Best Power Bank for iPhone for 2023

Take your charger on the go. Here are the best portable chargers for iPhone tested and reviewed by CNET experts.

If you need power but don’t have access to an outlet, It’s obviously good to have a portable charger on hand. And while new phones like the iPhone 14 feature decent battery life, you still might not make it through the day, especially if you use your phone for gaming, video shoots and navigation, all of which which tend to take a toll on battery life. That’s why having a portable charger is a must, especially as weighty battery cases have essentially been phased out and are no longer an option.

The best portable power banks and battery chargers come in all shapes and sizes. The more affordable options tend to require use of a cable for charging, but we’re seeing more and more magnetic wireless chargers that stick to the back of your MagSafe-enabled iPhone or MagSafe-enabled case. I personally like portable power banks for iPhones that have an integrated Lightning cable, which offers fast charging. 

While this list is geared toward iPhones, any portable battery pack on the list with a USB-C or USB-A out ports will work perfectly well for charging an Android smartphone (or any other portable gadget), so long as you provide a compatible smartphone cable.

So what’s the best portable charger for juicing up your iPhone on the go? Here are out top picks, all of which I’ve tested and reviewed. I’ll update this list as other top portable chargers hit the market.

Infinity Lab is Samsung-owned Harman Kardon’s new accessories subsidiary, and I like its InstantGo 5000 and InstantGo 10000 power banks, which come with an integrated Lightning cable for easy charging of iPhones. The larger 10,000 mAh costs $20 more and is heavier and bulkier, but it can charge most iPhones twice.

While i can’t say how well this portable battery from iWalk will hold up over time, it’s a good power bank for the money, if it does manage to hold up. Along with an integrated Lightning cable that tucks away into a slot when not in use, it’s got an integrated 9,600-mAh battery, which should charge most iPhones almost twice. There’s also an LED in the battery that lets you now how much juice its got left. 

The battery is a little bulky but it’s not huge for a 9,600-mAh battery. There’s nothing too fancy about it — it does feel a little generic — but it’s also about half the price of most portable batteries with a built-in Lightning cable. The Lighting cable will fast charge your iPhone at 18 watts and there’s also a USB-C out port for charging a second device (or a device that doesn’t charge via Lightning).

Zagg hasn’t promoted its Mophie Powerstation Plus With PD charger much, but it’s one of the best portable batteries with an integrated Lightning cable. It houses a 6,000-mAh battery (that’s enough to fully charge even larger iPhones) and the Lightning cable offers 18W fast charging and tucks into a storage slot when not in use (a flap covers the storage slot so you may not realize there is a built-in cable at first).

You charge the power bank with a Lightning cable, and there’s also a USB-A out port for charging a second device (or a device that isn’t an iPhone). The battery is available in a few color options, but I’ve mainly seen it in black and gray.

MyCharge’s Hub portable chargers come in a few different sizes and not only have an integrated foldable wall plug but integrated Lightning and USB-C cables, so you can charge both Apple and Android devices. It’s a little bulky, but with a 4,400-mAh battery, it should be able almost fully charge your smartphone, depending on its size. The step-up 6,700-mAh model is about $20 more.

Anker

Thanks to Gallium Nitride (GaN) technology, chargers have been getting more powerful while shrinking at the same time. The latest example of that trend is Anker’s new line of GaNPrime chargers with next-generation GaN 3 technology, which the company says is even more energy-efficient. The Anker Power Bank 733, combines a 65-watt charger with a 10,000K-mAh portable battery and is part of the new GaNPrime line. It’s pretty compact for what it is and offers two fast-charging USB-C ports and one fast-charging USB-A port. You can charge up to three devices at once, but note that to get a full 65W charge for a laptop, you can only plug in the laptop.

Best MagSafe-compatible magnetic battery packs for MagSafe-enabled iPhones

David Carnoy/CNET

What’s cool about Anker’s 622 magnetic battery is that it’s a wireless battery that has an integrated magnetic flap that converts into a stand. You won’t get fast wireless charging from this 5,000-mAh battery (it charges at up to 7.5 watts), but it’s slim and easy to carry around. 

It charges via USB-C, and if you use a USB-C to Lightning to charge your iPhone, it will charge at a faster rate of 12 watts. That’s not as fast as what a 20-watt USB-C power adapter can deliver, but it’s faster than 7.5 watts.

It’s listed for $60 at Amazon, but you can save $10 by activating the instant coupon located on the product page.

