Buyer’s Guide

If you are going on your next backpacking trip you might want to consider purchasing a power bank. You don’t really want to risk your phone running out of battery and then if something goes wrong there is no way to get in contact with someone to help you.

There are a few things you should consider when buying a power bank. Below we have put together a list of key elements that you need to consider when buying a power bank for backpacking.


Most power banks are quite slim now and therefore quite light. You want something that is easy to carry around. You want to be able to throw it into your bag or a pocket and for it to be quite noticeable.


You need to consider how often you will be using the power bank on your backpacking trip. You’ll also need to consider what devices you will be taking with you and often you expect to be charging them.

It is important to buy a power bank with a large enough battery so that when you do need to charge your phone or ipad, you know that your power bank can handle it.

You don’t want to get into the third day of your backpacking trip and find that you can’t charge your devices again because the battery of the power bank isn’t big enough to make it through the rest of your trip.

Always try to have a larger battery capacity than what you think you will need. You’d rather have some power left than barely making it through the journey.

The capacity of your power bank is important, because you never know when you may need your phone and if you can’t charge it because your power bank doesn’t have enough battery, you could end up in trouble.


It does depend on how many devices you intend to take with you and will need to be charged. For a lot of people, one port is enough as they only use it for their phone. While if you bring multiple devices then two or more ports may be needed.

The number of ports a power bank has can be a good and bad thing. You could take turns to charge devices, if your power bank only has one port, but sometimes it is easiest to charge multiple things at once.

It is up to you, but sometimes 2 ports is better than 1, especially if you need two devices charged quickly.

Input And Out Charging Speeds

The faster you want your devices or the power bank to charge, then results in a faster battery pack input and output rates. It would be ideal to have a quick charging power bank, so then there is less waiting round for devices to charge.

Makes of phones all take different amounts of time to charge, as do different makes of power banks. What you want is something that can charge at a reasonable length.

The power bank is known for taking a while to charge, but ideally you would want to be able to charge it overnight, so then it is ready to take with you during the day.

It is important to look into the input and output charging times, because not everyone wants to wait hours for their phone to charge and not everyone can wait 10+ hours for their power bank to charge. You need to find charging speeds that are reasonable for you.


We have given you a list of the best power banks that you can use on your next backpacking trip. You want something that is durable and will be able to keep you connected to the world, in case something goes wrong.

You want to be able to rely upon your power bank to charge your devices as quickly as possible. All of the power banks we have mentioned above, will get you through your next backpacking trip easily.

Overall, the best power back for backpacking and hiking on the market in 2021 is the Anker PowerCore III Elite 25600.
