully charge from empty but it lasts a very long time.

    The best portable charger ever. I left this battery in my bag for 4 months & it was still fully charged. I was amazed. One of my best investments hands down. Buy it! I highly recommend it

    This worked out so well for me and my family especially when we had full day plans or events to go to, so none of us would have to worry about our phone dying while we were out. It also charges really fast which impresses me!

    Got this for my wife and it's amazing how quickly it recharges her phone from under 30% to 90% in about 40 minutes while she's using it for Pokemon Go. Also great for her portable camera battery charger.

    I use this to charge my phone, headphones, tablets, etc. I can fully recharge all of my devices multiple times before this thing is out of juice. The only thing that could be better is if it had USB-C...

    Holds enough charge for 3 iPad uses (I hope that makes sense) but I really like it. Note though, if you have a USB plugged in that’s not in use, it takes won’t charge as fast as if it’s plugged into a microUSB bare.

    While on the TV studio filming a live show...many found their smartphones low on battery power. I charged 3 phones and mine and could still run my tablet/MacBook. The battery pack was still above a 3/4 charge.

    My old battery pack only charged my note 8 too maybe 24% . But this one charges it fully 2 to 3 times if need be. It does take a long time to fully charge though but it works great and last a long time.

    I have a Pixel 2 Xl which has a fairly large 3,500 mAh battery and I can charge it several times with this battery pack. I usually charge my phone and one of my headphones with it and I rarely charge it back up.

    I travel a lot on the road. With a hybrid, I do not use charging outlets in car due to possible draining of car battery so a power bank is necessary. This one has an incredibly long battery life so I am happy!
