First impressions: Item arrived in nice – eco package. Powerbank is great looking device. The surface of the device is made of bamboo, which is really a neat feature.. It's very compact built and it fits nice in the hand. On the front of the unit, there is small LCD, which displays battery percentage. Powerbank is also equipped with 2.1 A micro USB output port and 1.5A micro USB input port. The dimensions of the powerbank are: 9.9 cm x 4.3 cm x 2.5 cm.

How it works: Powerbank is really easy to use. When you plug device in, powerbank starts charging it automatically. When you want to check the battery level, just shake the powerbank. That's really awesome :). 

Test:

a) Battery Efficiency: I always do the battery efficiency test first. In product description it is said, that this powerbank will charge iphone 6 more than two times. This means at least 3620.

I will check that in my efficiency test.

For that test, I charged ipad mini from 76 - 100% and Note 4 from 8 - 81 % (both devices where on airplane mode).

ipad mini battery size = 6471 mAh; 0.24 x 6471 = 1553 mAh

Note 4 battery size = 3220 mAh; 0.73 x 3220 = 2350 mAh 

2350 + 1553 = 3903 mAh

Powerbank's battery size: 6000 mAh

3903 / 6000 mAh = 65%

The battery efficiency of the powerbank is 65%. So yes, it will charge your iphone 6 more than two times. 

FYI: for some reason the powerbank went from 19% to 0% in a second, during third discharge cycle. However that only happened once. I don't know why that happened, but I just want to let you know that.

b) Charging time: powerbank was fully charged (0-100%) in 2 hours and 40 minutes, using desktop charger with 2.1A of output power. This means approximately 2250 mAh, which is super fast. 

c) Charging speed test: for charging speed test I charged Note 4 from 10 – 100% in 2 hours and 30 minutes. Charging speed is approximately 1160 mAh per hour, which is rather slow charging speed.

d) Compatibility: I haven't had any problems charging any device with this  powerbank. Beside already mentioned devices I also charged bluetooth headset, bluetooth speaker, Samsung Galaxy S4, Nokia Lumia 520 and iPhone 5S.

 e) Overheating: I haven't noticed any overheating problems with this powerbank. 

Conclusion: I am quite satisfied with this powerbank. I haven't seen bamboo powerbank before, so I was really happy to review it. It delivers very solid performance, which in my opinion is the most important thing, when we talk about powerbanks.  Because of its size you can simply put it in your pocket or bag. I recommend it to anyone, who is looking for bamboo covered powerbank, with very solid battery efficiency. However, it is pricey.

SCORE: 4.5/5
