Tier: mid. A durable, outdoor-brand 10,000 mAh bank.
The Charge 40 PD is BioLite's 10,000 mAh bank. It's a standard capacity for a weekend or a short section hike, from a brand that builds for camping use.

- Weight: 9.4 oz (265 g)
- Size: 5.9 x 3.2 x 0.7 in
- Ports: one USB-C PD (up to 18 W in and out) and two USB-A. Total output is 18 W.
- Recharge time: about 2.5 hours, per BioLite

How many phone charges?
BioLite's claims vary between listings (from about 1.5 to 3 phone charges). The power and solar buying guide shows the math. With realistic conversion losses, you'll get roughly 1.5 to 2 charges for a typical modern phone.
Compared with others
It's heavier than the slim INIU 10000 and the carbon-fiber Nitecore banks. BioLite says it's drop tested, though the ports are open, not sealed. If you want less weight for short trips, the Charge 20 PD is the smaller sibling.
