Samsung Galaxy Note 10 20,000mAh power bank charging on the sofa

A power bank is a great way to keep your devices charged while away from an outlet. You can get smaller portable batteries with 5,000mAh and 10,000mAh capacities, but those with 20,000mAh will last you longer and should charge your device several times. Here are our recommendations for some of the best 20,000mAh power banks you can currently get your hands on.

Best 20,000mAh power banks:

Editor’s note: We will continually update this list as new 20,000mAh power banks are announced.


1. RAVPower 20,000mAh portable battery

Costing a penny shy of $50, RAVPower’s 20,000mAh portable battery features separate micro-USB and USB-C inputs. There’s also a second USB-C port for Power Delivery output. In this case, that means the portable battery can output up to 18W.

Rounding out the port selection are two regular USB ports, with one supporting Quick Charge 3.0. The other USB port supports RAVPower’s iSmart charging technology with 2.4A output. There’s even a small display to show how much charge the portable battery has left.


2. Anker PowerCore Speed 20000

Anker has several 20,000mAh power banks, but one notable option is the PowerCore Speed 20000. The battery features a regular USB port for output, along with a USB-C port for input and output. Thanks to support for Power Delivery, the USB-C port delivers up to a 24W output.

Anker’s pedigree and the fast-charging capabilities are already good enough, but this option also includes a 30W wall charger. The beefy wattage takes the PowerCore Speed 20000 from zero to full in four hours. Also keep in mind you can use it to charge other USB-C devices, such as tablets, smartphones, and even certain laptops.

At just under $100, the PowerCore Speed 20000 is not a cheap option. However, the beefy portable battery, PD support, and inclusion of a 30W wall charger makes the bundle worth the money.


3. Aukey 20,000mAh power bank

If you’re looking for a 20,000mAh power bank that doesn’t lack in port selection, look no further than Aukey’s offering. The battery features three regular USB ports for output, a micro-USB port for input, a USB-C port for input and output, and even a Lightning cable for input.

The battery doesn’t support Power Delivery, but you still get 15W output for the USB-C port. Also keep in mind you can’t use USB-C to Lightning cables to charge the battery. That means you’ll need to use a normal Lightning cable to get the job done.

Even with the caveats, the $39.99 price is hard to ignore for a battery this size and with this many ports.


4. Mophie Powerstation XXL

Mophie Powerstation XXL 20,000mAh power bank

At first glance, the Mophie Powerstation XXL is a by-the-numbers portable battery. There are two regular USB ports and a USB-C port for input and output. The port selection isn’t varied, but at least the USB-C port can output at 15W.

Where the Powerstation XXL differs from the competition is in material choice. The fabric material on the top and bottom is soft to the touch, even if you might need to clean it from time to time. 20,000mAh power banks

At around $61, the Powerstation XXL is a bit more expensive than a few other options. However, it’s a straightforward portable battery that doesn’t try to be more than that. For some people, that’s enough.


5. Zendure A6PD 20,100mAh power bank

It’s easy to not think much of the Zendure A6PD. After all, there’s only one micro-USB port for input, one regular USB port for output, and one USB-C port for input and output. However, this portable battery has an impressive trick up its sleeve: 45W charging.

Yes, you read that right: the USB-C port supports 45W input and output. That means you can charge larger devices like the 15-inch MacBook Pro. Even the regular USB port delivers up to 18W of output, thanks to Quick Charge 3.0. These are charging speeds not often seen from portable chargers.

Also nice is the aluminum enclosure. Most portable batteries feature plastic enclosures, so it’s nice to see a higher-quality material used for the exterior. You’ll pay for the extravagance — the A6PD costs around $60 on Amazon.


6. Omnicharge Omni 20+

If you’re looking for a truly all-in-one portable battery, look no further than the Omnicharge Omni 20+. In addition to the two regular USB ports, the Omni 20+ features a USB-C port for input and output. Thanks to Power Delivery, the USB-C port delivers up to 60W of output and 45W of input.

In case you need even more power, the Omni 20+ even features an AC outlet with 100W output. That means you can charge the 15-inch MacBook Pro at full speed. As if that wasn’t enough, the Omni 20+ delivers up to 10W of wireless charging output.

Finally, the small OLED display shows how much charge is left, how much wattage the Omni 20+ is outputting at, and the estimated amount of time left until the battery dries up.

All of this comes at a hefty $199 cost. The Omni 20+ is also very heavy, even for a 20,000mAh portable battery. However, this is one of the most options out there.


That’s it for our list of the best 20,000mAh power banks available. We’ll update this post with more options once they are released.
