We've tested all of the best power banks to make sure they are fast, durable, and capable of charging today's phones over and over again.
We test portable batteries for more than just charging speeds. We put them through the ringer to test durability and all features, like the attached USB-C cables that so many new power banks include.

The best power banks in 2025
Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you're buying the best. Find out more about how we test.
Power banks charge at around 80% efficiency. Most premiere flagship phones have a battery around 5,000 mAh, but a 5,000 mAh battery pack cannot charge your phone to 100%, it will be closer to 80% charged.
We've tested these battery packs to see how many times they can charge an average smartphone, and how efficiently they transfer power.
We also compare power banks based on their power-to-weight ratio, which tells us how much battery life you get for the extra weight you're forced to carry. If you want to keep things light, look a higher number, which means you get more power (in mAh) per gram.
Our favorite power bank
The Anker MagGo Power Bank (10K, Slim) is our top pick for a reason: it combines shockingly good performance with a premium, portable design. Its charging capability is its standout feature, proving to be the fastest MagSafe power bank we’ve ever tested, capable of charging an iPhone in under two hours.
This incredible speed is backed by a large 10,000mAh capacity, enough to recharge most phones nearly twice. Plus, its magnetic grip is exceptionally strong, so you never have to worry about your phone slipping or falling off.
It’s not just powerful; it's also "satisfyingly slim." Despite packing such a large battery, it’s remarkably thin, making it a perfect travel-friendly companion. The build quality is fantastic, with a sturdy metal frame and a grippy, liquid silicone charging pad that feels comfortable in hand.
We were also impressed with the high-quality finish, which resists fingerprints and scratches from regular use. To top it all off, it’s made with 75% recycled materials, making it a truly well-built and thoughtful power bank.

The Iniu P50-E1 has earned its place as an everyday carry favorite by perfectly blending pocket-friendly portability with impressive 45W fast-charging power. Our reviewer found it to be genuinely compact and lightweight, easily slipping into a pocket without weighing them down.
Despite its small size, it packs a 10,000mAh capacity. In our testing, this was more than enough for almost two full phone charges, and it proved capable of offering a 55% charge boost to our Steam Deck.
We were especially impressed with its 45W output that supports rapid charging, which allowed us to charge compatible phones like the Samsung Galaxy S25 Ultra super fast.
The P50 delivers better-than-average efficiency, meaning more of the power makes it into your device. Our reviewer loved the "neat solution" of the integrated USB-C lanyard cable, finding it both robust and easy to remove—we even rated it as "fidget-worthy" after testing its durability. The cable can also handle the full 45W speed.
The accurate digital display makes it easy to see the remaining capacity at a glance, and the unit comes with a class-leading 3-year warranty, making this a clear winner for its blend of speed, portability, and value.

The Anker 737 is our go-to power bank for mobile users who also carry high-performance laptops, and our hands-on testing proved it’s a premium device that delivers on its promises. Its standout feature is the massive 140W output, which we confirmed in our tests can sustain rock-steady voltages to charge power-hungry devices like a MacBook Pro at their absolute fastest speeds. \
This power is packed into a large, airline-approved 24,000mAh capacity, making it the perfect power source for long-haul flights.

What truly impressed us in our daily use was the excellent color screen, which our reviewer loved for its real-time charging stats. We found this to be an invaluable tool, not a gimmick, as it clearly displays power output for each port and the overall battery health.

Best cute magnetic power bank
The Ugreen Uno Magnetic Wireless Power Bank 10000mAh 15W distinguishes itself with its whimsical, emoji-based display, though its aesthetic may not appeal to everyone. If you want a MagSafe power bank with a touch of personality, this device is a compelling option. It helps that we've seen frequent discounts from its official list price of $69.99 / £64.99.
In terms of size and weight, the Ugreen Uno strikes a balance, neither overly bulky nor compact. The device features a combination of soft-touch silicone for the MagSafe charging surface and metallic plastic for the casing. An integrated metal stand provides support for the power bank so you can use your phone in Standby mode while it's charging.
The power bank’s most distinctive feature is its smart display, which uses emoji faces to indicate battery levels. These animated expressions can easily be disabled if you're not in the mood.
Charging performance was impressive, and the Ugreen Uno fully charged my iPhone 13 Pro in under two hours, making it one of the fastest MagSafe power banks we've tested. The combination of rapid charging and the unique emoji display makes the Ugreen Uno a worthy contender if you're looking for effective wireless charging that also happens to be cute.

