6 Best Power Banks for Apple Watch. Belkin portable power bank

Best Power Banks for Apple Watch

Apple Watch brings a host of utilities to the table. That said, the smartwatch offers average battery life, at best (unless you have the Ultra, of course). In particular, the wearable’s one-day battery life is a no-go, especially when you’re traveling. And with no power outlets to top up the device when you’re on the road, a wireless power bank for the Apple Watch would be a game changer.

That’s precisely what we’re going to talk about today. In fact, we’ve come up with a bunch of enticing options for your perusal. What’s more, the power banks listed below FOCUS on various aspects and use cases.

So, without any further ado, here are some of the best portable Apple Watch chargers to charge your Apple Watch while camping, hiking, or even road-tripping! But before that –

  • Get the most out of your wearable by picking up some must-have Apple Watch accessories.
  • Charge both your watch and phone simultaneously using 2-in-1 wireless chargers for iPhone and Apple Watch.
  • Protect your watch without adding much bulk by using slim Apple Watch cases.

Newdery Portable Apple Watch Charger

Capacity: Not applicable

Newdery Portable Apple Watch Charger

If you’ve already invested in a power bank and don’t wish to purchase one for your Apple Watch, the Newdery Charger will serve you well. To that end, it’s a small USB dongle that plugs into the USB-A port of your existing power bank to charge your Apple Watch.

The Newdery Charger for the Apple Watch is quite travel-friendly as it comes with no wires. As such, you don’t have to rack your brains untangling your Apple Watch’s charger on a trip. All you need to do is plug the accessory into your power bank and rest your Apple Watch on it.

The charger is superbly compact and is the size of a pen drive. As such, you can toss the accessory in a small corner of your bag. In fact, with the help of the lanyard, you can even hook it onto your bag’s zip or a keyring. This product can be a good fit to charge your Apple Watch while camping or hiking.

With over 22,000 reviews, the Newdery Apple Watch charger is a user favorite, thanks to its simple design and functionality. It lets you charge your Apple Watch without any hassle. That too, without burning a hole in your

Belkin Boost Charge 2K

Capacity: 2,000mAh

Belkin Boost Charge 2K

The Belkin Wireless Power Bank is a compact product exclusively made for your Apple Watch. It sports a tiny form factor and resembles a bar of soap. With simplistic features along with the MFi certification, you simply can’t go wrong with the Belkin Boost Charge 2K.

Belkin is synonymous with high-quality accessories. The company’s products are quite reliable, which is important for a lot of users. The ‘Made for Apple Watch’ certification on the wireless charger is the cherry on top since you can be assured that your Apple Watch won’t encounter any issues.

The Boost Charge Power Bank by Belkin is a great travel companion mainly due to its overall footprint. Its compact design is surely a boon and the 2,000 mAh capacity — while slightly low — is sufficient to juice up your Apple Watch a couple of times. Not to forget, it comes with LED indicators to give insights on the remaining battery backup.

Do note that the power bank charges via a microUSB connector. That’s quite disappointing, seeing how most devices ship with a Type-C port. As such, you’ll have to carry an additional cable when you’re traveling. We really wish Belkin introduces an updated version with a USB-C port.

LVFAN Portable Charger for Apple Watch

Capacity: 4,000mAh

LVFAN Portable Charger for Apple Watch

If you’re on the lookout for a compact wireless power bank with a capacious battery backup, then you should check out the LVFAN portable charger. It is more expensive than Belkin’s Wireless Power Bank, however, it offers double the battery power.

The LVFAN wireless power bank comes with a 4,000 mAh cell. In theory, it should be able to charge your Apple Watch twice as much as Belkin’s offering. What’s more, much like the Belkin Boost Charge 2K, the LVFAN portable charger also comes with built-in LEDs. notably, users cite that the charger’s magnetic puck is quite strong. As such, your Apple Watch will stay affixed to the puck even when you’re out and about.

Along with charging your Apple Watch more times, the LVFAN power bank also fixes pretty much the only con with the Belkin option as it comes with a USB-C port.

Latimeria Magnetic Wireless Charger

Capacity: 10,000mAh

Latimeria Magnetic Wireless Charger

Up next, is the Latimeria wireless charger that has a whooping 10,000mAh battery pack. What’s more, the company’s magnetic power bank brings a lot to the table and comes toting a 2-in-1 charging mechanism and a foldable stand.

