The choose and buy of charging treasure method

Source: 2020 - 03 - 25 clicks: therefore purchase charger experience ability emergency choose 5000 ma advice for short periods of time, travel choice 10000 ma, generally higher than 15000 milliampere or below 3000 milliampere mobile power, practicality is greatly reduced. Batteries at present, mobile power supply mainly adopts liquid lithium ion battery and lithium polymer batteries, the output efficiency is relatively stable. Compared with the liquid lithium ion battery, lithium polymer battery has the characteristics of light weight, safe and efficient. Conversion rate if the conversion rate is too low, mobile power supply circuit loss will be very big, may have a fever or even explode. Conversion rate at about 85% of products have very good, claims that the conversion rate in more than 90% May be wrong. Compatibility of the product is a variety of digital products, and interface circuit design it is almost the same, before buying must first determine their own electronic products need interface, the information such as voltage, if you can try to come to the counter. Attachment and add function if there are multiple charging adapter to extend the use range, dual port can recharge two electronic products at the same time, you can use the emergency LED lamp.

It is important to note that now top-up treasure price difference is very big. In general, it will be for the battery type, brand, varies according to design, function, etc. To measure the pros and cons of a mobile power supply, from charging performance, durability, security, conversion efficiency, appearance and so on comprehensive consideration, the price is just one of the reference standard, can't decide the quality completely.
