The lithium-ion technology from 1993 to the present, is the increase in technology has not been a major breakthrough, even though some small breakthroughs, production up costs are high, the market is not optimistic about the few manufacturers to R & D and production, at present, the battery would like to increase the capacity of the wayvolume, to increase the weight of lithium.
Now portable charger markets in turmoil, such as to select it?
1, the capacity to see: a lot of capacity vacuity 3000mA standard into 5000mA even 6000mA to sell, in fact, to determine whether the mobile power charge vacuity, just have to look like a volume, small size, large capacity mobile power does not exist , is at least the current technology can not be achieved, usually lower than the price of this mobile power, so this shift to support dynamic power should not choose; greater the capacity, the greater the volume, this is for sure.
2, followed by watching 18650 or lithium polymer 18650 liquid inside, if the quality of customs, however, the bigger and more insecure. Lithium polymer lithium mixture is made into any shape, as long as the package is to cross the border is still relatively safe. Therefore, relatively speaking, the election lithium polymer better, especially the large capacity.
3.The electric drive circuit board and materials, this can not be viewed from the surface, the time to buy do not buy too cheap, it is not necessary to buy expensive usb portable mobile charger brand, buy sale protection sent not.
With mobile power to play the game whether it is watching a movie or a business trip, are convenient, but confusion in the market, to buy time to pay more attention to