Getting wireless power banks for all your tech can be a hassle. That’s where the LATIMERIA Magnetic Wireless Charger steps in. This 2-in-1 magnetic charger acts as a power bank for both your Apple Watch and iPhone. Just snap the power bank onto the back of your iPhone and it’ll juice up the phone in no time.

The added bonus of the LATIMERIA power bank is that it comes with a foldable rubber bracket. This lets you attach your phone in a vertical or horizontal orientation for a comfortable viewing experience. Do note that you can charge both, your phone and Apple Watch simultaneously if you affix your iPhone horizontally.

While the MagSafe magnets are strong, the large capacity means the power bank is rather heavy so you might want to be slightly careful when using your iPhone with the power bank attached.

iWalk Portable Charger

Capacity: 9,000mAh

iWalk Portable Charger

Are you looking for a wireless charging solution for your Apple Watch that can recharge your iPhone in a jiffy too? Then, you should give the iWALK portable Apple Watch power bank a second look. The integrated magnetic charger module and lightning cable offer the best of both worlds.

Wireless charging can be slow. It can be even more of a task if you want to charge your Apple Watch and iPhone simultaneously. The iWALK portable charger reserves wireless charging for your Apple Watch and goes the wired route for your iPhone. The built-in lightning cable plugs into your iPhone while a puck resting on the surface caters to your Apple Watch.

This also results in faster charging speeds for your iPhone along with better efficiency. Do note that some users have raised an eyebrow at the puck’s magnetic force that binds the watch to the power bank. Some have complained about the watch dislodging from the power bank too, which can be an issue if you’re traveling.

VRURC Magnetic Charger

Capacity: 10,000mAh

VRURC Magnetic Charger

Do you want to charge your entire Apple ecosystem wirelessly with a single power bank? Check out the VRURC Magnetic Wireless Charger. Along with a 3-in-1 charging solution, this product has a foldable Apple Watch charging puck which makes it a good power bank to have even on your bedside table.

The VRURC Magnetic Wireless Charger ups the ante and allows users to charge three devices at once. You can use a lightning cable to charge your iPhone. The Apple Watch and Airpods can be slotted on the two wireless charging surfaces.

While it is a great charging option when traveling, users of the VRURC wireless power bank claim that it is quite heavy, which can be attributed to the unit’s 10,000mAh battery capacity. It even comes with a foldable puck, that allows you to rest your Apple Watch and see the time as well. So you can also use it like a bedside clock in your hotel room when traveling.

Interestingly, VRURC’s Magnetic charger has a built-in Smart chip to detect overheating. This ensures a safe charging solution. All in all, if you camp a lot, the VRURC power bank is a great solution to charge not only your Apple Watch but also other Apple products.

Best MagSafe portable battery packs and power banks for iPhone 12, 13 and 14

Portable power banks that charge your phone are popular, but wireless battery packs using Apple’s MagSafe technology offer a simpler and smarter cable-free solution for iPhone 12, 13 and 14 users.

Phone batteries are prone to run dry just when you’re heading away from a power source, so having a portable charging source is one of today’s necessities. Annoyingly, most power banks require you to carry around a cable, too.

Wireless power banks do away with cables but come with their own major limitation–the inefficiency of wireless charging means you need a high-capacity power bank to fully charge a drained iPhone.

I use one as a quick bedside iPhone charger so I can charge and use the phone at the same time without having to worry about cable length. And of course I carry one around with me in my bag for on-the-move recharging.

MagSafe is a technology that’s compatible with all iPhone 12, 13 and 14 models, from the mini to the Pro Max. It allows accessories to connect magnetically to the back of the iPhone.

The MagSafe connection is precise enough to make wireless charging more efficient as around 20% of Qi power loss is from poor placement of a phone and the wireless charging pad. WStandard Qi wireless charging can lose as much as 50% of the portable battery’s power, MagSafe wireless charging loses ‘just’ 30%.

While it’s not as efficient as using a cable to charge a phone, MagSafe is a tech that brings true wireless charging a step closer to doing away with cables altogether.

We have tested the best MagSafe chargers to find which is the right one for you and your iPhone. Here we have tested the best MagSafe battery packs.

Certified MagSafe or MagSafe compatible

Not all are officially certified MagSafe by Apple but we’ve included only those MagSafe-compatible battery packs that work as efficiently as the “Made for MagSafe” models. Official certification is more important for wired MagSafe chargers as the 15W charging power of MagSafe-certified chargers beats the 7.5W maximum for mere MagSafe-compatible accessories.

