When you're heading out on a multi-day backpacking trip, a reliable USB-C power bank is just as essential as your tent or water filter. It keeps your phone, camera, GPS, drone—or even your laptop—powered up without worrying about running out of juice off the grid.
Here’s our top pick for 2025—a lightweight yet powerful portable power bank designed specifically for backpackers who demand high performance and convenience.
🔋 Why This Power Bank Is Built for the Trail

Need a quick top-up for your earbuds or smart watch? There's also a 3W wireless charging pad built in, so you can leave the tangle of cables behind.
Weighing about 600g (1.32 lbs), it strikes the perfect balance between power and portability—and it's TSA-compliant, so you can carry it onboard with no issues.

🎒 What to Look for in a Backpacking Power Bank
Finding the right power bank for backpacking means weighing multiple factors—not just battery size. Here's what you need to consider before buying:
Capacity vs. Weight
Measured in mAh (milliamp hours), capacity determines how many full charges you’ll get. The higher the number, the more power you have—but also more weight.
-
10,000mAh: Great for weekend hikes.
-
20,000mAh+: Ideal for multi-day expeditions.
The PB02 hits a sweet spot with 25,000mAh—plenty of juice, still lightweight.
Output Ports & Fast Charging
Look for at least one USB-C PD port (for modern fast-charging) and a USB-A port for legacy devices. If you’re powering several devices at once, make sure the power bank supports multiple high-output ports. The PB02 has 4 total ports and 170W output—more than enough.
Durability & Weather Resistance
Backpacking exposes your gear to drops, dust, and moisture. Choose a rugged, well-built power bank. PB02’s solid casing stands up to trail conditions, and its compact build makes it easy to tuck into your pack or waist pocket.
Size & Packability
A slim, compact profile fits easily in your pack’s side pocket or hip belt pouch. PB02 is roughly the size of a large smartphone and weighs about 600g—portable without sacrificing performance.
Bonus Features
Extras like pass-through charging, LED battery indicators, wireless charging, and even built-in flashlights or watch docks can make a big difference on the trail. PB02’s wireless pad and safety protections make it ultra trail-friendly.