If you’re looking for a bigger portable battery that charges your phone wirelessly, the Baseus Magnetic Wireless Power Bank is an excellent option. It houses a 10,000-mAh battery that can charge an iPhone 14 around two times — but it’s still somewhat compact. 

The magnet is strong, and I also liked that it has an integrated flip-out kickstand, so it converts into a stand. There’s also an LED battery life indicator on back of the battery that tells you exactly how much juice the battery has left (you see the actual percentage). The Baseus Magnetic Wireless Power Bank is available in three color options with the black version currently costing a few bucks less.

You don’t want your phone to go dead on the mountain, so it’s always good to pack a battery pack.

MyCharge calls its new line of magnetic power banks Superhero MagLock, implying that they’re real saviors. I was impressed by their design. Not only do the batteries, which come in various capacities, have strong magnets and stick really well to the back of your iPhone 12 or 13, but they have raised coils, which are supposed to help reduce heat levels while charging. It does seem to work.

The 3,000-mAh battery is lightweight and slim and is nice to have around for some emergency charging. However, it won’t get you a full charge, so you’ll probably want to step up to one of the higher-capacity options like the 6,000-mAh model. The 9,000-mAh version is beefy and feels like your phone is attached to a small brick — the battery and phone do fit in your hand nicely, but the combo certainly isn’t pocket-friendly.

All the MagLock batteries charge Qi-enabled iPhones at 5 watts, although you can get faster charging if you go wired and use a USB-C-to-Lightning cable. I also liked how there’s a chime when the charging starts and your phone tells you how much juice is left in the battery pack (it’s tied into iOS 15). You can wirelessly charge Android devices as well but the MagLock won’t stick unless you have a metal ring on the back of your phone’s case (stick-on rings are available).

The SuperHero MagLock is available in a few colors and has a glossy finish. It’s currently the best designed magnetic power bank — better even than Apple’s.

Like some competing magnetic wireless chargers, Mophie’s magnetic power bank isn’t an official Apple MagSafe accessory, but it magnetically adheres to the back of your MagSafe-enabled iPhone or MagSafe case — yes, it sticks nicely — and is svelte for a 5,000-mAh battery. It can also be used with other phones that support wireless charging and comes with a stick-on magnet. 

For wireless charging, Mophie says you’re looking at up to 7.5 watts for iPhones, but it felt a little more sluggish to me (more like 5 watts). If you need a faster charge, you can connect a USB-C-to-Lightning cable to bump the speed up to 12 watts.

Mophie’s Powerstation Wireless Stand with MagSafe is currently only sold through Zagg (Mophie’s parent company) and Apple. It’s not cheap but is a versatile 10,000-mAh battery battery with both a stand and MagSafe charger built in, and also has a threaded tripod mount at the bottom. 

Since this is an official MagSafe charger, the battery does charge at 15 watts, making this among the fastest wireless external battery chargers out there and will also charge the AirPods 3 and AirPods Pro models with MagSafe. If you use a USB-C-to-Lighting cable (not included) with it, you can charge at 20-watt speeds. You can also charge two devices at the same time.

Note that first-time buyers at Zagg can get a 20% off discount by supplying their email address. 

Best battery packs for iPhones with fast charging USB-C out

Mophie

If you’re looking for a compact external battery pack for your iPhone (or any smartphone), Mophie’s pocketable Power Station Mini (2022) features a 5,000-mAh internal battery and 20-watt USB-C PD fast charging. (You’ll need a USB-C to Lightning cable to take advantage of that fast charging if you’re an iPhone owner.) That battery will allow you to fully charge your iPhone.

For $20 more, you can pick up the 10,000-mAh version with dual USB-C ports — both come in black or blue colors. Also, note that Zagg, Mophie’s parent company, offers a 20% discount off your first purchase, so that model (it’s simply called the Power Station) is actually $50.

The Anker 523 PowerCore Slim 10K PD is impressively slim for a 10,000-mAh portable phone charger and has a fast 20-watt USB-C out charging port (it’s also a USB-C input to charge its battery), plus a 12-watt USB-A out port.  While the Anker 313 PowerCore Slim 10K is cheaper, this offers fast USB-C out charging, which makes spending the extra dough a big plus if you have a USB-C to Lightning cable.

Nimble’s Champ portable charger uses recycled plastic in its construction. You have to pay a bit more for going green, but it is a nice, compact 10,000-mAh charger that features PD 4.0 fast-charging (18 watts) via its single USB-C port. Also, the coupon CNET25 will get you 25% off at checkout. 

Nimble also sells some higher-capacity fast-charging battery packs. 

