Charge Fast Portable Charger 80D

BioLite Charge 80 PD — carry-on-legal power for a full day off the grid

The gist: A 20,000mAh battery pack that's FAA-compliant for carry-on, charges three devices at once, and shrugs off the daily abuse of a travel backpack.

• 20,000mAh capacity with one 18W USB-C Power Delivery port plus two USB-A Quick Charge 3.0 ports — enough for a phone, tablet, and earbuds case simultaneously.
• Fast recharge: the pack itself refills in around 4-5 hours over 18W USB-C, quicker than most power banks at this capacity.
• FAA carry-on compliant, so it's cleared for flights without checking or leaving it behind.
• Rugged matte-finish plastic shell built to handle being tossed in a daypack alongside keys, sand, and gear.

CleverHiker's Bailey Bremner, testing it against other large-capacity banks, found it "recharges faster than any of the other large-capacity power banks we tested" and reported no visible scratches "after extensive use," though flagged it as bulky for anyone trying to travel ultralight.

Best for: travelers who want to charge a phone, tablet, and earbuds through a long flight or an off-grid stay without hunting for outlets. Skip it if: you're packing ultralight — at just over 1lb it's noticeably heavier than smaller 10,000mAh banks. Runs ~$44 — check the current price before buying.
