Review: RAVPower 3rd Gen Deluxe 15000mAh External Battery Pack

Here is my review of RAVPower 3rd Gen Deluxe 15000mAh external battery pack:

I have received  external battery pack in nice eco - friendly package.

In the box you get:

- battery charger (black or white color)

- 2 USB to micro USB cables

- 2 connectors (mini usb, 30pin)

- travel pouch

- manual
- warranty card

My first impressions were : high quality – compact design, bright led lights indicating battery percentage, matte design, no fingerprints on unit and pretty small for 15000 mAh of power you get. I like the thing, that battery pack has dual usb ports for charging two devices at the same time.  And there is also fully functioning flashlight, which you can turn it on by pressing  button for the 1-2 seconds.  I am also very pleased with all the accessories (usb cables, connectors, pouch) you get in the box.

Out of the box ravpower bank had 3 led lights on (50-75% of battery). I decided to fully charge it first. There are 4 led lights and each one represents 25 percentage of power left in the unit.  I plugged it in, using included micro usb cable and my ipad usb-wall adapter and charged it to 100%.

With first full charged battery pack i charged my ipad mini with retina display, from 0-100 % in airplane mode, my iPhone 5s, from 35-100% and Nexus 10 (airplane mode)from 46-77 % . After that battery pack ran out of power.  I was pretty impressed with its capacity,with awareness that battery pack needs some cycles before it will reach optimal capacaity. Battery pack didn't feel warm for a second. This is great!

Charging ipad mini retina and iphone 5s from battery pack took about the same time as charging from wall charger. But charging nexus 10 with battery pack was about 2x faster than charging from wall charger. 

Charging the battery pack from 0-100 percentage was about 10 hours (with 10W ipad wall charger). It is a lot, but don't forget you get a lot of power in that small-sized unit. When device was charging I noticed one useful feature. When unit is charged over 25 %, one led light stop blinking, the other three led lights continue to blink. The same is when unit is over 50 % and 75% charged (only 2 led lights blinking, only 1 led light blinking, respectively). This feature tells you approximately how much battery is already charged or  how much battery have yet to be charged. When battery pack is fully charged, led lights automatically switch off. Battery pack doesn't overheat during charging, I mean it's not even warm.

After that, i tested charging two tablets at the same time. It works flawlessly as mentioned in the product description.

With battery pack I also charged the following devices: bluetooth speaker RAPOO, Nexus 7 (2012), Sony DR-btn200 wireless headphones,  Garmin GPS watch, ipod shuffle and Samsung Galaxy S4.  Battery pack charged every device I tested.

Conclusion: I am very satisfied with the product and would recommend it to everyone who is looking for a lot of power in small unit size and don't want to spend a fortune on battery pack.  After you buy any of Ravpower products, I recommend to register a product to gain 18 months of warranty protection.
