10/10 — Best in Class

Anker PowerCore 10000 uses high-density lithium cells to achieve 10,000mAh capacity at 6.4 oz — the highest capacity-to-weight ratio in the power bank category. PowerIQ 2.0 charges any USB device at its maximum rated speed.

Who This Is For

Buy this if: Every backpacker who uses a phone for navigation, music, or GPS.

Skip this if: No one — a power bank is required for modern backcountry use.

Pros & Cons

Pros

  • 6.4 oz for 10,000mAh — the best capacity-to-weight commercially available
  • Powers 2.5 smartphone charges from one full charge
  • $22 — most affordable power bank at this capacity

Cons

  • Micro-USB charging input (older standard) vs. USB-C on premium alternatives
  • 10,000mAh is 2 days of navigation use — longer trips need solar supplement

The Detailed Breakdown

Capacity Calculation

Smartphone battery: 4,000mAh. Anker 10000: delivers 6,500mAh to devices (30% conversion loss in any power bank). 6,500 ÷ 4,000 = 1.6 full phone charges. In practice, partial charges and Garmin inReach charging account for the '2.5 charge' marketing claim under mixed use.

Grant's Final Take

The non-negotiable power tool for any trip using electronics. Buy and charge before every trip.