In comparison, the portable battery packs tested here can’t reach 15W, except those that can be charged simultaneously by wire and wireless, as the Apple MagSafe Battery Pack can.

We have listed the speeds at which each portable power bank can be charged itself (Input charger) and charge the iPhone (Output charger).

We’ve also included a few alternative non-magnetic options, including standard power banks and battery cases. MagSafe is cool but it isn’t always the best option.

After the list of our favorites, you’ll find more details on how MagSafe works and why you should be looking at a power bank’s capacity in Watt Hours rather than the mostly quoted Milliamp Hours.

Apple MagSafe Battery Pack – Smartest MagSafe battery

  • MagSafe
  • Compact
  • Smarter battery features than rivals
  • Cable plus wireless charging (15W)

Capacity: 11.13Wh (1460mAh/2920mAh)

Input charger: Lightning (27W)

Output charger: Wireless (5W) Lightning (15W combined)

MagSafe: Certified

Tested: Yes

Charged drained iPhone to: 60%

Weight: 114g

Dimensions: 9.6-x-6.4-1.1cm

Colors: White

Compatibility: iPhone 12/13 mini, iPhone 12/13/14, iPhone 12/13/14 Pro, iPhone 14 Plus, iPhone 12/13/14 Pro Max

Compatible with all models of iPhone 12, 13 and 14, the Apple MagSafe Battery Pack is an intelligent and convenient lightweight power pack that magnetically clamps to the iPhone.

While underpowered compared to the competition, it will charge a fading iPhone up to around 60%, which should be enough to get you through the day to when you have access to a power outlet.

Wireless charging isn’t the speediest at 5W, but unlike most other MagSafe chargers, the Apple Battery Pack can charge an iPhone at 15W using a wireless and a Lightning cable simultaneously.

Its Apple advantage is its Smart features that show onscreen battery power icons and safety features that stop charging when too hot or before the phone’s internal battery could be compromised – meaning it’s good practice to stop charging a phone battery at 90% for long-term battery health.

Available in white only, the Apple MagSafe Battery Pack is smarter but more expensive compared to third-party alternatives.

Belkin BoostCharge Power Bank 5K Stand – Best MagSafe battery pack with stand

Compatibility: iPhone 12/13 mini, iPhone 12/13/14, iPhone 12/13/14 Pro, iPhone 14 Plus, iPhone 12/13/14 Pro Max

The battle to be the best MagSafe-compatible power bank that also boasts a kickstand is a close run thing between the Belkin BoostCharge and the Anker MagGo 622. Both have 5000mAh batteries but the Belkin won in our head-to-head tests, recharging a faded iPhone 13 Pro by 90%, compared to Anker’s 80%.

The Belkin’s kickstand is easier to use and feels more robust, and the battery pack itself is marginally smaller. We still love the Anker 622 but the Belkin wins the battle of the MagSafe kickstand power banks.

It also beats Apple’s 5W wireless charging with 7.5W when clamped to the back of an iPhone, and while it doesn’t hit 15W on simultaneous wired and wireless charging like the Apple MagSafe Battery Pack, it can be charged with a cable at a chippy 10W.

The Pink and Purple colors are available in the U.S. only. Everyone else gets either Black or White models to choose from.

Anker MagGo 622 Magnetic Battery – MagSafe battery pack with stand

Capacity: 19.13Wh (5000mAh)

Input charger: USB-C (12W)

Output charger: Wireless (7.5W)

MagSafe: Compatible

Tested: Yes

Charged drained iPhone to: 80%

Weight: 146g

Dimensions: 10.5-x-6.6-x-1.3cm

Colors: White, Gray, Purple, Green, Blue

Compatibility: All iPhone 12, 13 and 14, except mini

The Anker MagGo 622 Magnetic Battery is cheaper than the Apple MagSafe Battery Pack, has a larger battery capacity and is available in multiple muted colours: white, purple, green, blue and gray.

It works with all MagSafe iPhone, but sits a little over the smaller iPhone mini when magnetically attached.

We love that the Anker 622 comes with its own built-in fold-out stand, which with MagSafe’s pulling power will hold your iPhone securely in either portrait/vertical or landscape/horizontal mode. The Belkin BoostCharge 5K, reviewed above, has a tougher metal pull-out stand, and also offer another 10% of charge on the better-looking Anker 622.

The stand folds away so that it can be popped in a to be magnetically clamped to the phone when you need it most – and operates just like the Apple battery pack.