Best battery packs that convert into wireless charging stands

Otterbox

Otterbox gears its Folding Wireless Power Bank (10,000 mAh) toward those who like to watch movies on their phones or play games with a controller. It has a built-in stand that folds down when you take it on the go. It also has USB-C and USB-A ports that are capable of fast-charging your phone at up to 18 watts. The wireless charging is up to 7.5 watts with the iPhone and 10 watts for Android devices. 

What to look for

Here are a few things to keep in mind when shopping for an external battery pack or power bank:

  • A higher power output rating (mAh, short for milliamp hours) means more charges — but also a heavier portable charger weight. 
  • For the latest iPhones (everything after the iPhone 7) you should buy a battery with at least a 3,000-mAh capacity, which should give you at least one full charge for a device. With the exception of the Atom XS, all of the models featured above hit that mark. 
  • Multiple integrated charge cables or USB-out ports will allow you to charge more than one device at a time, such as an iPad or another iPhone.
  • These best portable chargers for iPhone all use lithium-ion rechargeable batteries, and should thus always be stored in carry-on luggage when flying. Airlines and regulatory agencies are increasingly banning li-ion batteries in checked baggage.
  • If you want maximum power output, opt for chargers with USB-C PD (power delivery) models, which should charge nearly every device smaller than a laptop, such as a tablet or Nintendo Switch.

I Played the 5 New Overwatch Heroes Dropping Next Week. Here Are My Thoughts

The five new heroes offer a variety of playstyles that should appeal to a range of players across all three roles.

At Blizzard’s campus in Irvine, California, a week before Wednesday’s Overwatch Spotlight showcase, I sat down with other journalists from across the globe in a room packed with PCs to play the five new Overwatch heroes early. Well… to play most of them, as I tragically ran out of time before I got to play as Jetpack Cat in a full match. But I did get a feel for her in the practice range. 

A few caveats: I only played a single game or round as each of the other four playable characters, splitting a competitive Gibraltar game between the two new damage heroes. That’s not nearly enough time to fully understand the intricacies of their kits. And each of the games I played pitted the five new heroes against those same five heroes, so my observations about strengths and matchups are limited to a very particular team composition. 

Still, it was enough time for a few key takeaways. I’ve broken down my experience and initial analysis of each hero below. 

Jetpack Cat will appeal to creative players and people who enjoy ‘pure support’ gameplay

Jetpack Cat is real, and she’s the headliner among the newly released heroes. Although I didn’t get to take the jetpack for a spin in an actual match, her kit felt intuitive while also allowing plenty of room for creativity. Her primary fire shoots Biotic Pawjectiles that seemed to pump out notable damage and healing. 

Her kit-defining Lifeline ability drops a line that allies can interact with, allowing you to fly them around the map, offering lots of creative possibilities. Allies have to opt into the lift: «We’d rather this be a collaborative thing,» said Game Designer Scott Kennedy, referencing frustrations with Life Weaver’s ability to forcibly move teammates. 

But if your first question, like mine, was, «What about BOB?» Dawson confirmed that you can fly Ashe’s omnic butler around at your whim. (I like to imagine that BOB has a choice in the matter, he just always opts in.) Jetpack Cat’s regular abilities are a resource-limited boost ability and a purr that heals allies and knocks back enemies immediately around her.

As for the ultimate… look, you’re going to get memed on. You need to understand and accept that now. It’s OK. It already happened to me.

Activating your ultimate pulls out a laser pointer, and confirming with primary fire sends Jetpack Cat careening toward the laser and picking up the nearest enemy. It took playtesters approximately zero seconds to realize that you could boost forward before the ultimate, giving people almost no time to react before they get dragged away to their doom.

I do think Jetpack Cat has meaningful offensive capabilities, especially up close, where she can minimize the travel time of her projectiles or just boop people off the map with her purr. But her kit also feels like it will attract the type of player who just wants to pump healing into their team without handling the responsibility of being an aggressive threat. Her primary fire and purr ability can quickly burst-heal a tank from low health, and the combination of permanent flight with a meaningful speed boost allows the hero to heal teammates without having to directly confront enemies. 

Domina lets tank players lock down important angles and put out serious firepower

Domina was designed as a poke tank, competing with Sigma in compositions that aim to put out a lot of ranged damage from different angles and shoot down teams before they ever get close. She can do that with a beam weapon that has impressive range and deals extra damage on the last tick of each shot.  

