Yes, but can not achieve the fast charge function
< br >
Fast charging technology has different branches, the current market is mainly divided into high voltage fast charging and low voltage fast charging two categories.

1. The representatives of high-voltage fast charge mainly include Qualcomm QC and Mediatek PEP, which generally support 9V\/2A or 12V\/2A. Later, there were a lot of vests, such as Samsung FastCharge, Asus mobile phone fast charging, in fact, are Qualcomm QC vests; Meizu's mCharge is Mediatek's PEP vest.

2. The representatives of low-voltage fast charge mainly include OPPO's VOOC, Huawei's SuperCharge and Magic Power. OPPO VOOC and SuperCharge support up to 5V\/5A, while Magic Power supports 5V\/8A. The DASH fast charge technology that OnePlus supports 5V\/4A is actually authorized by OPPO VOOC, which is essentially a VOOC

two The fast charge is related to the charger, the data cable and the internal charging module of the phone. Among them, the charger and the internal charging module of the phone account for the largest proportion, and the data line has a slightly smaller impact, but it is also very important.

Support low voltage fast charging mobile phones due to the high threshold of fast charging equipment, so most need to use original accessories to achieve the ideal fast charging effect, the data line needs to support a maximum of 5A high current, there is almost no third party on the market, and support high voltage fast charging mobile phones, basically can reach 2A current data lines can meet the needs of fast charging. However, the requirements for the charging head are relatively high, such as Qualcomm requirements to support QC fast charge products need to pass certification, with relevant protocols, there will be a different process in the charging process, and VOOC also has a built-in identification IC, only the use of their own fast charge data line
The power bank can be charged using the phone's power adapter. For example, using a charging head with an output of 5V2A to charge the power bank will not have any problems. However, the use of more than 5V voltage to charge the charging treasure will lead to abnormal heating of the built-in chip of the charging treasure, which will have certain security risks. Development information: Charging treasure in the market production is generally the use of ordinary 18650 lithium cell and advanced lithium polymer cell, advanced lithium polymer cell has better security than 18650 lithium cell. In the case of economic permitting, it is recommended to choose advanced lithium polymer battery charging bank.
