Review: Vinsic 6000 mAh Portable Powerbank

This review represents my personal and unbiased view on Vinsic 6000 mAh Powerbank. In this test I will evaluate everything I think is important for consumer – consumer experience.

What's in the box:

6000 mAh Powerbank;

 micro usb cable.

First impressions: Item arrived in nice – eco package. Powerbank is great looking device. It's made of aluminum alloy, which gives powerbank very high-end feel and protects nicely from fingerprints. It's very compact built and it fits nice in the hand. On the front of the unit, there are power button, 2.1A micro USB output port and 1.5A micro USB input port. On the edge there are four led indicators, that represents battery capacity. Each indicator stands for 25% of the battery power. The dimensions of the powerbank are: 9.3 cm x 5.2 cm x 2.1 cm (L x W x H).

How it works: Powerbank is really easy to use. When you plug device in, powerbank starts charging it automatically. If for some reason doesn't start charging automatically, just press power button once and it will start. When only one indicator is flashing, it means that powerbank has only 5% of battery capacity left and you have to charge it first.

Test:

Battery efficiency: with first fully charged powerbank I charged my Nexus 10 from 54 -100%. Nexus 10 has 9000 mAh battery size. So this means 4140 mAh. Battery efficiency with first full discharge was 69%, which is solid. It takes few battery cycles, before powerbank reach its full potencial of battery efficiency.

Charging time: powerbank was fully charged (0-100%) in 3.5 hours, using desktop charger with 2.1A of output power. This means approximately 1715 mAh per hour.

Charging speed: for charging speed test I charged Note 4 from 37 – 100% in 1h and 20 minutes. Charging speed is approximately 1520 mAh per hour, which is very good charging speed.  

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.

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

Conclusion: I am really satisfied with this powerbank. Powerbank is great designed,great performance and very affordable.  Because of its size you can simply put it in your pocket or bag. I can definetly recommend this powerbank to anyone, who looks for high quality powerbank.

Review: Vinsic Tulip 3200 mAh Powerbank

This review represents my personal and unbiased view on Vinsic Tulip 3200 mAh Powerbank. In this review I will evaluate everything I believe is important for the consumer – consumer experience.

What's in the box:

-          3200 mAh powerbank;

-          Micro USB charging cable;

-          User manual (read it!)

First impressions: Powerbank arrived in nice eco – friendly package. Powerbank itself is high quality made and its design looks really premium (the surface of the powerbank is covered in aluminium). The dimensions of the powerbank  are 9.4 cm x 2.2 cm x 2.2 cm. On the top there is a power button and four indicators. Each indicator represents 25 % of the power capacity (1 indicator flash = 0-25%; 2 indicators flash = 26-50%; 3 indicators flash = 51-75%; 4 indicators flash = 76-100% of the power capacity). On the front side there is one Micro USB input (1A) and one Micro USB output, which power is  also 1A.

How it works: Powerbank is very simple to use. It will start charging automatically, when the device  is connected. If for some reason doesn't start charging automatically, just press power button once. When one led light is flashing it means that battey needs to be recharged.  When powerbanks is fully charged, the led indicators will become solid on.

Test: 

• Battery Efficiency Test : the first thing I always do is to measure battery efficiency ratio. I was able to charge my ipad mini retina from 2 - 35 % (ipad was on airplane mode). After that powerbank ran out of power. Ipad mini retina battery size is 6471 mAh. 33% of 6471 mAh =  2135 mAh. Battey efficiency of this powerbank is 2135/3200mAh = 67%.  
• Charging time: powerbank was fully charged from 0 - 100% in less than 3 hours. 
• Charging speed test: Note 4 was charged from 33 – 84% in 1.5 hours. This means approximately 1100 mAh/ per hour. That is solid charging speed. 
• Compatibility:  Beside ipad mini, I had no problem charging iPhone 5s, Note 4, Nokia Lumia 520, bluetooth Sony headset and HTC Desire X. 
• Overheating YES/NO: I haven't noticed any overheating issues whatsoever. Powerbank gets a little warm when charging, but this is normal.

Conclusion: Overall I am very satisfied with the design and performance of this Vinsic Tulip 3200 mAH powerbank and I recommend it to anyone who is looking for pocketable powerbank. It will fully charge your iPhone (except iPhone 6 plus).
