Best Portable Chargers and Power Banks to Buy for Android in 2023

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 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, the fast USB-C out charging makes spending the extra dough worth it if you have a USB-C to Lightning cable.

The 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.

If you're looking for a compact external battery pack for your Android smartphone (or iPhone), Mophie's pocketable Power Station Mini features a 5,000-mAh internal battery and 20-watt USB-C PD fast charging.

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.

Thanks to gallium nitride 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, which combines a 65-watt charger with a 10,000-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 65-watt charge for a laptop, you'll have to plug in just the laptop. 

This Anker model is basically 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). And a little LED indicator on the side lets you check the charge level at the press of a button.

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 USB-C to charge your Android device (or iPhone), it will charge at a faster rate of 12 watts. That's not as fast as a 20-watt USB-C power adapter, but it's faster than the usual 7.5 watts.

Mophie's magnetic power bank is similar to Anker's but is slightly slimmer (it's svelte for 5,000-mAh battery) and doesn't have an integrated flap that converts into a stand. While it's designed to adhere to the back of MagSafe-enabled iPhone or MagSafe cases, it comes with a "snap adapter" ring to stick onto the back of Android devices so they'll be magnet-friendly. 

Wireless charging speeds appear to be limited to 7.5 watts, but if you need a faster charge, you can connect a USB-C to USB-C cable to bump the speed up to 12 watts.

Otterbox 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.
