Power bank which brand is good? How to buy mobile power?

There are now many brands of power bank, power bank which makes good has become our greatest concern, is also a power bank factory are concerned about the problem，how to determine which brand is good power bank? In this case the lack of uniform industry standards, to buy high quality power bank became a headache for consumers. Mobile power which brand is good? How to choose a high quality power bank, comes down from the viewpoint of five areas:

1.technology is strong: the most important mobile power lithium polymer batteries, followed by lithium-ion batteries, now on the market there are many free to open a lithium-ion battery cells for power bank, we can see that it uses batteries must be steel 18650 lithium battery. 18650 refers to a battery having a diameter of 18mm, length of 65mm. 18650 lithium cobalt oxide as the cathode material, single nominal voltage of 3.7V, the charging voltage of 4.2V, 1000mAh lithium battery capacity model above, which is used in laptop batteries.

2.New Look: I believe most people in the choice of a product is a must see for any shape.

3, convenient and practical: Small, lightweight and easy to carry, to achieve power anywhere, this is the most basic attributes of mobile power 5, safe and reliable: whether intelligent power display, automatic identification shutdown load, short circuit, overcharge, over discharge, constant current , constant protection. Ensure the safety of power bank.

 4.efficient use of: battery standard capacity and the actual cell phones and digital devices for charging when not 100%, the conversion rate of power bank play the most important role is to "power bank protection board," so if a mobile power PCB circuit board using good workmanship and design, and use of batteries is relatively good, and has a solid protection circuit, the quality of this mobile power is assured. I think, a qualified power bank conversion efficiency should be at least more than 80%.
