Device was charged via a 900mA charger during 1st session. This took about 9 hours. The flashing LEDS were helpful and they look nice. My wife used to to recharge first her iphone and then her ipad. This worked and i think she got 3 charges on the iphone and 1 on the ipad. I then recharged again on the same 900mA charger. It was fully charged by the next day. At the end of the day she connected her ipad and in the morning the EC Tech battery was dead and the ipad had only 41% charge, up from 19%. I have tried recharging EC Tech via the same charger and the blue LEDS no longer scale up the first LED blinks constantly. I also tried via my pc motherboard ( ASUS Rampage IV w/ Corsair TX 750, USB 3+ with 1500mA) with the same results. The battery could not have been low long enough for the lithium to bond to the anode and refuse to intercalate. I will send back 1 time and then update the review, I have owned several excellent products that the inital purchase was a lemon. It may have been to good to be true deal, but we can always hope can't we.

Color Name: blackSize 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.

Color Name: Black&RedSize Name: 22400mah Verified Purchase
After reading all the good comments and reviews on EC TECH power banks, I decided to give the 22400mAh one a shot. Im not sure if I received a faulty set but this power bank that I received is full of issues.

I charged this power bank overnight upon receiving it(that's more than a 12 hour charge and the LED lights indicated that it was at full charge) so I highly doubt that the issues I have is due to lack of charge.

1) It only charges my Galaxy Note 3 to 96% and then stops charging it completely. Tried the provided cables and my own, same problem. I used my phone a little to a battery % lower than 96% and tried charging again and viola! Once again it only charges my phone to 96% and then stops

2) I tried using this to charge my Note 3 official extra battery kit. it charges for a few seconds and then stops. tried stimulating the power bank by pressing the "charge indicator/led flashlight button" and it charged the kit once again for a few seconds and stopped the moment the led lights went off.

3) Tried charging 2 devices at once with the 2 usb ports, my Note 3 and a Cowon Z2 MP3 player. It only charges for the few seconds that the LED indicators were on and stops the moment the led indicators went off.

Once again, I do not know if my product is faulty.

EDIT: I contacted ECTECH about my issues and was promptly replied by the friendly staff who helped me through the troubleshooting.
They had even offered a full refund via amazon or an exchange to another model when it was affirmed that my unit had issues. However, shipping back the item for a refund/exchange meant that I had to pay a lot for the shipping and the understanding manager agreed to give me a full refund without returning the item! This is what great service is all about! 5 Stars for a great company that values its customers!

Color Name: Black&RedSize Name: 22400mah Verified Purchase
Absolutely love this product! I keep it in my backpack that i take to work and I'll be honest, I've only charged this thing 4 times since i bought it in November due to the capacity. I have a Galaxy S4 and this device holds enough juice to charge my phone from roughly 20% to a full charge on most work days for 2 weeks before needing to be recharged. As far as charging speed, I've owned another pack that was faster but not by much. Average charge rate for me is roughly 3% every 2 mins. Put it on for 30 mins and I'm up about 50%, an hour and I'm fully charged from 5%.
One very nice thing about this product is the two usb ports. I'f you travel, you can charge your phone and tablet at the same time with no real loss in charge rate.
Biggest thing though is the capacity. 10 full charges for a GS4 or 10 for my nexus 7 when the EC Tech is fully charged.

The only con, and I use that term loosely because of its correlation to battery capacity, is its size. You won't be putting this and your phone in the same pocket but throw it in a bag, purse or backpack and you will not notice it. It's about an inch taller, 1/4 inch wider and about twice as thick as a GS4 with a defender otterbox.

Bottom line, if size is your biggest concern, this isn't for you. It's big and a little heavy but remember, it's a battery. However if extreme capacity and a charge rate that is almost the same as a wall charger sounds good, this is your battery.
