Customer Ratings & Reviews

I was happily to find a charger that was slim, light weight, and modern, that connected and worked without the need for instructions. I've carry it with my cell phone and I have no more fear my phone would not have a sufficient charge. I like that it has an LED window indicator showing the charge remaining, and 3 UBS outputs for multiple charging.

Best way to keep your cellphone charged at all the time!! The best thing is that it gives you more then just a single charged!!

I like this charger a lot, I recommend it to everybody.

In the past, I have had several portable chargers, most of which, took a very long time to charge because of the lower mAH's. Not so on this one, not only does it have the higher mAH's but it has a percentage meter on the front telling you exactly how much power you have left and when to recharge. It is also supper fast when charging. For me it was worth the price. It is a little heavy but to me it is a trade off, between a small amount of extra weight vs the time it takes to recharge my devices on the go.

Used this charger on recent trip to dc and wanted to make sure both of our phones were charged for picture taking. Charges both phones quickly. Says you can get three full charges before needing to charge device but we got five easily. Only two minor caveats: the cords that come with it (only one) are so short you cannot use a phone while it is charging so make sure you have longer usb then you can leave charger in a pocket or in a purse and use your phone easily without having to hold charger and phone. Thankfully we figured this out before the trip so no problem. Second caveat is when the charger does need recharging make sure you will not need it again as it takes forever to get back up to a full charge! It was fine for us as we charged it overnight back at hotel and just used regular usb wall chargers at night. This charger was well worth the money and will be used again on our camping excursions.

I've purchased several battery packs from Mophie's to bargain ones and this battery pack really works. I love the easy to read LED screen that let's me know how much juice is left. With a Note 3, I can get about 3.5 charges out of the pack before it dies. It also has multiple USBs to charge up to 3 devices at once. The best part is the 2.1Amp USBs and how quickly they charge your devices. It's pretty dense and heavy for its size but it seems to be made well.

I purchased this as a back-up power supply for extended periods away from plug-ins. It will fully charge my iPhone 5S using only about 10% of the battery available capacity. It will also charge my iPad, my iPhone, and another 2 amp device simultaneously. It performs as advertised as far as I can tell. It also holds a charge well during periods of not using it, and it doesn't take long to fully charge when it's been depleted. I've been using it for around 4 months now and don't have any complaints.

After reading the reviews on the REV Portable Charger, I decided to buy it when it was on sale at Best Buy. First, I love the digital display that indicates the amount (percentage) of charge remaining. Second, the 12,000 mAh unit I bought has enough juice for about four charges. Third, this unit charges my iPhone quickly when no electrical outlet is available. The only drawback I have found with this unit is the power button. It won't stay on when I have my iPhone plugged in to the charger, UNLESS I use a certified Apple cable. It doesn't seem to work with third-party cables. Not sure if this is a problem with Apple's proprietary cable design or if it's a problem with the charger. Otherwise, I love the charger.

I was so happy I purchased this! It's a little on the heavy side, but I love it. It's a little bigger than my phone (Samsung Galaxy Not 4). It has helped me keep my phone charged when I'm taking pictures & videoing at drag races all day. It charges quickly & it will charge your phone multiple times. I love that it has a display on the battery to let you know how much charge it has left on it. I would highly recommend this.

This charger charges whatever I plug into really fast whether it be an I phone, iPad, or laptop. Since I don't need this charger for everyday use, I was fine even if it is a little heavy. This is very useful specially when travelling because the battery lasts long.

While My use of this power bank is unusual it works great for my needs. I use this to power a small computer known as the raspberry pi and a small 9" monitor known as the HDMIpi. I needed this to power the system for at least 6 hours, well it does so I'm happy. If you just need this to charge a cell phone or tablet it will charge those devices multiple times before having to plug it back in. The best part is the power bank tells you how much power is left in the bank (by percentage) letting me shut down the system if its getting low. This isn't a matter of would buy again, this is a matter of will buy again for other applications.

