Alternatives

• Portable power station— Runs bigger loads at far more weight and cost.

Maintenance notes

• Recharge every few months in storage; lithium self-discharges.
• Don’t leave it in a freezing or baking vehicle long-term.

Buying considerations

• 10,000 mAh covers a phone-heavy weekend; 20,000+ for groups.
• USB-C PD charges laptops and fast phones.
