This portable power bank is irreplaceable for me, and it has less to do with the capacity

"While the pilgrims of old didn't have smartphones, they are a vital part of doing the Camino in modern times, partly because you need to find and book accommodation (not to mention enter your passport details and the like -- there's a lot of bureaucracy in the modern world), and not to mention that finding shops, cafes and restaurants that are open in the winter season can be tricky."

"The battery in my iPhone 17 Pro Max is vastly better than the one in my iPhone 15 Pro Max was, and lasts significantly longer. In fact, on a normal day, I can start the day with a full charge and still have half left by the evening. But things are different on the trail. There's navigation to consider, as well as a lot of back and forth between the Translate app (which works great for Spanish) and using WhatsApp to communicate with hostel owners"

"Before the trip, I'd kitted myself out with Nitecore's new NB Plus is a 10,000mAh power bank that's built to be rugged and durable, and at the same time cram as much power into as little space as possible - it weighs 5.5 ounces and measures 4.8 x 2.3 x 0.5 inches. That thinness is a real boon, allowing the power bank to be slipped unobtrusively into a pocket or backpack."

I completed the final 75 miles of the Camino Frances from Sarria to the cathedral in Santiago de Compostela in six days. Smartphones are essential for modern Camino logistics: finding and booking accommodation, entering passport details, and locating shops, cafes and restaurants open in winter. The iPhone 17 Pro Max battery performs much better than the iPhone 15 Pro Max on normal days, often retaining half charge by evening. Trail use increases battery drain because of navigation, frequent use of Translate and WhatsApp, and cold northern Spain mornings and evenings in the 30s Fahrenheit. The Nitecore NB Plus is a thin, rugged 10,000mAh power bank that fits unobtrusively in a pocket or backpack.