In our battery tests, the 622 managed to charge a drained iPhone to 80% of full power, which is a significant jump on Apple’s MagSafe Battery Case and the UAG Lucent Charger (also with kickstand) that both powered the iPhone to just 60%.

The Anker battery is rated at 19.13Wh (5,000mAh) but, like all the other wireless chargers loses a decent chunk of that power to environmental factors. As its battery is larger than Apple’s, it actually loses a little more but has plenty in reserve to make up for this.

The Anker battery charges wirelessly at 7.5W–faster than Apple’s 5W charge, although the Apple battery can use the wireless Qi and cabled USB-C power simultaneously to speed charging at up to 15W.

It ships with a 60cm USB-C cable.

UAG Lucent Wireless Portable Charger with Kickstand – Best small magnetic power bank

Capacity: 15.4Wh (4000mAh)

Input charger: USB-C (18W)

Output charger: Wireless (7.5W)

MagSafe: Compatible

Tested: Yes

Charged drained iPhone to: 62%

Weight: 129g

Dimensions: 10.5-x-6.6-1.3cm

Colors: Black, Deep Ocean, Marshmallow, Orchid

Compatibility: iPhone 12/13 mini, iPhone 12/13/14, iPhone 12/13/14 Pro, iPhone 14 Plus, iPhone 12/13/14 Pro Max

A third-party alternative to Apple’s MagSafe Battery Pack is Urban Armor Gear’s Lucent Wireless Portable Charger. Like the Apple Battery Pack, it’s not the highest capacity battery on test here, but it is dinky—just a little larger and heavier than Apple’s.

The battery capacity appears a lot larger in the specs, but Apple’s Smart magic means they both tested in real life around the same–raising a dead iPhone to just over 60% charge.

This UAG portable magnetic charger beats Apple on having a handy built-in kickstand and a choice of colors, as well as faster charging at 7.5W. And it’s also a decent amount cheaper.

It ships with a 1m USB-C cable, although it’s old-school USB-A on the wall-plug end.

Moft Snap Stand Power Set – Best wallet/stand magnetic battery pack

Capacity: 13.1Wh (3400mAh)

Input charger: USB-C (10W)

Output charger: Wireless (7.5W)

MagSafe: Compatible

Tested: Yes

Charged drained iPhone to: 50%

Weight: 120g

Dimensions: 9.9-x-6.6-x-1.2cm

Colors: Black, Blue, Brown, Purple

Compatibility: iPhone 12/13 mini, iPhone 12/13/14, iPhone 12/13/14 Pro, iPhone 14 Plus, iPhone 12/13/14 Pro Max

The Moft Snap Stand Power Set is a clever combination of magnetic battery pack with a detachable stand that also holds up to three travel or credit cards.

The supplied USB-C cable also links magnetically to the battery pack, which will charge a connected iPhone first before the power bank itself. While the battery pack offers only a 50% charge, that will likely be enough for most trips away from a fixed power source. If you need more portable battery capacity, look at an alternative such as the Anker MagGo 622 (80% charge).

It is MagSafe-compatible but curiously boasts a usually only-MagSafe-certified feature, where there’s a visual representation of available charge on the iPhone itself.

Anker MagGo 633 Magnetic Wireless Charger – Best multi-function MagSafe charger

  • Battery capacity
  • Portable power bank and dual-device charging stand
  • 7.5W
  • Colors

Capacity: 19.13Wh (5000mAh)

Input charger: USB-C (25W)

Output charger: Wireless (7.5W)

MagSafe: Compatible

Tested: Yes

Charged drained iPhone to: 84%

Weight: 132g

Dimensions: 10.6-x-6.6-x-1.2cm

Colors: White, Blue, Gray

Compatibility: All iPhone 12, 13 and 14, except mini

The Anker MacGo 633 Wireless Charger is more than just a MagSafe charger. It’s also an adjustable stand that charges the iPhone when in place, and also keeps the 633 battery charged for when you need to slip it out of its holster for portable use.

And the base of the stand is also Qi-enabled so can wirelessly charge an Airpods case or similarly sized Qi-ready device.

As a portable battery charger that magnetically attaches to the iPhone it is similar to its non-charge-stand sibling, the Anker MagGo 622. And it has the same 19.13Wh (5000mAh) battery that offers a greater charge potential than Apple’s own MagSafe Battery Pack.

In our tests, it charged an empty iPhone 13 Pro up to 84%, beating the 622’s 80% and Apple’s 60%.

