Losing power of your devices like your iPhone, Android phone or tablets is never fun, especially when you're out and about. Considering how much we rely on our phones, a low battery level isn't just inconvenient; it's dangerous, too. To avoid situations like this, you might want to consider investing in a portable charger that gives you the ability to juice up anytime, anywhere.
Though you could go with a battery case, they're bulkier than a regular case and can affect wireless charging and reception. And the worst thing is that they're limited to specific phone models. It's an option if you plan to use one phone for a long time, but portable battery packs and chargers are a better option. You can use a slimmer phone case but still have a charger stashed away, ready when you actually need it.
Here are some of our top picks for Android power banks. Though we say Android power banks, most of these will also work just fine if you have an iPhone with a USB-C port (the iPhone 15 onward). Our favorite kinds have built-in USB-C cables, which eliminate the need to carry around separate cables. If you have an iPhone with the older Lightning cable, we have a separate guide to the best iPhone chargers and power banks.

Best portable chargers and power banks for Android of 2025 ProsInfinity 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 USB-C cable for easy charging for phones. The larger 10,000-mAh model costs a bit more and is heavier and bulkier, but it can charge most Android smartphones twice. Although the white model is currently unavailable, the black one is in stock.
ProsThe 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 outport. The Anker 313 PowerCore Slim 10K is cheaper, but the fast USB-C outcharging makes spending the extra dough worth it if you have a USB-C to Lightning cable.
ProsThe Anker PowerCore III 10K portable charger has fast USB-C out charging (18 watts), as well as a USB-A port and up to 10-watt wireless charging. It's not magnetic, so your phone won't stick to it but it will wirelessly charge any Qi-enabled devices.
ProsIf 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.
ProsThanks 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 that the company says is even more energy-efficient. The Anker Power Bank 733, combines a 65W charger with a 10K mAh portable battery, 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'll have to plug in just the laptop.
ProsThis Anker model is effectively an oversized wall charger with a built-in 5,000-mAh battery. It's got two standard USB charging ports for simultaneously juicing up your phone and a secondary gadget (or two phones). A little LED indicator on the side lets you check the charge level at the press of a button.
ProsWhat'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.
Note that Anker has updated this model to move the charging port to the side (from the bottom), so you can charge it while using it as a stand. Do not buy the old version that confusingly retains the same 622 model number.
ProsMophie's magnetic power bank is similar to Anker's but is slightly slimmer and doesn't have an integrated flap that converts into a stand. Like the Anker, this 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 5,000-mAh battery. It can also be used with other phones that support wireless charging as it comes with a stick-on magnet.
Wireless charging speeds are limited to 7.5 watts for iPhones, but if you need a faster charge, you can connect a USB-C to Lightning cable to bump the speed up to 12 watts. This has enough juice to fully charge an iPhone 13 or 13 Pro once, but it'll fall a little short of a full charge with an iPhone 13 Pro Max.
ProsMyCharge'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 to almost fully charge your smartphone, depending on its size.
ProsOtterbox gears its Folding Wireless Power Bank 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.
BudgetBefore anything else, you'll want to figure out how much you're willing to spend on a portable charger or power bank. Value-priced chargers continue to improve, so you can find a decent wireless charger for less than $40. If you're looking for a more premium model, you'll likely have to pay more than $50 and even more for Qi-enabled chargers.
Power capacity vs. weightMost baseline power banks now start at a 5,000-mAh capacity, which should give you at least one full charge for an Android phone. Chargers with 10,000 mAh or more are available, but they weigh more. That's of particular note if you plan on traveling with the charger in a purse, backpack or pocket.
Wireless or corded charging?Most Android phones since the Samsung Galaxy S6 and Galaxy S6 Edge models introduced in 2015 offer inductive wireless charging. Android's standard for these phones is called Qi, and power banks that are fully Qi-compatible offer faster charging speeds for Android devices with speeds capped at around 7.5 watts for iPhones. In all cases, you'll need to make sure your phone case is thin enough to allow inductive charging through the back of the phone.
At the current time, we do anecdotal testing on these models. Each is fully charged and used on a recent Android model for at least a week in real-world conditions. We verify that charging speeds and recharge times are within expected parameters and -- for models with integrated stands or cables -- confirm that the connections and build quality are sturdy and free of any notable annoyances or caveats.
Anker MagGo Power Bank 6.6K: The Anker MagGo Power Bank 6.6K has a 6,600-mAh battery that can fully charge most iPhones once. It's Qi2-certified, which means it offers 15-watt fast charging capabilities and is fully MagSafe compatible, offering twice the speed of standard 7.5-watt wireless chargers for MagSafe-enabled iPhone 13, 14 and 15 models and Android smartphones that support 15-watt wireless charging.
Anker Nano Power Bank (USB-C): This 5,000mAh power bank weighs in at 3.5 ounces, or 100 grams. It features 22.5 watts of fast charging power with the option to charge two devices at the same time if you plug a cable into the power bank's USB-C in/out charging port. (Charging two devices simultaneously divides the charging power in half, delivering 11.25 watts to each device.)
myCharge Hub 6700 (Discontinued): MyCharge's Hub portable chargers come in a few different sizes and not only have an integrated foldable wall plug but also integrated Lightning and USB-C cables, so you can charge both Apple and Android devices. It's a little bulky, but with a 6,700-mAh battery, it should be able to almost fully charge your smartphone, depending on its size. The step-up 10,050-mAh model is still available and about $25 more.
Nimble Champ: Nimble's updated Champ portable charger uses recycled plastic in its construction. You have to pay a bit more for going green, but it's a nice, compact 10,000-mAh charger that features 20-watt PD fast-charging with dual USB-C ports (one on either side of the power bank) that allow you to charge two devices at the same time. If you are charging two devices, your charging speeds will be limited to 10 watts per device.
Can these Android power banks charge other devices too?Yes, these power banks should charge any device that's USB-powered, such as phones, headphones, ebook readers and Bluetooth speakers. Some may also charge larger devices such as tablets and the Nintendo Switch, albeit at slower speeds. You'll stand a better chance of charging the larger devices if you get a charger with USB-C PD support. Don't expect to charge laptops or Chromebooks without getting larger, higher-capacity power banks that are specifically designed for that purpose (with 65 watts of power output or more).
Show more What's the difference between USB-C and USB-A?Power banks for Android invariably have USB inputs and outputs for charging themselves and other devices, respectively. (Some power banks have single ports that double for both.) The USB-A port is the "classic" rectangular USB port that's been on computers since as early as the late 1990s. The newer, smaller USB-C port is reversible (there is no "top" or "bottom" to the plugs) and has the capacity to charge at higher speeds. Some power banks have integrated cables that terminate with Lightning (iPhone-specific) or USB-C cables.
Show more What's the difference between MagSafe and Qi?MagSafe for iPhone -- not to be confused with the identically named magnetic power connector for MacBooks -- is an Apple standard that allows for inductive charging with magnetically attached batteries. Qi wireless chargers don't necessarily have a magnetic component but also allow for inductive charging. Devices that are Qi-2 certified offer twice the speed of standard 7.5-watt wireless chargers for MagSafe-enabled iPhone 13, 14 and 15 models and Android smartphones that support 15-watt wireless charging.
Show more What does mAh mean on a power bank?The mAh on a power bank stands for milliampere-hour which represents the storage capacity of a battery. The higher the mAh rating, the more power the power bank can store.
Show more What is the largest power bank allowed on a plane?Most airlines allow batteries of up to 100Wh or approximately 27000mAh on a flight. Larger batteries or power banks will require special permission from an airline.