We love this Anker Nano power bank for one big reason: its built-in retractable USB-C cable is an unbelievably practical feature that makes on-the-go charging incredibly convenient. Our reviewer found this to be a massive plus, as the integrated wire is always ready.

This ultimate convenience is packed into a very compact, small-sized charger that our reviewer found can easily slot into a pocket or small bag, making it the perfect companion for anyone who hates carrying a tangle of wires.
The smart design is backed by solid performance. With a 10,000mAh capacity and a 45W maximum power output, it's more than capable of handling phones and other small gadgets.
We also found its handy display was a nice-to-have feature, as it shows power output from the ports and even battery health. Combined with its attractive, grippy finish and a well-designed cord that doubles as a backpack loop, this power bank is a strong value pick packed with talent.

Our reviewer was immediately impressed with its compact form factor, noting it's impressively small considering its 20,000mAh capacity and can easily slide into most pockets.
In our hands-on testing, this 20,000mAh capacity proved to be the real deal, fast-charging our smartphones with ease. Most importantly, you can expect to get 3 or more full charges for a typical smartphone, making it an incredibly reliable travel companion.
What our reviewer found especially very convenient were the handy additional features that set it apart. We loved the integrated USB-C cable that doubles as a carrying loop and the practical built-in flashlight, both of which add to its portability and usefulness.

Best thin power bank
The Baseus Blade Pro is our definitive pick for the best thin power bank because it's the only model we've tested that masterfully combines a skinny form factor with beefy 100W output, perfect for fast-charging phones or keeping our laptops powered.
Our reviewer, who has tested countless power banks, noted it was the only one slim enough for my laptop sleeve, making it an immediate favorite option when traveling light. Despite its incredibly slim 0.8-inch profile, it packs a large 20,000mAh capacity, which our testing confirmed is enough to charge a phone 3-4 times or even bring a typical laptop back to a full charge. We found its four-port layout makes it a versatile hub for all your devices.
Beyond its unique shape, the Blade Pro is packed with features that our reviewer loved. We found its fantastic display to be a standout, as it shows real-time voltage, current, and remaining runtime, so you're never guessing how fast your devices are charging.
It also supports pass-through charging, allowing you to charge the power bank and your laptop at the same time with a single wall adapter. Our comprehensive lab testing confirmed its premium quality, revealing excellent efficiency at various charging rates.

Best compact power bank for phones and laptops
This Anker power bank is our top pick for a compact all-in-one charger because it’s one of the rare models that truly balances portability with serious power. While many 20,000mAh chargers are only suitable for phones, our testing confirmed this Anker portable battery has power output that is the real deal.
It delivers a total of 87W, with a single-port max of 65W, which we found was more than sufficient for charging laptops and other large devices, not just our smartphone. This makes it a "very solid portable and convenient option" for users who need to power more than just their phone.
What our reviewer loved most, however, was its combination of power and unbelievably practical convenience. True to Anker's reputation, it feels solidly constructed" and well-made, equal in durability to the best power banks.
The standout feature is the integrated USB-C cable, which our reviewer found folds away neatly and feels secure. This, plus two extra ports for versatility and a bright and clear display for battery checks, makes it a great choice for on-the-go top-ups for all your gear.

Best compact fast charging power bank
This Xiaomi power bank is a convenient companion for basic travel, and its design is what first caught our reviewer's eye. We were impressed by its smart, minimalist looks and elegant, classy finish. But its main strength is its small form factor, which our reviewer appreciated for taking up little room, noting that not many power banks with this capacity have such a small footprint.
Our reviewer also found the plastic body felt premium and solidly constructed. This sleek design includes an unbelievably practical integrated USB-C cable for added convenience, as well as two extra ports (USB-A and USB-C) that support three-way simultaneous charging.
This small but capable power bank delivers on performance, too. In our hands-on testing, our reviewer found the charging performance is good, and it charged our test phone in just over 90 minutes, which we deemed a solid performance.
More impressively, our tests showed its 10,000mAh capacity goes a long way. After a full charge, the bank had only lost one of its four bright LED indicator dots, leading our reviewer to conclude it will offer 2-3 full charges. For its price, we found this combination of a compact design, integrated cable, and great capacity represents a good value.

