BioLite Charge 40 PD — the power bank that keeps a remote workday running through an outage
The gist: A compact 10,000mAh USB-C power bank that gives remote workers a real buffer against dead laptops and phones during commutes, coworking days, or power outages.
- 10,000mAh / 37Wh capacity: Enough for roughly 2.5 full phone charges, useful for a long day away from a desk outlet or an unreliable coworking space.
- 18W USB-C Power Delivery: Recharges the bank itself in about 2.5 hours and delivers up to three times faster charging than a standard 5W charger for connected devices.
- Three-device charging: One USB-C PD port and two USB-A ports mean you can keep a phone, earbuds, and a backup device all powered during back-to-back meetings.
- Genuinely portable: At 265g and FAA carry-on compliant, it's light enough to leave permanently in a work bag.
BioLite's product specifications confirm it's drop-tested for durability and rated for a -4°F to 104°F range, but the company is explicit that the unit is "not waterproof" — a fair trade-off for the compact size.
Best for: remote professionals who need reliable backup power for commutes, coworking spaces, or outages. Skip it if: you need a rugged, waterproof brick — this one prioritizes portability instead. Runs ~$30-45 — check the current price before buying.
