Be it a business trip or a leisure trip, you would always want your smartphones, tablets or laptops to remain charged up. Since you would spend most of the time-traveling, you need to have a portable source of power that can charge up your devices. This is what exactly a power bank does. Carrying a charged power bank along ensures that your smartphone or iPad never runs out of battery power. You must choose the best power bank as per your requirement.

Here are some points that will help you choose the best power bank for your devices.

• Weight and size

A mobile power bank is meant to be a portable device. Therefore, you need to choose the right size and weight that will fit in your pocket, purse or bag, along with your smartphone and is light enough.

• Capacity

The power that a power bank gives out is measured in terms of milliamp-hours (mAh). The capacity of the mobile devices that the power bank recharges also measured in terms of mAh. This is the most important factor that determines the quality of the power bank. Basically, it determines how much charge the power bank can carry. Generally, the capacity of a power bank ranges from 2,000mAh to 20,000mAh. In some cases, it also ranges up to 40,000mAh. To calculate the number of times the power bank can charge a device can be measured by dividing the capacity of the power bank by the capacity of the battery of the device to be charged.



A 20,000mAh power bank can charge a Samsung Galaxy S8 approximately 4.5 times, an iPhone 7 up to 6 times and an iPad mini 4 times.
It would be wrong to say that the best portable power bank is the one with the highest capacity. That is because capacity impacts the size and weight of the power bank. You also need to keep in mind the size and weight while you look for the perfect capacity. Higher the capacity of the power bank, the bigger will be its weight and size. Therefore, it will be difficult to carry them around. The Imazing IM10 power banks offer the best ration of size and capacity (10,000mAh). It is the perfect size to carry around throughout the day and it stores enough power to charge your mobile devices a couple of times a day. It is considered to be the best power bank for iPhone.

• Inputs

Your power bank needs to be charged too. A good power bank for iPhone should be able to charge itself real quick. The charging speed also depends on the kind of wall charger you use to charge the power bank. The latest power banks offer an output of 2.4A. A wall charger with an output power of 2A is also a good option. However, it would only work with a power bank that has 2A input. A wall charger with 1A output would take a longer time to recharge your power bank.



• USB Charging

The USB charging is the most basic feature which is present in most of the power banks. The advantage of having a USB charging feature is that it can be used for charging various devices at the same time.
