Size Name: 5600mAh
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. The unit will auto-off after 1 minute if no load is detected.
- Two short pulses turn on the LED flashlight. It is relatively dim and only good for short distance illumination.
- Another two short pulses turn off the LED flashlight.

The EC Tech unit's battery status indicator is highly non-linear. Each LED 'ring' does not represent 20 or 25% of charge.

Size Name: 18000mAh-Black Leather Cover
Length: 6:03 Mins
EC Technology's 18,000 delivers good charging capacity as well as slick design. The leather wrapping breaks from the metal housing that most battery packs feature and instead uses a leather material that is not only soft, but also stylish. It provides a good surface to set your device right on the charger while it is charging. The size is convenient featuring a thin style instead of a blocky style. The leather is also nice in the winter time when touching metal is extremely cold and the last thing you want to carry around is a metal battery pack. The LED light features different modes (dim, bright and S.0.S. flashing) which is the first time I have seen this in battery packs.

It provided me with pretty good charging speed and capacity-wise it was slightly better than my 15,000 mAh battery packs, providing about one extra charge. Overall, it is a good solid charger with good speed. Definitely a top of the line product compared to others in it's range.

Size Name: 5600mAh Verified Purchase
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.

Size Name: 18000mAh-Green Verified Purchase
This unit, in green, seems well finished and solid. The bright green on mine is very attractive and stands out. Unfortunately, the one I received had (2) rather serious problems.

1. Charge Rate was lower than advertised. It would not charge my Samsung Galaxy Note 3 at higher rate than 1.0A on either outlet with either micro USB 2.0 or micro USB 3.0 cables that provide 1.8A from other portable battery packs that I own. The actual charging current was typically between 700 to 850mah. Data was recorded using Galaxy Charging Current app.

2. Irritating LED light that stays on while charging a phone or tablet - the operation of this light is not properly documented in the manual. As with some other battery packs, one must tap the power button on the pack for it to initiate charging your phone or tablet. The number of illuminated segments usually indicate how much charge is left on the pack. Then the light normally goes out by itself. That's what is documented here but not how mine works. The light stays on. Tapping the power button allows one to cycle between full bright, half bright, or flashing of the LED, ostensibly for use as a flashlight. Double-tapping the power button turns it off.

Why is #2 irritating? Imagine that one uses this battery pack to charge a tablet or phone on a long international overnight flight. With this one, the entire time it's charging, the bright flashlight is illuminated. Not a wonderful thing when your neighbor in the next seat is sleeping, or if you are intending to watch a movie on your device. If you tap the power button to kill the flashlight, the power stops flowing to the device that one is trying to charge.

I did contact the supplier, EC Technology and did send them screenshots documenting the low power output.
