    The fast charge can charge my phone from 0-100% in less than 2 hours. Great for small electronics too like kindle, bluetooth headsets and handheld game systems.

    I’m so happy with this charger! I have charged 2 iPhones, an iPad and an iPod Touch with this charger and still 2 out of 4 indicator lights remain lit. Using the fast-charge port, my sister was able to fully charge her nearly empty iPhone during her 1-hour visit. Even though it’s a little too heavy to carry in a purse, I know I can rely on this charger during a multi-day power failure.

    It's a large battery pack, with 1 USB-C and 2 Regular USB. The USB-C can be used in both directions (charging the battery pack or charging your phone) which I thought was a nice feature. Please be aware that it is a heavy battery pack. It got me through a week of camping without being near power to charge my phone.

    Great not-so-little power bank!

    Great little power bank. I bought this to keep charged for use when the power goes out or during long car trips. It charges itself surprisingly quickly, and charges my iPhone and iPad without issue. I used it during a recent 28-hour outage, and didn't have to worry about how to charge my phone. Highly recommended!

    I didn't try it so much yet, it's been 2 charges of the same phone and still have power. It came with some charge, about 60%. The only drawback is the weight, it is too heavy. I use to had a 20,000mAh charger before and was not so heavy, so is not a good idea for taking a walk with it.

    I really like this charger unit. You can reload an iPad almost three times and phones about 4-5 times. It’s a bit bulky but it’s expected for the capacity. I wish it could be plugged into an outlet to charge but otherwise it’s a good unit.

    Its huge but it does charge all my tech devices such as smart phones, ear buds, headphones, and even my work laptop. It lasts a couple hours, and the only thing I can complain about its huge. I also got it on sale, better than amazon price. I use it for traveling.

    Really good quality. Charges my devices several times. It's bit heavy as it has high amp, I would not say good to take for backpacking as size and weight but good to other trip as you dont wanna charge your power bank multiple time.

    Excellent portable charger to used for your cell phone, mp3 players, ipod, etc. This charger keeps my devices charged up in no time. Fast charging. This device doesn't need charging very often. When it does, the charging doesn't take very long.

    This item works great and stays charged for lengthy amount of time. My only complaint is that is its size. If you are looking for a portable charger for your purse I would say this one is a little too large but other than that I am happy with my purchase.

    If the manufacturer could figure out how to decrease the size of the device as well as the time it takes for the device to recharge itself I'd be even more satisfied. That being said it's a big heavy battery that delivers

    This has been a great portable battery so far. When it's fully charged it will recharge my galaxy S10 from 40% to 100% in about 20 minutes. It is actually faster than the wall charger and it didn't seem to bother the battery's charge at all.

    Works as advertised. I'm a devoted Apple user but the iPhone SE is a disgrace. It's a power hog. Bought this brick to recharge as I travel cross-country and on long car trips. People here in California have called them, literally, life savers when the power cuts out. And because the power companies are more interested in the bottom line than customer satisfaction, they have saved lives. Some people have bought several. They take a few hours to charge each one fully but that's a heck of a lot cheaper than a generator.

    I've been testing this out with a portable solar panel for travel charging. This thing charges well and holds a lot of energy. So far I've fully charged my iphone 12 pro twice, and some bluetooth earbuds, and it's only at the 75% indicator. Definitely a steal. My work requires some traveling, so having this will give me peace of mind when using my devices for navigation or entertainment on the go. Side note: This thing isn't designed to charge laptops, but it DOES charge my macbook pro when it's off. (Only works if your laptop is off though)

    Great to recharge the phone battery when electricity is no available, eg power out. It is too heavy to carry in a pocket or purse, but is perfect for multiple charges in an emergency.
