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.

Best battery packs with built-in Lightning cables and foldout wall plugs

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.
David Carnoy/CNET
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.
David Carnoy/CNET
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.
David Carnoy/CNET
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.
David Carnoy/CNET
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.

The Apple Watch Series 11 Could Share the Stage at Next Week’s Event
The Series 11 will likely headline, but rumors and iOS clues point to additional models joining the lineup at Apple’s September 9 launch event.

All eyes are on Apple’s September 9 «Awe Dropping» event, where a fresh batch of Apple Watches is expected to take center stage alongside the new iPhone 17 lineup. While the Series 11 will almost certainly headline, Apple may have already tipped its hand on the next Ultra. Imagery found in the iOS 26 public beta (first spotted by MacRumors ) shows display specs that don’t match any current model, and the two-year update cycle only strengthens the case that the rugged Apple Watch Ultra 3 is on the horizon.
With the clues stacking up, here’s a look at everything we know, suspect and can reasonably expect from Apple’s 2025 smartwatch lineup.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
How many Apple Watches will we get?
Based on the usual update cycle and now the latest clues in iOS 26, we’re at least getting a flagship (Series 11) and an Apple Watch Ultra 3 as revealed by a reference in Watch OS 26. Also likely is the possibility of getting a next-gen SE model, according to a report from Bloomberg’s Apple analyst Mark Gurman. The Apple Watch Ultra and the cheaper SE line haven’t exactly followed a predictable upgrade cycle but last year’s absence could prove a strong clue that 2025 could be the year that we get all three again.
According to Gurman, the new Ultra and Series 11 are mostly expected to look the same, while the SE could get a refreshed exterior. The Ultra could also get satellite connectivity and 5G RedCap network access that would bring even the most remote adventures «on the grid.»
Apple Watch Series 11 price and availability
Traditionally, new models go on sale anywhere from a few days to a couple of weeks after the keynote. This year, that could mean preorders opening on Friday, Sept. 12, with availability starting the following Friday, Sept. 19. That said, recent years have seen delays because of production issues and it’s still unclear how newly imposed tariffs might affect the launch timing and pricing in 2025. For context: the Series 10 starts at $399 for the base model, while the Ultra 2 comes in at $799. The other question is what the most expensive variant will be — solid gold, diamond-encrusted Hermès, anyone?
Apple Watch Series 11 design
The Series 11 is expected to keep the slim, flat-edged design introduced on the Series 10 (42mm and 46mm), but Apple’s new Corning partnership means all of the glass protecting the display will be made in the US. Not only does the news make for a great marketing bullet; it could also hint at improved durability, sustainability benefits and, potentially, faster repair turnarounds if replacement glass is sourced domestically.
If the leaked iOS 26 imagery holds true, the Ultra 3 will also have a similar design and slightly larger screen with a 422×514-pixel resolution (up from the Ultra 2’s 410×502 pixels). This could be achieved by slimming down the bezels while keeping the same overall case size, in keeping with Apple’s tradition of maximizing screen real estate without making the already-large Ultra any bulkier.
According to MacRumors, the Apple Watch could also get a more energy-efficient screen, maybe an improved LTPO display with higher resolution and better brightness, which, on paper, could help improve the battery life. This could be reserved for the higher-end Ultra 3, which will likely otherwise keep its original design.
Meanwhile the more affordable SE could see a more extensive design overhaul; it would keep the body of the Series 8 and, according to Gurman, get several upgrades from the Series 10, like an always-on display.
Apple Watch Series 11 processor
Apple typically bumps up the processor with every new smartwatch, so we should see an Apple S11 chip this time around for at least the Series 11 and Ultra 3. The Ultra 3 is also rumored to get satellite connectivity and 5G support, but according to Gurman, these features likely won’t make it to the Series 11. Considering last gen’s upgrade cycle, my personal bet would also be on the SE getting a processor bump up to the S9 chip, currently found in the Ultra 2 and the Apple Watch Series 9.
Apple Watch Series 11 battery
If there’s one thing on everyone’s wishlist, it’s better battery life. The Series 10 introduced faster charging — 0% to 80% in just 30 minutes compared with 90 minutes on previous models — but there’s room for improvement in battery capacity itself.
