The reasons that people love backpacking are different for everyone. A backpacking trip is a way to get away from it all and unplug from the modern world, a sort of digital detox. A way to escape from the infectious nature of social media and a healthy way to reconnect with the natural world around us and get some of our attention back to the things that matter most in life.  

Cutting technology out of our lives is a healthy exercise that we all need more of. There is a reason that the new iphone and google pixel have digital well being options that limit the time you spend on certain apps. 

That being said, there are some benefits to having your phone charged on a backpacking trip (believe it or not). The GPS on cell phones work wonders to help you navigate, a picture is a great way to capture a moment (even though they never do it justice), and you can track how far you have gone and how long you have to go. We took a look at the best power bank for backpacking so you can use your phone responsibly while backpacking (emphasize responsibly).

How to choose the right power bank

Besides size and weight, there are other factors to take into consideration when looking for a power bank for backpacking.


The capacity of a charger is the amount of power that it holds and is measured in milliamp hours. Generally, the higher the number the better but with a larger capacity you’ll have to sacrifice size and weight.

For example, the Google Pixel 3 has a 2,915 mAh battery. In theory, a 10,000 mAh battery would charge the pixel 3 times fully and you would still have 1,255 mAh left over. 

It’s important to understand that the mAh of a battery is usually overstated by the manufacturer. You can expect to get about 70% of the stated discharge under normal usage. The best way to test a power bank is to fully charge it and give it a test run with your device, this lets you know how many charges you can reliably count on for your specific device. 

Number of charging ports

The number of ports is how many devices that you can charge at the same time. Most of the larger capacity chargers have multiple charging ports so you can charge a phone and kindle at the same time.

While the option to charge multiple devices is nice, some power banks do slow down as you add more devices to them.

Power output

The power output is how fast (or slow) that the power bank charges your device. The output of power banks range from 1 amp to 2.4 amps. The higher the output amps the faster your device charges. 

2.4 amps power output considered “optimal charging” and this is the highest level of output for most power banks. A 1 amp power output will charge your device, it’s just going to take a long time. 

The larger power banks that have multiple outputs the power output is higher, but it’s also shared. This means that you may not get the same performance in terms of speed while charging multiple devices.

Charging the power bank

Power banks charge at different speeds and the more mAh a power bank holds the longer it takes to charge. Most power banks have transformers inside that adjust accordingly, so you can plug it into any outlet in the world.


The cables that you use to charge your device make a subtle difference in charging speed. Higher quality cables perform better than cheap ones and most power banks will include a cable for charging. Chances are that you already have a cable and the fact that the output is a USB, any cable that you have is going to work just fine. 

Most power banks charge your device with a USB port, you simply plug it in and your good to go. There are power banks that have a hard-wired cord that come attached to the device, however, with the different cable style this is more of a pain in the ass than a benefit. 


Bringing electronics on a backpacking trip is still a new thing. Sure, you might get a few smart ass comments along the way, but when you need to take a quick look at the GPS or capture a memory everyone will thank you later. 

Whether it’s your smartphone, GPS, GoPro, or a kindle having a battery bank is a life saver. Power banks for backpacking are here to stay, so you might as well find the best power bank for backpacking and learn to love it.
