When it comes to shopping for a portable charger, there are a few important factors to consider. Understanding these factors will help you make an informed decision and find the right portable charger that meets your needs.

One of the first things to consider is the capacity of the power bank. Capacity is measured in milliampere-hours (mAh), but it’s important to note that the actual amount of power you will get out of the power bank depends on various factors such as the cable you use, the device you are charging, and the charging method. For example, Qi wireless charging is generally less efficient than other charging methods. It’s also important to keep in mind that you will never be able to achieve the maximum capacity of the power bank. To help provide an estimate of how many charges you can expect for your devices, many power banks list a rough estimate based on different types of devices.

Charging speeds and standards are another important consideration. The charging rate for devices, such as smartphones, is measured in watts (W). However, most power banks list the voltage (V) and the amperage (A). To calculate the wattage, you can simply multiply the voltage and amperage. Achieving the maximum charging rate also depends on factors such as your device and the charging cable you use. For example, Apple’s iPhones support the Power Delivery (PD) standard, which means you can use higher-power power banks to recharge the device without any issues. Samsung’s Galaxy S range supports a supplementary PD protocol called PPS (Programmable Power Standard) that goes up to 45 W. Additionally, many phones also support Qualcomm’s Quick Charge (QC) standard. It’s worth noting that there are other proprietary fast-charging standards, but you may not find power banks that support them unless they come directly from the smartphone manufacturer.

Pass-through support is another feature worth considering. Pass-through charging allows you to charge your power bank while simultaneously using it to charge another device. It’s important to note that not all portable chargers offer pass-through support. Brands such as Nimble, GoalZero, Biolite, Mophie, Zendure, and Shargeek provide pass-through charging capabilities. However, Anker discontinued pass-through support due to concerns about potential rapid cycling and shortening the power bank’s lifespan. Monoprice does not support pass-through charging either. If you choose to use pass-through charging, it’s important to exercise caution as it can cause the portable charger to heat up.

For those who frequently travel, there are certain restrictions to keep in mind. It is generally safe to travel with a power bank, but there are two important considerations when boarding a flight. First, the power bank must be carried in your carry-on luggage and cannot be checked in. Second, the power bank must not exceed 100 Wh (watt-hours). If your power bank has a larger capacity than 27,000 mAh, it is advisable to check with the airline for any specific regulations or restrictions. However, power banks with capacities below 27,000 mAh should not pose any problems during travel.

In addition to these considerations, there are a few other insights to keep in mind when shopping for a portable charger. It is often recommended to choose a reputable brand that has a proven track record of producing high-quality power banks. Reading customer reviews can also provide valuable insights into the performance and reliability of different portable chargers. It’s also worth considering the size and weight of the portable charger, especially if you plan on carrying it with you on a daily basis. Additionally, look for power banks that offer built-in safety features such as overcharge protection and short circuit protection.

Overall, finding the right portable charger involves considering factors such as capacity, charging speeds and standards, pass-through support, and travel restrictions. By taking these factors into account, you can make an informed decision and find a portable charger that meets your needs. Additionally, it’s always a good idea to choose a trusted brand and read customer reviews to ensure you are purchasing a high-quality and reliable product.
