When choosing a wireless charging bank, you can consider it from the following aspects:
1. ** Battery capacity ** : Choose the battery capacity that suits your needs. Battery capacity is usually measured in milliampere hours (mAh). In general, the higher the capacity, the more times you can charge the device, but the weight and volume of the power bank can also be larger.
2. ** Output power ** : Check the maximum output power of the wireless charging bank. The higher the power, the faster the charging speed is usually. For mobile phones, the common wireless charging power is 5W, 7.5W, 10W, 15W and so on.
3. ** Compatibility ** : Make sure the wireless charger is compatible with your device. Most modern smartphones support wireless charging, but some older phones or specific brands may not. At the same time, check whether the charging bank supports the Qi standard, because Qi is the most popular wireless charging standard at present.
4. ** Wired charging ** : Some wireless charging banks also provide wired charging function, which can charge multiple devices at the same time. If this feature works for you, choose a power bank with a USB output port and the corresponding cable.
5. ** Size and weight ** : Consider the size and weight of the power bank. If you often carry a power bank, you may want a lighter, more compact option.
6. ** Brand and price ** : Choose a reputable brand and consider your budget. The price does not always reflect the quality, but usually, a power bank that is too low in price may not be of good quality.
7. ** Additional functions ** : Some wireless charging banks have additional functions, such as LED power display, built-in bracket, waterproof and dustproof. Depending on your needs, these additional features may be useful.
8. ** Safety features ** : Check whether the charging bank has safety features such as overcharge protection, overdischarge protection, short circuit protection, etc., to ensure safe use.