She has a curved barrier she can deploy at range, allowing her to cut off fire from a particular angle or shield the enemy tank from healing. But her shield is curved, with square panels that can be destroyed individually. She can also push enemies back and stun them, or fire an explosive crystal that she detonates manually. Her ultimate ability sends out a wide projectile — any enemies hit by it are trapped in a barrier and take massive damage if they don’t break out before a brief delay. 

In the media playtest, a well-supported Domina was a menace. Her passive ability restores her shield health, and one of her perks activates passive healing when she deploys her barrier, which combine for meaningful survivability as long as she can keep her distance. Her boop ability stuns heroes who hit a wall, making her hard to chase down individually, and her primary fire felt very threatening, especially when landing headshots with its final burst of damage.

If you like Sigma’s general gameplay but not his double-projectile weapon, or if you prefer more proactive abilities, Domina might appeal to you. I think her more offensively tuned abilities will make her a little more vulnerable to being overwhelmed up close than Sigma, but also more reliable against flying or speedy enemies. She’ll also be fun if you enjoy the fantasy of Overwatch’s hardlight technology or just playing a swankier-than-thou villain. 

Mizuki rewards high-skill support players who want to be in the fray

Mizuki was the most complex hero I tried in the playtest. He heals an area around him, similar to Brigitte, but the amount he heals increases as he puts out more damage and healing. He was designed to be a support hero that allows or even forces you to play in different, more vulnerable spaces than other supports, who tend to prefer a little separation from the team, Associate Game Director Alec Dawson said in a group interview ahead of the Spotlight.

Mizuki’s primary weapon doesn’t heal allies, but it can critically hit enemies and bounce off surfaces. His alternate fire causes him to toss his hat, which ricochets among a few allies to heal them and Mizuki as it returns. His Binding Chain ability fires off a chain that briefly hinders the enemy. His Katashiro Return ability drops a small paper doll while giving Mizuki a small dash and increased movement speed, and he can reactivate the ability to return to the doll’s location. It’s a neat tool that can be used to play mind games with your enemies or just quickly retreat to safety. 

His ultimate, Kekkai Sanctuary, creates a cylindrical area to heal allies and absorb enemy projectiles. It’s not a huge burst of healing, and any weapons shot from inside the sanctuary don’t get absorbed, so it isn’t a «things in this circle can’t die» ultimate. But it is a powerful piece of protection against long-ranged threats and was effective against Emre’s ultimate in the playtest. 

Mizuki felt like the kind of hero that scales aggressively with familiarity and skill, meaning a bad Mizuki might be close to useless, and a good Mizuki will be a terror. Landing hinders and keeping up a high healing multiplier will be important, as will be timely hat tosses. His relatively low healing throughput but decent utility feels particularly threatening when supporting a damage hero on an angle — landing a hinder and extra damage will help secure kills, while his hat toss and passive healing will help them hold the angle longer. 

Anran is a fun, fiery flanker and should be a favorite for anyone who favors fast firefights

Anran will be playable tomorrow in a hero trial ahead of the Season 1 launch. She’s the sister of support hero Wuyang, and joins the new flanker subrole alongside damage heroes like Genji, Sombra and Tracer. Like them, Anran quickly moves around the map and attacks from unexpected angles. Her kit is built around inflicting the burning status, which she can further exploit with secondary fire that does additional damage to burning enemies. Fanning the flames also works on enemies burning from other sources, like Ashe’s Dynamite ability. 

Like most flankers, she has a movement ability and another ability that can be used more defensively. Her two-charge dash ability helps build up the burning status, and her Dancing Blaze ability makes her briefly invulnerable while damaging enemies in a small radius. 

Anran’s ultimate ability is perhaps the most unique part of her kit. She can use it offensively in battle to leap into the sky and release an explosion that damages and instantly burns enemies. Or, if Anran is killed while her ultimate is charged, she can use it to resurrect herself in a small explosion. I think it’ll generally be better to attack with her ultimate, but trading one-for-one on a flank and then using it to revive yourself also seems viable. 

Playing Anran was my favorite part of the playtest. It took me a few minutes to put together the flow of her kit, but once it clicked for me, I loved the fluid gameplay loop of getting in and dealing quick bursts of damage before getting out. While I struggled with the short range of her secondary fire and I consistently overestimated the range of her Dancing Blaze ability, her kit felt interesting and dynamic. I expect to play lots of Anran very soon. 

Emre is a lethal supersoldier with tactical gameplay and a terrifying ultimate

Emre is another damage hero who fits the soldier archetype, but unlike Soldier: 76, his kit features less running and more gunning. His primary fire is a hitscan, three-round burst rifle with remarkably little recoil. Aiming down sights doesn’t slow Emre’s movement speed, making him tricky to take down in an honest 1v1 at range.

