Bottom line: The NB10000 is 5.3oz for 10,000mAh, which is the best power-to-weight in this category and enough for a phone and a headlamp over a long weekend. The PowerCore 26800 is 14.6oz and carries nearly three times the charge. Under four days: NB10000. Longer, or charging multiple devices: PowerCore.

How many phone charges do I actually get?
Fewer than the raw capacity suggests — conversion losses mean roughly 65-70% of rated capacity reaches your device. A 10,000mAh bank gives about two full charges of a typical phone.
Does cold affect power banks?
Significantly. Lithium-ion capacity drops sharply below freezing. Keep the bank inside your jacket or sleeping bag in winter.
Should I carry solar instead?
Solar suits long trips in open terrain. For under a week, a power bank is lighter, more reliable, and does not depend on weather.