While there aren’t any rumors indicating that new Apple Watches will get a longer battery life, I truly hope Apple addresses the battery because its smartwatches are falling behind. Some Android models use dual chipsets to divide tasks and optimize battery life. I’d like to see Apple adopt a similar strategy and finally push battery life to two full days on a single charge for regular models. I hope the Ultra, which currently gets a full 72 hours on a charge, gets the faster charging of the Series 10 and pushes its battery life limits beyond three days.
Apple Watch health and fitness upgrades
There’s been a persistent rumor about blood pressure tracking finally making its way to the Apple Watch, but it’s unclear when it will be ready. According to a March report from Gurman, Apple has already been testing the feature in its smartwatch but has run into problems. Other wearables health companies like Omron and Med-Watch have proven it’s possible to measure blood pressure from the wrist, but adding this feature would likely require new sensors and a bulkier design. It would also be less precise than dedicated health devices like Omron’s and measure baseline metrics like the Galaxy Watch 7 and Ultra (which isn’t supported on Samsung watches in the US).
Blood pressure and glucose monitoring have also been thrown in the mix but the latter might not be fully baked for this cycle, according to Gurman.
A WatchOS glow-up on the Series 11
Apple also gave us a preview of the new interface for the Apple Watch with WatchOS 26 at its developers conference in June. The new UI update includes a new «Liquid Glass» display with glassy, transparent design language that mimics the one seen in visionOS.
The redesign features clear overlays for icons and notifications, resulting in a more uniform look and feel across Apple’s ecosystem. Google made a similar move with its redesigned UI, Material 3 Expressive, for Android phones and smartwatches with Wear OS 6.
Want a full breakdown of everything Apple announced, including the new iOS 26 and its eye-catching Liquid Glass design? Here’s everything you missed at WWDC 2025.
Health and fitness coaching
WatchOS 26 also introduced an AI-powered Workout Buddy to the Apple Watch, offering encouragement and real-time feedback during specific workouts. Most of the heavy lifting will happen on the iPhone, meaning the feature requires pairing the watch with a newer Apple Intelligence-enabled iPhone. The Series 11 (and Ultra 3) could push this further by leveraging their more powerful chipset.
This could include coaching that goes beyond just the workout app, potentially debuting on the Series 11 and then also rolling out to compatible Apple Watches. According to Gurman, Apple has been working on a major Health app revamp, code-named Project Mulberry, that would bring AI recommendations and actionable health and fitness insights to users. The new «Health Plus» app would likely arrive as part of an iOS 19 update, working in tandem with WatchOS 11 to gather and process data.
Health coaching is something other competitors, like Garmin and Fitbit, offer through their platforms via premium (paid) subscriptions. It’s not clear whether Apple would charge extra for these features, or if they’d be baked into the standard Health app at no additional cost.
Additional future Apple Watch surprises
There’s another rumor floating around that the Apple Watch could get a camera — not for selfies, but for AI-based image recognition. With the release of Apple Intelligence, Apple introduced a visual search tool on the iPhone that uses the camera to provide relevant information about objects and places.
According to a report by Gurman, Apple is exploring this option, and even if the company decides to move forward with the technology, it likely wouldn’t make its way to the Apple Watch until the 2027 models. While it’s not expected for this launch, it could hint what kind of AI integration will arrive with WatchOS 12. By contrast, WatchOS 11 lacks any Apple Intelligence features.
An even further-fetched clue hints at a foldable Apple Watch with two cameras. A recent Apple patent, first uncovered by Patently Apple, and published by the US Patent and Trademark Office in March, details an Apple Watch design featuring a foldable screen and another with a dual-screen display that either folds or slides out. The additional screens could give the Apple Watch more real estate to expand its functionality and make it less reliant on the iPhone. The same patent also points to the possibility of two cameras on this dual-screened watch for either AI processing or video calls. Apple often files patents well before any related technology appears in an actual product, so even if this concept does live to see the light of day, we’re not expecting it to make its public debut anytime soon.

Major Amazon Prime Benefit Faces Crackdown Next Month
Amazon plans to end its Prime Invitee program soon. Here’s how this could affect your deliveries.

