How to select the creditable power bank for your device ?

 As there are various brand power banks in our current market .consumers don't know much about power industry, their buying tends to only look at the capacity and price of the power bank, leading to many dangerous mobile powers entering into market. What brands supply mobile power of best quality? Which brand is a good external battery brand for cell phones? What are the mobile power prices? Here those questions will be analyzed.

Please check the following factors when evaluates a potential power bank  :

1. Select  A high quality mobile power supply should have such functions : over-discharge protection function , over-current protection ,over-charge protection ,short-circuit protection funtions ,generally ,the famous brand will be more creditable than normal brands 
2. Focus on the power conversion rate, and it is enough to choose a product that suits your devices. Don't be greedy for high voltage and low price because usually power banks with low prices but many features will be easy to cause problems, voltage instability or even explosions. Select mobile power capacity according to the device power consumption. In general,usually for 5000-10000mAh  can charge the smart phones for 5 to 6 times, or tablets about 2 or 3 times. It is recommended to select power banks with above 70% conversion rate.
3. Purchase universal type products, because universal mobile power is generally equipped with more than 3 adaptors, applying any charging models. To charge the tablets or laptops, select mobile power supply with current of 2A.
4. Please be alerted on the actual capacity of the power bank ,as there are many power banks in our market marked the fake capacity to attract the client . DeLong Brand promised we never mark the fake capacity on the power bank ..

It depends on what capacity the mobile power is of, and also what mobile power batteries are made of. On the Internet, many people say that 10000mAH to are sold on 7 to 8 dollars. But it is understood that this kind of mobile power batteries are 18650 batteries, and second hand batteries, without security assurance, but false capacity. So their price is low. It is suggested that consumers don't focus too much on prices. Generally good products cost 14 to 70 dollars. It is more important to focus on brand credibility and buyers recommendation of the mobile power to measure which brands are worthy buying.
