November 18, 2025: With this update, our lineup of recommended portable chargers and power banks remains unchanged. The existing picks have been vetted for currency and availability. The Anker Laptop Power Bank has a capacity of 25,000mAh, but more importantly, it can deliver 100W of power from a single port.
Watching your phone or tablet steadily run out of power when you''re nowhere near an outlet is stressful. But there''s an easy solution: a portable battery or power bank. They are available in various sizes and capacities, and can include handy features such as fast charging and multiple ports.
Our testing shows that a power bank can offer your phone between 70-80% of the power it contains, or more depending on the battery. It loses the rest due to the inefficiency of the power transfer. That means a 5,000 mAh battery can fully charge a phone with a 3,500 mAh battery, like an iPhone 16.
Selecting the best power bank for you can not only minimise technological faff on the hills, but can also be the difference between safety and an escalating emergency situation. Steph Wetherell tests the best with additional testing from Peter Macfarlane. Have you ever unexpectedly run low on phone battery while in the mountains?