If you’re using a friend or family member’s free Prime shipping and you don’t live in the same household, you might need to pay another monthly cost. According to Amazon’s updated customer service page, first reported by The Verge, the retail giant is ending its Prime Invitee benefit-sharing program on Oct. 1.
Amazon isn’t the first company to prevent membership sharing between family and friends. The e-commerce giant is just the latest to follow Netflix’s account-sharing crackdown. We also saw it done with Disney-Plus last year. While it’s unclear whether this change will work for Amazon, Netflix gained over 200,000 subscribers following its policy change.

Amazon’s Prime Invitee program is being replaced by Amazon Family, which includes many of the same benefits. However, Amazon Family only works for up to two adults and four children living in the same «primary residential address» — a shared home. While you’ll still be able to use free shipping to send gifts elsewhere, your Prime Invitees will no longer be able to use the perk.

What this means for you
If you’re the beneficiary of someone else’s Prime Invitee benefits, you have one more month to take advantage of the current program before the changes take effect.
Starting in October, you’ll have to get your own Amazon Prime subscription in order to benefit from the company’s free shipping program. First-time subscribers get a year of Prime membership for $15, but you’ll be stuck shelling out $15 a month to maintain your subscription thereafter.

Why is Amazon ending the Prime Invitee program?
This move follows shortly after Reuters reported that Amazon’s Prime account signups slowed down recently despite an extended July Prime Day event. While the company reported blowout sales numbers, new Prime subscriptions didn’t meet internal expectations. In the US, they fell short of last year’s signup metrics.
According to Reuters, Amazon registered 5.4 million US signups over the 21-day run-up to the Prime Day event, around 116,000 fewer than during the same period in 2024, and 106,000 below the company’s own goal, a roughly 2% decline in both metrics.
By forcing separate households to have their own subscriptions, Amazon could be looking to attract more Prime accounts after previously failing to do so.
The new Amazon Family program (previously known as Amazon Household) offers Prime benefits to up to two adults and four children in a single home, including free shipping, Prime Video, Prime Reading, Amazon Music and more. The subscription also includes benefits for certain third-party companies, such as GrubHub.

Premiere Pro for Free: How Adobe’s New iPhone App Will Let You Edit Videos at No Cost
Adobe Premiere users will only have to pay for extra AI credits and cloud storage.

Thanks to social media apps like TikTok and Instagram, everyone is an video editor these days. And soon you won’t have to sit down at a laptop to use one of the most popular video editors on the market.
Adobe announced on Thursday that it is releasing a new video editing iPhone app named Premiere on Sept. 30. You can preorder the app now in the Apple App Store, with an Android app currently in development.
The iOS app should feel familiar to Premiere users, with its multitrack timeline and preview screen. The app can be used for all your usual video editing: trimming clips, overlaying audio and adding synchronized captions. You can also use Adobe’s new voice-to-sound effects tool and record voiceovers.
Premiere should be a big upgrade for Adobe users who have only used Premiere Rush, a barebones version of its video editor. As more content creators become mobile-first, Adobe is hoping to draw them in with revamped mobile apps.

You should be able to use the Premiere iOS app for free. Adobe says you may need to pay for generative AI credits and additional storage, like through Adobe Creative Cloud, though more pricing info is expected closer to the Sept. 30 launch. This is very different from the desktop app, which starts at $23 per month.
A truly free Premiere mobile app would be a win for content creators, especially for anyone who wants to explore editing in Premiere but doesn’t want to pay for another subscription.
In an era of mobile-first content creators, tech companies have raced to introduce user-friendly mobile editing apps. TikTok creators use the ever-popular CapCut, with Meta adding its own contribution, a new app called Edits. Adobe has long been the industry standard for professional content creation and editing, but its mobile offerings were usually less feature-packed versions of its flagship programs under different names.
That changed this year as Adobe released true mobile versions of Photoshop and Firefly AI. The new Premiere app helps Adobe make a competitive entrance in a crowded market, in addition to giving loyal Adobe users a new way to access their tools on the go.
Adobe has also been focused on integrating generative AI into its software. Premiere Pro got its first-ever AI tool, generative extend, which uses AI to add a few extra seconds to clips you upload. It’s meant to help smooth transitions between clips, particularly when you might have turned off the recording a smidge too early and need a few extra seconds of film.
AI is a contentious issue among creators, with some voicing concerns over the training and deployment of AI models. Adobe’s Firefly AI has been fully integrated into the new Premiere iOS app, though the company’s AI guidelines state that it never trains on customer data and that its AI-generated content is commercially safe.
