By NLee the Engineer HALL OF FAMETOP 10 REVIEWER on December 1, 2013
Size: 5600mAh
[Important Note on May 1, 20015]
My review below was written for the "ET Tech 5600mAh Power Bank" back in Dec 2013. Unfortunately, Amazon loves to move reviews and products around. Now my review appears under the product page for "EC Tech 18000mAh Dual-Port Power Bank". I don't like this practice either, as it creates confusion for readers. As usual, use caution when shopping on Amazon.

==== Original Review follows ====

From the outside, this EC TECHNOLOGY 5600mAh External Battery Pack looks EXACTLY the same as another power bank I have previously tested, the PowerBot PB5600. However, based on my testing, they have very different control circuits, and contain different capacity batteries inside.

I tested the capacities of both units, using the same method, with a 5-ohm power resistor as load.
- The PowerBot unit delivered an average power of 4.91W for 183 minutes. This means a total output energy of 15Wh
- The EC Tech unit delivered an average power of 5.08W for 210 minutes, which is equal to 17.8Wh
(see the "Output Power vs. Runtime" chart I uploaded to 'Customer Images section for details)

Assuming energy conversion efficiency of 80%, I can estimate the PowerBot unit's internal battery to be 5060mAh, or 10% lower than advertised. The EC Tech unit's battery is estimated to be 6000mAh, or 7% higher than advertised.

Notes on the control for this EC Tech unit:
- A short pulse on the power button turns on the USB output power
- A long press over 5 sec turns off the USB power.

So far this battery has meet all the requirements I expected in a portable battery source. The light is not that bright, but I did not purchase it for that option. It is good enough if you need to find something in the pitch dark or use as a book light. I found that the battery itself provides a faster charge to my Samsung phone versus the wall charger that came with the phone. I like the ability to charge different devices with the accompanying plug-in attachments.

this is an excellent product, and I would not hesitate to encourage any of my friends to purchase this item. I was able to charge 3 10 inch tablets and my smartphone with a single charge! I had other banks, and was lucky to be able to charge one of my devices before the charge ran out. I did have an issue which I requested support from EMC, I was impressed by the quick response and there enthusiasm to solve my dilemma.

Got this backup charger because it is cheaper than Anker brand and looked exactly the same. Probably came from same OEM manufacture but with different company label.

The item came a little scratched on the bottom side. I checked the package it was newly sealed and not an open package. But i was still a little nervous and decided to test the charger for a few rounds.

I charged up the charger to full before I started using it on my Samsung Note2. From empty to full charge took 8~9 hours with my Samsung charger. Used the connector that came with the charger to connect to my phone. The charger charged my phone about the same rate as my phone charger if not faster. I tested about 5 rounds and the fully charger is able to charge my phone about 1.5 times.

You can charge the charger and use the charger to charge the phone at the same time. Charger will take a longer to charge up.

The light is good when you are trying to charge the phone in a completely dark room, does not expect it to light up the whole room.

I deduct a point for the cosmetic scratches but otherwise worked as promised. Will update the review if anything comes up in the future.

I got about 5-6 charges on my Moto E which has the tiniest battery out of all the smartphones. There is some efficiency loss because of the leds it has to light up and some on the internal circuitry, but it is minimal. It is slow to charge your phone and it doesn't seem to quite get it completely back up to 100% (usually somewhere in the 90's percent). I like it because it will keep me out of trouble especially in airports when the only outlets they have are already being occupied by someone else. When I'm somewhere that has a real power source then I will use that instead.

Size: 18000mAh-Black
There are so many external batteries on the market and many are simply too expensive, don't have enough power to supply even one recharge of a phone or tablet, are too heavy or poorly made. This ECTechnology external battery has some surprises.

At 18,000mAh of battery power, it is at the top of the power game. I have only seen one other battery at 20,000mAh and it was more expensive. This is a very fair price. Considering that it can charge your phone (I have an iPhone 4S) about ten times and a tablet (I have an iPad2) three times, before you need to recharge the device.

It also has two ports (which is now standard) with one at 5V, 1.0A and the other at 5V, 2.1A for a slightly faster charge to your device being charged. If you do charge two devices at once, a full charge will take a bit longer than if charging just one. As a nice novelty, it has 3 LED modes: SOS mode, power status mode and highlight mode. The ‘pindicator’ shows power levels in 25% increments.

The size is BIG. It is exactly 6.6” x 4.7” x 0.5” inches and weighs 1 pound-2.4 ounces. It would complement a large Android but it is not the kind of battery you can slide into a pocket. It is meant for office or briefcase use.

I always recharge when it gets below 20%. It takes about 3-4 hours to fully charge. Overnight charging is the best way. All external batteries claim more than 500 cycles of charging but that would take a few years to use up. You've have to recharge it every other day for almost three years to get to that point. This also the first external battery that advises against charging and using your device at the same time. This can evidently lessen the number of battery uses over its lifetime.
