As an engineer I test every battery I own so, naturally, I couldn't wait to put this one through its paces. It has some positive qualities but they're completely overwhelmed by the lousy capacity.

First the good:
* Using both micro-USB inputs (provided each is coming from a capable supply) really does charge this battery quickly. Two 10W chargers brought it to full in under 8 hours.
* Each output will deliver over 2A, even simultaneously. Understandably the battery gets warm when you do that.
* It makes a great charging distribution center. My family, with four phones, three iPads, ereaders, headphones and various other devices, took it on vacation and instead of having to hunt for wall outlets (leaving things plugged into random places in the hotel room) we used a good 10W charger to power this and, overnight, it charged everything else. In the morning our gadgets would be full, this would be around 50% and while we were out it would come back to 100%, ready for the next night's work. A multi-headed charge cable makes it even better.
* It's heavy but that's in the "good" column because it's not as heavy as I was expecting. I had it in my backpack for a while and didn't notice the extra weight. Of course that's probably because of the severe downside...

And that downside is:
* Delivered capacity is only about 70% of the 20000mAh stated. I've charged this battery to full and run it down completely with a good power meter and got consistent results of 13739mAh, 13703mAh, 13828mAh. Originally I gave it two stars but see the update for more detail.

Hi,
This is my review for the product listed on Amazon as:
EasyAcc Monster 20000mAh Power Bank (4A Input 4.8A Smart Output) External Battery Portable Charger for Android Phone Samsung - Black and Orange

I received this product a couple of weeks ago and have used it a few times to provide a detailed review. I have included a set of photos that I have taken in case anyone is interested.

UNBOXING AND OBSERVATIONS:

The product comes in a very simple cardboard box that has no graphical designs on it. If it was in a retail store, I would’ve passed by it. But the presentation on the Amazon product page is what sells and when receiving this product box, the intention in my opinion is to use this product out of the box and discard the box.
The top of the box has the brand name and model number of the power bank. The right side had the serial number barcode. The bottom of the box has some feature summary and example of compatible products for this power bank. Basically, any mobile device that uses a USB Type A connector to charge the product can be used with this power bank.
Upon opening the box, I found the power bank was wrapped in a plastic bag to protect it from dust and fingerprints by the factory or shipper. In taking that out, I found the User Manual underneath with 2 micro USB cables that were in a hidden compartment that had to be lifted out of the layer of cardboard in the interior. Everything was tightly snug when packaged.
The first thing I recommend on doing is reading the user’s manual to be aware of how to use the product and what it can and can’t do. Some notable information includes:

Smart Technology is built into this power bank. What that means is that while the total output is capable of 4.

As I went out to look for large capacity, portable device-chargers, I came across the EasyAcc Monster 20000mAh Power Bank. Wow! That is a lot of power.

As you can see from the video, the Power Bank is obviously larger than the smaller, lipstick style chargers that are so commonly sold today. However, you get 6-8 times more stored power with this device.

Here is my short list of pros and cons.
Pros
- Lots of Power - mAh translates directly to how many times you can charge your device. Each device's battery will have a certain number of mAh that represents its capacity. For example, the iPhone 6 is powered by an 1810 mAh battery which means that with this device I can recharge it numerous times (maybe not the 11 that you would think but more like 7-8 times). Just a side note, with all of these batteries there is some loss of power when transferred to another device, so you can't just divide the total capacity of the power bank by the capacity of your device. In my experience you will never get that many recharges but more like 65-70% of that number. Wow! This power bank has a ton of mAh.
- Numerous, powerful, smart ports - Super handy when you need to charge multiple devices at the same time. I've only used 2 at once but you have the option of charging up to 2 devices at once. The ports can detect your device and charge it at up to 2.4A ports; which means you get a faster recharge on your devices.
- Lights to indicate remaining capacity - I love that I can easily see the current charge of the power bank. There are 4 small lights (see video) that indicate its current capacity. Each light indicates ~25% of capacity.
Cons
- Heavy - Batteries weigh a lot and this is no exception. Not a big deal for the power you get but something to be aware of.
