It depends on how you usually use it. If you're outdoors a lot, a cell phone case charger is fine, but there are now also mobile power supplies available, and the price is cheaper than a dedicated cell phone case charger. It is not recommended to buy a solar charger, it is absolutely flashy, the charging time is very slow, there is no guarantee that it will continue to charge and it will damage the machine. Also very expensive.
Notes on wireless charging: Do not place anything between the charger and the charger. If a magnetic holder, magnetic protective sleeve or other object is placed between the charger and the charger, the function of the charger may be reduced or a bank card may be placed. If you have such sensitive items in your phone case, remove them before charging. If yours is not charging or charging slowly andIt has a thick phone case, remove the case.

You may hear a slight noise while charging, which is normal.
A few days ago, the United States Patent and Trademark Office published a series of Apple patent applications involving wireless power transmission and unique dispatch systems. The first patent concerns a multiport power adapter that can power multiple electronic devices. The adapter has two methods of wired charging and wireless charging; the second patent relates to a long-distance charging device, which is divided into a long-distance charging device. transmitter and a receiver. It can be charged even when you are far from the charging base. We know that theWireless charging is currently facing many technical problems. First, the charging power is limited, and second, the wireless distance is limited. When you have multiple devices that need to be charged and are participating in simultaneous wireless charging, the power will decrease. The farther away the wireless charging transmitter is at the same distance, the lower the charging power will be.
