5 Best Power Banks for Backpacking in 2025

Keeping your devices powered on during extended hikes requires the right balance of capacity and weight. These five best portable power bank options deliver reliable performance without weighing down your pack.

Anker Prime 27,650 mAh Power Bank

If your backpacking setup includes more than just a phone—think mirrorless cameras, drones, GPS units, or even a lightweight laptop—the Anker Prime 27,650mAh Power Bank is a power hub worth its weight. With a 250W combined output, it can charge multiple high-draw devices simultaneously and efficiently, meaning less downtime and more time capturing summits or navigating trails.

Where this unit really shines is its smart companion app, which lets you monitor battery levels, temperature, and charging history in real time. That level of insight is a huge plus when you're managing power across multiple days without access to an outlet.

At around 600g, it's on the heavier side, but the tradeoff is peace of mind—and power—on extended trips. It's the kind of gear that turns a stressful “low battery” moment into a non-issue. Rugged, intelligent, and built for serious travelers, this is Anker's heavy-duty answer to the off-grid adventurer.

Anker MagGo Power Bank

For backpackers who don't want to fuss with cables or add bulk, the Anker MagGo Power Bank hits a sweet spot. At just around 200g and barely over half an inch thick, it's ultra-packable and ideal for minimalist setups.

The Qi2-certified 15W wireless charging makes it more than just convenient—it's fast. Snap your iPhone 15 into place and you're at 50% in under 45 minutes, all without digging for cords. That's a huge win when you're low on daylight or hands-deep in camp tasks.

The smart display is another trail-friendly touch. You get real-time updates on battery percentage, output, and estimated recharge time, giving you better control over your power usage—especially important when you're days away from the nearest plug.

With a solid 10,000mAh capacity, it delivers up to 1.8 charges for most phones, making it a compact yet capable pick for shorter treks or ultralight missions.

Anker MagGo Power Bank For Apple Watch

For backpackers deep in the Apple ecosystem, the Anker MagGo Power Bank For Apple Watch is a streamlined way to keep everything topped off without carrying a bag of cables. It's got a 10,000mAh capacity, a built-in USB-C cable, and a certified Apple Watch charger—no adapters, no fuss.

You'll get about two full charges for your iPhone 15 Pro, and up to 11 charges for your Apple Watch Series 9, making it perfect for multi-day hikes or off-grid cabin escapes. The adjustable watch dock is surprisingly secure, and the unit supports simultaneous charging: up to 30W via USB-C and 5W wirelessly for your watch.

What's great for travelers is its compact size—roughly the footprint of a computer mouse—and at 245g, it slips easily into your tech pouch or hip belt pocket. For Apple users who need reliable, multi-device power in the wild, this lightweight power bank keeps your essentials charged without weighing you down.

BioLite Charge 80 PD

The BioLite Charge 80 PD doesn't show off—it just works. With 20,000mAh under the hood, this power bank is ideal for multi-day backpacking trips where recharging isn't an option and you've got more than just a phone to keep alive.

It features a USB-C PD port and two USB-A outputs, letting you power up your phone, headlamp, and GPS all at once without juggling priorities. It's straightforward, reliable, and perfect for gear-heavy hikers who don't want their power bank to be another point of friction.

Weighing 16.4 oz (about 465g), it's not the lightest option—but for the capacity and versatility, it earns its spot in your pack. It's roughly the size of a small paperback and has a durable, trail-tough build that feels like it can take some knocks. The LED battery readout is simple but effective, giving you just enough insight to plan your recharges smartly.

Charmast 26,800 mAh Portable Charger

If your priority is maximum capacity without breaking the bank, the Charmast 26,800mAh is a no-frills workhorse. It’s not flashy, but it delivers serious juice—enough to keep your phone, a tablet, and a couple of smaller gadgets going for days off-grid.

It supports up to 4 simultaneous outputs, including a USB-C port that handles both input and output. For backpackers who carry multiple devices—or like being the person who saves the day at camp—it’s a solid utility piece. You won’t get the absolute fastest charge speeds out there, but the 5.4A total output gets the job done efficiently.

At 14 oz (400g), it’s hefty, but not outrageous for the capacity. The slim profile (just 0.6 inches thick) helps it fit snugly in a hipbelt pouch or side pocket, and the rubberized exterior adds grip and durability for trail life.

What to Look for When Buying a Power Bank for Backpacking

Finding the best portable power bank for backpacking means balancing several key factors. Prioritize what matters most for your trip before making a purchase. Here are factors to consider when browsing power banks.

Capacity and Weight

Capacity is measured in mAh and determines how many charges you can get. Higher capacity means more recharges but adds weight. A 10,000 mAh power bank is a good balance for weekend trips, while 20,000 mAh or more suits multi-day adventures.

Output Ports and Charging Speed

Look for at least a power bank with one USB-C PD port for fast charging modern devices and one USB-A port for older gear. Higher wattage outputs refill phones and tablets more quickly. If you need to charge multiple gadgets simultaneously, choose a bank with two or more outputs.

Durability and Weather Resistance

Backpacking exposes gear to drops, dust, and moisture. Select power banks with rugged housings or an IP rating. Durable designs protect internal electronics and ensure reliable performance in rain or rough handling.

Form Factor and Packability

Slim, compact designs slip into your pack pockets and add minimal bulk. An ergonomic shape makes handling the power bank easier while on the move. Consider the dimensions and weight relative to where you'll store it, hip-belt pouches, jacket pockets, or inside your main compartment.

Extra Features

Pass-through charging lets you recharge the bank and devices at once. Built-in displays or analog indicators show remaining battery. Wireless charging pads offer cable-free top-ups. Some models include flashlights, kickstands, or watch-charging pucks for added convenience.

Conclusion

Selecting the best power bank for backpacking ensures your electronics stay charged without weighing you down. Consider capacity, durability, and charging speed when making your choice. Specialized features like wireless output or watch charging can add convenience. With the right power bank, you'll enjoy uninterrupted connectivity on every trail.

FAQs

What size power bank do I need for backpacking?

Choosing the right size depends on your device usage and trip length. A 10,000 mAh power bank can recharge a smartphone two to three times, making it ideal for weekend hikes. Multi-day trips often benefit from a larger power bank to charge multiple devices and cover longer stretches without access to outlets. Consider weight tradeoffs when selecting capacity for ultralight

How many days can a 20000mAh power bank last?

A 20,000 mAh power bank can power a smartphone about six times over, depending on battery size and charging efficiency. If you average one full recharge per day, a bank could last around five to six days for a single device. Carrying multiple gadgets or using higher-draw devices like cameras will shorten that duration accordingly. Consider also pass-through charging on the power bank.

Is 5000 or 10,000 mAh better?

A 5,000 mAh power bank is lighter and good for emergency top-ups or charging small gadgets once. A 10,000 mAh bank weighs more but doubles capacity, allowing two to three smartphone recharges. For short hikes, a smaller capacity is sufficient, but extended trips or multiple device charging benefit from banks with higher capacity. Balance weight versus charging needs and budget considerations too carefully when choosing between them.

Can I bring a 30000mAh power bank on a plane?

Most airlines restrict carrying power banks with 100Wh or a capacity of 27,000 mAh in carry-on luggage. A 30,000 mAh power bank typically exceeds that limit and may require airline approval or special handling. Always check the carrier's regulations before travel. Packing it in checked baggage is often prohibited.
