Customer Ratings & Reviews

A bit bulky and heavy, but seems to work well and as advertised. Great to know you won't be stranded without a working iPhone or iPad when normal charging stations aren't available or you're out enjoying life. Ability to charge more than 1 device at the same time is a plus, too - share with a friend and your family. :)

I was searching for an external battery charger, this is awesome, I could charge 8 full time my phone without any issue. Fast charging back and great performance, it really fast charge 3 phones at the same time, I absolutely recommend this battery

I would have given this battery a 5-star rating except for the weight. It is a little heavy. But what can I expect from a battery that will fully charge my phone at least two times. It is a life saver (okay, a bit of an overstatement.) Let's say it has come in handy and saved the day for communications when I am travelling. I have not been sorry one moment for this purchase.

I got this item because I was going to travel out side the US and I wanted to make sure that I would be able to use my phone. I must have used it every day for 5-6 days with out charging it and it was great!! Its also a great produce for the price!! (it was on sale)

After my first big battery purchase made me return it due to problems with it, I ran into a guy playing Pokémon Go recommend it to me. It's been over 6 months now and I'm still very happy with this device. 3 USB plug ports, the battery lasts FOREVER*.

Needed a charger and while there this unit was the best bang for the buck. Sure enough, it fit the bill and has done a great job. Ended up purchasing two of them.

It's the best power bank out there and its cheap. It charges fast and has a button on its side to see the power level, it has 3 ports to charge what ever I need and believe it or not it actually lasts quite a while once it's fully charged

I love this charger, charges my phone very fast! Can charge up to three phones at the same time or anything else I want to charge have nothing bad to say about it works great

This charger kept a Samsung Galaxy and iPhone S6 charged all day with a lot of juice remaining in the charger by the time I got home. It's too big and heavy to keep in a pocket, but it fits easily in small bags or backpacks.

It has the power you are looking for to have your cell phone or other devices run for a long time without interruption. What I don't like is the weight. This product you can relay on to provide you the long use like when you travel or being on the beach. I always carry it with me everywhere.

Good for the price, but wish that the ports were quick-charge. The capacity for the cost is unmatched, as a Mophie with that many mAh would cost at least double, but the lack of a quick charge makes it incapable of charging larger power consuming devices like the 12 inch MacBook and it charges my iPad Pro. But it does so very, very slowly. Overall I would say this is an awesome solution for someone who needs to charge multiple phones multiple times, like for camping.

This battery has amazing capcity at a reasonable weight. I've taken it backpacking and on backcountry hut trips. Charges quickly relative to its capacity. Just love it -- highly recommend it!

This is a great product compare to the higher of cost of chargers, I'm in the military and I take it to the field with me and it works great.

I had been looking for a portable power source for a while as my wife needed one. The Insignia 20800mAh Portable Power met my needs so I gave my wife my old 4000mAh unit. She preferred it because it was small. This unit is very large but has the most power (mAh) available. I will carry it in my backpack, so size isn't a problem. It will also power 3 items at once (phone, earpiece, and another for any other item I might need to charge).

I absolutely love this portable charger. I have an iPhone 6 Plus and not only is it quick to charge up my phone when I need it, it gives me a solid 8 charges. It's really useful when my friends and I are playing Pokemon Go, and we need a little pick me up. I can let 3 people charge at one time which is a plus. It takes a little while for the actual charger to charge so I would recommend trying to charge it at night. Works for me

All systems are go here Cap'n. This thing has a serious amount of juice and keeps things going when its needed. First one sits in my bag to keep my tablet and phone charged if needed during class or travelling. My tablet is what I used to take notes on and is a must for my college classes. Couple things Ive found from usage: - This guy seems to live up to the numbers on the box, My note 3 reports it hits its max input of 1.8A charging using the supplied, but hardly used short micro B cable. (cool but I have a longer one, dont skimp get a good cable to keep fast charging). - The brick you use to charge this thing will be very important, cheapo gas station bricks will take forever as they will do around 500mah, you do the math on a 20,800mah power pack. Your stock phone charger should do the trick, the rocketfish platinums are a great alternative. - Not sure if this supports quick charge, but neither does my phone from my understanding (usb 3.0 is just crazy like that.) - durability has yet to be tested, I don't plan on slamming my investment on the pavement, but durability does not seem to be a problem especially at this price point. Many much more expensive chargers cant take much anyways before they quit as well. In terms of performance, it took two of these to last a group of 8 people with cellphones and one tablet to drain one pack and start on the second over the week we spent camping. Not too shabby.

There are a lot of choices out there for portable chargers out there. This one is great for when you have the space for a big battery and you can't beat the price.

This is my best portable charger! Charges fast and lasts for several charges per phone

and a little heavy for normal use, takes a while to charge, but also lasts quite a while when just charging a phone or earpiece. It's good if you don't need to carry it around with you.

The charger holds a charge for a very long time. The only negative is the weight is too much. If it is in my purse, it makes the purse too heavy to be comfortable.
