Customer Ratings & Reviews

I was skeptical at first and bought this while it was on sale as a deal of the week item. I figured if the reviews were correct then what's an extra $20 for a portable charger. I didn't need it, but figured it would come in handy in the future when traveling to charge my iPad and iPhone. I went home, and like the reviews mentioned, it came fully charged. I took turns and charged my iPhone 6S Plus, my wife's iPhone 5S, our iPad Air 2, and 2 of my friends iPhone 5S phones all with less than 20% power a piece. In about an hour all devices were fully charged. This portable charger still had 56% battery life on the digital display. I couldn't believe it. I then went back to Bestbuy the next day and bought 4 more of these chargers. One for my wife and the other 3 for my close friends. This charger does take a good bit of time to charge back up. I recommend charging it before sleep and then you should be good to go for most average use for about 3 to 4 days of regular charging for similar devices that I have mentioned.

This Product works great! and it pretty quick and has 3 ports. The coolest part is the LED display that lets you know how much battery you have left. Its kind of bulky and on the heavy side but that just means its got power and not like the other ones that are light and take forever to charge.

Charges my phone and devices very fast and last a long time. I can charge my phone fully several times

To start off I thought this was a little pricey but after I started using this to charge my electronic devices and see how fast and efficient this was I was really happy I bought this. You can charge Android and IPhones, and iPad without no problem easy to use and charge

Great back up, led indicator for remaining power, Slim case for space saver when travelimg

Very good devise to have when you are out all day. Great when you have multiple devises.

I use a very battery heavy smartphone game called Ingress. I went out all day and played connected to this batter. I mean all day. Screen on all the time, GPS active, never touched the phone's battery. Still had 50% left on it at the end of the day. I charge it on the weekends now and leave it in my car to get a quick charge for not just my phone but my ecig and smartwatch as well.

I travel a lot and use my phone on the job, running work related apps in addition to normal calls, texts, etc. When I'm out of the vehicle or office, this is great insurance. I never worry that I will end up with a dead device. For what I do, I feel like this would keep me alive for a few days IF I was unable to connect my phone to the wall or car. I have never completely discharged it, but my top off charges seem to take a reasonable amount of time. Not as quickly as I'd like, but I wouldn't consider it slow. Bought mine on sale, so there was nothing close in terms of juice per $. Seems well built. Love the LCD display of capacity, and multiple charging ports. Fairly hefty, but not something you couldn't keep in pocket or purse. This may not be right for all users, but for the scenario I've described, it's darn near perfect!

Great product. Stores easily in a purse or pocket. It charged my phone up to 100% just as my USB rapid charge does. Maintains charge percentage life while not in use and the charge percentage does not decrease until a product has been charged.

The 12000mAh is physically rather large but so is the capacity. Works great for charging phones and tablets. I can get between 8 - 10 partial charges into my iPhone 6Plus with this thing! A feature I like (some might consider it a drawback) is when your device hits full charge the Rev turns off. This charger is a great idea for travel.

The charger is fast and can handle multiple charges on one charge.

Store associate recommended. Charges quickly. Easy to transport.

Charges fast and can be used multiple times without recharging.

Digital display is awesome charges fast and easy great product

Easy and convenient to use. Several charges for iPhone 6

This battery is just what I needed. I can get about 4 full charges WHILE USING MY PHONE. I have the iPhone 5s with about a 1500 mAh battery in it. I have had no problem charging two phones at once, either.

Love that it can charge more than one at once. The digital readout is very convenient too. Charges quickly with a bunch of charge left over. I like it so much I'm going to buy one for my husband.

Charges my phone about 3 to 4 times. Keeps a charge at 100 percent till usage.Catch it when its on sale. Very good product to have when you are out and about and can't charge your phone any other way..Definitely recommend,also have another one that is 4000 mAh and is a Rev.

A little heavy, but this portable charger is great, I can charge my phone many times or I can charge my tablet twice and still have some juice left. Very affordable.

Purchased on sale, this portable charger is fast and has many plug in options, not to mention the high capacity battery. The digital readout is large and easy to read.
