1. Safety
As our daily digital products, the safety of power bank is the first, and it is also our bottom line requirement. Power bank and hard disk products are the same. Once we choose inferior products, it is likely to bring secondary damage to our digital products. So when we choose the power bank, we must choose the regular manufacturers of big brands, and don't buy three no products for small and cheap. This can effectively improve the safety of the power bank.
2. Determine the scene to use
When we buy power bank, we must consider the scenarios we often use? For example, if we often need to take a plane, then when we choose the power bank, the rated energy must be less than 160wh. If we often work overtime or use it in other places, we must choose a smaller power bank with larger capacity. Because in this way, we can provide more charging for our digital products, which saves the trouble of frequent charging.
3. Whether fast charging is supported.
At present, there are mainly two kinds of fast charging protocols, one is public protocol, the other is private protocol. The common public protocols are PD, PPS and QC. There are still more manufacturers that can support these three modes. But the model private mode refers to the mobile phone manufacturer's own fast charging agreement, in addition to its own supply chain, any other manufacturer has no authority to carry out fast charging, and generally very few of them are open to the outside world. Therefore, for the power bank manufacturers, they generally do not use the fast charging agreement. So when we choose power bank, we must be optimistic about whether it supports private agreement or public agreement. We try to choose power bank with public agreement.
It's not difficult to choose a power bank, but we must choose a suitable one carefully. Only in this way can we bring great convenience to our life.
