Testing the best portable chargers might sound boring, but I love to figure out which power brick is worth your cash. This is partially because the world of portable chargers is increasingly confusing, filled with vaguely-named products sold by companies you may have never heard of. On top of that, this is the kind of small purchase that can add years of life to your other devices, which is crucial when even the best smartphones released every year don’t always have compelling reasons to upgrade.
Portable chargers have become far more interesting in recent times, going beyond their ports to add built-in cables and screens so you can forget your cords at home and stop guesstimating at how much of your charge is left. That said, I’m still happy to see that the top portable chargers offer USB-C for faster charging and USB-A ports for older cables and devices.
To make sure you’re never low on battery life, I put nearly a dozen of the top battery packs through a series of intensive tests, and I’ve got my eye on the market to see what’s up next from the titans of tech recharging. All of this work has led me to the top three portable chargers, which range from affordable power banks to keep your phone in the green to a powerful brick that will keep your laptop aglow when you can’t find an open wall adapter at the airport.
Iniu Pawsible P41L-E2 Power Bank
Best budget portable chargerThis power bank may have an awkward name, but it more than makes up for that with fast charging speeds and its built-in cable.

Best budget portable charger: Iniu Pawsible P41L-E2 Power Bank
Lesser-known tech accessory brand Iniu makes its name by offering the best affordable portable chargers. The Pawsible P41L-E2 is simply a better version of our previous budget pick, offering a built-in cord and faster charging for only a little more. Its best scores on our in-house testing came when I recharged an Apple iPhone 16 and Samsung Galaxy S25 Ultra from dead, checking how much charge was refueled after 30 minutes.
The Iniu Pawsible P41L-E2 was the only portable charger below $40 to refill over 50% of the iPhone 16’s charge in 30 minutes, and its 70% score on the S25 Ultra even beat a portable charger that costs $100. It also beat our previous budget pick, the simply named Iniu Portable Charger (which is often on sale for less than $20) by posting charging scores between two to three times higher than its cheaper sibling.
In addition to that performance, this portable charger comes with its own built-in USB-C cord, which isn’t included on far-more expensive competitors. That means you won’t have to remember to pack a cable (provided you’re on a modern Android phone or the iPhone 15 or later) for your next night out.
While this portable charger did a serviceable job bringing an iPad Pro M4 back from zero battery life, I saw a surprising hiccup when it could not bring the Samsung Galaxy S10 FE+ back from an empty charge. I will continue to investigate this issue, and plan to update this article with my findings. Oh, and those looking for precision might not like its “paw” LEDs, which give you an estimate of remaining battery life with up to five lights illuminated. Neither of those are a concern at this price, though. Not only did the Iniu power bank thrive in phone recharging, it did so for the same price as a month of 4K Netflix.
Best portable charger for phones: Anker Nano Power Bank
Our best overall portable charger basically takes nearly everything I like about our budget pick and puts it in a better package. The 30W Anker Nano Power Bank posted a terrific score in the iPhone charging test, tying with the Iniu Pawsible P41L-E2. Also, the Nano’s built-in USB-C cord is just better than the one in the Iniu charger, or at least it’s designed to be easier to work with.
That’s all due to the most ingenious touch, a little metal hook that turns the Nano’s cord into a loop that makes it easy to hold while you use the phone. You just snake the connector side of the USB-C cable out from the top side, plug it into your phone, and then hold the power bank aloft by tucking your pinky and/or ring finger into the resultant loop. This way, the Anker Nano isn’t pulling itself down from your port, and you can use your phone while you recharge it. This is crucial for anyone who loves to travel, as you can easily charge and use your phone in one hand to figure out where to go in a maps app while drinking a coffee or holding an umbrella with your spare hand.
The Anker Nano also features a screen that will tell you the exact percentage of remaining battery life and how long it will take to recharge when you’re refueling it. The only real downside about this portable charger is that its 30W charging speed isn’t the fastest you’ll get at this price point. For example, the cheaper Iniu Pawsible P41L-E2 refilled 70% of the S25 Ultra’s battery in 30 minutes, blazing past the 45% score from the Anker Nano.
