How to Choose a Backpacking Power Bank

mAh-to Weight Ratio

Capacity is shown as milliamps per hour (mAh) and it’s just a fancy way of describing how much power a portable charger has to charge your devices. The higher the capacity, the more gadgets it can fully charge before the bank itself runs out of juice. 

When backpacking, you always want to consider the mAh-to-weight ratio. As mAh capacity increases, so do size and weight. Find a middle ground between the power you need and the size and weight you’re comfortable lugging around. 

For a one-night trip, aim for at least 5000–9,000mAh like the Anker Powercore 5000 (roughly 1 to 2 smartphone charges). These models are usually small enough to conveniently fit into your pocket.

Look out for how the power capacity, given in mAh, weighs up against the power banks overall weight

If your trip spans multiple days and you need more power, aim for a bank with an mAh capacity of 20,000+, like the Charmsat or the Anker PowerCore+ 26800 PD. Any bigger and you’ll be adding considerable bulk and weight to your pack. 

Charging Speed

For impatient backpackers, you’ll want to choose a bank with a fast charging speed. Battery output is measured in voltage and amperage (here’s an in-depth look at how both work). 

The important thing to remember is that it doesn’t matter how fast your bank charges devices if you don’t match the input and output charging speeds. For instance, if your smartphone has an input of 5V/2A (5 volts and 2 amps), then you need to find a bank with the same output. Otherwise, you won’t be able to charge your devices at full speed. 

Keep in mind that most power banks offer different charging speeds for different port types. 

Number of Outlets

If you’re looking to charge several devices simultaneously, you’ll need a charging device with multiple outlets. 

For many people, one port will be enough. But if you’ve loaded your pack with a number of gadgets and don’t want to take turns charging up your stuff, aim for a bank with more than one port.

The number of charging ports will dictate the number of devices that can charge simultaneously

Just remember, when you charge multiple devices your portable charger might not give maximum current to each port. 

Waterproofing?

If you regularly romp through the backcountry in questionable weather, you might want to double-check the IP rating of any device before purchasing. Power banks all have an IP rating (ingress protection) which describes how much water, dirt, and debris it can safely tolerate.

If you’re looking for a charging bank that can withstand rough weather, aim for a rating of at least IP67 (like our top pick, the Goal Zero Venture 35, or the MyCharge Adventure). 

Added Features

Some other useful features you might want to keep an eye out for are pass-through and wireless charging. 

Pass-through charging means that you can charge a device connected to your battery pack while charging the battery of the bank itself. While this might not be relevant for backpackers who have no means of recharging their power pack, it can be very useful for campground campers. 

Charging station in a campsite
If you have access to a campsite charging station then pass-through charging is a definite bonus!

Wireless charging allows you to skip the cables and charge your devices by laying them on top of the battery. This is an easy way to lighten your pack, although usually, only smartphones are compatible with this technology. 

Best Power Banks for Backpacking: The Verdict

The power struggle is real in the backcountry! If you’re worried about how to keep all your gear powered up during your next backpacking trip, we think no hiker, camper, or outdoor adventurer can go wrong with the Goal Zero Venture 35.
