How to Choose the Right Power Bank for Backpacking

Not every hike places the same demands on your gear, which is why it's important to consider the following factors when choosing a power bank for your typical trip:

Capacity

The capacity of a power bank is measured in milliampere-hours (mAh) and indicates how much power it can store before needing to be recharged. A 10,000 mAh model is usually enough for day hikes, but longer trips or charging multiple devices often require a higher-capacity option.

Weight and Portability

A power bank should be lightweight and easy to carry, ideally weighing between 400 and 650 grams, which is more comfortable for long walks, especially when you’re already carrying food, water and other outdoor gear. Choosing a size that balances portability helps keep your pack manageable throughout the journey.

Waterproofing and Durability for British Weather

The British weather can change surprisingly quickly, even during summer. While most Camping Power Banks aren't fully waterproof, choosing one with a durable casing and some level of water resistance can help protect it from light rain and accidental bumps inside your rucksack.

Charging Speed and Port Types

Fast charging means you spend less time waiting and more time enjoying the trail. Modern power banks with a USB-C port provide faster charging for compatible phones, tablets and laptops. Multiple output ports are also useful for recharging several devices simultaneously.

Cold-Weather Performance

Low temperatures can temporarily reduce battery efficiency, affecting both your phone and your power bank. So, it's important to choose a power bank with good cold-weather resistance to help maintain stable performance in chilly conditions throughout your hike.

How Many mAh Do You Need for Hiking?

Here are the recommended power bank capacities for different types of hiking trips:

• Day hike (up to 1 day): 5,000–10,000mAh – Enough for one or more phone top-ups depending on your phone battery size and usage.
• Weekend trip (2–3 days): 10,000–20,000mAh – A good choice for keeping your phone, GPS, smartwatch, or camera powered throughout the trip.
• Multi-day trek (4+ days): 20,000mAh or more – Recommended for extended adventures or carrying multiple devices, including tablets or laptops.

Keep in mind that a power bank never delivers its full advertised capacity because some energy is lost during voltage conversion and charging.

To estimate the power bank capacity you need, convert both the power bank and device battery capacities from mAh to Wh. This allows for a more accurate comparison because watt-hours account for voltage. Then apply an efficiency rate to estimate the usable energy.

Usable Wh = mAh ÷ 1,000 × battery voltage × efficiency

For example, use 0.80 for an estimated efficiency of 80%.

Should You Carry One Large Power Bank or Two Smaller Ones?

It depends on the length of your hike and how you prefer to pack your gear. While a single large power bank is simpler to carry and usually offers more total capacity, two smaller models provide greater flexibility as you can share the weight between bags or keep one as a backup.

FAQs

How do hikers charge their mobiles?

Most hikers charge their mobiles using a portable power bank, especially when hiking in areas without access to electricity. Choosing the right battery capacity before your trip helps ensure enough power for navigation, emergency calls, and photos. Fast-charging models with USB-C ports also reduce waiting time during breaks on the trail.

How many days can a 20000mAh power bank last?

A 20,000mAh power bank usually lasts two to three days for most hikers, depending on how often they charge their devices. Phones used for GPS navigation, photography, or mobile data consume more battery, so actual runtime varies. Since some energy is lost during charging, the usable capacity is always lower than the advertised rating.

How to keep your phone charged while hiking?

Start by fully charging both your phone and power bank before leaving home. During the hike, reduce screen brightness, enable Low Power Mode, and switch off Bluetooth or Wi-Fi when they aren't needed. Keeping your phone warm inside your backpack also helps maintain battery performance and extends its operating time.
