Best Power Bank for International Travel

Especially, a power bank is one of the most crucial devices that should be with you while traveling. But after choosing the wrong power bank might ruin your whole journey, suppose that when you need them and they just don’t work, this doesn’t make any sense. Before choosing the best power bank for international travel there are some couple of things that should be considered.

In this post, we have explained all the critical points that you should keep in mind, before choosing a power bank. If you read the whole article, I hope you will find your best power bank or at least will be aware of the things that are most important.

Ok, but what are the important factors that should be considered before purchasing the best power bank for international travel?


Capacity is the unit that defines how much power can a power bank store. This measured in mAh, the higher the number, the longer you can use the portable charger before it needs to be recharged again.

Typically, smaller power banks have a capacity around 1,000mAh, medium-size comes with 3,000 to 5,000mAh, and the larger units can be of 10,000, 20,000mAh or even more.

But which size is good for me?

Well, this depends on your requirements, if you have an only a smartphone then a 10,000 mAh power bank will be sufficient for you. Because an average smartphone has a battery capacity around 3,000 mAh, and you can charge it three times by that power bank.

And remember, no gadgets are perfect energy efficient, so you can’t expect the 100% result. It means your 10,000mAh battery pack is not going to charge your device as exactly 3.3 times. But you can still get an approximate idea of how many times you can recharge your mobile by comparing the capacity of the power bank and mobile – for example, a 10,000mAh power bank can recharge a mobile twice, that having 4500mAh battery.

But if you have some other device along with a smartphone then you should definitely look for a larger capacity power bank.

Charging Speed

This is another major factor that makes the huge difference between the power banks. Usually, basic models come with 1A, while some advance power banks could deliver 2A or more. The faster the charging rate, the less time you’ll need to spend to charging your device. As the size of your device’s battery increases, choosing a fast charging power bank becomes super important – because you don’t want to wait a whole day to fully charge your device.

Nowadays, most of the mid-range to high range devices are coming with the fast charging features, and all the manufacturers having the different name for that. For example – One Plus uses Dash Charging, OPPO named it VOOC while Motorola uses TurboPower. But it doesn’t matter, if your device supports the fast charging then you should definitely pick a power bank with fast charging.


power bank ports

Most of the power banks come with a full-size USB port, and you can connect an appropriate cable to charge different devices. And, some power banks offer multiple USB ports or USB Type C ports, while some power banks come with a fixed cable of a certain type without any port.

And when we talk about large power banks they even come with AC mains port, that can charge your laptop. You have to pay attention to this area while choosing the power banks.

Other Features

In general, power banks help you to charge your device while you are away from mains power source, but they can do even more than that besides charging. Some portable charger comes with built-in LED to be used as a torch, and other can help you to keep your hand warm in cold climates. Additionally, some power banks offer solar charging, that is even more helpful.

It’s worth reading to all the way to through the description of the power banks to see if it has any useful features.
