There are a few things to think about when you’re shopping for a portable charger.
capacity: Power bank capacity is measured in milliampere-hours (mAh), but this can be a bit misleading as the amount of power you get depends on it. The cable you useThe device you are charging, and the charging method (Qi wireless charging is less efficient). You will never achieve maximum potential. We try to provide an estimate of what you will get in terms of costs for the devices.
Charging speed and standards: Charging rates for devices like smartphones are measured in watts (W), but most power banks list voltage (V) and amperage (A). Thankfully, you can calculate wattage yourself by multiplying voltage and amperage. Unfortunately, achieving that maximum rate also depends on your device, the standards it supports, and the charging cable you use. Many smartphones, incl Apple’s iPhoneSupport power delivery standards, meaning you can use high-power power banks to recharge the device without any problems. Some phones, such as Samsung’s Galaxy S range, support an additional PD protocol called PPS (Programmable Power Supply) that goes up to 45 W. Many phones also support Qualcomm’s proprietary Quick Charge (QC) standard. There are also other proprietary fast-charging standards, but you won’t usually find power banks that support them unless they come from a smartphone manufacturer.
pass by: If you want to charge your power bank and use it to charge another device at the same time, it will need pass-through support. Nimble, GoalZero, BioLite, Mophie, Xandur, and Charge portable chargers support pass-through charging. Anker discontinued support for pass-through in some of its products because it found that the difference between the output of the wall charger and the input of the device charging could cause the power bank to turn on and off quickly and shorten its lifespan. . Monoprice does not support pass-through charging. We would advise caution when using pass-through, as it can also cause portable chargers to heat up.
travel: Traveling with a power bank is safe, but there are two restrictions to keep in mind when you board a flight: You must have a portable charger in your carry-on luggage (it cannot be checked), and it Should not exceed 100. Wh (watt-hours). If your power bank has a capacity of more than 27,000 mAh, you should check with the airline. Below that there should be no problem.