If you’re trying to decide between the Anker Nano and the Iniu Pawsible, find out if your phone supports 45W charging or not. If it does, and you really want the fastest pocket-friendly portable charger out there, get the Iniu. I’m betting that most people don’t have a 45W-charging phone, and are willing to settle for “really fast” when they can get the portable charger that’s the easiest to use. And that’s why I think the Anker Nano is the best for most people.
Best portable charger for laptops and tablets: UGreen 145W 25000mAh Power Bank
Sometimes simple gets the job done best, as is the case with UGreen’s big brick for charging everything you can throw at it. Not only did it recharge the iPhone 16 and Galaxy S25 Ultra about as fast as any other portable charger (basically tied in the margin of error), but its 145W power meant it posted phenomenal charging scores when I refueled the MacBook Air M4 and Lenovo Yoga Slim 7x. And I’m not exactly shocked: you should be seeing superior charging time when you’re spending more than $70.
Just like the Anker Nano, this UGreen power bank gives you a trio of output options, with dual USB-C ports and one USB-A port. A quick tap of the little button on the side turns on its LCD screen to show you how much juice is left, so you can tell if you need to recharge or not. Oh, and unless you’re frequently refueling laptops, this power bank’s 25000mAh capacity should serve you well for typical use. The other reason I love this brick is that it often gets discounted well below its $100 retail price; as of this writing, Amazon Prime members can get it for $75.
The one thing I don’t love about UGreen’s laptop charger brick is that it’s a bit on the simple side, only offering a low-power “trickle” mode when it’s time to charge smaller devices like wearables. If you’re willing to spend more for some nice extras, then I’d recommend you look at the Anker Laptop Power Bank, which costs $35 more, but throws in two built-in USB-C cords, including a retractable cable and one built into its wrist strap. Oh, and you also get a better display for telling you about its status. Also, when it comes time to refuel UGreen’s brick, you’re going to want to have one of the best USB-C chargers, because refueling it from a USB-A port is going to take far more time than you should spend.
Still, since power outlets can be extremely hard to come by on the go, I recommend everyone check out this UGreen power bank if they frequently find themselves struggling to keep their laptop chugging.
How we tested portable chargers
Design
- Size: Phones are getting big enough these days (some tell me they’re too big), so there’s no need for you to be carrying a portable charger that’s too huge for easy storage. So, I applaud the more compact chargers for understanding that pockets and purses only have so much space. Many of these chargers manage to fit a lot of charge into a small design thanks to their lithium-ion batteries.
- Capacity: Then there’s the other size: each portable charger has its own mAh rating for its maximum internal electrical charge. The bigger the mAh rating, the bigger the battery inside and the more it can recharge. I only tested portable chargers with 5,000 mAh or higher capacities in this round — that’s pretty much the standard entry point, since most popular smartphone batteries are near that amount.
- Ports and cables: While many portable chargers can refuel your phone quickly, their number of ports and cables can be important differentiators. Many chargers come with a cable you can use to plug it into a wall, but a portable charger that features its own built-in cable means you never have to remember to pack one of the best USB-C cables when you’re headed on a trip. Also, some permanently-attached cables are better than others, as some can retract into the case or offer an easier way to hold the charger. And since none of these devices included a wall adapter, we gave extra points to those which included a cable. If you’re curious, we’ve got everything you need to know about how USB-C works.
- Build quality: Does this portable charger feel durable, and able to survive a little damage? Do I feel confident plugging it into my own phone? Without a loud and direct “yes” for both of those questions, a portable charger stands little chance of winning our respect.
- Warranty period: A long manufacturer’s warranty should come with every portable charger, as companies should stand behind the batteries you plug into your phone. Most portable chargers we tested come with at least a two-year warranty.

Performance
- Phones: Since the name of the game is keeping your phone’s battery icon in the green, I tested how efficient these power banks are when it comes to refueling in a short window of time. I tracked how much battery life each gave some of the best smartphones in 30 minutes, after the phones had previously been drained of their charge. This round of testing consisted of recharging the regular iPhone 16 and the fast-charging Galaxy S25 Ultra (which supports speeds of up to 45W). I used the included or built-in cords to charge other devices, as well as each device’s most-powerful port or cable. I also used a Yojock USB-C power meter to confirm the power of each port.