It charges the iPhone at a decent 7.5W–the same as the 622 and 1.5x better than the Apple – and comes with a 25W wall charger and 1.5m USB-C cable.

The Anker MagGo 633 is great value as it offers so many functions: desktop charger, portable power bank, Airpods charger, and adjustable viewing stand, and is doesn’t compromise on any of those roles.

ESR HaloLock Kickstand Wireless Power Bank

Capacity: 37Wh (10000mAh)

Input charger: USB-C (18W)

Output charger: Wireless (7.5W), Wired (20W)

MagSafe: Compatible

Tested: Yes

Charged drained iPhone to: 149%

Weight: 219g

Dimensions: 10.4-x-6.9-x-2cm

Colors: White, Black

Compatibility: All iPhone 12, 13 and 14

The ESR Halolock Kickstand Wireless Power Bank might not mention its magnetism in its name, but it is a worthy alternative to Apple’s MagSafe Battery Pack.

It’s MagSafe compatible rather than certified, so charges at 7.5W instead of 15W, but its 10000mAh battery capacity is significantly greater.

It also boasts a robust metal kickstand that can be used in both portrait and landscape modes.

That and its giant capacity positions it as a competitor to the SWIO/CAVN Magnetic Wireless Portable Charger (reviewed above). While it’s more expensive, it did power our faded iPhone for longer and has a tougher kickstand. It’s also a little smaller, but a tiny bit heavier.

Passthrough charging lets you charge your phone and power bank at the same time.

SWIO Magnetic Wireless Portable Charger – Highest capacity attachable MagSafe battery pack

Capacity: 38.5Wh (10000mAh)

Input charger: USB-C (22W)

Output charger: Wireless (7.5W) USB-C (22W combined)

MagSafe: Compatible

Tested: Yes

Charged drained iPhone to: 136%

Weight: 210g

Dimensions: 10.4-x-6.6-x-2.1cm

Colors: Black, Blue

Compatibility: All iPhone 12, 13 and 14 models

The SWIO/CAVN Magnetic Wireless Portable Charger boasts a giant battery, with 38.5Wh (10,000mAh) capacity. This colossal capacity means it is a bit of a colossus itself, significantly fatter than other portable chargers tested here.

It’s chunky thickness will fit in a while clamped to a phone but only just. It’s more a charger on the table type of power bank.

Indeed, with its handy built-in stand, you can settle down to watch a movie while your phone is re-energized.

It recharged our test iPhone 13 Pro to 100% and then another 36% above that, so it can charger a couple of flagging phones, or iPhone and Airpods (via cable), or just keep juice spare for a decent top up later. It will charge a non-Pro 12, 13 or 14 even further. It’s even capable of giving a respectable charge to an iPad Pro.

iWalk Magnetic Wireless Power Bank – Best MagSafe battery with LED display

Capacity: 22.2Wh (6000mAh)

Input charger: USB-C (18W)

Output charger: Wireless (7.5W), USB-C (18W)

MagSafe: Compatible

Tested: Yes

Charged drained iPhone to: 105%

Weight: 158g

Dimensions: 10.3-x-6.5-x-1.8cm

Colors: Black, White, Pink

Compatibility: All iPhone 12, 13 and 14 models

The iWalk Magnetic Wireless Power Bank has a couple of features not found on other magnetic battery packs.

The most obvious is the finger ring, which is meant to mean safer holding but we prefer to grip our phone using a whole hand. But it does double-up as a kickstand for the iPhone so you can place it in a horizontal/landscape viewing position–horizontal feels more stable.

Even more useful is the LED battery-charge indicator that shows you exactly how much charge is in the power bank. This is way more helpful than the usual array of four tiny LEDs that most battery packs come with and especially more informative than Apple’s single Orange (not full) or Green (full) LED that lights up only when cable- connected to a power source.

The iWalk power bank also boasts a sizeable battery, with 2.2Wh (6000mAh) capacity. It recharged our test iPhone 13 Pro to 100% and then another 5% above that, so, in reality, a full charge with a little over for expected battery drain if left sitting in your bag for a few days. And it will charge a non-Pro 12, 13 or 14 even further.

As such, it’s heavier and fatter (including the pull-out ring) than most other magnetic power banks tested here.

It can charge while magnetically clamped to the iPhone and also (but not simultaneously) by USB cable at an impressive 18W, although you’ll need a USB-C-to-Lightning cable for wired charging.

it comes with a USB-C-to-USB-C cable for charging the pack itself, and also a Magsticker to attach to non-MagSafe phones for the same battery-pack functionality.

