how to choose a quality power pack -

The increasing popularity of smart phones has greatly dominated our spare time. However, the development of mobile phone battery technology lags behind and the standby time is too short. therefore, it is essential to equip our phones with the right portable mobile power pack.
Method/step 1.
electric core: at present, there are two kinds of electric cores on the market for mobile power bank packaging, one is polymerization electric core, and the battery is the best electric core on the market, generally, thin mobile power banks use this power supply core, and the price is therefore higher than other mobile power supply groups with the same capacity. The other is 18650 cylindrical electric core, and the Mobile Power Supply Group of the electric core is relatively thick, cheaper than others, the aggregated core has longer life than the 18650 cylindrical core, and the energy conversion rate is higher!2. capacity: the virtual mobile power bank package is not so high in the market itselfBecause the manufacturer deliberately seeks profit, however, just make sure that the mobile power supply group with the same capacity and battery core is usually the same (this is like the bucket and water) 3, other configurations: the mobile power bank is equipped with data lines, and those with better configuration not only have a few different models of data lines, but also a charger to charge the mobile power group!How to distinguish the mobile power battery core available in the market is generally divided into lithium polymer battery core and lithium battery core 18650.
Lithium polymer cores are generally flat in aluminum foil shape and can be recycled for about 1,100 times;The 18650 lithiumelectric core is generally shaped like a No. 5 battery and is recycled about 1100 times.Purchasing ability.For charging a smartphone, select a capacity of 5000 mAh.
It is worth noting that we should not pursue highWhen purchasing mobile power supply, because the larger the capacity, the higher the requirements for the manufacturer\'s technology and product work, the worse the quality of the power bank is prone to some unexpected problems, this brings security risks.Considering the current level of technology, mobile power groups with a capacity of 5000 mA or less are generally safer, and more than 5000 of mainstream power groups may cut corners.How to choose the best voltage.1. input voltage 5 v 1A: fast charging of ipad, iphone, ipod, Galaxy tab, mobile phone, MP3, MP4, PSP, digital camera, GPS navigation system and other products;2.
input voltage 8-12 V: tablet, camera, SLR camera;3. input voltage 12-24 V: laptop.Choose smart, safe and good after-sales servicesale.Intelligence is related to the ability to automatically identify various products being charged and products that choose the best charging scheme;Safety is connected to the smart chip protection board installed in the mobile power supply, which has anti-short circuit, over-charge, over-dischargeSafety measures such as temperature.
Finally, I hope you can get the most affordable but durable mobile power bank
