The question is, if my mobile phone does not support fast charging, is there any point in buying a mobile power supply that supports fast charging? The answer is yes, even if the mobile phone cannot enjoy fast charging, but shortening the time to fully charge the mobile power supply itself, no Is it also a pleasant experience? What’s more, from now on, mobile phones supporting QC2.0 or MTKPE will continue to appear on the market like mushrooms after a rain. Buying them now can be regarded as an early investment. When purchasing a fast-charging mobile power supply, we only need to pay attention to the following matters. How to choose a fast-charging mobile power supply? 1. Does it support two-way fast-charging mobile power supply? In addition to battery type (18650 and polymer) and capacity, the two most critical parameters are input voltage/current (charging the mobile power supply itself) and Output voltage/current (charge mobile phones). When choosing a fast-charging mobile power supply, be sure to choose a product that supports two-way fast charging, that is, both input and output voltage parameters include 9V or 12V. 2. Choose the most matching charger. In order to save costs, many fast-charging mobile power supplies do not come with a standard charger, so we need to purchase it ourselves. However, when choosing a charger, we must base it on the input voltage/current parameters of the mobile power supply. For example, a mobile power supply supports 9V/2A and 12V/1.5A standard input, but some low-price chargers only support 9V/1.5A or do not support 12V output, which is simply not enough for the mobile power supply. Therefore, qualified users should choose a charger that supports 12V/2A in one step.