I got this charger on sale just for $14.99. This is the best deal on the market for 12,000 mAh chargers. The BestBuy did not give the correct dimensions and weight for the device, though. It is actually LxWxH 5.75x3.125x0.625 inches. The weight is 11 oz. It works really well! I got another one for my son who uses USB devices extensively as he travels.

Great option for charging multiple items! You can charge 3 items simultaneously and even Charge the REV at the same time. I have a 5.5" smartphone with a 3000mah battery and can get 3 full charges out of the REV. Love the digital readout of remaining charge too - remains on whenever charging, flashes when recharging the REV. Also Automatically turns off once you are done charging your device. I've had many portable batteries, but none with the intelligence built into this one!

I needed a portable power supply to charge iPhone, iPad, and cell phone that had sufficient amperage and which had an indicator of charge status. This unit works great. The display indicates when the internal battery is charging and provides a digital display of the percent. of charge. The only drawback is the cheap cable. I replaced the cable with a reliable oem Motorola, Lg, Samsung phone cable with a mini usb to Apple lightning adapter. The case is slim and durable. The multiple USB ports allows simultaneous charging of multiple devices.

Excellent on to go charger! I can fit the power bank, cord and wall charger USB adapter(not included, I cannibalized a poorly functioning charger from an old phone) into a sunglasses sleeve, which allows this convenient product to be kept in my purse for long days when I know I will need it or, even better, emergency use. I purchased this item specifically for a trip to Disney, followed by a week long convention where there was to be little access to charging facilities, and the power bank more than delivered. We charged multiple phones multiple times throughout the Disney trip and recharged the unit whenever we stopped for a rest or to eat. The recharge rate was better than I had read in research when I was looking to buy this product, so that was a pleasant surprise. The rate at which the power bank depleted by charging phones was also better than anticipated. This product held its own through weeks of heavy use and is still performing like new. I rely on this product as a backup charging source and carry it with me everywhere I go. Highly recommend this product!

Upsides: I bought 3 of these. In general, they have performed admirably. They have no problem charging multiple units at once, and can maintain the charge level on a phone even when using high-drain apps like that one with the Pokemon. One unit can easily keep 3 people on social media through an entire minor-league baseball game. Charging my G4 takes about 90 minutes, roughly what it would take using a wall adapter. I can easily charge my phone 3 or 4 times without recharging the power pack. Downsides: It's slightly bulkier than a large smartphone, and noticeably heavier. This is hardly surprising, given the battery capacity, but you'll want to stow it in a bag rather than slipping it into a pants pocket. Also, Given the battery capacity, you probably won't be surprised to know it takes a long time to recharge the battery. Expect 8-12 hours for a full charge-up. Of the 3 units I bought, one failed to turn on after about 2 weeks of use. This brings me to my only real complaint, and the reason for a 4 star review rather than 5: Best Buy will not exchange a defective unit in the store. Instead, you have to call the manufacturer's technical support line. They will tell you to scan or take a picture of your receipt and email that to them, at which point they will mail you a new unit. This is poor customer service, and unnecessarily complicated considering the store literally has replacements sitting on the shelf.

This works great for charging my S6. It charges it very fast and you can get many uses before needing to charge it again. I will say it does take awhile to charge this power pack up to 100% though. Overall, I am really happy with my purchase of this.

With my samsung s6edge i can use it 4x before it dries up. Its very easy to use and charges my phone faster than expected. The only problem is that its a lot heavier that it looks but its okay.

This is a great battery pack that will give you a super boost and fully charge very quickly. Great product, i bought it 3 months ago and i haven't had a problem with it. I'll carry it from time to time in my backpack just in case.

After using this twice, I am writing this review. This charger holds a charge and powers my phone at a good rate. I also like how this charger does not get hot when it charges. This is an excellent power source when traveling on a plane that does not offer charging.
