Customer Ratings & Reviews

What I like most about this charger is the stow away USB and how thin and easy it is to carry around while using my Galaxy Note 3. Plug in the USB and back the charger flush with phone to make this convenient plus easy to hold onto, even with such a huge device as the GN3. (I admire its look as a matching accessory for the GN3 but $60 for 3100mAH seems pricey. I've spotted this same unit selling for more than $20 less on the internet though it seems doubtful you'd have the same support from third parties as with Best Buy). This charger is/was offered in two colors (black or white) with the same finish and faux stitching as the GN3, if you prefer that look, and comes with a small, easy to store charging cable for the device. This charger has a percentage level indicator that's not precise, though still useful...simply locate the 'button' on that side of charger and press it in. These are the levels per lights: Blue light = 100-80% battery life; Green light = 80-20% battery life; Red light = 20-5% battery life; Red blinking light = 5-0% battery life.

I bought this portable charger for when I went to game 7 of the stanley cup finals between the washington capitals and the new york rangers. I knew that I was going to a great experience and would be taking plenty of pictures with my samsung galaxy s6 as well as videos, and that my battery would be drained fairly quickly by doing so. Considering the game went into overtime and I had enough juice to get home I was very pleased with the result of this battery charger. Also portability is excellent.

My battery kept running down on long bike rides. This has been a godsend. It's thin and small and charges fast. When my batter is down to 10%, this will charge it to 100% before it runs out. I highly recommend it.

This is a well performing back-up battery for Android devices. It is very thin and lightweight, fits in any pocket. I especially like the built in connection cable that pulls out and retracts when finished. There is no chance of leaving the house without the cable. It charges my Android phone and Galaxy S2 Tablet with power to spare. Good item, excellent price.

Initially, I was taken back by the price since my friends had portable chargers which were far less expensive ($12-$15), but in the end you get what you pay for! I have no complaints about this charger. It charges itself rather quickly, and holds the charge if i don't use it for a few days. It also quickly charges my phone which is a huge plus. My friends which had the far less expensive portable chargers constantly had problems, and their chargers was not able to fully charge their phones back to 100%

The portable battery pack is perfect for my needs. I ride a bike aq few thousand miles a year. I use the APP Map My Ride and the GPS component of this app kils the phone battery. After my ride I may not be able to be tied down to the house or the car to charge my phone. The battery pack is portable and it allows me to recharge my phone in a very convient way.

I love this battery charger. I have 2 other chargers and they are just fine but they do not beat this one. This one charges my Galaxy Note 3 fast. It is thin and easy to stash in a pocket or wallet. I can also use the phone while it's attached without having a charger hanging from the bottom of phone. This one I just put on back of phone while I talk and it is just the same as holding the phone to talk. No one is even aware it's there. So It is the best I have found. Pros are its flat and lays behind phone while I talk. Charges my large (phablet) phone fast and completely. It is thin and light enough to go in my pocket, wallet or purse without any bulk. I would not only recommend but I'd buy one for a gift.

this is a nice unit to have is a backup for when my battery goes dead. I use it when I'm not able to get to a charger can usually get about two charges out of it.I would recommend this as a backup. does not take too long to charge.

I purchased this charger for when my battery is running low on my Samsung Note 4 and I am not close to a plug or my car charger. It does take time to charge but the peace of mind knowing I have it, makes it worth every penny. It charges my phone to about 75% in an hour. I keep it in my purse and it charges as I work or shop etc. It doesn't get hot. It is slim in design and charges better than a Mobie for the same price. Highly recommend.

I love how light and efficient this device is. I can charge my phone in my pocket while I'm on a job or walking around and not being anywhere near a charging station.

An awesome buy, got this item with a best buy price match, best purchase I made in a long time. compact enough to carry in pocket and enough of a boost to get you buy. Quality product.

I purchased this portable charger for a vacation I was taking because my phone uses a lot of battery. I was impressed with the speed it charged at and the sleek design made it fit comfortably in my pocket.

Have used this to charge a Note 4 from 47% to 100% within an hour. Have charged the phone twice on one charge - so far. Like the slim compact design.

This is Excellent for people always on the go!! Fast charger and convenient.

A friend of mine has a portable battery pack, which I have used, & it seems to charge a lot faster & supposedly longer. He claims to get 8 phone charges when his pack is fully charged. This Samsung battery pack is 3100mAh & his was 3300mAh. Either way, it doesn't appear to hold a charge very long, nowhere near 8 charges, & not a universal charge port. My wife & i have Androids so it works fine but not compatible with Iphone or the ability to hook up a USB connection out. If it kept its charge longer, I would give 5 stars because it's small & charging cord is built into it, so no extra cable required.

Nice size for packing, and good capacity. Good buy for the money.

This back-up battery is important when you are traveling and run out of power. However, I did not buy it for that reason. I bought it so that when the power is down I will still have power to send texts and make calls. Recent storms emphasize the importance of having one of these devices.

I bought this on the recommendation of my sister. It is a nice slim size. I just wish it charged my phone more, only charged my phone to under 75%. I thought with the specs being alot more than my old one it would charge it full

Very good battery for powering your electronics on the go. It does take a few hours to charge, and I do recommend that you use all of the charge before recharging, but it is great to have for additional power

I am a long time android user. This is my third tablet. I had the galaxy note 3 pro and was very happy. Unfortunately, it was stolen. This tablet s is the current equivalent. The screen is incredible. Very crisp and bright. Speed is great with the dual quad core processors. Battery life is better than my old tablet and this one is lighter. In my opinion, this tablet is the equal of the iPad without the lock to apple. If you want a high quality, high performance device and are willing to pay the price, this is one to get.
