Customers are saying

Customers love the 20800 mAh Portable Charger's amazing battery life and attractive price. Its multiple USB ports and ease of use are also frequently praised, making it great for travel. However, some find it a bit large and heavy. The charger's capacity and overall performance are generally well-received.

    I have chargers my iPad and phone 2-3 times each with one charge on this. Works great. Takes awhile to charge fully if it is low, but worth the wait.

    This was a steal for me having a student coupon and a $5 certificate this baby came out to $16 bucks ! All aside it being a great deal it truly does come in handy for a college student or when your on the go. It charges my phone in 30minutes or less all depending on the battery life you have . I would recomd this because its a big help when i forget to charge my tablet.

    Got this huge MAH battery charger for long trips. Was not disappointed. Only tissue is it takes a while for it to recharge the portable battery itself so make sure you have a good Cable and wall charger.

    If you can get this one for 35 dollars like I did it's amazing lots of power and it's fast but I would pay up to 50 for this one . The only down side is the charging cable it comes with is garbage it breaks fast but you have so many USB cables around the house it's no biggie. Charge it over night as it takes long because it's 24000milliamps

    This portable battery pack is great. I used it multiple days in a row and did not need to charge it. It is a bit larger than most people might want to carry around but it does not weigh as much as i had anticipated. I would definitely pick this up if going on a long trip or if you have multiple devices to charge simultaneously.

    Me and two other guys "survived" with this charger. I only charged it twice in one month but it kept 3 cell phones charged for 32 days. Not only that, but it will charge your phone faster than a wall plug on airplane mode. I have no words...it is awesome!

    I couldn't believe how much power this portable charger stored which so happened to be the most I've ever seen. It truly comes in handy when you're out and about. My brother love it so much that he constantly have to sneak it away from me from time to time when he's on the go. Charging it takes hours but my trick to it is to always charge it back up once I'm finished using it so that I'll never miss a beat if I have to go somewhere unexpectedly and just because of the person I am with doing things. To fully charge it up one bar is over 2 hours so once it's completely dead just expect to have it charging for a while but what I do in this case is to let it charge while I sleep so by the time I'm up its either fully charged or almost there. Even if I forget to unplug it, with the built-in overload protection it stops charging once it's at full capacity.

    This charger is one of the better ones. It can charge an iPhone 6 Plus about 7 times if the iPhone is dead. However I find that that amount changes if you use the phone while it's charging. Just be aware that this charger is bigger than most. It's about the size of a dvd case if you cut off an inch down the side.

    The charge holds excellent and can be connected to other sources at the same time without draining power from the other electronics. Looks good, charges excellent and is not heavier compared to other devices. I have used this item in airports on the plane and at the beach. I am never out of power wherever I am.

    We were looking for a portable power supply to keep our devices charged while vacationing. Between 2 cell phones, a tablet, and an iPad we got exactly what we needed. We were able to keep our devices charged and still enjoy our vacation.

    I would recommend this especially for the Pokemon Go players. Bought 2 of these chargers for the great clearance price. One for my 2 Grandsons to share for thier Pokemon hunts and the other for my Granddaughter to keep in her car since her vehicle charging ports do not work. Have had 3 different phones connected at one time for a charge and still plenty enough power left in charger. We went on a 8hr adventure downtown and not one of the 3 iphones died because of having this charger! Charger can be recharged and hold that charge for 2 weeks or more while not in use. Wish I had bought 1 more, my daughter wants one! My teenage grandkids are very satisfied & happy with them!
