Best Power Banks 2025: Never Run Out of Battery When You Need Your Devices Most

There's nothing quite as panic-inducing as watching your phone's battery dip into the red zone when you're miles from an outlet. Whether you're navigating an unfamiliar city, capturing once-in-a-lifetime moments, or closing an important deal, a dead device can derail your entire day. That's where power banks come to the rescue—your portable lifeline that keeps you connected, productive, and stress-free no matter where life takes you.

But here's the thing: not all power banks are created equal. Some are barely bigger than a lipstick tube but pack enough punch for a full phone charge, while others are hefty powerhouses that can keep your laptop running through an entire cross-country flight. The best power bank for you depends on your lifestyle, your devices, and how you actually use them in the real world.

We've tested dozens of portable chargers—from budget-friendly emergency backups to premium fast-charging beasts—to help you find the perfect power companion. Whether you're a frequent flyer who needs laptop-level capacity, a commuter who wants something that slips into a jacket pocket, or a outdoor adventurer seeking rugged reliability, we've got you covered.

What Makes a Great Power Bank in 2025?

The power bank landscape has evolved dramatically. Today's best models aren't just about raw capacity—they're smarter, faster, and more versatile than ever before.

Capacity that matches your needs: Measured in milliamp-hours (mAh), capacity determines how many charges you'll get. A 10,000mAh power bank typically provides 2-3 full smartphone charges, while 20,000mAh+ models can handle tablets and even some laptops.

Fast charging technology: The latest power banks support Power Delivery (PD) and Quick Charge protocols, delivering up to 100W of power. That means charging your iPhone from 0 to 50% in about 30 minutes, or even powering a MacBook Pro at full speed.

Multiple ports for multi-device charging: The best power banks feature USB-C, USB-A, and sometimes even wireless charging pads, letting you juice up your phone, smartwatch, and earbuds simultaneously.

Compact and portable design: Nobody wants to lug around a brick. Modern power banks balance capacity with portability, using high-density batteries to pack more power into sleeker designs.

Safety features: Premium models include overcharge protection, temperature control, and short-circuit prevention to keep your devices (and the power bank itself) safe during charging.

Pass-through charging: This handy feature lets you charge the power bank while it's charging your devices, perfect for overnight charging sessions.

Top Power Banks for Every Need

Best Overall: Anker 737 Power Bank (24,000mAh)

This is the Swiss Army knife of power banks—versatile enough to handle everything from smartphones to laptops with equal finesse. With 140W total output and three ports (two USB-C, one USB-A), it can fast-charge a MacBook Pro, iPhone, and AirPods all at once. The smart digital display shows remaining battery percentage and estimated charging time, taking the guesswork out of power management.

What we love: Charges an iPhone 14 up to 5 times, or a MacBook Pro 13" once. The 140W USB-C port can fully charge a MacBook Pro in under 2 hours. Premium build quality that feels like it'll last for years.

Consider this: At 1.4 pounds, it's definitely not pocket-sized. The investment is significant, but you're getting flagship performance that handles any device you throw at it.

Best for Most People: Anker 325 Power Bank (20,000mAh)

If you want serious capacity without the premium price tag, this is your sweet spot. It strikes the perfect balance between power, portability, and price. With 20,000mAh capacity and dual USB ports, it can charge two devices simultaneously at respectable speeds.

What we love: Provides about 4 full iPhone charges or 2.5 iPad charges. Affordable enough that you won't stress about tossing it in your bag. PowerIQ technology automatically detects and delivers optimal charging speed for each device.

Consider this: Charging speeds aren't as blazing-fast as premium models, but for everyday use, it's more than adequate. The power bank itself takes about 10 hours to fully recharge.

Best Compact: Anker Nano Power Bank (10,000mAh)

This little marvel proves that good things come in small packages. Roughly the size of a credit card and barely thicker than your phone, it delivers 30W of fast charging power through its USB-C port with built-in cable. It's the perfect "just in case" backup that lives in your everyday bag without adding bulk.

What we love: Weighs just 6.9 ounces and fits in your pocket. Built-in USB-C cable means no fumbling for charging cables. Can charge an iPhone 14 twice or bring a dead phone to 50% in about 30 minutes.

Consider this: Single port means one device at a time. The built-in cable is convenient but USB-C only—you'll need an adapter for older devices.

Best for Laptops: RAVPower 27,000mAh PD Pioneer

When your laptop is your livelihood, you need serious power. This beast delivers 90W through its USB-C PD port—enough to charge even power-hungry 15" laptops at full speed. It's TSA-approved for carry-on luggage, making it ideal for digital nomads and business travelers.

What we love: Can fully charge a MacBook Pro 13" or Dell XPS 13 once, plus several smartphone charges. Three ports let you power your laptop, phone, and tablet simultaneously. Includes a 30W wall charger for faster recharging.

Consider this: Weighs 1.1 pounds and takes up significant bag space. The price reflects its laptop-charging capabilities.

