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 InstantGo 5000

Best power bank with integrated Lightning cable

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.

iWalk LinkPod Y2

Top generic portable charger with integrated Lighting cable

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).

Mophie Powerstation Plus With PD

Durable portable charger with integrated Lighting cable

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 Hub 4400

Best dual iPhone and Android portable charger

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 733 Power Bank

Best power bank that’s also a 65W charger

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

Anker 622 MagGo Magnetic Battery

Best magnetic battery with integrated stand

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.

Baseus Magnetic Wireless Power Bank

Best high-capacity magnetic wireless portable charger with flip-out kickstand

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.

MyCharge Superhero MagLock

Wireless battery charger

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.

Mophie Snap Plus Juice Pack Mini

Mophie wireless magnetic power bank

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 Powerstation 10K Stand with MagSafe

Best official MagSafe portable battery with kickstand

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.

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.

Anker 523 PowerCore Slim 10K PD

Slim high-capacity battery with USB-C fast charging

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.

Power bank that converts into wireless charging stand

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.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