The best retro power bank
This power bank is our top pick for its retro design because it injects fun, retro charm into a category full of drab, black bricks. Our reviewer was immediately struck by its eye-catching appearance, which is modeled after a camera from decades ago, right down to the vibrant colorways.
In our hands-on testing, we were delighted to find this design is also incredibly functional. Our reviewer noted the faux camera lens cleverly doubles as an LED display, which we found to be very bright and clear. It’s also pleasingly compact for a 10,000mAh power bank, making it a stylish and accessory that's perfect for travel.
The neat features don't stop at the looks. Our reviewer was pleasantly surprised by the clever cable that comes with the T6S. We tested this cable and found it to be quite versatile, with a smart design that lets you charge using either USB-C or older Apple Lightning ports.
What we loved most was how the durable cable plugs in at both ends to create a secure and convenient carrying loop.

How to choose the best power bank for you
How much power does a power bank really give me?
Our testing shows that a power bank can offer your phone between 70-80% of the power it contains, or more depending on the battery. It loses the rest due to the inefficiency of the power transfer. That means a 5,000 mAh battery can fully charge a phone with a 3,500 mAh battery, like an iPhone 16. If you have a phone with a large 5,000 mAh battery inside, you'll need a power bank that holds at least 7,200 mAh of power to charge your phone fully.
How fast can a power bank charge my phone?
If you want to get the fastest charging speed from a power bank, you need to make sure that it is charging at the same wattage as your phone's USB-C power port. Most phone makers publish their charging speed. Samsung phones charge at 45W. Apple iPhones usually charge around 25W. A Motorola Razr Ultra 2025 can charge up to 68W. If you buy a battery that can charge at the same wattage, you will be able to charge your phone in the fastest possible time.
What's the difference between cheap power banks and name brands?
When it comes to power and electricity, we don't mess around. We want a brand that is well-known and accountable for its products. Cheap batteries can start fires. We only list brands that we know and trust, and we have connected with each of these companies to make sure we know the people behind them. Then we test the products thoroughly in our labs to make sure they stand up to our durability testing and the manufacturer's performance claims.
Are certain power bank brands more reliable than others?
Yes, the brands that we have included are the most reliable brands you will find, and you can buy any of the products these companies make knowing that we have tested them for reliability and durability. Some companies, like Anker, have more advanced charging technology thanks to years of research and development, but all of the brands we recommend make reliable products.
How do I choose the best power bank for me?
If you are charging a small smartphone, a simple power bank will suffice. If you plan on charging a laptop occasionally as well, or many devices at once, you'll want a power bank with more power and more features.
If you have a newer Android phone, or the latest iPhone models, you'll want a power bank with faster charging speeds to get your battery full faster.
You can also find a power bank that charges your phone (or even your Apple Watch) wirelessly. These will usually charge slower, but they can be very convenient if you want to leave wires at home.
Which power bank is the best quality?
Anker makes the best power banks we have tested so far, but batteries from Baseus and Iniu also performed well. All of the power banks on this list passed our testing, traveling with us on the road and powering our devices at home.
Which brand is best for power banks in 2025?
Anker is making some the best power banks right. It offers the best power-to-weight ratio, the fastest charging, and the most useful features. We have also been impressed by power banks from Iniu, which have done very well in our hands-on tests.
How many times can my power bank charge my phone?
A 10,000mAh battery will give your phone around 6,000mAh of extra battery charge. That means a 10,000mAh battery can charge that phone twice ... almost. You may not get to 100% the second charge, but you'll be in the 90% range.
Any power bank that is 5,000mAh or smaller will probably not guarantee 100% charge on an iPhone 16 or larger phone. If you have a big battery phone like the Galaxy S24 Ultra, which packs 5,000mAh inside, you'll need a power bank closer to 8,000mAh or more if you want a full recharge.
How we test the best power banks
We have tested the best power banks by using them to charge a variety of devices, including Apple iPhone, Google Pixel, and Samsung Galaxy phones. We have also charged Apple iPad tablets, and small laptops including a Pixelbook Go and a Surface Laptop Go.
We used the best power banks extensively while traveling to see how well they fit in our luggage and their relative utility versus the weight add to our pack.
Using the Anker Prime power bank, we were also able to test the charging speed claims of other power banks, as the Anker Prime will report charging speed in wattage.
