Customer Ratings & Reviews

I've purchased many chargers, but this one offers the quickest charging time. My only reason for giving it 4-stars is because it's heavier than I would like.

Works great. Except when it doesn't. Sometimes it shuts itself off and doesn't finish charging. Not sure if it's a function of one of the three ports. Haven't figured it out and instructions are minimal.

I was looking for a "portable backup Generator" in the field of mobile phone chargers & I found it - this REV one is an Excellent Product! I was assisted & directed to this choice by a Best Buy Associate - to him I'm grateful. The REV lasts thru 9 - 12 mobile charges. It's so many, I'm happy to say I lost count! I like the digital # readout of charge % remaining.

I have charged 2 cell phones different models at the same time and run a iPad for a meeting off it. I couldn't be happier with it.

This is an awesome charger. I have taken it on several international flights and it works great to charge my iPad and iPhone on long flights that do not have a charging port by the seat (economy class seat :-( ) I even take it along on domestic flights and driving vacations so that I can have the extra ports for charging phone, tablet and camera.

It was already charged when bought, was able to use on IPhone right away and only took a few minuets to charge phone. Also was able to charge Ipad pro which took a little longer, but was still able to use it with in about an hour. This device works great with any phone or tablet.

I have fully charged my iphone 3-4 times, AND charged my IPad up to 2 times on one charge, and have never had this thing empty yet! When it gets below 40% I usually put it on the charger overnight, and I'm ready to go when I wake up. Love this item, it's the best I've ever had.

Very functional and easy to use. Charges my iPhone perfectly.

Powerful portable battery that provides multiple charges for a wide array of devices. I bought this to charge my iPhone 6 for an international trip I was on for 12 days, and it still never fully depleted its battery. Just remember, when recharging the portable charger, allow more than 1 hour as it does take awhile to fill back up.

My little nephew keep using my mom's tablet and draining the battery completely this product has allowed my mom to recharge her phone and tablet at the same time while she's playing games. Since the purchase of this product has made my mom very happy and anything that makes Mama happy has to be a good product love it love it love it

This battery is something that everyone should have. As a matter of fact i have given this as a gift to my girlfriend, her mom, and my sister. Ive bought the same one because the price per capacity is the best on the market. Also, the built quality is great and its sleek looking. This has a measure of how much power is left too.

Great portable charger for the money. Very sleek design

This thing is the size of a small tablet and significantly bulky but, it's great to have around the house as a back up for emergencies or power outages. As time goes on these things will get smaller and hold more power but, this one works for me for now!

I purchased 3 of these power banks in different capacities and am absolutely amazed. They are super sturdy and not made of cheap plastic like other brands. The digital readout is a must have and is very accurate. They retain their charge well. I would definitely recommend these over any other manufacturer!!!!

I took this charger with me on a week long vacation and it kept my iPhone charged for most of the trip. I charged my phone in the car a few times, but aside from that, it was mostly charged on the power bank. The only thing I can say against it is that it takes quite a while to charge the device itself.

I found this to be reliable and useful when heading into the realm of wilderness for camping. For off-grid recharging it requires a substantial solar collector.

I purchased one of these for my wife and then decided to purchase them for the whole family. They are perfect if you travel a lot or are a road warrior. Lots of power for phones and other portable devices. No problems to report and the charge last for months. Good digital readout for the % of battery left.

The Rev works excellent! It charges your products very fast. The only reason I gave it 4 stars is because it is heavy.

It's pretty big as portable chargers go, but that's due to the large amount of power. It holds it's charge well, so you don't have to constantly make sure that your backup supply is full. Having the digital power meter on the front is a great feature, you can easily see how much of the charge is left.

Even with all the other positive reviews, you need to be wary of this product. Upon opening the box, the unit has a charge to recharge your electronic products. Unfortunately, that will be the only full charge you will get. No matter what I did, the unit would not fully recharge. The highest was 37%. There is no tech support online and phone calls just end up in a voicemail. The address on the manual is for PNY, but they don't support REV. Geek Squad was also unable to assist with the charging problem. I guess it's back to Best Buy for me.
