The EasyAcc Ultra-Slim Power Bank definitely exceeded my expectations. I was originally looking at a charger from Anker for my wife but a tech blog I followed pointed out the price (w/ promo code) on this little guy at $4.99. Man was this a steal! I charged it up to 100% and had it charge my Sony DSC-W80 and my PS4 controller from 0 to 100% on a single charge from the battery. The little guy still had juice! I'm a firm believer in you get what you pay for but that's not the case with this battery pack, I got waaaaaaaay more than I paid for...EasyAcc Cable 4000mAh Power Bank Ultra-Slim Portable External Battery Charger Built-in Micro USB Cable for Smartphone-White and Red

Excellent way to keep your phone charged.

Lightweight and super fast 2 amp charging. This battery has the built-in cable which is very convenient. It does NOT need a special charging cable nor will it turn itself on when bumped around in your bag. Simple and elegant. I have recommended this to several people.

Wonderful and Convenient

I purchased two different portable battery charges for a trip and this one was by far my favorite. I love that the cord is included and tucks right into the device. It's very convenient. Perfect size. It charges fast and without getting too hot. Highly recommend!

Slim and Portable Power Bank for Samsung Note 5

Very slim power bank. I use it for my Samsung Note 5, it does hold enough power to charge my Note 5 from 10% back to 100%. I am able to fit power bank into my jeans' pocket along with the phone. Worth Buying.

Good, but should include spare cables..

Very good product.
I always buy Power Banks with Built-in Micro-USB cable and this is the best so far.
The 2 reasons why I don't give a 5 star are:
- They should include 2 spare red cables. The cable gets damaged over time, what will force me to carry an extra cable.
- the micro USB side of the cable does not need the metal connector to fit so tight. Only the Red Rubber around the metal connector needs to fit tight. The risk of damaging the metal connector is high and this makes it harder to use the cable.
If those two problems were solved, i would have given a 5 star!!

Nice external battery, good value for a great product.

Very nice, bought it for my sister to use because she always forgets to charge her phone. I like the option to see how much juice is left by tapping the side. A great value!

Good Power Bank

I have had this product for a couple of weeks now. The battery is pretty big, I use it to power my Arduino, but I can also use it to charge my phone. It's enough battery to charge my iPhone 6s about 2-3 times. It has almost the same size as my iPhone, it's just a bit thicker than it, but still slim enough for my pocket. I don't need the cable thats built in, since I have an iPhone, but it would be very helpful for Android users. I rate this power bank five stars, because I didn't see anything negative at it.

Good little charger

This little charger is perfect except in one small way in that it doesn't pass through, I have an import car that doesn't charge your phone except when it's running and then when it's running this doesn't charge your phone. I found one that I'm going to purchase like that though that does pass through at a significantly higher price, but for what it does it's been very good!