- Laptops: Since the smartphone isn’t the only piece of tech I rely on, I checked to see if any of these portable chargers could recharge two of the best laptops: the 15-inch M4 MacBook Air and the Lenovo Yoga Slim 7x. Unsurprisingly, only our two largest portable chargers proved effective at all, as the rest only resulted in errors such as “Battery is not charging,” and “Slow charger, use a higher-watt charger.” When trying to look for the best portable charger for bigger devices, look for chargers with higher W (watts) specs, starting at around 100W.
- Tablets: In our final round of testing, I checked how our top four portable chargers fared at refueling two of the best tablets from zero. This testing was done with the iPad Pro M4 and the Galaxy Tab S10 FE+.

Other portable chargers we tested
Iniu Portable Charger
This Iniu Portable Charger used to be our budget pick, but its only-slightly more expensive sibling charged our phones more than twice as fast and has a built-in USB-C cord. I understand why many people will still want to get this portable charger due to its low price, but spending a little more here gets you much better results.
Nimble Champ Portable Charger
This little charger packs a decent 10,000 mAh capacity (enough for at least two large phones) and dual fast-charging USB-C ports. Oh, and it’s designed for the eco-conscious among us, with a 90% post-consumer plastic housing and post-consumer scrap paper packaging. It also includes recycling materials for getting rid of your e-waste.

It also includes recycling materials for getting rid of your e-waste.
This tiny portable charger did well in the iPhone 16 charging portion of our test, but it failed to post anything inspiring for the Samsung S25 Ultra, as its 20W charging power wasn’t enough to keep up with other, faster-charging power banks. I admire this power bank for its environmentally-conscious design and packaging, but I have a hard time giving it a strong endorsement. That said, if you put the environment above all else, I say “stay Nimble.”
Anker 25,000mAh Laptop Power Bank
This is the portable charger to buy if money’s no option, and if you don’t mind a larger or heavier power bank. Not only does it offer dual built-in USB-C cables, but one is a retractable cable that basically hides in its body and the other doubles as a wrist-strap. The priciest portable charger on this list provided speedy-fast charging in every round, either tying for the win in nearly every category, and four points shy of the best iPhone 16 charging score. And that’s well within the margin of error. The only real downside on this item, aside from its price, is that its 1.5-year warranty is at least six months less than what the rest include.
Belkin BoostCharge Plus 10K
Simply good-to-OK charging scores in our iPhone 16 and Galaxy S25 Ultra rounds combined with a versatile two-cord design make Belkin BoostCharge Plus 10K a worthy consideration. But when Lightning is on the way out and this charger is $10 more than the Anker Nano, it’s hard to see this as a future-forward pick. It’s also a little larger than some might want.
Anker 22.5W Nano Power Bank
The little sibling to our best pick for top charger, this Anker always feels like the junior. It’s got a lower capacity, less charging power and its design isn’t exactly as convenient. Sure, you can charge while you use your phone, but it’ll leave you with a super-tall handset that’s slightly awkward to use.
Mophie Powerstation Plus 10K
A bit pricey for what it offers, the Mophie Powerstation Plus’ claim to fame in our testing was that it posted the best score for recharging the iPhone 16 from dead, but only by one percentage point. While it gave the Galaxy S25 Ultra 14% more juice than the similar Belkin BoostCharge Plus 10K, it’s hard to argue that this difference is worth an extra $30.
UGreen Nexode Power Bank
Good performance in our testing for charging the iPhone 16 and Galaxy S25 Ultra made this medium-sized portable charger one to consider, especially at $50. There’s nothing quite wrong with it, but there’s nothing super-compelling either, as it offers no built-in cables and a simple set of USB-A and USB-C ports.
OtterBox 3-in-1 Mobile Charging Kit
Slow charging speeds and slightly-awkward adapters meant OtterBox’s portable charger didn’t live up to my own expectations. Also, with microUSB on the way out, its inclusion doesn’t really feel relevant, unless you’re using one of our older picks for the best e-reader.
