Best Portable Chargers

A dead phone is more than an inconvenience; it can be a real problem. Whether I’m navigating a new city, trying to board a flight with a digital ticket, or coordinating a meetup on the trail, a portable charger is non-negotiable. I keep one in my backpack, one in my car, and a big one ready for multi-day trips.

But not all power banks are created equal. Some are feather-light for a quick top-up, while others are workhorses that can charge a laptop from zero to full. After testing dozens of models in 2026, I’ve narrowed down the best portable chargers for every situation, from your daily commute to a week off-grid.

 

 

Our Top Picks for 2026

Anker 313 Power Bank (PowerCore 10K)

For just $26, the Anker 313 is the portable charger I recommend to almost everyone. It’s incredibly slim and weighs only 7.5 ounces, so it disappears into a jacket pocket or a small bag. It’s the perfect everyday-carry power bank.

The 10,000mAh capacity is the sweet spot, giving you about two full charges for a modern smartphone like an iPhone 17 or Pixel 10. It has both USB-A and USB-C ports and Anker’s build quality is legendary. It’s a simple, reliable workhorse.

The Downside: It only has two ports, so if you need to charge three devices at once, you’ll need to look elsewhere.

 

 

INIU Portable Charger 10000

At an almost unbelievable price of $20, the INIU 10000 is the best budget option I’ve tested. It doesn’t feel cheap, though. It has a solid build and a handy digital display showing the exact percentage of battery left, which is a feature I usually see on more expensive models.

Its 10,000mAh capacity is plenty for a full day out, but the real trick is its three output ports. You can charge multiple gadgets at once, and the USB-C port works as both an input and an output. It even has a small pop-out phone stand, which is surprisingly useful.

The Downside: You’ll need to bring your own cables, as none are built-in.

 

 

Best for Outdoor Adventures

Nestout 15000mAh Outdoor Battery

The $60 Nestout is my go-to charger for hiking and camping. It’s built like a tank, with a rugged, dustproof, and shock-resistant body that can withstand a 1-meter drop. I’ve had it covered in dirt and tossed in my pack without a second thought.

With a 15,000mAh capacity, it has enough juice for a long weekend. But its best feature is the port selection. You can charge up to five devices at once using its two USB-A ports, single USB-C port, and two other outputs hidden under the cap. It’s perfect for charging a phone, headlamp, and GPS watch all at the same time.

The Downside: At 13 ounces, it’s a bit heavier than your standard city power bank.

 

 

Nitecore NB10000 Gen 4

If every ounce matters, the $84 Nitecore NB10000 is the undisputed champion. It weighs an astonishing 5.3 ounces while still packing a 10,000mAh battery. That gives it the best power-to-weight ratio of any charger I’ve ever tested, making it an ultralight backpacker’s dream.

It’s not just light, it’s tough. The carbon fiber casing helps it resist cold weather, and it has an IPX7 waterproof rating, meaning it can be fully submerged in water. Two USB-C ports handle both input and output, and a clever knock-to-wake feature shows you the battery level without needing to press a button.

The Downside: It’s a premium product with a price to match.

 

 

Goal Zero Flip 24

For just $30, the Goal Zero Flip 24 is all about minimalist portability. This thing is tiny—about the size of a fat candy bar—and weighs only 4.6 ounces. I toss it in my pocket for short hikes or city errands when I just need an emergency boost.

Its 6,700mAh capacity is enough to fully charge most phones once, with a little left over. It has a single flip-out USB-A plug for charging, which is convenient because you don’t need to carry a separate cable for the charger itself. It’s simple, durable, and gets the job done.

The Downside: The capacity is lower than others on this list, and charging is on the slower side.

 

 

Best High-Capacity Chargers

BioLite Charge 100 Max

The BioLite Charge 100 Max costs a hefty $180, but it’s a powerhouse that can do it all. It packs a massive 25,000mAh capacity into a surprisingly compact and carbon-neutral design. This is what I take on long flights or trips where I need to keep a phone, tablet, and headphones running for days.

It’s loaded with features. You get two USB-C PD ports, a USB-A port, and even a 15W wireless charging pad on top. The 65W output means it can charge multiple devices quickly, and it’s even powerful enough to handle some smaller laptops in a pinch.

The Downside: The price is high, making it an investment for serious power users.

 

 

Nimble CHAMP Pro Portable Charger

Priced at $100, the Nimble CHAMP Pro is for people who need serious power and care about sustainability. It’s made from 72.5% post-consumer plastic and comes in plastic-free packaging. But it doesn’t sacrifice performance for its eco-credentials.

The 20,000mAh capacity is great, but the star is the dual USB-C ports with a combined 65W output. I can charge my MacBook Air and my iPhone at full speed simultaneously. It’s also incredibly durable, with a speckled finish that resists scratches and fingerprints.

The Downside: It doesn’t have a wireless charging pad, which you can find on other chargers at this price point.

 

 

Anker Laptop Power Bank 25000mAh

If you’re a remote worker or a digital nomad, the $105 Anker Laptop Power Bank is your best friend. This is a serious piece of hardware designed to power the most demanding devices. Its 25,000mAh capacity is just under the FAA limit for carry-on luggage.

The massive 165W max output is the key feature here. It has three USB-C ports and can easily charge a power-hungry 16-inch MacBook Pro while also juicing up your phone and tablet. I’ve used this to get through an entire workday at a coffee shop without ever looking for a wall outlet.

The Downside: It’s the bulkiest and heaviest charger on this list, so it’s not for casual pocket carry.

 

 

What to Look For in a Portable Charger

When I’m testing power banks, I focus on four things. First is capacity, measured in milliamp-hours (mAh). A 10,000mAh charger is the sweet spot for daily use, giving you about 2 phone charges. For laptops or multi-day trips, you’ll want 20,000mAh or more.

Next is output power, measured in watts (W). A basic 15W charger is fine for a phone, but to fast-charge modern devices or power a laptop, you need at least 30W, and ideally 65W or more from a USB-C Power Delivery (PD) port.

Finally, consider size and weight. An ultralight 5-ounce charger is great for backpacking, but a 1-pound brick that can power your laptop might be better for a business trip. Think about where you’ll be carrying it and choose the right balance of power and portability for you.