The Anker 737 features 140W output, which means it can charge bigger, more power-hungry devices like a laptop just as effortlessly as it can juice up a phone or tablet.

Who It’s For

If you often need to charge a laptop when you’re nowhere near an outlet, this 24,000mAh backup battery can lower your stress levels. It’s more expensive than other options on this list, so people who tend to charge smaller devices like phones or tablets are better off with the more affordable choices.

Who It’s For

If you spend a lot of time outdoors, this is among your best choices for keeping your devices running while off of the grid. In other words, it’s camping approved.

What Size Battery Do You Need?

On the.friendly front, most smaller batteries have a capacity of around 5,000mAh, which is typically enough to top up most phones once.

Meanwhile, a 10,000mAh battery can give today’s flagships two full charges. A 20,000mAh battery can charge a flagship four times, or two phones two times. Some power banks have enough juice to power laptops. Of course, a higher capacity often translates to a heavier, larger, and more expensive battery.

Most companies advertise how many times their products can recharge popular phones, but if you want to calculate that number for yourself, RAVPower has a useful guide (Opens in a new window) that can give you an estimate.

In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty.

What’s the Difference Between Power Input and Output?

You’ll find three types of ports on today’s portable batteries:

Generally speaking, you charge the battery itself via micro USB or USB-C (input). Some batteries charge faster than others and USB-C charges much faster than micro USB.

Nearly all batteries include a standard USB-A port (output). This is for plugging in USB-A-to-micro-USB, USB-A-to-Lightning, or USB-A-to-USB-C cables for charging your iPhone or Android device.

Some batteries include built-in output cables and these generally have micro USB, USB-C, or Lightning connectors.

The most important thing to do is to match the battery’s output to your phone’s input. For example, if you have an iPhone, be sure the battery has its own Lightning connector or supports USB-A-to-Lightning or USB-C-to-Lightning cables.

Larger batteries with higher capacities might include a multitude of ports to support input and multiple outputs at the same time. You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common.

What Is Fast Charging?

Another factor to consider is how quickly a power bank can charge your device. Battery output is measured in voltage and amperage. Amperage (or current) is the amount of electricity that flows from the battery to the connected device, while voltage is the amount of potential energy. Multiplying volts by amps gives you wattage, the measure of total power. To make devices charge faster, most manufacturers either vary the voltage or boost the amperage.

Today’s devices support a wide range of Rapid-charging technology, such as Qualcomm QuickCharge, USB Power Delivery, or proprietary fast-charge systems.

Quick Charge works by increasing voltage rather than amperage. This standard typically allows you to charge supported phones to 50 percent capacity in 30 minutes, which is especially helpful when you need power in a pinch.

Power Delivery is a newer protocol in which two compatible devices negotiate on the fastest charging option available based on the charger, cable, and circuitry. It also allows for power to flow both ways.

The most common devices (Apple iPhones and Samsung Galaxies) support charging rates of 27W and 45W, respectively. It’s best to look for batteries that can support charging in that range.

Is Pass-Through Charging Safe and Useful?

Pass-through charging is another feature to consider; with it, you can charge devices and the portable power bank simultaneously. That’s convenient if both your phone and backup battery are running on empty. You shouldn’t encounter any safety issues if the manufacturer of the portable battery you buy advertises pass-through charging as a feature, but the power output might change in this mode.

How Does Wireless Charging Work?

Wireless charging has become popular because it allows you to power up compatible devices without a cable. Qi is the dominant standard for compatible Android phones (up to 18W) while Apple iPhones rely on MagSafe charging (up to 15W). iPhones will charge wirelessly on Qi chargers, but only at 7.5W.

Some battery makers have built Qi or MagSafe-compatible wireless charging into the surfaces of their portable batteries. Such batteries mean you can leave the cables at home.

Should You Buy a Battery Case Instead of a Power Bank?

If you find that you often forget to carry your backup battery when you need it most, you should consider a dedicated battery case instead. These combine the portability and protection of a case with additional battery capacity to keep your phone topped off at all times.

There are several drawbacks. First, they have limited additional capacity on board. Second, they are limited in terms of the number of phones they support (mostly just iPhones, Galaxies, and Pixels). Third, you can’t charge much else with them.

The Best Wireless Chargers

Why fumble around for a charging cable when you can rest your phone on a wireless charging pad? Whether you’re an Android user or an iPhone fan, check out our roundups of the best wireless chargers and the best MagSafe chargers to help you cut the cord.
