Charge Fast Portable Charger 40D

BioLite Charge 40 PD — a carry-on-legal power bank that actually keeps up with travel days

The gist: A compact 10,000mAh power bank with fast USB-C charging, sized and rated to survive layovers, hikes, and everything in between.

• 10,000mAh / 37Wh capacity: Enough to recharge a phone roughly 2.5 times before needing a wall outlet, useful on long flights or multi-day treks.
• 18W USB-C Power Delivery: Refills the bank itself in about 2.5 hours, and charges connected devices up to three times faster than a basic 5W charger.
• Charges three devices at once: One USB-C PD port plus two USB-A ports means you can top off a phone, earbuds case, and a travel companion's device simultaneously.
• FAA carry-on compliant: BioLite confirms it's cleared for carry-on luggage, and at 265g it barely registers in a daypack.

BioLite's own spec sheet notes the Charge 40 PD is drop-tested for durability and rated for a -4°F to 104°F operating range, but is explicitly "not waterproof" — worth knowing before packing it for a rainy trek or beach trip.

Best for: travelers who want fast, multi-device charging without exceeding airline power bank limits. Skip it if: you need something waterproof for kayaking or heavy rain exposure. Runs ~$30-45 — check the current price before buying.
