Your needs will differ depending on your adventure style.

Hidden Details Outdoor Adventurers Often Overlook

Outdoor Power Bank Tips & Best Practices
Using your power bank the right way keeps it lasting longer and working better on your trips.

Frequently Asked Questions
Are lithium batteries ok in cold weather?
Extreme cold can permanently harm a lithium battery’s internal components, reducing its efficiency and potentially creating safety risks. Using the battery in freezing conditions may lead to shorter run times and erratic performance. To protect it, store lithium batteries in a warm, stable environment above freezing whenever possible.
How to keep lithium batteries warm in winter?
Specialized battery heaters designed for lithium cells can maintain optimal temperatures even in cold weather. These heaters often have adjustable settings to ensure the battery stays within safe operating limits. Keeping batteries warm this way helps maintain their capacity, efficiency, and overall lifespan.
What is the 80/20 rule for lithium batteries?
The 80/20 guideline suggests charging lithium batteries up to 80% for everyday use to reduce wear. Reserve a full 100% charge for long trips or situations where extended runtime is necessary. Also, avoid letting the battery drop below 20%, as deep discharges can shorten its overall lifespan.
