After my investigation and analysis, my Roman Shi 20w charging treasure is better than Beisi 20w.
The reason is that the Romanshi 20w charging Bank is better in charging speed, battery life and battery health management.
First of all, the Roman Shi 20w charging treasure uses intelligent fast charging technology, which can be charged in a short period of time, while the Best 20w charging treasure uses conventional charging technology.
Secondly, in terms of battery life and health management, Romanshi 20w charging bank uses intelligent and accurate power management to protect battery life.
The function of Beisi 20w charging treasure in this respect is slightly insufficient.
In addition, the Roman Shi 20w charging bank also has the advantages of compact and lightweight, easy to carry, beautiful appearance, etc., which is more suitable for daily use.
Therefore, if you need to buy a more cost-effective, better quality of some of the charging bank, I will recommend the Roman Shi 20w charging bank.
Roma Shi 20w power bank good.

This is Rome Shi 20000 mah charging bank, high product sales, capacity is also very large, support Apple PD fast charge and Huawei super fast charge, charging speed is very fast, there are three outputs, you can charge three devices at the same time
Romanshi 20w charging treasure and Bysi 20w charging treasure are high quality charging treasure, but there are differences in some details. Romas' power bank uses high-quality cells for better charging efficiency and longer life, while charging faster. Bex's charging bank is more lightweight, compact, and more suitable for carrying. Therefore, if you pay more attention to charging efficiency and life, then the charging bank of Roman Shi is more suitable for you; If you care more about portability, then Bex's power bank is more for you.