One of Emre’s abilities pulls out a semiauto pistol that deals life-stealing explosive damage. He can also run faster and jump higher while the pistol is out. His other ability throws a grenade that will bounce once before detonating, allowing you to confirm kills around corners or chip away at an enemy’s health at the start of a skirmish — or just add a little height to your own jumps. His passive ability makes his health regeneration kick in sooner, with a 30 health burst when it starts.

Emre’s ultimate grants him the ability to fly as he pulls out a massive cannon to bombard enemies below him, firing light rounds constantly and pumping out larger blasts on a short cooldown. Those larger blasts are particularly devastating, especially to clusters of enemies or anyone trapped in a small space. 

Emre felt strong in the playtest, able to confirm kills at range by scoping in, while being very self-sufficient up close thanks to the life-stealing rounds on his pistol ability. His ultimate was the second-most-feared thing in the lobby (behind a certain feline screech), capable of wiping entire teams if they didn’t have an ultimate to respond with. Overall, Emre brought back memories of Halo glory days, chucking ‘nades and mowing down enemies with a battle rifle.

New heroes arrive just in time for Overwatch’s big, year-long narrative 

Overwatch has never released this many heroes at once. Even the launch of Overwatch 2 only brought us three new heroes — one from each role. It’s an exciting time for the game, with heroes released once per season as the game introduces a new, ongoing Reign of Talon narrative that each of the new heroes will tie into, on one side of the Overwatch versus Talon conflict or the other.

The new Season 1 kicks off Tuesday, Feb. 10, launching with all five of the heroes featured here.

NASA Used AI to Drive Its Perseverance Mars Rover for the First Time

NASA used Anthropic’s Claude for an experiment in plotting the rover’s course, which the agency deemed successful.

Plotting a course for NASA’s Perseverance rover, 140 million miles away on Mars, is significantly more difficult than setting a driving route here on Earth, where we can punch an address into Google Maps and be on our way in seconds. The rover’s course is usually plotted by a team at NASA’s Jet Propulsion Lab to account for terrain, obstacles and potential hazards, lest the rover tip over or get damaged. 

For the first time, NASA’s JPL used AI to plot a course for Perseverance, and it seems to have worked out. 

The two demonstrations, which took place on Dec. 8 and 10, were plotted by Anthropic’s Claude AI models and double-checked by JPL to ensure that the AI didn’t accidentally drive the rover into a ditch. Perseverance drove just under 1,500 feet across the two drives with no documented issues. 

NASA took a similar approach with plotting the waypoints as it would with human operators. Claude was fed the same satellite imagery and data from NASA’s Mars Reconnaissance Orbiter that JPL scientists would use, and then asked to plot waypoints that Perseverance could handle safely. 

The resulting path was slightly modified by NASA and then shipped to Perseverance, which then drove the path autonomously. 

«This demonstration shows how far our capabilities have advanced and broadens how we will explore other worlds,» said NASA Administrator Jared Isaacman. «Autonomous technologies like this can help missions to operate more efficiently, respond to challenging terrain and increase science return as distance from Earth grows. It’s a strong example of teams applying new technology carefully and responsibly in real operations.»

You can watch the Dec. 10 drive on NASA’s YouTube channel, which has been condensed into a 52-second video.

A more efficient way to do it

While AI is largely known as a provider of slop, which has been blamed for rapidly degrading people’s internet experience, it can be useful in some scientific pursuits. It takes time to parse years of imagery and data, plot the Perseverance waypoints, and then execute them. 

Per NASA, waypoints are usually set no more than 330 feet apart, which means Perseverance is exploring the red planet one football field at a time. Take its epic climb out of the Jezero Crater in 2024. The journey took Perseverance 3.5 months and, all told, the rover climbed a total of 1,640 vertical feet. As of December 2025, the rover has driven a total of just 25 miles in roughly four years.

The goal, according to JPL space roboticist Vandi Verma, is to let Perseverance (and other Mars rovers) travel much farther while «minimizing operator workload.» 

Verma also notes that AI could be used to flag interesting features on the planet, saving the human science teams time by eliminating the need to manually check «huge volumes of rover images.»

«This demonstration shows how far our capabilities have advanced and broadens how we will explore other worlds,» said Isaacman. «Autonomous technologies like this can help missions to operate more efficiently, respond to challenging terrain and increase science return as distance from Earth grows. It’s a strong example of teams applying new technology carefully and responsibly in real operations.»
