How to Choose the Best Power Bank for Backpacking

1) Weight vs. Capacity
For most hikers, 10,000 mAh is the sweet spot (about 2–3 phone charges). Step up to 20,000 mAh for longer routes or camera-heavy kits, but expect a weight penalty.

2) Charging Ports & Speed
Prioritize USB-C Power Delivery (PD) for faster, more efficient charging. If you run multiple devices, look for at least USB-C + USB-A.

3) Durability & Weather Resistance
If your trips involve rain, rivers, or snow, consider an IP-rated model like the Venture 35, or store non-waterproof banks in a dry bag.

4) Brand Reputation & Safety
Stick with brands known for battery safety and quality control. Cheap cells can swell, overheat, or underperform in the cold.

5) Cold-Weather Tips
Lithium cells lose efficiency in low temps. Sleep with your bank in your quilt and keep it off frozen ground.

How Many Charges Will I Get?

A simple rule of thumb:

• 10,000 mAh → ~2–3 phone charges (depending on model and signal)

• 20,000 mAh → ~4–6 charges
  Screen time, GPS usage, and cold temps reduce those numbers.

Final Thoughts

The best power bank for backpacking is the one that fits your trip length, device mix, and weight tolerance. If you’re unsure, start with the Anker PowerCore 10000 PD Redux — it offers the ideal blend of price, performance, and portability for most hikers. Ultralighters should consider the Nitecore NB10000 Gen 2, and anyone heading into rough weather will appreciate the Goal Zero Venture 35.