Best Budget Pick: INIU 10,000mAh Slim Portable Charger

You don't need to spend a fortune for reliable portable power. This wallet-friendly option delivers the essentials—10,000mAh capacity, dual USB ports, and slim design—without unnecessary bells and whistles. It's perfect as a backup charger or for anyone who charges occasionally rather than daily.

What we love: Costs less than a nice lunch but provides 2-3 full phone charges. The tri-output design (2 USB-A + 1 USB-C) lets you charge three devices at once. LED indicator clearly shows remaining battery.

Consider this: Charging speeds are standard rather than fast. Build quality is solid but not premium-feeling.

Best with Wireless Charging: Baseus 10,000mAh Magnetic Wireless Power Bank

For iPhone 12 and newer users who've embraced MagSafe, this is a game-changer. It magnetically snaps onto the back of your iPhone for cable-free charging while you use your phone. The built-in kickstand transforms it into a viewing stand for hands-free video calls or streaming.

What we love: 15W wireless charging is as fast as wired for compatible iPhones. Strong magnets keep it securely attached even during use. Also includes USB-C port for wired charging when speed matters most.

Consider this: Wireless charging generates more heat and drains the power bank faster than wired. Only works with MagSafe-compatible iPhones (or cases with MagSafe).

Best for Outdoor Adventures: Anker 737 Solar Power Bank (24,000mAh)

When you're off-grid for extended periods, solar charging capability becomes invaluable. This rugged power bank features a built-in solar panel, IP67 waterproofing, and a shockproof design that laughs at whatever nature throws at it.

What we love: Solar panel provides emergency charging when outlets are nowhere to be found. Survives drops, dust, and submersion in water. Built-in flashlight with SOS mode for emergencies.

Consider this: Solar charging is slow—think of it as a backup, not primary charging method. The rugged build adds weight and bulk.

Best Ultra-Compact: Zendure SuperMini 5K (5,000mAh)

When you absolutely need the smallest possible profile, this credit-card-sized power bank disappears into any pocket. Despite its tiny footprint, it delivers 20W fast charging—enough to quickly top up your phone when you're running on empty.

What we love: Weighs just 3.5 ounces—you'll forget it's there. Provides one full charge for most smartphones. Available in multiple colors to match your style.

Consider this: Limited capacity means it's best for emergency top-ups rather than all-day power. Single USB-C port only.

How to Choose the Right Power Bank for You

Match capacity to your daily needs: If you just want peace of mind for occasional low-battery emergencies, 5,000-10,000mAh is plenty. Regular travelers and heavy users should consider 20,000mAh or more. Laptop users need 20,000mAh minimum, preferably higher.

Check your devices' charging requirements: Smartphones typically need 18-30W for fast charging. Tablets want 30-45W. Laptops require 45-100W depending on size. Make sure your power bank can deliver adequate wattage.

Consider portability vs. capacity trade-offs: Bigger capacity means more weight and bulk. Think about how you'll actually carry it—pocket, purse, backpack—and choose accordingly.

Don't forget about recharge time: A 20,000mAh power bank with only a 10W input will take forever to recharge. Look for models with 18W+ input for faster turnaround.

Verify airline compatibility: If you fly frequently, stick with power banks under 100Wh (roughly 27,000mAh at 3.7V) to meet TSA regulations for carry-on luggage.

Power Bank Care Tips for Maximum Lifespan

Your power bank is an investment in staying connected. Here's how to keep it performing at its best:

Avoid extreme temperatures: Don't leave it in a hot car or freezing cold. Extreme temps degrade battery chemistry and reduce capacity over time.

Keep it partially charged when storing: For long-term storage, maintain 40-60% charge. Fully draining or fully charging for extended periods stresses the battery.

Use quality cables: Cheap cables can't handle high-wattage charging and may damage ports or reduce charging speed.

Recharge before it's completely dead: Lithium batteries prefer partial discharge cycles over full drain-and-charge cycles.

Clean the ports regularly: Pocket lint and dust can interfere with connections. A quick blast of compressed air keeps ports clear.

The Bottom Line

In our increasingly mobile world, a reliable power bank isn't just a nice-to-have accessory—it's essential gear that keeps you productive, connected, and stress-free. Whether you're navigating a new city, capturing memories on vacation, or powering through a workday away from your desk, the right power bank ensures your devices are always ready when you need them.

For most people, we recommend the Anker 325 Power Bank (20,000mAh) as the best all-around choice. It offers generous capacity for multiple charges, dual USB ports for flexibility, and a price point that won't make you wince. It's the Goldilocks option—not too big, not too small, just right for everyday carry and occasional travel.

If you need something more compact for daily commutes, grab the Anker Nano Power Bank. Laptop users should invest in the RAVPower 27,000mAh PD Pioneer for its serious charging power. And if you want the absolute best regardless of price, the Anker 737 Power Bank delivers flagship performance that handles any device you own.

Whatever you choose, having a power bank in your bag transforms how you use your devices. No more anxiously watching battery percentages, no more desperately searching for outlets, no more cutting conversations short because your phone's about to die. Just pure freedom to use your devices however, whenever, and wherever you need them.
